Potentials of Exopolysaccharides from Lactic Acid Bacteria

Abstract

Recent research in the area of importance of microbes has revealed the immense industrial potential of exopolysaccharides and their derivative oligosaccharides from lactic acid bacteria. However, due to lack of adequate technological knowledge, the exopolysaccharides have remained largely under exploited. In the present review, the enormous potentials of different types of exopolysaccharides from lactic acid bacteria are described. This also summarizes the recent advances in the applications of exopolysaccharides, certain problems associated with their commercial production and the remedies.

Scale up of dextran production from a mutant of Pediococcus pentosaceus (SPAm) using optimized medium in a bioreactor

“…(C 6 H 10 O 5 )n are a class of homopolysaccharides produced by the lactic acid bacteria belonging to the genera Lactobacillus, Leuconostoc, Streptococcus and Weissella (Katina et al, 2009;Patel et al, 2011). Dextrans consist of D-glucose units polymerized predominantly in α-(1→6) linkage (Padmanabhan et al, 2003) and α-(1→2), α-(1→3), α-(1→4) glycosidic linked branches .…”

Dextrans have enormous industrial applications due to their nonionic, inert, stable, porous, gelling and pseudoplastic attributes (Patel et al, 2011). These are used as food syrup stabilizers, matrix of chromatography columns, blood plasma substitutes, antithrombogenic agents, treatment for iron deficiency anaemia, drug carriers (Purama and Goyal, 2005;Patel et al, 2011).…”

Dextrans have also been reported to arrest the replication of human immunodeficiency virus (HIV-1), the causative agent of the dreaded AIDS (Baba et al, 1990;Ko et al, 1991).…”

“…Dextrans act as protective coating against oxidation for metal nanoparticles (Bautista et al, 2005) and shield against biofouling in biomaterials (Sengupta et al, 2006).) Use of dextrans have ramified into paper, metal-plating processes and enhanced oil recovery (Patel et al, 2011). Dextrans from various microbial sources have been studied and characterized to evaluate their industrial potentials (Purama et al, 2009;Majumder and Goyal, 2009;Patel et al, 2010).…”

Efficient Production of Lactic Acid from Sweet Sorghum Juice by a Newly Isolated Lactobacillus salivarius CGMCC 7.75

“…Lactic acid (LA) plays an important role in our daily life in that it can be used as an acidulant, flavor enhancer, and preservative in the food [1][2][3][4]. In recent decades, lactic acid bacteria (LAB) have been traditionally used for LA production and become the predominant approach for industrial LA production.…”
