What are the most likely point in nutrient media preparation or later at which contamination may
be introduced? What signs would indicate contamination? What is the source of the following
elements in nutrient media prepared? (See Medium Recipes pg.20 of Microbiology Laboratory
Theory & Applications) Carbon? Nitrogen? What are the two types of nutrient media prepared
in BIQL3200L?
Solution
Most likely points of contamination introduction in nutrient media
Signs of contamination.
Since the media contents are not provided in the question , I will give you the general sources.
Sources of Carbon is the Glucose, glycerol, tryptone soy, casein soy digest, beef extract, potato
dextrose…etc
Sources of Nitrogen is Yeast extract, NH4Cl, Beef extract..etc
