| Abstract: | Summary The production of ethyl valerate by aqueous suspensions of whole cells of Pseudomonas fragi was followed over 8 h after the addition of ethanol and valeric acid. Initial quantity of esters formed ranged from 10 to 160  moles/100 ml under the following conditions: pH 8–9, 8–12°C, 5% (w/v) cell concentration, 0.01–0.05M valeric acid and 0.02–0.1M ethanol. |
