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 condition of the micro-organisms employed and subsequently in a second fermenter under stationary conditions of life of the degrading micro-organisms. In the first fermenter, carbohydrates are added, whilst in the second fermenter the depot carbohydrates which the micro-organisms have stored in the first fermenter are utilised.
