Lactobacillus plantarum ST202Ch and Lactobacillus plantarum ST216Ch – What are the Limitations for Application?

Pentose Fermentation by Lactobacillus Plantarum

Extracts of Lactobucillus plantarum derived from cells grown on Larabinose contain an active isomerase, which converts L-arabinose to Lribulose (1, 2), and a ribulokinase, which catalyzes the formation of L-ribulose &phosphate (3,4). Such extracts also catalyze the conversion of L-ribulose 5-phosphate to D-xylulose 5-phosphate, which has been shown to be the key intermediate in pentose fermenta...

Lactobacillus acidophilus, and Lactobacillus plantarum occur naturally in the human

Carotenoid production in Lactobacillus plantarum.

Eighteen strains of Lactobacillus plantarum from different origins were screened for carotenoid production, as many of them exhibited a deep yellow pigmentation when cultured as isolated colonies on MRS-agar plates. We found that most of them produced significative amounts of the yellow C(30) carotenoid 4,4'-diaponeurosporene in the range 1.8 to 54 mg/kg of dry cell weight. Although some of the...

Antibiotic Resistance in Lactobacillus reuteri and Lactobacillus plantarum

Lactic acid bacteria (LAB) may act as reservoirs of antibiotic resistance genes that can be transferred via the food chain or within the gastrointestinal tract to pathogenic bacteria. This thesis provides data required for assessing the potential risk of using antibiotic resistant strains of the LAB species Lactobacillus reuteri and Lactobacillus plantarum as food processing aids or probiotics....

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...
