In my result i isolate bacillus sp on mannitol salt agar but i expect that this media has deoration or expaired
There is growth on a Mannitol Salt Agar (MSA) plate but it does not ferment Mannitol.
Yes it does
yes.
Yes
yes
Micrococcus roseus ferments sucrose, but no gas. Does not ferment lactose, glucose, or mannitol. Beta hemolitic. Catalase positive. Pink colonies of groth
Yes, it can ferment lactose. Mannitol Salt Agar is used to identify S.aureus. When it ferments D-mannitol, it produces an acid which turns the agar yellow from red. S.epidermidis will grow, but the agar remains red.
Mannitol Salts agar is a selective and differential media used to identify Staphylococcus sp. The media is selective due to the high salt concentration which prevents all but halophiles from growing. The media is differential due to the presence of mannitol and the indicator Phenol Red. Staphylococcus aureus can ferment mannitol and produce lactic acid as a result. The media contains an indicator called Phenol Red which turns yellow in low pH environments. This results in a yellow halo around the S.aureus colonies. Staphylococcus epidermidis cannot ferment mannitol and so the colour of the media around these colonies does not change. Certain vibro species and other halophiles may grow on these plates some of these appear pink and some may be able to ferment mannitol leading to false positives. S.epidermidis is a normal commensal organism and grows on the skin. S.aureus is a potential pathogen, antibiotic strains exist and can be hospital accquired infections.

By adding polyhydroxy comp. as Glycerol, Mannitol , H3BO3 acts as strong acid and we can titrate it.
Bacillus coagulans is a lactic acid forming bacterial species within the genus Bacillus.
Yes, acid is produced but gas is not.
Bacteria which live on the walls of the intestine help in the production of vitamins. Bacillus valgatus is a bacteria is capable of producing thiamine from lactic acid. Bacillus subtilis and escherichia coli are capable of producing riboflavin and pyridoxine.

The are gram negative bacillus shaped bacteria. They are facultative anaerobic bacteria. They ferment the glucose to produce acid and gas. They ferment the sulfur containing amino acids to produce H2S gas. They do not ferment the lactose.
Bacillus subtilis E. coli Pseudomons fluorenscens streptococcus faecilis most bacteria can grow on nutrient agar

B. subtilis is indeed a Gram positive rod.However, there is confusion as to whether it is an obligate aerobe or a facultative anaerobe. Although classed as an obligate aerobe, it has been shown to grow under strict anaerobic conditions.

Mannitol salt agar is used for the isolation of staphylococci which is found normally on skin (S. aureus). The selectivity is obtained by the high salt concentration that inhibits growth of many groups of bacteria.
