Is bacterial alginate commercially available, other than getting
bacterial alginate from cultures of Pseudomonas aeruginosa in the lab?
If so, could anyone let me know which chemical companies sell
commercially available bacterial alginate, or how I could get it?

I am a second level teacher preparing a web site for use in my classroom as
part of a national project on the Microbiology module of the Biology
syllabus. If anybody has images of microbes or can direct me to useful
sites/resources for use in my site I would very much appreciate. I ...

Dear all, do any body know how to orally infect C57BL with listeria
moncytogene ? I  even used 1000000000 colonies to feed them in M
buffer (pH=8.0)vial feeding tube and the mice were still healthy. I
will appreciate you if you know it and can tell me. Best. WCY

Dear newsgroup members,
I recently found that under a light microscope, there are small
ameoba-like microorganisms in the commercial calf serum (Terra,
hyclone and so on). However, I can not detect them using PCR with

Certainly topics such as territoriality, xenophobia, kin selection and
aggression are part of evolutionary biology. They are aspects of our
biology which have persisted ever since Homo Sapiens have been around.
Evolutionary biology encompasses much more than just Homo Sapiens (which

I am finding out what type of polysaccharide should I use as a model
foulant for my experiments on fouling of reverse osmosis. The
experiments simulate the fouling effects of secondary wastewater
effluents in water reclamation treatment.

I plated the same sample on Std Plate Count agar and VRB agar (for
coliforms).  The results showed much higher counts on VRBA than that on SPC.
Isn't it supposed to have higher counts on SPC because it is less inhibitory
than VRBA??

I'm an undergraduate student who's curious about something mentioned in an
anatomy lecture:
My professor said that it was possible to have life without a cell, or
cells.

I was thinking about making a site about molecular biology. Not
another portal, but a site with actual content such as reference
material, databases, and papers. Is this a good idea? Is there a need
for such a site? I haven't been able to find any such sites through
