Pseudomonas resinovorans produced poly-beta-hydroxyalkanoates (PHAs) when grown on hydrocarbons but not on glucose. In a chemostat culture, the PHA composition was beta-hydroxybutyrate (C4)-beta-hydroxyhexanoate (C6)-beta-hydroxyoctanoate (C8)-beta-hydroxydecanoate (C10) (1:15:75:9) on octanoate and C4-C6-C8-C10 (8:62:23:7) on hexanoic acid. Contrary to the reported behavior of Pseudomonas oleovorans, the PHA accumulation rate increased under ammonium limitation on octanoate.
树脂糖假单胞菌在以烃类为碳源生长时能产生聚-β-羟基脂肪酸酯(PHA),但以葡萄糖为碳源时则不能。在恒化器培养中,以辛酸为碳源时PHA的组成是β-羟基丁酸(C4)-β-羟基己酸(C6)-β-羟基辛酸(C8)-β-羟基癸酸(C10)(1:15:75:9),以己酸为碳源时PHA的组成是C4-C6-C8-C10(8:62:23:7)。与报道的食油假单胞菌的行为相反,在以辛酸为碳源且铵受限的情况下,PHA的积累速率增加。
