Production of acetic acid by a repeated batch culture with cell recycle ofAcetobacter aceti

Abstract

A comparison of volumetric production rates of acetic acid inAcetobacter aceti M23 was conducted for repeated batch (RB), cell-recycling repeated batch (CRB) and continuous (C) cultures. Best result was obtained with CRB culture. The magnification of productivity was 1.7 (to RB culture) and 3.3 (to C culture) for aiming final acetic acid concentration of 60 g/l and 42 g/l, respectively.
