The Lab Msa Promo On Vimeo Microbiology lab tutorial on mannitol salt agar (msa) specialized bacterial growth medium. examples of sterile msa as well as plates with growth of halophili. Interpretation of results: the interpretation of results from mannitol salt agar (msa) is based on the growth characteristics and the ability of bacteria to ferment mannitol. here is the general interpretation of results: mannitol fermenting bacteria (e.g., staphylococcus aureus): appearance: look for small, round, yellow colonies with a yellow. It is best to use a ready to use dehydrated powder (the one readily available on most suppliers of culture media). the medium has a concentration of 11.1 grams in every 100 ml of distilled water. sterilize through autoclaving at a temperature of 121 degree celsius for 15 minutes. allow the medium to cool down. Preparation of mannitol salt agar (msa) suspend 111 grams of mannitol salt agar in 1000 ml of distilled water. boil to dissolve the medium completely. sterilize by autoclaving at 15 lbs. pressure (121°c) for 15 minutes. if desired, sterile egg yolk emulsion (e7899) can be added to a final concentration of 5% v v after autoclaving.

Mannitol salt agar, or chapman agar, is a selective culture media used for the isolation, enumeration and differentiation of staphylococcus from clinical, food, antiseptic and cosmetic samples. msa's high salt concentration creates a selective environment that inhibits the growth of many bacteria except for salt tolerant staphylococcus species. Mannitol is a sugar alcohol that serves as the fermentable carbohydrate in the medium. it provides a source of energy for mannitol fermenting bacteria, allowing them to grow and thrive. sodium chloride. sodium chloride, also known as table salt, is a critical component of msa.
