Exam 5: Environmental Influences and Control of Microbial Growth

The conditions used in an autoclave may be reproduced at home in:

If you have a food sample contaminated with anthrax spores, which sterilization approach would make sure the sample is free of spores without compromising the quality of the food sample-autoclaving or irradiation?

Disposable plasticware such as petri dishes can be sterilized using which of the following?

The use of oxygen as the terminal electron acceptor is called:

The membrane needs to remain __________ so that it can expand as cells grow larger and so proteins needed for solute transport can be inserted into the membrane.

Organisms adapted to grow at overwhelmingly high pressures are called:

Alkaliphiles use _________________ in addition to proton motive force to maintain pH.

Why is moist heat more efficient at killing microbes than dry heat? How does an autoclave kill microbes so efficiently?

Runoff from agricultural fields, lawns, and golf courses can cause an overgrowth of microbes due to:

The proteins and cell components of halophiles require remarkably high intracellular levels of what to maintain their structure?
