The optimization procedure for the media components (NH4NO3, KH2PO4, MgSO4 , CuSO4 , ZnSO4, FeSO4 , and MnSO4) was carried out using Plackett-Burman design (PBD) for the screening and central composite design (CCD) for the optimization. The results obtained from PBD indicated that NH4NO3, KH2PO4 , and MgSO4 were the most significant components that affected the citric acid production. The maximum yield obtained by CCD was 50.23 g citric acid/kg rice straw. The rate of citric acid production by SSF after the optimization indicated a profit of about 65% for SSF without any nutrient addition and of about 27% for SSF without optimization. 2013-01-15T03:15:43Z 2013-01-15T03:15:43Z 2012 Article Turkish Journal of Engineering and Environmental Sciences, vol. 36 (1), 2012, pages 81-93 1300-0160 http://journals.tubitak.gov.tr/engineering/issues/muh-12-36-1/muh-36-1-7-1101-8.pdf http://hdl.handle.net/123456789/22965 en TÜBİTAK.
