Embedding Bacillus velezensis NH-1 in Microcapsules for Biocontrol of Cucumber Fusarium Wilt.

ABSTRACT: Cucumber Fusarium wilt, caused by Fusarium oxysporum, is a devastating disease of cucumber and leads to enormous economic losses worldwide. The antagonistic bacterium Bacillus velezensis NH-1 suppresses F. oxysporum For a higher biological control effect, control-released microcapsules of NH-1 were prepared using cell immobilization technology. NH-1 cells were embedded in combinations of the biodegradable wall materials sodium alginate, chitosan, and cassava-modified starch to prepare control-released microbiological microcapsules. For the preparation of alginate single-layer microcapsules, the highest embedding rate of 72.60% was obtained by applying 3% sodium alginate and 2% calcium chloride. After the application of monolayer alginate microcapsules in soil, the number of bacterial cells
