Growth and PHB biosynthesis properties of R. eutropha H16. The cells were cultivated in a mineral salts medium containing 0.2% NH4Cl and 2.0% (w/v) fructose ( A ) or 0.1% x5 (w/v) sodium octanoate ( B ). Allows indicate the time point at which samples were withdrawn. F16, exponential growth phase on fructose; F26, PHA production phase on fructose; F36, stationary phase on fructose; O26, PHA production phase on octanoate. DCM, dry cell mass; RCM, residual cell mass. (This figure is the same as that in Ref. ).
