Optimal conditions for oxalic acid production by Aspergillus niger and A. flavus
The cultural optimum conditions for oxalic acid production from two fungi isolates viz. Aspergillus niger and A. flavus were studied by, including carbon, nitrogen source, salts and pH. The results showed that the molasses can be used as a carbon source of the acid production and its best concentration was 5.6 for both isolates, while the best nitrogen source was the ammonium sulphate with production of 24.1 and 21.3g/l for both fungi, respectively. Based on the results, KH 2 PO 4 0.1+MgSO 4 .7H 2 O 0.05% was the best compound for production. pH value with higher mount of acid production was 6.5.
期刊介绍：
Iranian Journal of Ichthyology (IJI) is a peer-reviewed journal for publication of high quality papers on any aspect of ichthyology and will be published 4 times a year by the Iranian Society of Ichthyology (http://www.isi-org.ir). The journal welcomes the submission of manuscripts that meets the general criteria of significance and scientific excellence, and will publish original scientific articles in the fields of ichthyology. The editors welcome the submission of original manuscripts including Research Articles, Short communications, and Views & News. Review papers by distinguished authors and Special Issues will also be considered. It is our aim to provide the international scientific community with an efficiently published journal, meeting high scientific and technical standards. Scopes of Iranian Journal of Ichthyology includes: Systematics, taxonomy, morphology, anatomy, biogeography, biodiversity, conservation, ecology and general biology of fishes (reproduction, food and feeding habits, age and growth, population dynamics, etc.). Papers on freshwater, brackish, marine and fossil fishes will be considered.
