waste water from a molasses alcoholic fermentation plant (mww) was treated biologically with phanerochaete chrysosporium. the ability of this white-rot fungus to degrade the dark colored pigments present in mww and the consequent decrease the effluent's color was examined. the optimum concentration of mww for color removal was determined and set at the ratio of 1:10. the color changes during in...

Ethanol production has been carried out from molasses by yeast Saccharomyces cervisiae and Schizosaccharomyces pombe. The level of alcohol production from molasses by the use of both these organisms in continuous ethanol fermentation. The highest percentage of alcohol production by Saccharomyces cervisiae with specific gravity 1.032 was 7.20% whereas Schizosaccharomyces pombe showed 5.25% of al...

A microbial fuel cell (MFC) is a device that converts chemical energy into electricity through the catalytic activities of microorganisms. In the present contribution, we demonstrated the comparative electricity production capacity of Saccharomyces cerevisae and Clostridium acetobutylicum in two chambered MFC using Artificial Waste water. Temperature, pH, substrate concentration and addition of...

In this study rhamnolipid biosurfactant production was investigated in eighteen strains of Pseudomonas spp.. Rhamnolipid by these strains was determined by a spectrophotometric method in nutrient broth medium (NB). From the 18 strains screened, two Pseudomonas strains (Pseudomonas luteola B17 and Pseudomonas putida B12) which had produced the highest percentage yield of rhamnolipid were examine...

Rapeseed meal and waste molasses are two important agro-industrial by-products which are produced in large quantities. In this study, solid state fermentation and fungal autolysis were performed to produce rapeseed meal hydrolysate (RMH) using fungal strains of Aspergillus oryzae, Penicillium oxalicum and Neurospora crassa. The hydrolysate was used as fermentation feedstock for heterotrophic gr...

Waste residual molasses, a non-edible portion produced during the processing of sugarcane juice for the preparation of molasses, may be an alternative low-cost renewable substrate to the pricey food-grade molasses for xanthan production. Systematic strategies were applied to improve xanthan production with a newly isolated indigenous strain Xanthomonas campestris originated from Tezpur, Assam. ...

Across the world 125 to 130 million tons of sugar is produced every year. About 2/3 rd of this is produced from sugarcane and 1/3 rd from sugar beet. Sugar industry play an important role in economic growth of country but the effluent releases from the industry posses abrupt changes to water quality and cause water pollution which eventually causes health hazards. The variety of microbes presen...

Polyhydroxyalkanoates (PHA) are biodegradable and biocompatible green thermoplastics, synthesized by wide variety of bacteria as an intracellular carbon and energy storage intermediate. They are used as an alternative to nonrenewable petroleum derived plastics. The current interest in these biopolyesters is stimulated by the search for cost-effective capitalized production. This paper attempts ...

The discoloration of a biologically pretreated waste water stream from a molasses processing by ozonation and two advanced oxidation processes (O3/H2O2 and 03/7-irradiation, respectively) was studied. Colour removal occurred with all three processes with almost the same efficiency. The main difference of the methods applied was reflected by the BOD increase during the discoloration period. By o...
