What is Bacillus subtilis for?

What is Bacillus subtilis for?

B. subtilis is often used as a probiotic preparation in the treatment or prevention of intestinal disorders. It is also used to produce antibiotics, as a fungicide, and in alternative medicine. This bacterium is part of the same family as Bacillus anthracis (anthrax).

What enzymes does Bacillus subtilis produce?

The Gram-positive bacterium Bacillus subtilis produces a variety of extracellular enzymes including six different proteases, an α-amylase, a levansucrase, several β-glucanases and at least two different lipolytic enzymes [5–8].

What is Bacillus subtilis culture?

Bacillus subtilis is one of the best characterized bacteria and is used as a model organism for Gram-positive bacteria. B. subtilis is a rod-shaped bacterium, which produces endospores that allow the survival of extreme environmental conditions including heat and desiccation.

Which enzymes are obtained from Bacillus subtilis?

What are biochemical tests used to determine?

Biochemical reactions used in biochemical tests depend on the presence of such bacteria. Such biochemical tests have been designed to measure the levels of bacterial enzymes which can be interpreted to accurately identify the species of bacteria they have been produced by.

Why are biochemical tests used to identify bacteria?

Microbial biochemistry tests shorten the time required to identify microbes, reduce costs, and ensure or enhance the accuracy of identification of an unknown sample. It is the fastest developing trend in microbial identification.

Why is Bacillus subtilis a model organism?

B. subtilis emerged as the Gram-positive model organism of choice largely because endospore formation became popular as a marvellously tractable system for studying fundamental aspects of cellular development and differentiation.

What is Bacillus subtilis fermentation product?

Bacillus subtilis Fermentation Product Super BSUB 1B and BS 5B are Bacillus subtilis fermentation products designed to provide guaranteed microbial plate count for animal feed applications. SUPER BSUB is useful when preparing products where a heat stable microbial is required, such as pelleting.

Does B. subtilis produce protease?

B. subtilis can be used for large-scale production of alkaline protease to meet present-day needs in the industrial sector. In the present study, a natural polymer gelatin was used with the nutrient agar medium to help in cell immobilization for maximum production of alkaline protease by strains of B.

What is biochemical tests for identification of bacteria?

The presence of catalase, gelatinase, oxidase, urease, for example, can be used to identify the species of bacteria. Biochemical reactions used in biochemical tests depend on the presence of such bacteria.

What is biochemical testing used for?

What is the purpose of using biochemical tests?

Is Bacillus subtilis positive for amylase?

Amylase plays an important role in biotechnology industries, and Gram-positive bacterium Bacillus subtilis is a major host to produce heterogeneous α-amylases.

Which bacteria is Utilised for amylase production?

Several bacteria have been shown are capable of producing a tremendous amount of alpha-amylase for industrial applications, these bacteria include Bacillus amyloliquefaciens, Bacillus licheniformis, and Bacillus stearothermophilus.
