PCT No. PCT/EP95/00752 Sec. 371 Date Oct. 29, 1996 Sec. 102(e) Date Oct. 29, 1996 PCT Filed Mar. 1, 1995 PCT Pub. No. WO95/23845 PCT Pub. Date Sep. 8, 1995An accelerated micro-organism culture method is for decomposing harmful substances. For this purpose, the cultivation, mutagenic treatment and stabilization of the micro-organisms are carried out simultaneously in a mutation fermenter containing a nutrient-rich basic medium (basic medium 1); selection is carried out in a selection fermenter containing a basic medium which is low in nutrients and is enriched with the harmful substance (basic medium 2); small amounts of biomass released from the nutrient-rich basic medium (basic medium 1) of the mutation fermenter are continuously removed from the mutation fermenter and transferred to the selection fermenter. Small amounts of biomass released from the basic medium which is low in nutrients (basic medium 2) of the selection fermenter are removed from the selection fermenter and transferred to the mutation fermenter. The entire process is carried out continuously in alternating selection and mutation phases, in the manner of a repeated cycle. The mutation fermenter and the selection fermenter are associated with computerized control circuits by means of which the fermentation parameters can be adjusted independently of one another in both fermenters. |
