Abstract: | In India, cane molasses–based distilleries are major production centers of ethanol. These industries release a dark brown
colored effluent known as spent wash, which even after anaerobic treatment retains the color. The commonly used practices
of treatment fail to remove the color and COD. A novel fungal consortium was developed for the treatment of this recalcitrant
wastewater. The consortium was run on a bioreactor with undiluted distillery effluent for 40 days. In the first 14 days, 61.5%
color and 65.4% COD removal was achieved. Further, the fungi were able to use wheat straw as carbon source as evidenced by
scanning electron microscopy (SEM) while treating the distillery wastewater. It is expected that such a treatment step will
lead to development of a treatment technology for distillery wastewater without the need for diluting it. |
