| humic substance-mediated fe(iii) reduction by a fermenting bacillus strain from the alkaline gut of a humus-feeding scarab beetle larva. | humus-feeding macroinvertebrates play an important role in the transformation of soil organic matter. their diet contains significant amounts of redox-active components such as iron minerals and humic substances. in soil-feeding termites, acid-soluble fe(iii) and humic acids are almost completely reduced during gut passage. here, we show that the reduction of fe(iii) and humic acids takes place also in the alkaline guts of scarab beetle larvae. sterilized gut homogenates of pachnoda ephippiata n ... | 2012 | 22525666 |
| bacillus stamsii sp. nov., a facultatively anaerobic sugar degrader that is numerically dominant in freshwater lake sediment. | a novel type of anaerobic bacteria was previously isolated from profundal lake sediment by direct dilution of the sediment in mineral agar medium containing glucose and a background lawn of methanospirillum hungatei as a syntrophic partner. the isolated bacteria grouped with aerobic bacillus spp. according to their 16s rrna gene sequence, and the most closely related species is bacillus thioparans. fermentative growth of the novel strain with glucose was possible only in the presence of syntroph ... | 2015 | 26194116 |
| taxonomic description and genome sequence of bacillus campisalis sp. nov., a member of the genus bacillus isolated from a solar saltern. | the taxonomic position of a gram-stain positive bacterium isolated from a solar saltern sample collected from kanyakumari, coastal region of the bay of bengal, india, was analysed by using a polyphasic approach. the isolated strain, designated sa2-6t, had phenotypic characteristics that matched those of the genus bacillus. the 16s rrna gene sequence (1493 bases) of the novel strain was compared with those of previously studied bacillus type strains and confirmed that the strain belongs to the ge ... | 2015 | 26296567 |
| isolation and characterization of bacillus thioparus sp. nov., chemolithoautotrophic, thiosulfate-oxidizing bacterium. | a novel bacterium, strain bmp-1(t), was isolated from a continuous wastewater treatment culture system operating with a bacterial consortium. cells of the isolate were gram-variable, aerobic, moderately halotolerant, motile and endospore-forming rods. strain bmp-1(t) grew chemolithoautotrophically by oxidation of thiosulfate to sulfate with a growth yield of 1.07 g protein mol(-1) of thiosulfate consumed. dna g+c content was 43.8 mol%. its cell wall had peptidoglycan based on m-diaminopimelic ac ... | 2007 | 17451444 |
