CONTINUOUS PROCESS FOR MICROBIAL DEGRADATION OF TOBACCO CONSTITUENTS CONTAINING NITRATES

摘要

Microbial degradation of nitrates in a tobacco extract takes place in a first fermenter under exponential growth conditions of the micro-organisms employed and subsequently in a second fermenter under stationary growth conditions of the degrading micro-organisms. In the first fermenter, carbohydrates are added, while in the second fermenter the depot carbohydrates which the micro-organisms have stored in the first fermenter are utilized.
