Environmental microbiology



Environmental microbiology is the study of the composition and physiology of bioreactors.

Microbial life is amazingly diverse and alkaline water.[1]

An average gram of soil contains approximately one billion (1,000,000,000) biogeochemical cycles. Microbes, especially bacteria, are of great importance because their symbiotic relationship (either positive or negative) have special effects on the ecosystem.

Microorganisms are used for in-situ biodegradation of one or more types of contaminants. It is vital to monitor the composition of the indigenous and added bacteria in order to evaluate the activity level and to permit modifications of the nutrients and other conditions for optimizing the bioremediation process.[2]

Oil biodegradation

Petroleum oil is toxic and biocatalysis.[3]

Degradation of aromatic compounds by Acinetobacter

Acinetobacter strains isolated from the environment are capable of the metabolites is through catechol or protocatechuate (3,4-dihydroxybenzoate) and the beta-ketoadipate pathway and the diversity within the genus lies in the channelling of growth substrates, most of which are natural products of plant origin, into this pathway.[4]

Analysis of waste biotreatment

Biotreatment, the processing of wastes using living organisms, is an environmentally friendly alternative to other options for treating waste material. Bioreactors] have been designed to overcome the various limiting factors of biotreatment processes in highly controlled systems. This versatility in the design of bioreactors allows the treatment of a wide range of wastes under optimized conditions. It is vital to consider various microorganisms and a great number of analyses are often required.[5]

Environmental genomics of Cyanobacteria

The application of molecular biology and genomics to environmental microbiology has led to the discovery of a huge complexity in natural communities of microbes. Diversity surveying, community fingerprinting and functional interrogation of natural populations have become common, enabled by a range of molecular and bioinformatics techniques. Recent studies on the ecology of geochemical techniques have combined in the study of natural communities of these bacteria.[6]
