(Submitter supplied) Lactobacillus helveticus is a rod-shaped lactic acid bacterium that is widely used in the manufacture of fermented dairy foods and for production of bioactive peptides from milk proteins. Although L. helveticus is commonly associated with milk environments, phylogenetic studies show it is closely related to an intestinal species, Lactobacillus acidophilus, which has been shown to impart probiotic health benefits to humans. more...

(Submitter supplied) The response to bile of Lactobacillus casei BL23 and its derivative strain TC01 was investigated. TC01 strain carries a complete deletion of gene LCABL_02080 which encodes a two component signal transduction response regulator.

(Submitter supplied) This study investigated features of the acid tolerance response (ATR) in Lactobacillus casei ATCC 334. To optimize ATR induction, cells were acid adapted for 10 or 20 min at different pH values (range, 3.0 to 5.0) and then acid challenged at pH 2.0. Adaptation over a broad range of pHs improved acid tolerance, but the highest survival was noted in cells acid adapted for 10 or 20 min at pH 4.5. Analysis of cytoplasmic membrane fatty acids (CMFAs) in acid-adapted cells showed that they had significantly (P < 0.05) higher total percentages of saturated and cyclopropane fatty acids than did control cells. more...

(Submitter supplied) Nylon membrane (11 x 9 cm) with spotted PCR products up to 2.5 Kb, representing the full-length genes or a 2.5 kb internal fragment for those genes exceeding 2.5 kb for 2390 L.casei genes. Protocol: Each selected ORF was amplified with specific primers from genomic DNA of Lactobacillus casei ATCC 334. As a general rule, the primers were selected to amplify the complete coding region excepting ORFs exceeding 2.5 kb for which a 2.5 kb internal fragment was amplified. more...

(Submitter supplied) The DNA is printed, spotted, or actually synthesized directly onto the support. The whole process is based on hybridization probing, a technique that uses fluorescently labeled nucleic acid molecules as "mobile probes" to identify complementary molecules, sequences that are able to base-pair with one another.
