How is chocolate media different than blood agar media? 1.Blood agar contains more bacterial inhibitors to previous growth of fastidious organism. 2.blood agar has intact red blood cells 3.chocolate allows for the determination of lysis,allowing it be differential media. 4.chocolate is primarily used for enteric organisms while blood is used for fastidious organism.
Why is the chemical makeup of a complex media unknown? Differential media agar plates often change color. What is the color change actually telling us about the microbe? What would happen if the color indicator was excluded when making a differential media agar plate? Would the microbes behave differently on plates without the color indicators?

What is the carbon source, nitrogen source, selective chemicals, media classification for each agar plates? Alkaline Soy Flour Mannitol-NC Agar SpM-NC (Nystatin) Agar Glycerol Arginine-NC Agar Acidified ISP medium 2-NC agar
What is the purpose of adding 0.1% agar to the trypticase nitrate broth when conducting the nitrate reduction test? 1. The addition of agar creates a solid surface for inoculation. 2. The addition of agar helps to create an anaerobic environment, encouraging nitrate reduction. 3. The addition of agar helps to create an aerobic environment, encouraging nitrate reduction. 4. The addition of agar allows for the detection of motility. There should only be 1 answer. Thank you!
consider the organisms S. aureus grown in the media mannitol salt agar plate and tryptic soy agar plate. , and E. coli grown in the media tryptic soy agar plate and eosin methylene blue plate Where are they found? What is know about their metabolic capabilities as related to the media?
