MAC is a selective differential media selecting for Gram (-) bacteria , then differentiating between lactose fermentation and no fermenting organism. solidified agar during the streak plate method. closed culture: A closed culture has no additional nutrients added to the system, and waste products are not removed. Selenite F broth, tetrathionate broth, and alkaline peptone water (APW) are used to recover pathogens from fecal specimens. The act of organism culturing into the media is called inoculation or streaking. In fact, […] Proteins are often obtained from heart muscle, casein, fibrin or soya flour and is digested using woooww!
