Table 1 Cell growth and PHB production attained by H. boliviensis in shake flasks using different carbon sources. Samples were withdrawn after 30 h of cultivation. The experiments were performed in triplicate at a temperature of 35 °C and an agitation speed of 200 rpm; standard deviations of the mean values are shown in parentheses. Abbreviations refer to cell dry weight (CDW) and residual cell mass (RCM)
