Question

Why should people know about Bacillus subtilis?

Bacillus subtilis metabolism?

Bacillus subtilis molecular biology, if symbiotic, interaction with host / partner?

Answer 1

Bacillus subtilis is a gram-positive bacteria. Found in the soil and gastrointestinal tract of ruminants. It is champion in the secreted enzyme production. This attractive property of Bacillus subtilis catches the attention of the industrial companies of biotechnology.

Bacillus subtilis is anaerobic microorganism which grows in the absence of oxygen. The major fermentation products were identified as lactate, acetate, 2,3 butanediol.

Lactate formation was found to be dependent on the lctEP locus, encoding lactate dehydrogenase and a putative lactate permease.

Anaerobic formation of 2,3-butanediol via acetoin involves acetolactate synthase and decarboxylase encoded by the alsSD operon.

Anaerobic acetate synthesis from acetyl coenzyme A requires phosphotransacetylase.

The molecular biology Bacillus subtilis says that it has become a model system for the study of many aspects of the biochemistry, genetics, and physiology of Gram-positive bacteria, and particularly of sporulation and associated metabolism.

It regulates the plant growth although its not having direct symbiotic relationship with plant as rhizobium with luminous plants.
