Substrate limited growth

Web10 Jan 2014 · At batch phase exponential growth and subsequent switch to substrate limited fed-batch, similar growth activity was observed at homogeneous and oscillating process conditions. From the very similar growth curve data a good reproducibility of the experiments can be deduced. Net respiration activity changed only slightly at batch … WebData of growth efficiency, respiration and growth rate of pelagic marine and freshwater bacteria under organic substrate limitation, and non-organic carbon limitation were taken from the published literature. The Pirt model (1975) was developed mainly from data obtained with continuous cultures, which by definition are substrate limited.
