THE BIOELECTRICITY OF TOFU WHEY IN MICROBIAL FUEL CELL SYSTEM WITH LACTOBACILLUS BULGARICUS
ABSTRACT: Tofu whey is a
byproduct of the manufacturing process tofu which containing the remains of
protein, fat, carbohydrates and water-soluble substances that do not
agglomerate. This study aim was to assess the potential of tofu whey as a
substrate in the MFC system and to evaluate the effect of agitation speed to
the potential difference generated in the MFC system using Lactobacillus
bulgaricus. The potential difference in the variation of the substrate was
measured against tofu whey, glucose and lactose. The potential difference with
agitation speed variation was carried out at speed of 30, 60, 90, 125 and 250
rpm. The highest potential differences in the substrate variation showed
relatively similar results, however they were achieved in different times,
which the speed was dependent on the complexity of the substrate molecular
structure. While the agitation of 90 rpm gave the highest potential difference.
These results indicates that tofu whey potential to be used as a MFC substrate.
