Kokuto-shochu is a traditional Japanese distilled liquor made from brown sugar. Kokuto-shochu distillery wastewater (KDW) contains high concentrations of organic compounds and brown pigments (called molasses pigments) which are hardly decolorized by general biological wastewater treatment. A fungus, Penicillium oxalicum d, which we isolated in a previous study, decolorizes 47% of the color from KDW without the addition of any nutrients.

Large quantities of deeply pigmented molasses distillery wastewater (MDW), are discharged during the production of bio-ethanol from molasses. Conventional biological wastewater treatment is not effective in removing the molasses pigments. In the present study, a MDW treatment system was developed with combination treatment involving biodecolorization and biotreatment by Aspergillus tubingensis DCT6, together with physical decolorization by ozonation after treatment by activated sludge.

Pot ale from a pilot-scale malt whisky distillery was treated using a mesophilic upflow anaerobic sludge blanket (UASB) digester. Stable operation was observed at organic loading rates (OLRs) of 5.46 kg COD/m3 day or less when the pot ale was diluted with tap water.

Distillery wastewaters generated by ethanol production from fermentation of sugar-cane molasses, named vinasses, lead to important ecological impact due to their high content of soluble organic matter and their intense dark-brown color. Taking advantage of the well-known ability of white-rot fungi to degrade an extensive variety of organic pollutants, the capacity of Trametes sp. I-62 (CECT 20197) to detoxify this type of effluents was evaluated.
