PROCESS FOR DISSIMILATORY DENITRIFICATION OF TOBACCO MATERIALS

摘要

An improved process for the reduction of the nitrate content of tobacco materials via dissimilatory denitrification is disclosed wherein more rapid reduction of nitrate to nitrogen gas is effected by utilizing a vacuum during incubation. The process comprises inoculating nitrate-containing tobacco material with a microorganism capable of dissimilatory denitrification and thereafter incubating the tobacco material under conditions whereby the nitrate is reduced to nitrogen gas via dissimilatory denitrification while applying a vacuum.
