Final answer:
EMB Agar will show green or purple colonies for lactose fermenters and colorless colonies for non-lactose fermenters. Blood Agar will display clear zones around hemolytic Streptococcus indicating lysis of red blood cells, while non-hemolytic Staphylococcus will show white colonies.
Step-by-step explanation:
The appearance of EMB Agar and Blood Agar in an Anaerobe Chamber is dependent on the type of bacteria growing on these media. EMB Agar (Eosin Methylene Blue Agar) is a selective medium that differentiates between lactose fermenters and non-lactose fermenters. Lactose fermenters will produce metallic green or deep purple colonies, whereas non-lactose fermenters will show colorless colonies.
Blood Agar, on the other hand, is a differential medium that is enriched with red blood cells. It can show different types of hemolysis; the presence of hemolytic Streptococcus will lead to a transparent, clear area in the agar where the red blood cells have been lysed, while non-hemolytic bacteria like Staphylococcus appear as white colonies without changing the red color of the agar.
