Article Abstract:
Lactobacillus acidophilus commonly inhabits the intestinal tract of both man and animal. The S-layer of Lactobacillus crispatus JCM 5810 of A2 strain acts as specific bacterial adhesin and initiates bacterial adhesion to the mammalian extracellular matrix (ECM), thereby providing direct evidence that normal intestinal bacterial flora can adhere to the subintestinal ECM. S layers commonly occur in lactic acid bacteria. JCM 5810 of the S-layer has high affinity towards I and IV collagen and exhibits functional heterogeneity.

Article Abstract:
The main fatty acids present in ten analyzed strains of lactic acid bacteria are palmitic, cis-vaccenic and lactobacillic acid. Most of the Lactobacillus and Lactococcus strains are unable to produce oleic acid. Some strains do not synthesize lactobacillic acid, though all the strains produce dihydrosterculic acid. Lactobacillic acid constitutes 21 to 31% of the total fatty acid concentration of Lactobacillus fermentum and L. buchneri.

Article Abstract:
Response surface methodology (RSM) is effective in developing, evaluating and optimizing the conditions for Lactobacillus casei culture. This is a regression model that uses third- and fourth-order polynomials. A central composite experimental design takes care of treatment allocation. The model predicts nutrient composition and proportion, incubation temperature, and effect between temperature and nutrient.
