Biosynthesis of exopolysaccharide by a Bacillus licheniformis strain isolated from ropy cider

Production and characterization of the exopolysaccharide produced by Paenibacillus jamilae grown on olive mill-waste waters

“…The production of two different polysaccharides in pure cultures has been observed for other organisms, for instance, Bacillus thermoantarcticus (Manca et al 1996) and Paecilomyces tenuipes (Xu et al 2006). Some exopolysaccharides produced by endospore forming rods belonging to the genus Bacillus have been reported (Kawai et al 1992;Manca et al 1996;Isobe et al 1997;Corsaro et al 1999;Larpin et al 2002), but thus far only two description about production of EPS by other species belonging to Paenibacillus has been published (Yoon et al 2002;Prado Acosta et al 2005). Thus, the present work provides useful information about this new source of biopolymers.…”

Studies of the Extracellular Glycocalyx of the Anaerobic Cellulolytic Bacterium Ruminococcus albus 7

“…Analysis of the extracellular polysaccharide recovered in this fashion revealed an abundance of Man and Xyl units, with much smaller amounts of Rha, Ara, and Gal. Among gram-positive bacteria, Man has been identified as a substantial component of only a few exopolysaccharides from strains in the Bacillus (23,26,43) and Propionibacterium (14) lineages. By contrast, the exopolysaccharides of the lactic acid bacteria Lactobacillus, Lactococcus, and Streptococcus, which have received considerable study due to their food and industrial use, contain primarily Gal, Glc, and Rha (13), and Gal has been reported to be the major monosaccharide associated with the cellulosome complex of the cellulolytic anaerobic bacterium Clostridium thermocellum (11).…”

Exopolysaccharide produced by Bacillus licheniformis strains isolated from Kimchi

“…From these results, it appears that the EPS KS-17 and EPS KS-20 consist of only the glucose monomer. Previously, it was reported that EPS synthesized by a B. licheniformis strain isolated from ropy cider was mainly composed of mannose (80.5%), glucose (6.5%) and other unknown components (13%) (Larpin et al, 2002), while EPS synthesized by B. licheniformis 8-37-0-1 isolated from soil was reported as fructose and glucose in a molar ratio of 33 1 (Liu et al, 2010). However, the EPS from isolated from our strains of B. licheniformis KS-17 and KS-20 showed only a single constituent glucose molecule, indicating that these must be different from those previously reported in B. licheniformis strains derived from other sources.…”
