Screening of Fungal Elicitor for Fermentative Production of Natamycin and Optimization of Induction Conditions

doi:10.7506/spkx1002-6630-201307041

Abstract

Abstract: Preliminary screening was carried out to obtain fungal elicitor that induces natamycin production by Streptomyces chattanovgensis. The optimal induction conditions were established by mathematical modelling mathematical modelling based on Box-Behnken experimental design and response surface analysis. The potent inducing effect of the fungal elicitors on natamycin production was confirmed. When fungal elicitor from Aspergillus niger was added to a final concentration of 122 μg/mL after 18.3 h natamycin fermentation and incubated for 78.5 h, the observed average yield of natamycin in fermentation broth was 2.89 g/L, 1.68 times higher than the blank control.

Key words: fungal elicitor, fermentation, natamycin, response surface analysis
