Exp. 11 : Diversity of Bacteria


Protocols



Questions

1. Why is it necessary tp rinse the smear excessively with water?

       To avoid the formation of crystallization of the stain on the slide.

2. Why Gram-positif bacteria purple in colour while Gram -negatif are red?


3. List some examples of bacteria and harmful Gram-positive bacteria and Gram-negative bacteria.
