Commensalistic Interaction Between Lactobacillus acidophilus and Propionibacterium shermanii

Effect of Aeration on Organic Acid Production by Propionibacterium shermanii

Propionibacteria have been reported as being oxygen sensitive bacteria. Nevertheless, in this work, we intend to show that Propionibacterium shermanii CDB 10014 is able to grow even at high volumetric oxygen transfer coefficients (KLa). Similar final cell concentrations were achieved in experiments at different KLa values, with increasing cell yield from 0.08 g/g cells in anaerobic con­ ditions...

Effects of orally administered viable Lactobacillus rhamnosus GG and Propionibacterium freudenreichii subsp. shermanii JS on mouse lymphocyte proliferation.

Immunomodulation by probiotics is a subject of growing interest, but the knowledge of dose response and time profile relationships is minimal. In this study we examined the effects of Lactobacillus rhamnosus GG (LGG) and Propionibacterium freudenreichii subsp. shermanii JS (PJS) on the proliferative activity of murine lymphocytes ex vivo. Dose dependency was assessed by treating animals peroral...

Interactions between Lactobacillus acidophilus strains and the starter cultures Lactobacillus bulgaricus and Streptococcus the

It has been observed that Lactobacillus acidophilus has poor survivability in fermented goats’ milk. In this study, interactions between L. acidophilus and starter cultures during goats’ milk fermentation were investigated using three strains of L. acidophilus: ATCC-11975, LA-5 and NCFM, and the starter cultures (Lactobacillus delbrueckii subsp. bulgaricus (LB350) and Streptococcus thermophilus...

Lactobacillus acidophilus, and Lactobacillus plantarum occur naturally in the human

Characterization of Rhamnosidases from Lactobacillus plantarum and Lactobacillus acidophilus.

Lactobacilli are known to use plant materials as a food source. Many such materials are rich in rhamnose-containing polyphenols, and thus it can be anticipated that lactobacilli will contain rhamnosidases. Therefore, genome sequences of food-grade lactobacilli were screened for putative rhamnosidases. In the genome of Lactobacillus plantarum, two putative rhamnosidase genes (ram1(Lp) and ram2(L...
