Microbial succession during a composting process as evaluated by denaturing gradient gel electrophoresis analysis
The DGGE method is useful to reveal microbial succession during a composting process and bacterial populations were more complex than in previous phases and the phylogenetic positions of those populations were relatively distant from strains so far in the DNA database.
Distribution of putative denitrifying methane oxidizing bacteria in sediment of a freshwater lake, Lake Biwa.
The distribution of putative denitrifying methane-oxidizing bacteria related to "M. oxyfera" was investigated in a freshwater lake, and it was suggested that the upper layer of the profundal sediments is the main habitat for denItrifying methanotrophs.
Degradative capacities and 16S rRNA-targeted whole-cell hybridization of sulfate-reducing bacteria in an anaerobic enrichment culture utilizing alkylbenzenes from crude oil
The results show that completely oxidizing, alkylbenzene-utilizing sulfate-reducing bacteria rather than Desulfovibrio species have to be considered in attempts to understand the microbiology of sulfide production in oil wells, tanks, and pipelines when no electron donors other than the indigenous oil constituents are available.
Sulfate-Reducing Bacteria and Their Activities in Cyanobacterial Mats of Solar Lake (Sinai, Egypt)
ABSTRACT The sulfate-reducing bacteria within the surface layer of the hypersaline cyanobacterial mat of Solar Lake (Sinai, Egypt) were investigated with combined microbiological, molecular, and

After the addition of hydrogen into in vitro gray streamers with in situ spring water, sulfide production markedly occurred in the presence of ambient sulfate at 66 degrees C, suggesting that in situ sulfide is partly produced by Thermodesulfobacteria-like sulfate-reducing bacteria in the streamers.
Sulfuritalea hydrogenivorans gen. nov., sp. nov., a facultative autotroph isolated from a freshwater lake.
On the basis of its phylogenetic and phenotypic properties, strain sk43H(T) represents a novel species of a new genus, for which the name Sulfuritalea hydrogenivorans gen. nov., sp.
Molecular Characterization of Community Structures and Sulfur Metabolism within Microbial Streamers in Japanese Hot Springs
Community structures of submerged microbial slime streamers in sulfide-containing hot springs at Nakabusa and Yumata, Japan, were investigated by molecular analysis based on the 16S rRNA gene, suggesting that there is in situ sulfide production by as-yet-uncultivated Thermodesulfobacteria-like microbes.
Microbial Community Structure, Pigment Composition, and Nitrogen Source of Red Snow in Antarctica
Based on an estimation of trophic level, it was suggested that primary nitrogen sources of the red snow were supplied from fecal pellet of seabirds including a marine top predator of Antarctica.
Sulfur-metabolizing bacterial populations in microbial mats of the Nakabusa hot spring, Japan.
At the Nakabusa hot spring, Japan, dense olive-green microbial mats develop in regions where the slightly alkaline, sulfidic effluent has cooled to 65°C. The microbial community of such mats was
