Assessment of citric acid production in the presence of 3-[4-(bromomethyl)phenyl]-7-(diethylamino)

The efficacy of 3-[4-(bromomethyl) phenyl]-7-(diethylamino) on bioproduction of citric acid by some fungal strains such as Aspergillus carbonarius NCIM -1962, Aspergillus saitoi, NCIM - 1364, Aspergillus usumii NCIM - 1576, Aspergillus wentii NCIM - 1981 and Aspergillus niger NCIM - 2690 has been assessed. It has been found that the fungal strain Aspergillus niger NCIM -2690 has been found most suitable to give higher yield of citric acid. The coumarin; i.e. 3-[4-(bromomethyl) phenyl]-7-(diethylamino) under trial has stimulatory effect on bioproduction of citric acid and enhances the yield of citric acid to an extent of 12.324% higher in comparison to control fermenter flasks, i.e., 6.776 g/100 ml in 12 days of optimum incubation period, 2.0pH and 250C temperature with 20% (w/v) molasses solution alongwith other nutritional ingredients.
