[pct-l] Question about Boiling Lake



I think that we need to deferentiate betweeen an anerobic environment and a
aerobic environment.  You do not think that Blue green algae can grow in
that environment.  Blue green are in an algal category by themselves since
they more closely resemble bacteria, and are capable of doing many of the
things that bacteria do.  News to me that they are sulphur sensitive!!!

There is a class of chemosynthetic bacteria, that specifically use sulphur
as a substrate; these also produce a range of pigments, but are usually
growing in an anaerobic or low oxygen environment.
