A medium was developed for selectively enumerating bile-resistant lactobacilli by adding 0.15% oxgall to lactobacillus selective agar (BBL). Lactobacilli were not found in many products sold as sources of Lactobacillus acidophilus , whereas others co

Lactobacillus acidophilus exerted antagonistic actions on growth of Staphylococcus aureus , Salmonella typhimurium , enteropathogenic Escherichia coli , and Clostridium perfringens when grown with each in associative cultures. S. aureus and C. perfri

Concentrated starter cultures are now used routinely in many food fermentations. Recent literature concerning preparation and performance of such cultures is reviewed. Batch procedures are preferred over continuous culture procedures for preparing co

The inhibition of growth of Staphylococcus aureus by lactic streptococci in associative cultures in milk was not due to hydrogen peroxide produced by the streptococci. Dialyzed whey from the milk culture of lactic streptococci was more inhibitory tha

Concentrated cultures of Lactobacillus bulgaricus were prepared by resuspending cells grown in semisynthetic media in sterile 10% non-fat milk solids. The concentrated cultures were frozen in liquid nitrogen for 24 h. The cell suspensions exhibited d

Concentrated cultures of lactic streptococci varied with respect to survival at -17 C. Cells of each strain grown at pH 6.0 were more stable to freezing than were those grown statically. The lipid fraction of the cells from static cultures was import

Lactobacillus species normally found in the intestinal tract of humans varied in the ability to deconjugate bile acids, whereas laboratory strains of Lactobacillus acidophilus deconjugated both glycocholate and taurocholate. All isolates of L. acidop

Incubation of inoculated substrates of the Minitek system in anaerobic GasPak jars provided a method that produced results comparable to those of conventional tubed media for characterizing species of Lactobacillus. The use of sterile mineral oil to

A milk beverage was prepared by adding a commercially available concentrated culture of Lactobacillus acidophilus to pasteurized low-fat milk. The culture did not alter the flavor of the milk. Consumption of the milk by healthy adult men increased fa

Considerable variation was found among strains of Lactobacillus acidophilus isolated from the fecal flora of pigs with regard to the ability to grow well in the presence of bile and to assimilate cholesterol from a laboratory growth medium. The uptak
