Growth of obligate anaerobes. The mixture of necessary nutrients can be used as a liquid medium, or a solidifying agent can be added. Agar agar is a natural polysaccharide produced by marine algae and is the most commonly used solidifying agent added to media (end concentration usually 1.5 % w/v). If hydrolysis of the agar is suspected, a silica gel is used as a replacement solidifying agent.
Best Answer: Selective media is a type of media that selects for the growth of one type of organism, while inhibiting the growth of others. An example of Selective media is MacKonkey Agar. MacConkeyâs Agar is selective for gram-negative bacteria, while inhibiting the growth of gram-positive bacteria.Blood Agar is solely a differential media. This media is a nutrient agar that is differential for hemolysis. It is based on the ability of a microorganism to destroy hemoglobin and red blood cells.nother good example of a media that is both selective and differential is EMB(Eosin-Methylene Blue.) EMB is selective for gram-negative bacteria, and differential for lactose fermentation.
