Embodiment 1
[0034] Embodiment one: a kind of bacillus subtilis, described bacillus subtilis is bacillus subtilis (Bacillus subtilis) Cy-29, is preserved in the Microbiology Center of China Committee for Culture Collection of Microorganisms, and is preserved in China General Microbiology Culture Collection Management Center, The date of deposit is July 12, 2013, and the deposit number is CGMCC 7916.
[0035] The present invention extracts and screens out a kind of Bacillus subtilis Cy-29 from the soil, which is originally derived from a soil sample of an orchard. The sample is serially diluted, separated and purified to obtain a strain that has an inhibitory effect on plant pathogenic fungi, and The strains were identified. Bacillus subtilis (Bacillus subtilis) Cy-29 and the antibacterial substances produced by its fermentation have a strong broad-spectrum antifungal effect, and have a good inhibitory effect on a variety of plant growth pathogenic fungi and fruit and vegetable storage fung...
Embodiment 2
[0042] Embodiment two: a kind of Bacillus subtilis, described Bacillus subtilis is Bacillus subtilis (Bacillus subtilis) Cy-29, is preserved in China Common Microorganism Culture Preservation Management Center, preservation date is July 12, 2013, preservation number for CGMCC 7916. The cells of Bacillus subtilis (Bacillus subtilis) Cy-29 are short rod-shaped, Gram staining is positive, and spores exist. On nutrient agar, colonies appear rough, low raised, with irregular edges, matt and opaque.
Embodiment 3
[0043] Embodiment three: a kind of Bacillus subtilis, described Bacillus subtilis is Bacillus subtilis (Bacillus subtilis) Cy-29, preserved in China Common Microbial Strain Preservation Management Center, preservation date is July 12, 2013, preservation number for CGMCC 7916. The cells of Bacillus subtilis (Bacillus subtilis) Cy-29 are short rod-shaped, Gram staining is positive, and spores exist. On nutrient agar, colonies appear rough, low raised, with irregular edges, matte and opaque. The 16S rDNA sequence of the Bacillus subtilis is 1589bp long, and its sequence is shown in SEQ ID No.1.
