Question

Create a chart ( any way you would like)that summaries all the medias include in the chart if the media is selective, differential, enrichment-any special characteristics, what is it used for identification, what are the possible results ( and any color changes or any other ingredients needed to analyze) and what are the interpretations if those results.

Answer 1

Answer-

Name of media	Type of media	used for identification	Possible results	Interpretation
1.Blood agar media	Enrichment media	Supports for the growth of factidious organisms e.g Stre ptococcus.	Red color is observed	Beta hemolysis occurs.
2.MacConkey agar	Differential media	Used for identification of Enterobacteriacaeae (i.e.lactose fermenting and non-lactose fermenting)	Pink colonies OR colourless colonies	If pink colonies observed then lactose fermenters are present. If colourless colonies are observed then non lactose fermenters are present.
3.Mannitol salt agar	Selective and indicator media	Identification of S.aureus.	Yellow colony OR Colorless colony	If yellow colonies are observed then S.aureus i.e.mannitol fermenter is present.
4.Nutrient agar	General purpose media	supports the growth of all non- fastidious organisms	Variable test results occur.
