Aeromonas punctataFA440 (formerly named Aeromonas caviae FA440) and Aeromonas hydrophila 4AK4 couldsynthesize poly(3-hydroxy--butyrate-co-3-hydroxyhexanoate) (PHBHHx) from lauric acid(dodeconoate), one of the member of polyhydroxyalkanoate (PHA).

• 豚鼠气单胞菌(Aeromonaspunctata FA440,原来命名为Aeromonas caviae FA440)与嗜水气单胞菌(Aeromonashydrophila 4AK4)都能利用月桂酸(十二碳脂肪酸)合成3-羟基丁酸(3HB)和3-羟基己酸(3HHx)的共聚物(PHBHHx)。
