Answer to Question #175313 in Microbiology for Aliya

Question #175313

1.     Bacteria A and Bacteria B are considered hardy bacteria and can survive in extreme environments when grown individually. However, when they are grown together in a closed environment (on an agar plate), Bacteria A thrives, while Bacteria B eventually dies off. 

a)     Calculate the density per cubic centimetre of Bacteria A on the agar plate if there are 1500 bacteria on a 100cm3 plate. (1 mark)

 

Dp=N/A

1500/1000^3

=1.5 x10^-6 

this right?

Density per cubic metre=\frac{N}{A}

N=1500

A=10003

=\frac{1500}{1000^3}=1.5\times10-6
