| Description |
Sugar cane pressmud, a by-product of cane sugar manufacture, was used as a substrate for production of citric acid by Aspergillus niger CFTRI 30, in a solid-state fermentation system. Of the 170 g of sugar supplied, 131 g were consumed, with a 79% yield of citric acid over 120 h. Potassium ferrocyanide improved conversion to about 88% and lowered fermentation time by 24 h. Enrichment with sugar and NH4NO3 was essential to improve productivity. About 174 g citric acid/kg dry sugar cane pressmud were produced after 120 h in ferrocyanide-treated medium which initially contained 12.5% (w/w) effective sugar and 0.1% (w/w) NH4NO3. About 3% (w/w) of the original sugar present in the substrate was non-utilizable. This is the first report on the potential of sugar cane pressmud for citric acid production.
