Mannitol salt agar. An MSA plate with Micrococcus sp. (1), Staphylococcus epidermidis (2) and S. aureus colonies (3). Mannitol salt agar or MSA is a commonly used selective and differential growth medium in microbiology. It encourages the growth of a group of certain bacteria while inhibiting the growth of others.

Bacillus subtilis (/ bəˈsɪl.əs subˈtiː.lis /), [3][4] 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. [5][6][7][8] As a member of the genus Bacillus, B. subtilis is rod-shaped, and can form a tough ...
Binomial name. Bacillus megaterium. de Bary 1884. Bacillus megaterium is a rod-like, Gram-positive, mainly aerobic, spore forming bacterium found in widely diverse habitats. [1][2] It has a cell length up to 100 μm and a diameter of 0.1 μm, which is quite large for bacteria. [3] The cells often occur in pairs and chains, [1] where the cells ...
Mueller Hinton agar is a type of growth medium used in microbiology to culture bacterial isolates and test their susceptibility to antibiotics. This medium was first developed in 1941 by John Howard Mueller and Jane Hinton, who were microbiologists working at Harvard University. However, Mueller Hinton agar is made up of a couple of components ...
Bacillus (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota, with 266 named species. The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs. Bacillus species can be either obligate ...
Plate count agar (PCA), also called standard methods agar (SMA), is a microbiological growth medium commonly used to assess or to monitor "total" or viable bacterial growth of a sample. PCA is not a selective medium. The total number of living aerobic bacteria can be determined using a plate count agar which is a substrate for bacteria to grow on.
InterPro. GO:0004252. Subtilisin is a protease (a protein-digesting enzyme) initially obtained from Bacillus subtilis. [2][3][4][5][6][7][8] Subtilisins belong to subtilases, a group of serine proteases that – like all serine proteases – initiate the nucleophilic attack on the peptide (amide) bond through a serine residue at the active site.
MacConkey agar is a selective and differential culture medium for bacteria. It is designed to selectively isolate gram-negative and enteric (normally found in the intestinal tract) bacteria and differentiate them based on lactose fermentation. [1] Lactose fermenters turn red or pink on MacConkey agar, and nonfermenters do not change color.
