Abstract
Summary: Redox potential changes at 30°C in anaerobic reconstituted skim-milk cultures ofStreptococcus cremorisAM1and AM2andStreptococcus lactisML8have been investigated in batch cultures and continuous cultures maintained at constant pH by the addition of fresh medium.Str. lactisML8was more strongly reducing than eitherStr. cremorisAM1or AM2. The positiveEhvalues which can arise in dense continuous cultures of lactic streptococci are not likely to affect either the lactic acid formation or proteolytic activity of the resultant bacterial concentrate. An electrolytic reduction cell is described which allows variations in redox potential in cultures to be controlled simply and effectively.Keywords
