A novel thermophilic, chemoheterotrophic, Gram-negative, multicellular filamentous bacterium, designated strain 110S(T), was isolated from an iron-rich coastal hydrothermal field in Japan. The isolate is facultatively aerobic and chemoheterotrophic. Phylogenetic analysis using 16S rRNA gene sequence nested strain 110S(T) in a novel class-level clon...
At deep-sea vent systems, hydrothermal emissions rich in reductive chemicals replace solar energy as fuels to support microbial carbon assimilation. Until recently, all the microbial components at vent systems have been assumed to be fostered by the primary production of chemolithoautotrophs; however, both the laboratory and on-site studies demonst...
Ardenticatena maritima strain 110S is a filamentous bacterium isolated from an iron-rich coastal hydrothermal field, and it is a unique isolate capable of dissimilatory iron or nitrate reduction among the members of the bacterial phylum Chloroflexi. Here, we report the ability of A. maritima strain 110S to utilize electrodes as a sole electron acce...
Due to unique genomic adaptations, Methanococcus maripaludis Mic1c10 is highly corrosive when in direct contact with Fe ⁰ . A critical adaptation involves increased glycosylation of an extracellular [NiFe]-hydrogenase, facilitating its anchoring to cell surface proteins. Corrosive strains adapt to the constructed environment via horizontal gene tra...
Methanogenesis is classically thought to be limited to strictly anoxic environments. While oxygenated oceans are a known methane source, it is argued that methanogenesis is driven by methylphosphonate-degrading bacteria or potentially is associated to zooplankton gut microbiomes rather than by methanogenic archaea. Here we show through in situ moni...
Due to unique genomic adaptations, Methanococcus maripaludis Mic1c10 exhibits severe corrosive behavior when in direct contact with Fe0. These adaptations are linked to attachment and effective growth on constructed surfaces. One such adaptation is that of a specific [NiFe]-hydrogenase that may anchor on the cell surface via glycosyl-glycosyl inter...
Here, we present the genome sequences of a strain of Streptococcus alactolyticus and two strains of Escherichia coli that were isolated from feces samples from domestic pigs in Denmark. The genome sequences contribute to a better understanding of the microbiological processes in the feces and manure of domestic pigs.

The present study investigated extracellular electron transfer (EET) of Pseudomonas stutzeri, a model organism for bacterial denitrification. Electrochemical cultivation of P. stutzeri in a lithotrophic medium with Fe2+ ions generated the clear cathodic current associated with denitrification reactions. The EET ability of P. stutzeri was greatly st...

In bioelectrochemical systems where the oxidative current is mediated by microorganisms, it remains unexplored as to whether low-potential substrates (e.g. formate) enable the anode to work at lower potentials. Due to implications to relevant engineering and natural systems, this study evaluated such possibility and underlying causes. The investiga...
Physicochemical characteristics and archaeal and bacterial community structures in an iron-rich coastal hydrothermal field, where the temperature of the most active hot spot reaches above 100 ー C, were investigated to obtain fundamental information on microbes inhabiting a coastal hydrothermal field. The environmental settings of the coastal hydrot...
The increasing number of genome sequences of archaea and bacteria show their adaptation to different environmental conditions
at the genomic level. Aeropyrum spp. are aerobic and hyperthermophilic archaea. Aeropyrum camini was isolated from a deep-sea hydrothermal vent, and Aeropyrum pernix was isolated from a coastal solfataric vent. To investigat...
A novel anaerobic, Fe(III)-reducing, hydrogenogenic, carboxydotrophic bacterium, designated strain Ug1(T), was isolated from a volcanic acidic hot spring in southern Kyushu Island, Japan. Cells of the isolate were rod-shaped (1.0-3.0 µm long) and motile due to peritrichous flagella. Strain Ug1(T) grew chemolithoautotrophically on CO (100% in the ga...
A novel thermophilic bacterium, strain KW1(T), was isolated from a coastal hydrothermal field on the Satsuma Peninsula, Kagoshima Prefecture, Japan. The variably Gram-stained cells were motile rods with flagella, did not form spores and proliferated at 52-78 degrees C (optimum, 70 degrees C), pH 5-8 (optimum, pH 7) and 0-4.5 % NaCl (optimum, 1.0 %)...
