Comparison and optimization of conjugated linoleic acid production by Lactobacillus plantarum and Lactobacillus plantarum subsp. plantarum

Production and Partial Characterization of a Glycoprotein Bioemulsifier Produced by Lactobacillus plantarum subsp. plantarum PTCC 1896

Given the growing interest in the production of new and low cost bioemulsifiers, the rice and wheat bran and straw were investigated in this study for the production of bioemulsifier by Lactobacillus plantarum subsp. plantarum PTCC 1896 (probiotic). The strain produced bioemulsifier only in the rice bran hydrolysate medium. The bioemulsifier amount reached around 0.7 g L for 72 hours of ferment...

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...

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...

Ricinoleic acid and castor oil as substrates for conjugated linoleic acid production by washed cells of Lactobacillus plantarum.

Ricinoleic acid (12-hydroxy-cis-9-octadecaenoic acid) was an effective substrate for conjugated linoleic acid (CLA) production by washed cells of Lactobacillus plantarum AKU 1009a. The CLA produced was a mixture of cis-9,trans-11- and trans-9,trans-11-octadecadienoic acids. Addition of alpha-linolenic acid to the culture medium increased the CLA productivity of the washed cells. In the presence...
