If we collected all the living material on Earth and weighed it, half of the accumulated biomass would be microorganisms. What is the most important role of bacteria in the natural environment? The 3-Domain System Based on ribosomal RNA gene sequences Almost all life is microbial! Their diversity enables them to thrive in extremely cold or extremely hot environments. In recent studies, the roles of indigenous microorganisms have been reported for detoxifying the MSW dumping sites and reducing the soil pollution. Bacteria may also be classified by living in a highly acidic versus alkaline environment, aerobic versus anaerobic, or autotrophic versus heterotrophic environment (Dick, R . ROLE OF MICROORGANISMS IN AQUACULTURE INTRODUCTION Microorganisms have major roles in pond culture, Microbes despite their small size have a huge impact on our lives, therefore understanding their role in the environment is important to the maintenance of our planet and preserving the diversity of plants and animals. This Bacteria are variously shaped spherical (cocci), rod-shaped (bacilli), spiral shaped (spirilla) and vibrio (comma-shaped). The microorganisms turn solar energy into sugars. Bioaugmentation is the process of adding engineered microbes in a system which act as abioremediators in order to quickly and totally eliminate complex pollutants. Microbes (or microscopic organisms) make up greater than half of the biomass of our planet. It has been long recognized that some of these microbes, such as mycorrhizal fungi or nitrogen fixing symbiotic bacteria, play important roles in plant performance by improving mineral nutrition. 1. Microbes are harmful but some are useful to our day to life. Hydrocarbons (HC) classified as alkanes, cycloalkanes, aromatics, polycyclic aromatics, asphaltines, and resins.
