The Ability of Lactobacillus Plantarum to Produce Exopolysaccharides with Additional Nutrients

Exopolysaccharides (EPS) are polysaccharides secreted by microbes out of cells. EPS has potential in the pharmaceutical industry as a texture and rheological agent. EPS was produced by lactic acid bacteria such as Lactobacillus plantarum using a substrate that containing glucose. The purpose of the...

Description
Summary:Exopolysaccharides (EPS) are polysaccharides secreted by microbes out of cells. EPS has potential in the pharmaceutical industry as a texture and rheological agent. EPS was produced by lactic acid bacteria such as Lactobacillus plantarum using a substrate that containing glucose. The purpose of the study was to determine the ability of Lactobacillus plantarum to produce exopolysaccharides with the addition of nutrients, namely (NH 4 ) 2 HPO 4 and raspberry juice as a source of sugar. A fermentation process carried out the EPS production based on a growth curve for 15, 21, and 27 hours with nutrients and without adding nutrients. The additional sugar came from raspberries with concentrations of 25%, 30%, and 35%. EPS levels without the addition of (NH 4 ) 2 HPO 4 with a raspberry concentration of 35% at 15, 21, and 27 hours resulted in 2624, 3704, and 3928 mg/L. The results showed that EPS levels with the addition of (NH 4 ) 2 HPO 4 with a raspberry concentration of 35% at 15, 21, and 27 hours resulted in EPS levels of 3374, 4072, and 4792 mg/L.
