- Protamylasse, a Residual Compound of Industrial Starch Production, Provides a Suitable Medium for Large-Scale Cyanophycin Production

FIG. 1. Effect of protamylasse concentration on growth and CGP accumulation in E. coli DH1(pMa/c5-914::cphA₆₈₀₃). Experiments were done in 250-ml Erlenmeyer flasks, each containing 100 ml medium with the indicated concentration of protamylasse and 100 µg ampicillin per ml. The flasks were inoculated from a preculture previously grown at 30°C. CGP biosynthesis was induced by incubating the cultures at 37°C. After an incubation period of 44 h, cells were harvested and analyzed for CGP content () and cell density () as described in Materials and Methods. The data shown represent mean values and standard deviations of three independent cultivation experiments.
