Brevibacllus brevis

Description and Significance

Brevibacillus-brevis is a rod shaped Gram-positive bacterium that inhabits air, soil, water, and decaying matter. This aerobic bacterium is motile and forms spores. This bacterium is medically significant as the antibiotics tyrocidine and gramicidin were first isolated from it. Brevibacillus-brevis is also an important nitrogen fixer, auxin and ammonia producer, antifungal, and antibacterial that is beneficially utilized in agriculture.

Genome Structure

The genome size of Brevibacillus-brevis is around 4-5 megabase pairs and is a single circular chromosome. In more detail it can be described as a gram-positive, rod-shaped and spore-forming.

Cell Structure, Metabolism and Life Cycle

Brevibacillus brevis gains energy through aerobic respiration and it breaks down nutrients like glucose via glycolysis and the pentose phosphate pathway. It can also ferment sugars under anaerobic conditions to generate ATP.

Ecology and Pathogenesis

Habitat; symbiosis; biogeochemical significance; contributions to environment.
