Evaluation of Factors Affecting Polyhydroxyalkanoates Production by Comamonas sp. EB172 Using Central Composite Design [PDF]
, 2012 Aims: Statistical approach, central composite design (CCD) was used to investigate the complex interaction among temperature (25-37 °C), initial medium pH (5-9), inoculum size (4-10 % (v/v)), concentration of (NH4)2SO4 (0-1 g/L) and concentration of ...

Sporulation of Myxococcus xanthus in liquid shake flask cultures [PDF]
Journal of Bacteriology, 1989 When suspended in a liquid starvation medium, exponentially growing Myxococcus xanthus sporulated within 3 days. These myxospores were similar to spores developed within fruiting bodies, as determined by electron microscopy and the production of spore-specific protein S.

Intelligent modelling of bioprocesses: A comparison of structured and unstructured approaches [PDF]
, 2004 This contribution moves in the direction of answering some general questions about the most effective and useful ways of modelling bioprocesses. We investigate the characteristics of models that are good at extrapolating.
