2nd International Conference on Microbial Ecology & Eco Systems July 11-12, 2018 Toronto, Ontario, Canada
(10 Plenary Forums 2 days 1 event)

Plant and Agricultural Microbiology is the study of the organisms and environmental conditions that cause disease in plants, the mechanisms by which this occurs, the interactions between these causal agents and the plant (effects on plant growth, yield and quality), and the methods of managing or controlling plant disease. It also interfaces knowledge from other scientific fields such as mycology, microbiology, virology, biochemistry, bioinformatics, etc.

Plant disease is an impairment of the normal state of a plant that interrupts or modifies its vital functions. All species of plants, wild and cultivated alike are subject to disease. Although each species is susceptible to characteristic diseases, these are, in each case, relatively few in numbers. The occurrence and prevalence of plant diseases vary from season to season, depending on the presence of the pathogen, environmental conditions, and the crops and varieties grown. Some plant varieties are particularly subject to outbreaks of diseases; others are more resistant to them.

Importance and Scope: Control of plant diseases is crucial to the reliable production of food, and it provides significant reductions in the agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated populations carry inherent disease resistance, but there are numerous examples of devastating plant disease impacts, as well as recurrent severe plant diseases. However, disease control is reasonably successful for most crops. Disease control is achieved by use of plants that have been bred for good resistance to many diseases, and by a plant, cultivation approaches such as crop rotation, use of pathogen-free seed, appropriate planting date and plant density, control of field moisture, and pesticide use. Across large regions and many crop species, it is estimated that diseases typically reduce plant yields by 10% every year in more developed settings, but yield loss to diseases often exceeds 20% in less developed settings. Continuing advances in the science of plant pathology are needed to improve disease control, and to keep up with changes in disease pressure caused by the on-going evolution and movement of plant pathogens and by changes in agricultural practices.

Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food, including the study of microorganisms causing food spoilage. "Good" bacteria, however, such as probiotics, are becoming increasingly important in food science. In addition, microorganisms are essential for the production of foods such as cheese, yoghurt, bread, beer, wine and, other fermented foods.

Importance and Scope: Food safety is a major focus of food microbiology. Pathogenic bacteria, viruses and toxins produced by microorganisms are all possible contaminants of food. However, microorganisms and their products can also be used to combat these pathogenic microbes. Probiotic bacteria, including those that produce bacteriocins, can kill and inhibit pathogens. Alternatively, purified bacteriocins such as nisin can be added directly to food products. Finally, bacteriophages, viruses that only infect bacteria, can be used to kill bacterial pathogens. Thorough preparation of food, including proper cooking, eliminates most bacteria and viruses. However, toxins produced by contaminants may not be liable to change to non-toxic forms by heating or cooling the contaminated food. Fermentation is one of the methods to preserve food and alter its quality. Yeast, especially Saccharomyces cerevisiae, is used to leaven bread, brew beer and make wine. Certain bacteria, including lactic acid bacteria, are used to make yoghurt, cheese, hot sauce, pickles, fermented sausages and dishes such as kimchi. A common effect of these fermentations is that the food product is less hospitable to other microorganisms, including pathogens and spoilage-causing microorganisms, thus extending the food's shelf-life. Some cheese varieties also require moulds to ripen and develop their characteristic flavours. To ensure the safety of food products, microbiological tests such as testing for pathogens and spoilage organisms are required. This way the risk of contamination under normal use conditions can be examined and food poisoning outbreaks can be prevented. Testing of food products and ingredients is important along the whole supply chain as possible flaws of products can occur at every stage of production. Apart from detecting spoilage, microbiological tests can also determine germ content, identify yeasts and moulds, and salmonella. For salmonella, scientists are also developing rapid and portable technologies capable of identifying unique variants of Salmonella. Polymerase Chain Reaction (PCR) is a quick and inexpensive method to generate numbers of copies of a DNA fragment at a specific band ("PCR (Polymerase Chain Reaction)," 2008). For that reason, scientists are using PCR to detect different kinds of viruses or bacteria, such as HIV and anthrax based on their unique DNA patterns. Various kits are commercially available to help in food pathogen nucleic acids extraction, PCR detection, and differentiation. The detection of bacterial strands in food products is very important to everyone in the world, for it helps prevent the occurrence of foodborne illness. Therefore, PCR is recognized as a DNA detector in order to amplify and trace the presence of pathogenic strands in different processed food.

Antibiotic resistance is a natural phenomenon. When an antibiotic is used, bacteria that can resist that antibiotic have a greater chance of survival than those that are "susceptible."

Modern Antibiotics Development of new antimicrobial drugs is an essential component in the effort to remain ahead of emerging microbial resistance. However, when new antibiotics are used with unrestrained enthusiasm, a predictable consequence is the further expansion of resistance. This problem is well known to the infectious diseases specialist and is increasingly appreciated by the nonspecialist and the public. A far more sensible strategy is to identify new ways to use these drugs to increase the duration of their usefulness. New methods to optimize antibiotic selection, dose, and duration of therapy are being investigated.

