A novel thermophilic, anaerobic, strictly chemoorganoheterotrophic bacterium, designated as AM1114(T), was isolated from a deep-sea hydrothermal vent sample from the East-Pacific Rise (EPR 13degrees N). The cells were long (3-10 mum) rods, motile with peritrichous flagella, and exhibited a Gram-negative cell wall ultrastructure. In the late stationary phase of growth, cells formed an ovoid, refractile, terminal endospore. They grew at 45-65 degreesC inclusive (optimum 55-60 degreesC; doubling time approx. 45 min), at pH 4.5-8.0 inclusive (optimum pH 7.5-8.0) and at sea salt concentrations of 20-60 g l(-1) inclusive (optimum 25-30 g l(-1)). Strain AM1114(T) was an obligately heterotrophic bacterium able to ferment a mixture of 20 amino acids, complex...
