Abstract

It relates to Bacillus velezensis, a culture method and use thereof; Bacillus velezensis TA-3-BV serving as an endogenous antagonistic strain of sweet cherry for the first time, and a nucleotide sequence of 16S rDNA of the Bacillus velezensis TA-3-BV is shown as SEQ ID NO. 1. The Bacillus velezensis TA-3-BV has board-spectrum antibacterial activity for sweet cherry, has an inhibitory effect on a variety of pathogenic fungi, and especially has an excellent inhibitory effect on Rhizopus stolonifer serving as a soft rot pathogen of sweet cherry, with an inhibition rate of 69.82±1.43%; in addition, the Bacillus velezensis TA-3-BV has a good inhibitory effect on the postharvest rot of sweet cherry fruits, can slow down the rot process of fruits, can delay the rot of fruits by 2-3 d, thereby providing a novel method for postharvest preservation of sweet cherry.
