Plackett-Burman design for screening of fermentation process parameters and their effects on L-methionine production
Plackett-Burman design for L-methionine production Abstract In the present study, economical fermentation medium process was developed to achieve the maximum production of L-methionine by Corynebacterium glutamicum through screening of different nutritional and physical parameters by Plackett-Burman design. A total of eleven process variables such as plantain as carbon source, groundnut as nitrogen source, CaCO3, K2HPO4, KH2PO4, biotin, MgSO4.7H2O, inoculum size, agitation speed, volume ratio of medium/fermenter and pH were used for screening experiments. The PBD model results suggested that seven variables namely plantain as carbon source, groundnut as nitrogen source, CaCO3, MgSO4.7H2O and KH2PO4 had shown a significant effect on L-methionine production, while remaining six variables didn’t show a much effect on Lmethionine production. The R2 value (0.99) of analysis of variance (ANOVA) recommended that the model used for response prediction is significant (p<0.05). In comparison with the unoptimized medium, 24% higher L-methionine production was obtained from the optimized medium and L-methionine production was found to be 5.6 g/l.
期刊介绍:
The Association of Biotechnology and Pharmacy (ABAP) will be useful to form a forum for scientists so that they can bring together to discuss and find scientific solutions to the problems of society. The annual meetings will help the members to share their knowledge and publish their research knowledge particularly by members and fellows of the Association and special care will be taken to provide an opportunity for young scientists. Besides this the association is planned to organize symposia, seminars and workshops on current developments of Biotechnology and Pharmacy particularly on the subject of current scientific interest, and the proceedings of which will be published regularly. And in view of the vast development of science and to disseminate the problems in publication of research work, an international journal of Current Trends in Biotechnology and Pharmacy has been started by ABAP.
