Effects of carbohydrate source on physicochemical properties of the exopolysaccharide produced by Lactobacillus fermentum TDS030603 in a chemically defined medium

Physicochemical characterization of exopolysaccharides produced by Lactobacillus rhamnosus on various carbon sources

“…rhamnosus E/N can be divided into four groups: (I) high-molecular-weight-fraction EPS composed of one type of polymer (EPS-Glc), (II) high-and-low-molecularweight-fraction EPS composed of one type of polymer (EPS-Lac and EPS-Suc), (III) high-and-low-molecular-weight-fraction EPS composed of two types of polysaccharides (EPS-Gal), and (IV) high-molecular-weight-fraction EPS composed of two types of polysaccharides (EPS-Mal). Our results are in agreement with Fukuda et al (2010), who also observed different molecular mass distributions but did not observe any differences in monosaccharide composition in EPS fractions produced by Lb. fermentum on different carbohydrate sources.…”

“…This approach might not be applicable to all Lactobacilli strains. For example, the EPS composition of Lactobacillus sake strain 0-1 and Lactobacillus fermentum TDS030603 has been found to be independent of the type of carbon source used (Fukuda et al, 2010;Van Den Berg et al, 1995). In the present work, the structure of EPS synthesized by Lb.…”

OPTIMAL CONDITIONS FOR EXOPOLYSACCHARIDE PRODUCTION BY Lactobacillus plantarum T10

“…After 48 h incubation, the amount of EPS started to decrease. Our results were in agreement with the study of Fukuda et al [6]. In the MRS medium supplemented with 1 % glucose, galactose, or sucrose, the amount of EPS synthesized by L. fermentum TDS030603 was highest after 48 h incubation.…”

“…Many studies showed that the best carbon sources for EPS production of lactic acid bacteria are lactose, glucose, and saccharose. Furthermore, nitrogen sources also an important medium component determining the EPS yield [2,3,4,5,6,7].…”

Production and purification of a novel exopolysaccharide from lactic acid bacterium Streptococcus phocae PI80 and its functional characteristics activity in vitro

“…Lactis contains fructose and rhamnose as sugar unit, which were determined in TLC. In addition, two monomers such as glucose and galactose were identified in EPS from L. fermentum TDS030603 using TLC plate (Fukuda et al, 2009). Liu et al (2009) reported the EPS produced by Paenibacillus polymyxa EJS-3 was composed of mannose, fructose and glucose.…”
