Comments P.95 left column top paragraph: "The factors that influence the yield of heterotrophic bacteria, when growing on a single carbon substrate in a mineral salts medium, and under conditions of substrate limitation, are of considerable importance. Previously, attempts have been made to correlate this yield value with the energy potentially available in the growth substrate [refs 1,2] and the total energy taken from the growth medium [ref 2]. A constant yield factor of 1.1 g biomass/g substrate carbon was reported for sugars, polyhydric alcohols and paraffins, but yields on carboxylic acids were considerably lower [primary source]. The lower yields observed on these more highly oxidized substrates were attributed, in part, to growth-inhibitory effects of the carboxylic acids, and a "correction factor" had to be applied [ref 4]."
