• Polyhydroxyalkanoate
• Psychrotrophic
• Exopolysaccharide
• Pseudoaltermonas

A deep-sea psychrotrophic bacterium Pseudoaltermonas sp. SM9913, isolated from abyssalbenthic sediments in Bohai Sea, was found to be able to synthesize polyhydroxyalkanoate (PHA) polymer consisting of mainly 3-hydroxydecanoate and 3-hydroxydodecanoate. PHA accumulation in Pseudoaltermonas sp. SM9913 was confirmed by transmission electron microscope, Nile red dye and gas chromatography/mass spectral. The PHA content was determined as high as 2-3% of cell dry weight when the strain was grown in a sea water-based liquid medium. The relationship between PHA and exopolysaccharide accumulation in this strain was discussed.
