Dead Bacteria

Bacteria will die only after LONG periods of time. People have gone several hours without power and not had a massive bacteria die off.
Any bacteria that does end up dying, a very unnoticeable amount, will be replaced quickly

I wouldn't worry about it. I try and keep the media moist, as long as its not drying out while you do your maintenance you should be fine.

Completely inaccurate and incorrect.
Depending on the species, endosporulation, and metabolic abilities the bacteria in your tank can survive for several days, weeks, months or even years. These little buggers are tough.
Please do a little research before you make this type of guess.
Actually both of you are correct. Some of the bacteria is aerobic meaning without oxygen it would die pretty fast. Some is anaerobic which could live much longer.
H3D I'm sorry you are incorrect.
Bacteria die at approximately the same rate as they grew when food is scarce. So for Nitrobacter. sp. with an optimal growth time of 10 hours this will take one to several days or even up to several weeks in colder temps (Bio-spira).
Second due to most aquatic bacteria's slow growth rates the depletion of O2 in the stationary water is really quite slow. It can take more than a day to reach a completely anaerobic conditions. Also, as long as there is a unbroken water column exposed to air dissolved oxygen will diffuse into most areas. So the chances of obligate aerobes being without oxygen is very, very, low. Unless you have a canister filter that you turn the shutoff valves closed and leave shut for several days you not going to get completely anaerobic conditons.
