TWO-PHASE FERMENTATION OF STAPHYLOCOCCUS INCREASES NITRATE REDUCTASE ACTIVITY

摘要

The present invention is related to the field of reddening of food products. In particular the present invention relates to a two-phase fermentation method for boosting the nitrate reductase activity of Staphylococcus strains with nitrate reductase activity comprising a first aerobic phase in the absence of nitrate and a second anaerobic or oxygen limited phase with continuous nitrate feeding and use of the Staphylococcus strains for reddening of meat products.
