Fig. 1From: The expression of the acarbose biosynthesis gene cluster in Actinoplanes sp. SE50/110 is dependent on the growth phaseCharacterization of growth and acarbose production of Actinoplanes sp. SE50/110 in controlled fermenter conditions. Different growth phases (lag, growth, transition and stationary phase) were indicated by vertical dashed lines. a Cell dry weight (black boxes) and acarbose concentration (grey circles) over the cultivation course. Plotted are the means and standard deviations of three biological replicates, each of which were measured in three technical replicates. b Specific product formation rates (qAcarbose) defined as produced acarbose normalized on the mean cell dry weight and cultivation time differenceBack to article page
