Energy balances enhancement factors

Therefore, further increases in reaction rate do not result in increases in absorption rate and the enhancement factor remains constant. This asymptote reflects the balance between the tendency for increases in to steepen the interfacial concentration gradient, but at the same time to increase the temperature and thereby decrease the available driving force for the absorption. Eqn (29) therefore gives a measure of the magnitude of interfacial temperature achieved by the release of heat of reaction. This measure of interfacial temperature is conservative since in Eqn (29) M refers to the case where the activation energy is zero and the reaction rate is not accelerated by the rise in interfacial temperature. 

Exopolysaccharide production ntay be improved by tiie provision of various organic con xments, otiier Aan the main carbon and energy source. These can improve growth of the production organism (growth factors) and/or directly enhance the synthesis of exopolysaccharide. Additions that improve polymer yield include tricarboxylic add (TCA) cyde intermediates, which are thou t to improve metabolic balance between carbon flow frcnn carbohydrate substrate through the catabolic pathwaj arul oxidation through the TCA cyde.
