Fermentation Reactors Questions

• Two continuous bioreactors containing the same organisms, fed with the same feed at the same dilution rate were compared. Reactor 1 started with an initial concentration of glucose of 10 g.l-1, while reactor 2 contained 0.1 g.l-1 of glucose at the start of the process then at steady state
• In a glucose-yeast extract medium, Lactococcus lactis has a maximum specific growth rate (um) of 1.23 h-1. What would be the specific growth rate of this organism at steady state in a 4 litre reactor being fed at 2 litres per hour?
• The toxicity of organic acids to cells
• A microorganism which is subjected to the Crabtree effect is most likely to
• Production of organic acids in batch culture is generally growth associated phase followed by non-growth associated production. The probable reason for this is that
• In an activated sludge process, the biomass is recycled to
• Continuous culture has an advantage over to a batch cultures as
• Yeast is typically produced in fed batch reactors because
• Monoclonal antibodies are typically produced in fed batch reactors because
