Gopal, Pramod K., Crow, Vaughan L.
Loosely associated material (LAM) was isolated by gentle extraction procedures from the cell surface of Lactococcus lactis subsp. cremoris E8 and its phage-resistant variant strain 398. LAM from both...
Two 2,3-butanediol dehydrogenases (enzymes 1 and 2; molecular weight of each, 170,000) have been partially purified from Lactococcus lactis subsp. lactis (Streptococcus diacetylactis) D10 and shown...
Polysaccharide Production by Propionibacteria during Lactose Fermentation
The fermentation products from 10 strains of propionibacteria accounted for only 72% (average value) of the lactose carbon utilized. The balance of the carbon was accounted for by the production of a...
Five strains of Propionibacterium freudenreichii subsp. shermanii utilized the l-(+) isomer of lactate at a faster rate than they did the d-(−) isomer when grown with a mixture of lactate isomers...
More than 90% of the aspartate in a defined medium was metabolized after lactate exhaustion such that 3 mol of aspartate and 1 mol of propionate were converted to 3 mol of succinate, 3 mol of...
During lactate fermentation by Propionibacterium freudenreichii subsp. shermanii ATCC 9614, the only amino acid metabolized was aspartate. After lactate exhaustion, alanine was one of the two amino...
Propionibacterium freudenreichii subsp. shermanii metabolized 7 mol of aspartate to 6 mol of succinate, 4 mol of CO2, and 7 mol of ammonia. When lactate, sparged with 100% CO2, was fermented at pH...
Influence of the Lactose Plasmid on the Metabolism of Galactose by Streptococcus lactis
LeBlanc, Donald J., Crow, Vaughan L., Lee, Linda N., Garon, Claude F.
Streptococcus lactis strain DR1251 was capable of growth on lactose and galactose with generation times, at 30°C, of 42 and 52 min, respectively. Phosphoenolpyruvate-dependent phosphotransferase...
Selection of Galactose-Fermenting Streptococcus thermophilus in Lactose-Limited Chemostat Cultures
Thomas, Terence D., Crow, Vaughan L.
Stock cultures of Streptococcus thermophilus are essentially galactose negative (Gal−). Although both galactose 1-phosphate uridyl transferase and uridine-5-diphospho-glucose 4-epimerase are...
