Description: First known as Vibrio subtilis, this bacterium was discovered by Christian Gottfried Ehrenberg in 1835.It was renamed in 1872 by Ferdinand Cohn. Bacillus subtilis (B. subtilis) is a Gram-positive, aerobic bacterium.It is rod-shaped and catalase-positive A number of poultry probiotics contain bacterial spores. In this study, orally administered spores of Bacillus subtilis germinated in the gastrointestinal (GI) tracts of chicks. Furthermore, 20 h after spores were administered, vegetative cells outnumbered spores throughout the GI tract. This demonstrates that spore-based probiotics may function in this host through metabolically active. 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 and humans. As a member of the genus Bacillus, B. subtilis is rod-shaped, and can form a tough, protective endospore, allowing it to tolerate extreme environmental conditions. B. subtilis has historically been classified.
Bacillus subtilis and Escherichia coli, for example, 63 each contain at least 20 hydrolases (4, 8). The large number of hydrolases in each 64 bacterium, combined with a high degree of functional and enzymatic redundancy 65 between them, has made it difficult to identify specific cellular functions for many 66 hydrolases Bacillus subtilis is an aerobic, Gram-positive, endospore forming bacterium that has the ability to produce and secrete the hydrolyzing carbohydrate enzyme, - amylase. Amylase is an enzyme that is used in various industries to rapidly degrade complex polysaccharides (e.g. starches) into smaller oligosaccharides

ABSTRACT The hasA gene from Streptococcus equisimilis, which encodes the enzyme hyaluronan synthase, has been expressed in Bacillus subtilis, resulting in the production of hyaluronic acid (HA) in the 1-MDa range. Artificial operons were assembled and tested, all of which contain the hasA gene along with one or more genes encoding enzymes involved in the synthesis of the UDP-precursor sugars. Spore formation by the bacterium Bacillus subtilis has long been studied as a model for cellular differentiation, but predominantly as a single cell. When analyzed within the context of highly structured, surface-associated communities (bioﬁlms), spore for-mation was discovered to have heretofore unsuspected spatial organization Bacillus subtilis (B. subtilis) is a potential and attractive host for the production of recombinant proteins. Different expression systems for B. subtilis have been developed recently, and various target proteins have been recombinantly synthesized and purified using this host. In this chapter, we Bacillus subtilis grows in the absence of oxygen using nitrate ammonification and various fermentation processes. Lactate, acetate, and 2,3-butanediol were identified in the growth medium as the major anaerobic fermentation products by using high-performance liquid chromatography. Lactate formation was found to be dependent on the lctEP locus, encoding lactate dehydrogenase and a putative. Abstract. Relatively little is known about the exact mechanisms used by Bacillus subtilis in its behavior as a biocontrol agent on plants.
