The invention discloses a bacterial strain antagonistic to pathogenic bacteria of jujube fruit shrink disease and an application of the bacterial strain. The antagonistic bacteria provided by the invention are bacillus subtilis STO-45 of which the microbial collection number is CGMCC No.9026. The bacillus subtilis STO-45 is separated from soil at the root of a healthy jujube tree and has remarkable and efficient antagonistic effect on the pathogenic bacterial of the jujube fruit shrink disease of jujube trees; the bacillus subtilis STO-45 further is capable of effectively inhibiting the alternaria tenuissima mycelia of the pathogenic bacteria of the jujube fruit shrink disease from growing and preventing and treating plant diseases induced by the pathogenic bacteria of the jujube fruit shrink disease; besides, the bacterial strain can be applied to the aspects of preventing and treating various pathogenic bacteria of the jujube fruit shrink disease, and jujube fruit anthracnose and a plurality of other tree diseases, and the like; and as a result, the bacterial strain is high in prevention effect and good in environmental safety, and has biological prevention and control potential as well as excellent development and application prospects.

The invention relates to a hybridoma cell strain 4F4 and an antibody thereof. The hybridoma cell strain 4F4 is preserved in China Center for Type Culture Collection on Dec. 27, 2016 with the preservation number of CCTCC NO:C201702. The hybridoma cell strain 4F4 generates an anti-tenuazonic acid monoclonal antibody, specifically detects tenuazonic acid, and is of great significance to detect the tenuazonic acid.

The invention discloses a loquat endophytic Trichoderma hacinatum strain and its application. An endophytic Trichoderma strain is isolated and obtained, subjected to morphological and molecular biological identification, and at the same time tested for its antibacterial activity. Materials provided for development and utilization; all exhibited antibacterial activity against five plant pathogenic bacteria, among which the inhibitory effect on fungi was significantly higher than that on bacteria, and the strongest inhibitory effect on Magnaporthe oryzae was 83.17%; followed by Alternaria adenocarpus, The bacteriostatic rate was 75.10%; the difference in the bacteriostatic rates of Fusarium laminarum and Elderberry was not significant, which were 52.02% and 49.07% respectively; It has broad-spectrum antibacterial properties and has the value and prospect of development and utilization.

The invention discloses alternaria alternata and an application thereof. The alternaria alternata HaoJ003 provided by the invention is preserved in China General Microbiological Culture Collection Center, with registration number of CGMCC No. 9852. Twenty eight tobacco related aroma components are detected from tobacco leaves which are processed by the alternaria alternata HaoJ003 CGMCC No. 9852 strain, wherein fourteen aroma compounds are not detected out from a control group, and the contents of other fourteen aroma components are improved in comparison with the control group, a nicotine content is reduced by 10.26% in comparison with the control group and the contents of harmful ingredients including one benzene, four phenols and the like are significantly declined in comparison with the control group; with the application of the alternaria alternata, tobacco aroma is enhanced, and meanwhile the contents of the harmful ingredients in the tobacco leaves are reduced; and the alternaria alternata can shorten a natural aging time and improve tobacco quality.
