Brachybacterium aquaticum

Brachybacterium aquaticum is a species of Gram positive, strictly aerobic, pale yellow-pigmented bacterium. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. It was first isolated from a seawater sample collected from the coastal region of Kovalam, India off the Indian Ocean. The name is derived from Latin aquaticum.
The optimum growth temperature for B. aquaticum is 30 °C, but can grow in the 20-37 °C range. The optimum pH is 8.0 and can grow in pH 7.0-11.0.
