ABSTRACT:
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.
