Microcapsule manufacture for bio-controlling strain ANTI-8098A(Bacillus cereus)for bacterial wilt disease

Microcapsule for bio-controlling strain ANTI-8098A(Bacillus cereus)to control bacterial wilt disease was manufactured by coagulating method, using glutin and arabic gum as shell-materials. The effects of shell-material concentration. ANTI-8098A concentration,stirring speed and formaldehyde solidification on formation of mi-crocapsule were studied. Results showed that using 2.5% glutin. 2.5 arabic gum with 10%-30% ANTI-8098A under conditions of stirring speed at 400 r·min-1,1% formaldehyde for solidification could result in round micro-capsule with diameter of 30.8-57.3μm and 70% retention ratio of the bacteria, the germination rate of microcap-sule of bio-controlling strain ANTI -8098A was over 93%.
