Summary
In an attempt to improve corrinoid production byM. barkeri strain Fusaro, a repeated fed-batch culture coupled with a membrane module on methanol-acetate medium was used. Productivity of 22 mg-corrinoid/1. day was obtained during 626 h cultivation with corrinoid and cell mass concentration of 95 mg/l and 25.9 g-dry cell/l, respectively. The minimum value for membrane flux permeation was 18 liter/m2. h for cell mass concentration between 25.9 to 31.0 g-dry cell/l. with rejection of 100 %.
