Question

The x-axis shows the temperature and the y-axis shows the killing time. This is with respect to spores in a suspension. Curve a = 100,000 spores/ml and b= 1,000 spores/ml. Above curve a is the region of spores killed and below the region b is the region of spores survived. Which of the following do we comprehend from the above?

a.

Greater the spore concentration, more heat resistant the suspension

b.

Spores of a given strain, all have the same heat resistance

c.

Spores of the same strain have many spores of low heat resistance

d.

Spores of the same strain have very few spores of high heat resistance

Answer: (a).Greater the spore concentration, more heat resistant the suspension
