Bioprospecting of Extremophilic Microorganisms to Address Environmental Pollution

Journal of Visualized Experiments, 2021
Geothermal springs are rich in various metal ions due to the interaction between rock and water that takes place in the deep aquifer. Moreover, due to seasonality variation in pH and temperature, fluctuation in element composition is periodically observed within these extreme environments, influencing the environmental microbial communities ...

Shape-Based Classification of Environmental Microorganisms

2014 22nd International Conference on Pattern Recognition, 2014
Occurrence of certain environmental microorganisms and their species is a very informative indicator to evaluate environmental quality. Unfortunately, their manual recognition in microbiological laboratories is very time-consuming and expensive. Therefore, we work on an automatic method for shape-based classification of EMs in microscopic images. First,

Genomic islands in pathogenic and environmental microorganisms

Nature Reviews Microbiology, 2004
Horizontal gene transfer is an important mechanism for the evolution of microbial genomes. Pathogenicity islands — mobile genetic elements that contribute to rapid changes in virulence potential — are known to have contributed to genome evolution by horizontal gene transfer in many bacterial pathogens.

Plant Growth-Promoting Microorganisms for Environmental Sustainability

Trends in Biotechnology, 2016
Agrochemicals used to meet the needs of a rapidly growing human population can deteriorate the quality of ecosystems and are not affordable to farmers in low-resource environments. Here, we propose the use of plant growth-promoting microorganisms (PGPMs) as a tool for sustainable food production without compromising ecosystems services.

Environmental and Human Pathogenic Microorganisms

2014
As the study of interactions between pathogenic microorganisms and their environment is part of microbial ecology, this chapter reviews the different types of human pathogens found in the environment, the different types of fecal indicators used in water quality monitoring, the biotic and abiotic factors affecting the survival and the infectivity of ...

Influence of microorganisms on the environmental fate of radionuclides

Endeavour, 1996
Microorganisms have a significant influence on the environmental fate of radionuclides in aquatic and terrestrial ecosystems with a multiplicity of physico-chemical and biological mechanisms effecting changes in mobility and speciation. Physico-chemical mechanisms of removal include association with extracellular materials, metabolites and cell walls ...

The Role of Microorganisms in Remediation of Environmental Contaminants

2021
Environmental pollution by heavy metals, hydrocarbons, pesticides, dyes and other xenobiotic compounds is increasing day by day. Reclamation of these contaminants is of utmost importance for sustainable development. Various anthropogenic activities like industrial waste, mining, use of pesticides, deforestation and automobile emissions added a ...

DEGRADATION OF AZO DYES BY ENVIRONMENTAL MICROORGANISMS AND HELMINTHS

Environmental Toxicology and Chemistry, 1993
Abstract The degradation of azodyes by environmental microorganisms, fungi, and helminths is reviewed. Azo dyes are used in a wide variety of products and can be found in the effluent of most sewage treatment facilities. Substantial quantities of these dyes have been deposited in the environment, particularly in streams and rivers.

Research progress in genomics of environmental and industrial microorganisms

Science in China Series C: Life Sciences, 2009
Microbes contribute to geochemical cycles in the ecosystem. They also play important roles in biodegradation and bioremediation of contaminated environments, and have great potential in energy conversion and regeneration. Up to date, at least 150 genomes of non-pathogenic microbes have been sequenced, of which, the majority are bacteria from various ...
