what is the thermal death time?

what is the thermal death time for Bacillus subtilis and Staphylococcus aureus at 100 degrees celcius?

check_circleExpert Solution
Step 1: Bacillus subtilis is a gram positive, motile, rod shaped, and facultative aerobe that is
widely used to produce antibiotics. Staphylococcus aureus is another gram-positive bacterium
that is round in shape and found mostly in the upper respiratory tract.
Step 2:
Thermal death time is defined as the time taken to kill a microbe (usually a bacterium) at a
specific temperature. This method was initially used in food canning and later found
applications in cosmetics and pharmaceuticals
The thermal death time for the bacterium Bacillus subtilis at 100 degree Celsius is
approximately greater than 40 minutes.
The thermal death time for the bacterium Staphylococcus aureus at 100 degree Celsius is
approximately two minutes.