Importance and Scope: Numerous pathogens that have become resistant to commonly used antibiotics have been described in various contexts, including drug-resistant methicillin-resistant Staphylococcus aureus (MRSA), Streptococcus pneumonia, and Mycobacterium tuberculosis. Antibiotics-2015 is the premier event that brings together a unique and International mix of experts, researchers and decision-makers from both academia and industry across the globe to exchange their knowledge, experience and research innovations. There is a renewed interest in the antibiotic sector, which is evident from the most recent patents and investments. Bacterial vaccines and new antibiotic classes are gaining a tremendous amount of attention with several product candidates in clinical development. This conference focuses exclusively on antibiotics, bacterial vaccines, and other emerging antibacterials.

Soil science is a radiant culture media for the extension and advancement of grouped microorganisms. The soil is related idle static material, however, a medium beating with life. Soil at present is accepted to be a dynamic or living framework containing numerous particular groups of microorganisms and among them like parasites, actinomycetes, protozoa and infections square measure the principal fundamental. Micro-organisms make a truly little portion of the dirt mass and involve a volume of yet one-hundredth. Inside the higher layer of soil, the microbial population is high to a great degree that reduces the profundity of soil. Each creature or a gaggle of life forms square measure responsible for a chose correction or change inside the dirt. The respective session of this Microbiology Conference will focus on Maintenance of biological equilibrium, minimization of pollutants in agricultural soil by microbes, biofertilizers and biopesticides and related such areas which will bring forward the importance of soil microbiology

Microbes also play a key role in the nitrogen cycle. Bacteria in the soil convert atmospheric nitrogen into nitrates in the soil. Nitrates are an essential plant nutrient – they need the nitrogen for proteins - and the plants themselves provide food for livestock and other animals. The nitrogen locked in plant and animal proteins is then degraded into nitrates by microbes and eventually converted back into nitrogen by denitrifying bacteria. Compost heaps are a fantastic example of how effectively microbes break down organic matter. The mixture of garden weed, grass clippings and mouldy fruit and veg is decomposed rapidly by fungi and bacteria into carbon dioxide and plant compost containing nourishing nitrates and nitrites. Without the recycling power of microbes dead vegetation, carcasses and food waste would start piling up around us! In the UK 6.7 million tonnes of food waste is thrown away every year.

Metagenomic approaches are now commonly used in microbial ecology to study microbial communities in more detail, including many strains that cannot be cultivated in the laboratory. Bioinformatic analyses make it possible to mine huge metagenomic datasets and discover general patterns that govern microbial ecosystems. Metaproteomics proposed for the large-scale characterization of the entire protein complement of environmental microbiota at a given point in time. Two thousand and thirty-three proteins from the five most abundant species in the biofilm were detected, including 48% of the predicted proteins from the dominant biofilm organism Leptospirillum group II.

Ecumenical change is altering species distributions and thus interactions among organisms. Organisms live in concert with thousands of other species, some benign, some pathogenic, some which have little to no effect in intricate communities. Since natural communities are composed of organisms with very different life history traits and dispersal competency it is unlikely they will all respond to climatic transmutation in a kindred way. Disjuncts in plant-pollinator and plant-herbivore interactions under ecumenical change have been relatively well described, but plant-soil microorganism and soil microbe-microbe relationships have received less attention. Since soil microorganisms regulate nutrient transformations, provide plants with nutrients, sanction co-esse among neighbors, and control plant populations, transmutations in soil microorganism-plant interactions could have paramount ramifications for plant community composition and ecosystem function.

Many industrial processes engender contaminated wastewater capable of causing earnest ecological harm that may result in heftily ponderous fines and prosecution if relinquished into the environment without felicitous pre-treatment. Conventional treatment systems can be very sumptuous to build and operate. MBD Energy offers industry partners potential for cost-preserving pre-treatment or full bioremediation (depending on the contamination type and rigor), together with potential for the engenderment of valuable biomass and algae-predicated products. Whether utilising cull strains of algae or bacteria, all MBD’s bioremediation solutions harness the puissance of nature to biologically convert industrial waste into biomass, which can be utilized for fuel, fertiliser, victuals or aliment – depending on the contamination type. Albeit bioremediation holds great promise for dealing with intractable environmental quandaries, it is consequential to agnize that much of this promise has yet to be realized. Concretely, much needs to be learned about how microorganisms interact with different hydrologic environments. As this under-standing increases, the efficiency and applicability of bioremediation will grow rapidly. Because of its unique interdisciplinary expertise in microbiology, hydrogeology, and geochemistry, the USGS will perpetuate to be at the forefront of this exhilarating and rapidly evolving technology.
 
