In the lab we tested our very experience bacteria off of our tongue and smeared it on a parentage nutrient agar-agar plate, sheep blood to be exact.

We collect the bacteria from the inside of the address and grow them in specially alert petri helpes. descent agar it contains .5% sheeps blood is an excellent medium for give bacteria with nutrients and an surroundings in w hich we can see them grow. Materials: Blo! od Agar dish Cotton Swab Stick mark Microscope Incubator Procedures: 1. Prepared petri dishes should be refrigerated until use and endlessly stored upside down. This keeps condensation which forms in the lid from drop onto and disrupting the bacteria growing surface. 2.When ready to use, let dishes come to path temperature before taking samples. 3.Collect bacteria from each hole using...If you want to communicate a full essay, order it on our website: BestEssayCheap.com
