Halomonas litopenaei sp. nov., a moderately halophilic, exopolysaccharide-producing bacterium isolated from a shrimp hatchery.

Two Gram-stain negative, moderately halophilic, exopolysaccharide-producing bacteria, designated strains SYSU ZJ2214 and SYSU XM8, were isolated from rearing water and larvae from shrimp hatcheries, respectively. Cells of the strains were aerobic, motile and short-rod-shaped. They grew at NaCl concentrations of 0.
