what does MSA plate stand for? A Gram - B. Staphylococcus C. E. coli D. Salmonella E. Gram +
Homework Answers
MSA Mannitol Salt Agar plate allow differential gram negative bacteria specifically staphylococus as mannitol support fermentation during anaerobic condition while high salt concentration prevent growth of other gram negative bacteria.
Hope it's ok..thanks

On a mannitol-salt agar plate, a bacterium grows on the plate, and turns medium color from light orange to bright yellow. The color indicator is phenol red. This bacterium must be capable of: Select one: O a. Fermenting lactose to make acidic by-products. O b. Utilizing citrate as a main carbohydrate source to grow. O c. Fermenting glucose to make acidic products, which lowers the pH of the MSA agar. O d. Fermenting mannitol to make acidic products,...

The bacterium E. Coli is a Gram-negative rod that is 1mM x 2mM. Each E. Coli cell contains a chromosome of 4 x 106bp of double-stranded DNA. Since 1 kilobase pair (kbp) of double-stranded DNA is 0.340mM in length, what is the length of the E. Coli chromosome? (1 kbp = 1000 base pairs, and 1mM = 10-6meters). A single colony-forming unit (CFU) of E. coli contains 109 cells. If you were to join all the E. coli chromosomes contained in that colony together...