Biodegradation is nature's way of recycling wastes, or breaking down organic matter into nutrients that can be utilized by other organisms. "Degradation" denotes decay, and the "bio-" prefix betokens that the decay is carried out by an immensely colossal assortment of bacteria, fungi, insects, worms, and other organisms that victual dead material and recycle it into incipient forms. In nature, there is no waste because everything gets recycled. The waste products from one organism become the aliment for others, providing nutrients and energy while breaking down the waste organic matter. Some organic materials will break down much more expeditious than others, but all will eventually decay. By harnessing these natural forces of biodegradation, people can reduce wastes and emaculate some types of environmental contaminants. Through composting, we expedite natural biodegradation and convert organic wastes to a valuable resource. Wastewater treatment additionally expedites natural forces of biodegradation. In this case the purport is to break down organic matter so that it will not cause pollution quandaries when the dihydrogen monoxide is relinquished into the environment. Through bioremediation, microorganisms are acclimated to emaculate oil spills and other types of organic pollution. Composting and bioremediation provide many possibilities for student research.
 

Most living things that are visible to the unclad ocular perceiver in their adult form are eukaryotes, including humans. However, a sizably voluminous number of eukaryotes are withal microorganisms. Microbial eukaryotes are a consequential component of the human gut microbiome. Eukaryotes that reside in the human gut are dispersed across the eukaryotic tree and their relationship with the human host varies from parasitic to opportunistic to commensal to mutualistic. Eukaryotes are one of the three domains of life and are defined by the presence of nuclei. Animals, plants, and fungi are the most visible clades of eukaryotes, but these are just three of the 70+ lineages, most of which are microbial.

A biofuel is a fuel that is engendered via contemporary biological processes, like agriculture and anaerobic digestion, rather than a fuel engendered by geological processes such as those involved in the formation of fossil fuels, such as coal and petroleum, from prehistoric biological matter. Biofuels can be derived directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes. Renewable biofuels commonly involve contemporary carbon fixation, like those that occur in plants or microalgae through the process of photosynthesis. Other renewable biofuels are made through the utilization or conversion of biomass (referring to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy-containing substances in three different methods: thermal conversion, chemical conversion, and biochemical conversion. This biomass conversion can result in fuel in solid, liquid, or gas form. Recently, lipases have been studied for biodiesel engenderment as whole-cell immobilized lipases. Each type of biocatalyst has its strengths and impotencies when it comes to reducing the contribution of the biocatalyst in the final cost of the biodiesel. Recent studies have been fixating on ameliorating catalysis performance and stability of the enzyme with the aim to reduce the lipase cost in the biodiesel conversion process. Different procedures have been developed for application mode of lipases. Solid state fermentation, whole-cell biocatalyst and immobilized lipase in different fortifies are the main studied modes.

A biogeochemical cycle or substance turnover is a pathway by that a chemical substance moves through both the biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) components of Earth. A cycle is a series of transmuting which comes back to the commencement point and which can be reiterated. The term "biogeochemical" tells us about the biological, geological and chemical factors. The circulation of chemical nutrients like carbon, oxygen, nitrogen, phosphorus, calcium, and dihydrogen monoxide etc. through the biological and physical world are kenned as "biogeochemical cycles".

Like organisms in any ecosystem, the microbes in the human body continually interact with one another, both directly and indirectly (the proteins and metabolites they engender are withal in constant interplay). Microbial communities exhibit synergistic interactions for enhanced bulwark from host defences, nutrient acquisition, and assiduousness in an inflammatory environment. Hundreds of different microbes persist in a single biofilm community. More virulent bacteria can forfend the biofilm from outside intrusion while other species inside the polymeric matrix fixate on obtaining nutrients for the community. As the biofilm forms and then develops, the collective genetic expression of microbes in the ecosystem changes significantly.

A biofilm is an amassment of microbial communities enclosed by a matrix of extracellular polymeric substance (EPS) and dissevered by a network of open dihydrogen monoxide channels. These communities adhere to manmade and natural surfaces, such as metals and teeth, typically at a liquid-solid interface. Their architecture is an optimal environment for cell-cell interactions, including the intercellular exchange of genetic material, communication signals, and metabolites, which enables diffusion of obligatory nutrients to the biofilm community. The matrix in which microbes in a biofilm are embedded forfends them from UV exposure, metal toxicity, acid exposure, dehydration and salinity, phagocytosis, antibiotics, and antimicrobial agents. The protective EPS and the unsurpassed metabolic multifariousness and phenotypic plasticity of microbes, likely expound how bacteria are able to persist in so many variants of environments, including those that are inhospitable to higher forms of life. By composing organized communities with other microbes, they can even further elongate their competency to acclimate and thrive in even the most truculent environments.

Microorganisms are called microbes for short. This class of life forms includes cellular life forms as well as the non-living crystals called viruses that parasitize living cells. The category called microbes includes viruses, bacteria, protists, some forms of fungus organisms and a few simple members of the animal kingdom. Microbes exist everywhere in abundance. Most are not harmful but some in category are known as pathogens and are harmful. The term pathogen indicates disease causing.
