The effect was studied of trisodium citrate addition on the growth and formation of diacetyl and acetoin by Lactococcus lactis ssp. lactis CNRZ 483 in a whey-based medium under an oxygen pressure of 2...
Intracellular peptidases were extracted from the cell lysate of Lactococcus lactis ssp. cremoris SK11 that had been grown in milk. Peptidase activities were determined using 12 synthetic derivatives o...
This study illustrated the effect of controlled oxygenation on diacetyl production by citrate-utilizing Lactococcus lactis ssp. lactis CNRZ 483. Effects of soluble oxygen concentrations at 21 and 50% ...
Commercial cheese products were surveyed for ß-casomorphin peptides. Two extraction methods were compared: 1) water and 2) chloroform and methanol. Peptide profiles were determined using reverse...
A caseolytic proteinase with low activation energy was purified to homogeneity by conventional chromatographic techniques from Lactococcus lactis ssp. lactis IAM 1198. The molecular weight of the enzy...
When grown in skim milk, Lacrococcus lactis ssp. lactis biovar. diacetylactis D1 accumulated -acetolactic acid at 1.7 mM because of the absence of -acetolactate decarboxylase. The -acetolactic acid pr...
Transconjugants of Lactococcus lactis ssp. lactis ML3 that acquire the ability to utilize lactose often exhibit self-aggregation and become able to transfer the ability to utilize lactose at frequenci...
A substance, active as a B-cell mitogen, was isolated from the slime products produced by Lactococcus lactis ssp. cremoris KVS20. The mitogenic substance was prepared by anion-exchange chromatography ...
