Production of gibberellic acid by Aspergillus niger using some food industry wastes.

The production of gibberellic acid by Aspergillus niger and the possibility of utilizing food industry waste and residues as the sources of carbon in media were investigated. Media prepared from molasses, vinasse, whey, sugar-beet waste and fruit pomace were used and GA3 yields were found in concentrations 310, 273.14, 120, 73, 118.13 mg/l in such media, respectively. It was observed that food industry wastes can be used as cheap sources of carbon for gibberellic acid production by Aspergillus niger.
