Abstract

The extracellular polymeric substances (EPS) extracted from Pseudomonas putida ATCC 11172 at different carbon concentration, where Luria broth used as medium growth with and without addition of 0.5% w/v (LBG 0.5%) and 1.0% w/v (LBG 1%) glucose. The Bound EPS were extracted by ethylene diamine tetra acetic acid (EDTA) methods and precipitated by cold ethanol 3:1; while free EPS extracted only by precipitate by cold ethanol 3:1. The study shows the clear effect of carbon concentration on the production of EPS. The amount of free EPS found 120.39±2.20, 111.16±1.75 and 100.38±2.0 mg g^-1 dry cell for LB, LBG 0.5 and LBG 1 respectively. Where the yield of bound EPS shows fewer amounts from free EPS, the amount of bound EPS was 29.22±1.40, 21.18±0.90 and 17.10±1.10 mg g^-1 dry cell for LB, LBG 0.5 and LBG 1 respectively.
