The influence of different extracts on the acid production of two strains of Streptococcus cremoris and two of Betacoccus cremoris isolated from Kingston cheese has been studied.The enriching entity has no effect on acid production by Streptococci in sugar broth. Enrichment with yeast or alfalfa extract causes not only a marked increase in the acid production by Betacocci, but also a definite stimulating effect on the rate of acid production.Enriching milk with yeast or alfalfa extract has a marked stimulating effect on the vital activity of the Betacocci and of Streptococcus EMB1173, but is without influence on Streptococcus EMB1195. The response of culture EMB1173 is immediate and direct, but in the case of cultures EMB2168 and EMB2173 the action of the enriching entity is cumulative in its effect. Alfalfa extract would appear to provide, in the case of Betacoccus EMB2173, a stimulating influence not to be found in yeast extract.The influence of other forage crop enrichments on rate of acid production has also been studied. The factor or factors present in alfalfa and shown to exert a stimulating influence on the vital activity of the organisms are to be found to some extent in all forage crops investigated.

The abilities of type cultures of lactic acid bacteria to reduce five O/R indicators in plain milk and yeast dextrose milk have been described and the factors influencing their behaviour in this respect discussed. Methylene blue, litmus and safranine appear to be of some diagnostic value for the differentiation of types. There is a marked correlation between rapidity of growth in milk, ability to reduce O/R dyes and the proportion of by-products. This relationship holds not only for the different groups and types, but also for variations in behaviour observed in species kept under laboratory observation. It is suggested that rate of growth is fundamentally related to the amount of by-products and hence presumably to flavour-producing substances such as diacety and acetic acid. Thus in cheese-ripening enforced slowness of growth may be as important as the presence of specific types.
