marine bacteria lifespan

[kaskiles]

Hi All,

This article:
http://www.biolbull.org/cgi/reprint/72/2/190.pdf

seems to indicate that the lifespan of marine bacteria is around 1/2 hour... The article seems old though, do you guys think the bacteria really die that quickly?

Thanks!

From this article:

"Bacterial half-life is approximately 24 hours"

From that article kaskiles it seems that there is a non bacterial factor effecting the population. They state that after storing a day or two in a jar the population increases up to 100,000x. It could be that they are being feed upon by other micro organisms or that in the natural environment a metabolic waste product from some living source keeps them in check. With the ability to double their population every 20 to 30 minutes there are undoubtly a number of natural circumstances that keep the pop within a range. It is not uncommon however for populations of bacteria or micro algae to fluctuate up and down every few days or weeks as the population increases, utilizes all available resources/ produces toxic waste/ predators addapt or increase, and then the pop crashes to near zero just to start all over again. And yes that seems to be an old article around the 30's when micro biology was not well understood and most science was done with things you could see with the naked eye.

I don't care what that stuff says, I NEVER feed my bacteria and they live for a weeks.....happy to frag some for you.
