I am searching for info on detailed structure of amoeba or any
protozoa. I would like to know which elements of nature constitute
nucleus, moleculer structure etc.
Aim is to figure out what makes that nucleus to 'feel' hungry and look

Lets say a stick of unsalted, annato-free, purely-natural, organic,
cow-milk butter is placed in an small box free of air, oxidants, and
any other agents that could cause rancidity. In addition, lets also say
that this box is free of all living organisms, excluding non-acidic

I am curious as to whether any anaerobic bacteria can digest and
metabolize lipids? If so, do these bacteria produce foul-odors directly
as a by-product of their lipid-consumption?
Thanks,

Here is my theoretical ["magical" is probably a better word] situation
I have a box [which contains a stick of butter] that does not let in
anything foreign microbes other than anaerobic bacteria. Also, the pH
of the butter is [for some mircalous reason] at least 7 before, during

 I am a student doing research in environmental microbiology particularly interested in biodegradation. Can anyone send me any information or a protocol for 16S Ribosomal RNA based identification of microorganisms.

Can anyone give any information on photoautotrophs, photoheterotrophs,
chemoautotrphs and chemoheterotrophs?

I am aware that most cases of body odor involve bacteria feeding on
organic substances in the sweat, sebum and dead skin cells. My question
is, is body odor also caused by rancidity of body oils and other
substances?

Dear Sir,
 I came across a web posting online by Davin C. Enigl which was posted a couple of years ago. I'm not sure if he is still here, but I would very much like to obtain the articles that he wrote on the subject.
 I found his message on the following link. http://www.bio ...

I need pics of E-coli.  Does anyone have some they can share with me?  I would appreciate any help available.
Thanks so much,

First, sorry if this is too far off-topic, but I figured I could
perhaps enlist the expertise of the people in this group to help me
with this.  As an intro, I am an amateur brewer and winemaker.  I have
a basically no knowledge of micro-organisms that aren't Saccharomyces
