| radioisotope assay for the quantification of sulfate-reducing bacteria in sediment and water. | a radioisotope enrichment culture method was developed to estimate the physiologically active component of a population of sulfate-reducing bacteria in environmental water and sediment samples. aliquots of water or sediment were added to 50-ml serum bottles filled with 35-s-sulfate broth incubated for approximately 30 h. after incubation, the disintegration rate per milliliter of spent medium was measured, and the percentage of loss of activity resulting from bacterial sulfate reduction was dete ... | 1975 | 807162 |

| culture and identification of desulfovibrio spp. from corals infected by black band disease on dominican and florida keys reefs. | black band disease (bbd) of corals is characterized as a pathogenic microbial consortium composed of a wide variety of microorganisms. together, many of these microorganisms contribute to an active sulfur cycle that produces anoxia and high levels of sulfide adjacent to the coral surface, conditions that are lethal to coral tissue. sulfate-reducing bacteria, as sulfide producers, are an important component of the sulfur cycle and the black band community. previous molecular survey studies have s ... | 2006 | 16703774 |
| comparison of the anaerobic microbiota of deep-water geodia spp. and sandy sediments in the straits of florida. | marine sediments and sponges may show steep variations in redox potential, providing niches for both aerobic and anaerobic microorganisms. geodia spp. and sediment specimens from the straits of florida were fixed using paraformaldehyde and 95% ethanol (v/v) for fluorescence in situ hybridization (fish). in addition, homogenates of sponge and sediment samples were incubated anaerobically on various cysteine supplemented agars. fish analysis showed a prominent similarity of microbiota in sediments ... | 2010 | 20090787 |
