2020年10月15日 · Bacillus subtilis, hay bacillus, or grass bacillus was one of the first Gram-positive bacteria to be studied. It is an aerobic, rod-shaped spore-forming microorganism that can spread in extreme cold, heat, and even disinfected environments. It transfers to the gastrointestinal tracts of animals and humans via the soil.

Metataxonomic insights into the microbial ecology of farm-scale hay ...
2022年8月11日 · We assessed the diversity of viable bacterial communities of hay (unfermented dry forage) and grass or legume (GL) and corn (C) silage to deepen our knowledge of how inoculant addition drives microbial occurrence patterns on dairy farms. Forage samples were collected from 24 dairy farms over two sampling periods.

Bacillus subtilis (Ehrenberg, 1835) Cohn, 1872 - GBIF
Bacillus subtilis, known also as the hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium, found in soil and the gastrointestinal tract of ruminants, humans and marine sponges. As a member of the genus Bacillus, B. subtilis is rod-shaped, and can form a tough, protective endospore, allowing it to tolerate extreme ...
