Starch Hydrolysate

Ultrafiltration (UF) is considered as a promising alternative to the traditional clarification techniques in the sugar industries. In this work, a hollow fiber UF membrane (polyacrylonitrile, MWCO 100 kDa) was used for clarification of cassava starch hydrolysate. The influence of various operating parameters, such as transmembrane pressure (TMP), cross flow velocity and pH hydrolysate on the membrane fouling was assessed. The results showed that TMP higher than 1.0 bar was not effective to improve flux. Increasing cross flow velocity was virtually effective to reduce permeate flux decline. The steady state flux, Jssincreased significantly when pH of the feed was adjusted to alkaline condition; however, this resulted in dark brown clarified glucose syrup. Operating at natural pH of 4.5, the membrane selectivity was close to 100%. Evaluation of hydraulic resistance indicated that concentration polarization and pore blocking were beyond approximately 50 and 40% of the total filtration resistance, respectively. Moreover, scanning electron microscopy showed that extensive fouling layer was deposited on the membrane surface. Finally, the developed cleaning procedure could restore membrane performance approximately 45% of its initial performance.

Exopolysaccharide (EPS) production ability of Lactobacillus plantarumT10 was studied. The supplement of some sugars (lactose, saccharose, and glucose) gave the positive effects on EPS production of L. plantarum T10, in which the addition of lactose 4 % resulted in the most efficiency for EPS yield (274.83 μg/mL). The addition of 0.4 % of yeast extract into culture medium with 4 % lactose provided the highest EPS yields compared to other nitrogen sources (peptone, beef extract), which were 378.32 mg/mL. The optimal conditions for EPS production of L. plantarum T10 in MRS broth with 4 % of lactose and 0.4 % yeast extract supplement were also studied. The results indicated that the highest EPS yield (417.11 mg/L) was obtained in the conditions of 106 CFU/ml initial cell density, temperature of 35 oC, pH 5.5 and 48 h incubation.
