Unit V: 
Identification and preservation of microorganisms

 

Preparation of microorganisms for light microscopy- wet mount and hanging drop technique. Staining techniques- simple staining, differential staining (Gram’s staining, acid fast staining, endospore staining). Special staining (capsule staining and flagella staining).

Preservation of microorganisms by sub culturing, overlaying cultures with mineral oil, lyophilization, use of liquid nitrogen.
