Microbial ecology (or environmental microbiology) is the ecology of microorganisms: their relationship with one another and with their environment. It concerns the three major domains of life— Eukaryota , Archaea , and Bacteria —as well as viruses . [ 2 ]
Microecology means microbial ecology or ecology of a microhabitat. It is a large field that includes many topics such as: evolution, biodiversity, exobiology, ecology, bioremediation, recycling, and food microbiology. [1] It can also refer to a hybrid urban network at the scale of the neighbourhood. [2]
Chemolithoautotrophic bacteria derive nutrients and energy from the geological activity at Hydrothermal vents to fix carbon into organic forms. Viruses are also a part of the hydrothermal vent microbial community and their influence on the microbial ecology in these ecosystems is a burgeoning field of research. [1]
The branches of microbiology can be classified into applied sciences, or divided according to taxonomy, as is the case with bacteriology, mycology, protozoology, virology, phycology, and microbial ecology.
These include the buccal region (especially cavities in the gingiva), rumen, caecum etc. of mammalian herbivores or even invertebrate digestive tracts.In the case of mammalian gastrointestinal microecology, microorganisms such as protozoa, bacteria, as well as curious incompletely defined organisms (such as certain large structurally complex Selenomonads, Quinella ovalis "Quin's Oval ...
Microbial physiology: the study of how the microbial cell functions biochemically. Includes the study of microbial growth, microbial metabolism and microbial cell structure; Microbial pathogenesis: the study of pathogens which happen to be microbes; Microbial ecology: the relationship between microorganisms and their environment
Metagenomic approaches to the analysis of complex microbial communities allow the targeted screening of enzymes with industrial applications in biofuel production, such as glycoside hydrolases. [84] Furthermore, knowledge of how these microbial communities function is required to control them, and metagenomics is a key tool in their understanding.
A microorganism, or microbe, [a] is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells.. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India.
