| tepidibacter thalassicus gen. nov., sp. nov., a novel moderately thermophilic, anaerobic, fermentative bacterium from a deep-sea hydrothermal vent. | a moderately thermophilic, anaerobic, endospore-forming bacterium (strain sc 562t) was isolated from a hydrothermal vent chimney located at 13 degrees n on the east-pacific rise at a depth of 2650 m. cells of strain sc 562t were straight to slightly curved rods, which were 0.7-0.9 microm in diameter and 3.5-6.0 microm in length with peritrichous flagella. strain sc 562t formed round, refractile endospores in terminally swollen sporangia. the temperature range for growth was 33-60 degrees c, with ... | 2003 | 12892139 |
| tepidibacter formicigenes sp. nov., a novel spore-forming bacterium isolated from a mid-atlantic ridge hydrothermal vent. | a novel anaerobic, gram-positive, sporulating and strictly chemoorganoheterotrophic bacterium, designated strain dv1184(t), was isolated from a deep-sea hydrothermal vent sample from the mid-atlantic ridge. the cells were short, straight rods (4 micro m long and 0.8 micro m wide) and were motile with peritrichous flagella. they grew between 35 and 55 degrees c (optimum, 45 degrees c), between ph 5.0 and 8.0 (optimum, 6.0) and at 20-60 g sea salts l(-1) (optimum sea salts concentration, 30 g l(-1 ... | 2004 | 15023956 |
| abundance and diversity of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (hmx)-metabolizing bacteria in uxo-contaminated marine sediments. | octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (hmx) is a toxic explosive known to be resistant to biodegradation. in this study, we found that sediment collected from two unexploded ordnance (uxo) disposal sites (uxo-3, uxo-5) and one nearby reference site (midref) in hawaii contained anaerobic bacteria capable of removing hmx. two groups of hmx-removing bacteria were found in uxo-5: group i contained aerotolerant anaerobes and microaerophiles, and group ii contained facultative anaerobes. in ... | 2007 | 17381523 |
| characterization of technetium(vii) reduction by cell suspensions of thermophilic bacteria and archaea. | washed cell suspensions of the anaerobic hyperthermophilic archaea thermococcus pacificus and thermoproteus uzoniensis and the anaerobic thermophilic gram-positive bacteria thermoterrabacterium ferrireducens and tepidibacter thalassicus reduced technetium [(99)tc(vii)], supplied as soluble pertechnetate with molecular hydrogen as an electron donor, forming highly insoluble tc(iv)-containing grayish-black precipitate. apart from molecular hydrogen, t. ferrireducens reduced tc(vii) with lactate, g ... | 2007 | 17619187 |
| tepidibacter mesophilus sp. nov., a mesophilic fermentative anaerobe isolated from the soil polluted by crude oil, and emended description of the genus tepidibacter. | a mesophilic, aerotolerant, endospore-forming, fermentative bacterium designated strain b1(t) was isolated from the soil polluted by crude oil in karamay oil field, china. cells were gram-positive, rod-shaped with 1.1-1.6 µm in width, 2.3-4.7 µm in length, and were motile with peritrichous flagella.the temperature and ph ranges for growth were 10-40 °c and ph 6.0-8.9, respectively. optimal growth occurred at 28-32 °c and ph 7.3. the optimal concentrations of nacl and sea salts for growth were 0. ... | 2011 | 21335504 |
