Abstract
The control of environmental pollution and the recovery of agricultural, industrial and municipal wastes by converting them into useful products are two relevant biotechnological goals. In this study, the possibility of utilising food industry waste and residues as sources of carbon for gibberellic acid production by Aspergillus niger was investigated. Media prepared from molasses, vinasse, whey, sugar-beet waste and fruit pomace were used and GA3 yields were found in concentrations 155, 136.57, 120, 73, 118.13 mg l−1 respectively in such media. It was observed that food industry wastes can be used and evaluated as cheap sources of carbon for gibberellic acid production.
