Thanks to everyone who replied to my request for assistance in locating
a recent article reference that I'd lost. In case anyone might be
interested, here is the reference:
Journal of Phycology 30(3):431-438. Rothschild, et al. 1994
Metabolic activity of microorganisms in evaporites.
I have samples of gypsum from deposits in Oklahoma that appear
to contain various cyanobacteria, although I am not familiar
enough with them to be 100% certain. If anyone can offer
some assistance in regards to their identification I'd like to
hear from them.
