Phototrophic Growth and Accumulation of Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) by Purple Nonsulfur Bacterium Rhodopseudomonas palustris SP5212

Table 2

Effect of cosupplementation of hydroxybutyrate and valerate on growth and PHA accumulation by R. palustris SP5212.

Hydroxybuty-rate : Valerate	Growth, g/L	PHA,; % CDW	Composition of PHA, Mol%
			3HB	3HV
1 : 3	0.49	26.77	57.66	42.33
1 : 1	0.52	46.26	66.61	33.38
3 : 1	0.66	54.71	48.47	51.52

The isolate was grown in acetate medium supplemented with hydroxybutyrate and valerate in different proportion, and other conditions are the same as mentioned under Table 1.
