抑制农业病害真菌的海洋微生物筛选及发酵工艺优化
Screening of Marine Microorganisms and Optimization of Fermentation Technology for Inhibiting the Agricultural Disease Fungi
摘要
Abstract
[Objective]The aim was to screen the marine microorganisms with strong antagonism to the agricultural disease fungi.[Method]Five kinds of agricultural disease fungi were selected as screening models,and the isolated strains were screened by Petri dish antagonism.The active strains were rescreened,and the strain with highest activity was selected to optimize the fermentation process.[Result]There were 21 strains of marine bacteria that had antagonistic effects in the initial screening.The bacteriostasis effect of MB133 strain on the plate ofP yricularia oryzae was most obvious after rescreening.The bacteriostasis effects of MB025,MB026 and MB133 strains on Sclerotinia sclerotiorum,Colletotrichum capsic and Botrytis cinerea were also found.The optimum fermentation process of MB133 strain was as followed:the optimum liquid amount was 12%,and the optimum inoculation amount was 2.0%,the optimum medium was pH 7.0.[Conclusion]This research has laid the resource base for the pop-ularization and application of agricultural antibiotics.关键词
