how long can bacteria survive power outage

SMinNC - I think you did miss the important point:

I was meaning we had confirmed 5 days(at this time). But not how long(as in, a week, 2 weeks?) they will survive.

-
But as in my last post, with the link to the other forum. Now we can see they will live in a canister for 24 weeks.
Which still means we don't know how long they can survive without power. But we're up to 24 weeks now.

That link is kind of hard to read, with the quotes not showing as quotes. And I started doing some skimming here and there.
But from what I saw, it started right up. Sucking up ammonia dosed like you would for a fishless cycle, over night.
 
I went through the post, and found some of the better points.

Here ya go......



This first excerpt was further down the thread, but kind of on its own subject. So I've posted it here.

on boxing day at lunchtime i noticed that one of my tanks was rather cloudy and the fish gasping, i noticed that the filter taps were in the off position, and realised that they had been like that for at least 2 weeks:eek::eek: i removed all the fish and put in another tank (they were all alive and none have died) i tested the water and had ammonia readings of 2 and nitrite readings of 1. i turned the filter back on and left the water as it was. today (3 days later) i have zero readings for ammonia and nitrite:)

10 weeks ago i turned off a fluval 404 and put it in a corner of the fishhouse out of the way without cleaning it. it still has all the gunk in it and all the water. i am now going to use it to fishlessly cycle a 4ft tank.

any guesses as to how long it will take?

experiment started today star date two six zero one two zero zero nine
at 1500hrs. enough ammonia added to get a reading of 2ppm :)

5 hours later and i have just tested for nitrite:) there is a reading but only slight, compared with a test from a mature tank and using the api liquid test there is a slight colour change from the zero reading but it is still less than 0.25. i will test again tomorrow morning. i know for definite that i wouldnt have got such a reading from starting from scratch with new filter:D

this is going better than i thought. tested 0945 27-01-09
ammonia has dropped to 1ppm and nitrite is up to .25ppm:eek:

before switching these filters off (save on the leccy) they had been running in a bucket and were fed a couple of drops of ammonia twice a day so they were well mature when switched off. (realized i wasnt going to use them in the forseeable future).

stored on the floor in corner of fish house i suspect the temp was around 15 to 16C

1945hrs 27-01-09 CYCLED:D very surprised at the speed so tested twice, so thats a little over a day ammonia and nitrites at zero

Are you going to try 5ppm Ammonia and see if that goes as quickly?

already added:D except i overdosed by accident and its at around 8ppm:rolleyes:

fluval 404 been switched off and standing in the corner of my fish house at an approx temp of 15C for 24 weeks.

1 ft x 1ft x 15inches tank which has about 1 inch of coral gravel and 2 inches of standing water from about 16 weeks ago, a load of snails in there.

filled with water today at 1230 and tested. (water been standing in butt for 2 weeks so no dechlorinator added)

ammonia 1ppm (probably because of all the snail detritus etc)
nitrite 0
Ph 8.0
temperature at 70f (but heater in there to lift it to about 76f)

ammonia added to take it to somewhere between 4 and 8 ppm (api liquid test)

FLUVAL SWITCHED ON:D:D

just tested the water

temp 78f

ammonia 2ppm

nitrite 0ppm

nitrate 20ppm

so nearly half a year with the bacteria in the dark without oxygen. it would appear that the nitrite consuming bacteria are hardier than the ammonia eating bacteria hence the zero reading.

well the ammonia has gone somewhere because it was somewhere between 4 and 8ppm yesterday and i had zero nitrate which i forgot to put on post. now i have nitrate an a lot less ammonia so i was assuming that the nitrite munchers are eating nitrite as fast as the ammonia munchers can produce it. i havent a clue what all the technical terms are:D

tested last night and all ammonia has gone, never had a nitrite reading at any stage its always been zero.:D

hardy little buggers these bacteria aren't they:)

This is the kind of stuff I like to read.
People like us, well most of us, from what I gather. Doing something simple, without all that sci-fi mumbo jumbo and them crazy numbers used in that new math. ;) LOL


Put that in yur fluval and smoke it. :P
 
Storage recommendation for nitrifying bacteria from "Bergey's manual of systematic bacteriology". This is the guidebook that microbiologist use grow bacteria in the lab.

Nitrifying bacteria can survive starvation for more than one year when kept at 17C in liquid medium. Nevertheless, cells should be transfered to fresh media every four months.
Simple terms - if the media is wet and kept a room temperature you've got 4 months to get them some food without worrying about sending the tank into a cycle. After that you'll probably have a minicyle for up to a year. These little buggers are pretty rough and tough.

^ at 10 weeks the bacteria where just starting to feel the munchies.
