competition for sulfide among colorless and purple sulfur bacteria in cyanobacterial mats.	the vertical zonation of light, o2, h2s, ph, and sulfur bacteria was studied in two benthic cyanobacterial mats from hypersaline ponds at guerrero negro, baja california, mexico. the physical-chemical gradients were analyzed in the upper few mm at < or = 100 micrometers spatial resolution by microelectrodes and by a fiber optic microprobe. in mats, where oxygen produced by photosynthesis diffused far below the depth of the photic zone, colorless sulfur bacteria (beggiatoa sp.) were the dominan ...	1986	11542103
vacuolated beggiatoa-like filaments from different hypersaline environments form a novel genus.	in this study, members of a specific group of thin (6-14 µm filament diameter), vacuolated beggiatoa-like filaments from six different hypersaline microbial mats were morphologically and phylogenetically characterized. therefore, enrichment cultures were established, filaments were stained with fluorochromes to show intracellular structures and 16s rrna genes were sequenced. morphological characteristics of beggiatoa-like filaments, in particular the presence of intracellular vacuoles, and the d ...	2011	21651683
