Biomass production and formulation of biocontrol yeast C andida membranifaciens
Journal of Crop Protection(2015)
摘要
In this study, the effect of carbon and nitrogen sources, on production of yeast biomass was determined as well as the efficacy of various formulations of Candida membranifaciens to decrease blue mold on apple. The media containing sugar cane molasses as carbon sources caused more yeast growth than the media supplemented with permeate powder. Yeast extract as nitrogen source produced higher biomass than urea and Corn steep liquor (CSL). The best growth was obtained in medium that composed of sugar cane molasses, yeast extract and CSL. Viability of C. membranifaciens differed in various carriers significantly (p < 0.01). The number of viable cells in Kaolin and Talc-based formulations was gradually reduced whereas the viability in wheat bran based formulations increased in 4 months and then gradually declined. In general, the formulations stored at 4 °C had longer shelf life than those stored at 24 °C. The antagonistic efficacy of prepared formulations of C. membranifaciens was evaluated against Penicillium expansum on apple at storage conditions. There were no significant differences among Talc-based, Kaolin-based and Wheat bran-based formulations of C. membranifaciens in reduction of blue mold.
