Abstract:
3 strains of antagonistic bacteria were screened from healthy ‘Red Fuji’ apple peel by the flat panel separation,and the inhibition of antagonistic bacteria to blue mould was studied through the living test and in vitro test.The results showed that the bacteriostatic effect was obvious;the control effect of strain BF-2 reached 87.6%,and the inhibition rate of BF-3 was 33.3% in the confrontation experiment.The antagonistic bacteria were fermented with the beef extract peptone liquid medium,and there was bacteriostatic factor in fermentation medium,and the diameter of bacteriostatic ring caused by strain BF-3 zymotic fluid was 27.4 mm.The antibacterial ability was affected by the fermentation time and temperature.
