Summary: An anaerobic, hydrogenotrophic methane-producing archaeon, strain CANT, was isolated from a alkaline thermal spring in New Caledonia. It is alkaliphilic, thermotolerant and utilizes hydrogen and carbon dioxide for autotrophic growth. Phylogenetic analysis and physiological studies revealed that strain CANT represents a novel species, proposed as Methanobacterium alkalithermotolerans sp. nov.

Summary: A thermophilic methanogen was enriched in coculture from Washburn Hot Springs in Yellowstone National Park, grown on carbon dioxide and hydrogen, and subsequently sequenced. The reconstructed 1.65-Mb genome sequence for Methanothermobacter thermautotrophicus WHS contributes to our understanding of hydrogenotrophic, CO2-reducing methanogenesis in geothermal ecosystems.

Summary: A novel methylotrophic methanogen, Methanococcoides orientis sp. nov., was isolated from East China Sea sediment. The strain can utilize various methylated compounds for growth and methanogenesis, but cannot use H2/CO2 or acetate. It grows optimally at a temperature of 30-35 degrees C, pH of 7.0-7.5 and salinity of 1.0%-5.0% NaCl.

Summary: We isolated and analysed a thermophilic bacterium, strain DA-C8(T), from compost in Ishigaki Island, Japan, that can degrade xylan and other polysaccharides. The strain showed high xylan degradation ability under anaerobic growth conditions, with an optimum growth temperature of 55 degrees C and pH 9.0. Phylogenetic analysis revealed that strain DA-C8(T) belongs to the proposed novel genus Insulambacter gen. nov.

Summary: Two thermophilic strains, FJAT-2464(T) and FJAT-52740, isolated from sediment in Zhangjiang Estuary Mangrove National Nature Reserve, Fujian Province, China, were found to belong to the same genome species with 100% 16S rRNA gene sequence similarity. The strain FJAT-2464(T) showed similarities to other Neobacillus species and was identified as a novel species, Neobacillus sedimentimangrovi sp. nov., with unique characteristics.

Summary: Two thermophilic bacterial strains, FJAT-47801(T) and FJAT-47835, were isolated from the sediment collected from Zhangjiang Estuary Mangrove National Nature Reserve in Fujian Province, China. These strains belong to the genus Bacillus and show high similarity to Bacillus oleivorans. Based on their unique characteristics and phylogenetic analysis, a new species, Bacillus litorisediminis sp. nov., is proposed for strain FJAT-47801(T). The importance of this discovery lies in expanding our knowledge of microbial diversity and understanding the ecological roles of thermophilic bacteria in mangrove ecosystems.

Summary: Biological denitrification is an important process in the nitrogen biogeochemical cycle of terrestrial geothermal environments. This study isolated five thermophilic bacterial strains from hot spring sediments in Tibet, China, and identified them as novel species of the genus Thermus. The strains showed potential function in nitrogen metabolism based on the presence of denitrification genes in their genomes.

Summary: A novel anaerobic bacterium SYSU GA19001T, which belongs to the genus Clostridium, was isolated from a hot spring sediment sample. It showed the highest sequence similarity to Clostridium swellfunianum CICC 10730T (96.63%) and Clostridium prolinivorans PYR-10T (96.11%). The strain SYSU GA19001T is a Gram-stain positive, spore-forming, rod-shaped bacterium, and it can grow at pH 5.0-9.0 (optimum, pH 7.0), 37-55°C (optimum, 45°C), and in NaCl concentrations of 0-2.0% (optimum, 0%).

Summary: Ex-situ biomethanation is an emerging technology for converting CO2 and H-2 into biomethane. This study investigated the influence of different H-2:CO2 ratios on the conversion of exogenous and endogenous CO2 to biomethane. Results showed that the reactor achieved a high CH4 content of up to 98% at a 6:1 H-2:CO2 ratio.

Summary: Five novel halophilic archaeal strains were isolated from coastal saline sediments and sea salt in China. They demonstrated typical morphology and growth characteristics and showed high similarities with existing species. However, based on genetic and phylogenetic analyses, it is confirmed that these strains represent five new species. This is the first report of a novel haloarchaeon isolated from a marine intertidal zone.

They were closely related to Caldovatus sediminis based on the phylogenetic analysis and were described as a new species, Caldovatus aquaticus sp. nov. Strain SYSU G05006T had a genome size of 3.87 Mbp and showed optimal growth at 55 degrees C and pH 6.0.
