Methods of Microbial Control -Part 1

This method of pasteurization involves passing a fluid such as milk through a tube at 72 degrees Celsius for 15 seconds.

True or False.  Bacteria that have been lyophilized can be brought back to a living state of metabolic activity.

Which of these would be best suited to sterilization by the application of dry heat in an oven rather than an autoclave?

Which of the following is not recommended for sterilization in an autoclave?

An autoclave delivers __________ as much heat energy to the surface of an object than boiling or steaming at normal atmospheric pressure.

When using boiling water to reduce or eliminate microbes, why is it necessary boil for a longer period at higher altitudes than lower ones to achieve the same effect?

The lowest temperature at which all microbial growth stops when incubated for 10 minutes at a pH of 7.

This term describes the reduction of microbes from the surface of an object.

You work in a disinfectant testing facility and are asked to determine which of a series of chemical disinfectants is most effective at controlling  the growth of common household germs such as Staphylococcus aureus, Escherichia coli and others at a low enough concentration to be less damaging to the skin and mucus membranes of the user. Which of the following would be the best way to evaluate this?

These agents of microbial control kill all pathogens and other life forms when applied correctly.
