Abstract
Optimal growth temperatures in citrate broth for 6 strains of L. cremoris varied from 24.degree. through 27.degree. C and averaged 26.degree. C. The average generation time at 26.degree. C was 3.2 h. Minimal and maximal growth temperatures were 14.degree.-17.degree. and 34.degree.-36.degree. C, respectively. Comparison of the data for L. cremoris to that previously obtained for Streptococcus cremoris suggests that 22-25.degree. C is the appropriate temperature range for propagating diary cultures containing lactic streptococci and L. cremoris. Molar growth yields and values for end products produced in citrate broth (with citrate and acetate omitted) were excessively high because energy was gained and end products were produced from constituents of the complex medium other than added glucose.
