The invention discloses a pichia cactophila strain BY35 for effectively controlling fruit postharvest diseases with advantages of wide antibacterial spectrum and stable effect and a using method of pichia cactophila. The strain has a strain collection number of CGMCC No. 14909 in China General Microbiological Culture Collection Center. The using method of the pichia cactophila strain comprises thefollowing steps: activating the strain, performing fermentation culture by YPD, centrifuging, and preparing the culture into bacterium suspension of 1*10<8>cells per mL with sterile water; adding apples, pears, grapes or citrus and the like into the bacterium suspension, soaking for 30 seconds, taking out the fruits, and airing; and putting into a preservation box, and storing at a normal temperature. The pichia cactophila is capable of simultaneously controlling apple penicillium disease and botrytis cinerea, penicilliosis and botrytis cinerea of pear fruits and fusarium wilt disease and anthracnose of grapes as well as blue mold of citrus fruits. Losses caused by the postharvest diseases are decreased, and the strain has excellent application prospects.

The invention discloses bactericidal agent compound which contains effective composition of propiconazole and can be applied in the prevention and cure of leaf spot which is hard to prevent and cure in agriculture and the application of the bactericidal agent compound. Composition A of propiconazole and composition B of imazalil are combined, and the mass ratio of the bactericidal agent compound is A:B=50-1:1-50. Auxiliary material is also included in the application and remixing of the compound, the composition A, the composition B and the auxiliary material are mixed to produce creaming agent, aqueous emulsion and suspending agent, two or more of the above are chosen as auxiliary material which is not limited within the above agents in the remixing. The compound is characterized in that by three times of applying the double bactericidal agent compound, the prevention and cure effect is at least 90 percent and at most 98 percent seven days after the last application of the compound. The compound is mainly applied for bananas and can also be applied for crops such as mandarin trees, wheat and the like, and has good prevention and cure effect for blue mold and green mold of mandarin trees, wheat sharp eyespot, root rot, powdery mildew and rust of wheat. The consumption of effect composition is decreased, costs are reduced, the occurrence of the drug resistance of bacteria is retarded, and environment pollution is decreased.

A Yangqi blue mold (CGMCC No.0668) able to generate alpha-galaotosidase and its application in preparing feed-class alpha-galactosidase by solid fermentation are disclosed. It features biologically that its colony can properly grow on malt wort plate for 7 days.

The invention provides green organic fertilizer for preventing diseases of grapes. The fertilizer is prepared from raw materials as follows: 25-35 parts of waste fungus chaff, 10-15 parts of cow dung,20-30 parts of peanut meal, 15-20 parts of peanut shells, 5-10 parts of a banana peel extraction solution, 4-10 parts of a leek root extraction solution, 5-9 parts of a purslane herb extraction solution, 0.6-1.4 parts of citric acid and 45-65 parts of water. Compared with the prior art, the fertilizer has the advantages that the fertilizer cost is low, waste is changed into wealth, besides, the fertilizer has comprehensive nutrients and can meet the growth requirement of grapes, so that planted grape leaves are greener, larger and richer, the grape health degree can be increased, and the disease resistance of the grapes can be improved. Besides, the fertilizer contains an antibacterial component and can effectively kill bacillus subtilis, staphylococcus aureus, aspergillus niger, mucor, blue mold and other bacteria and molds and prevent diseases of grapes.

The preparation GS115 / Ac-AMP2 can be used for refreshment for inhibiting fruit postharvest diseases.

The invention discloses a method for preventing blue mould pollution in koji made with soy sauce. The method comprises the following steps: after biological antagonistic yeast receives slant activation treatment, liquid extended cultivation is processed to the yeast; after being cultivated to be mature, the yeast accesses to koji material which has well stirred koji mold and is to be sent into a tank, with the addition of 10 to 10<7> pieces of yeast / g koji material, and then enters into the koji tank to make koji. The method uses the antagonistic yeast to prevent the blue mould pollution in the process of koji making; during the koji making process, the adding of the antagonistic yeast does not bring negative effect to the koji material and the soy sauce after fermentation, and can improve the quality of the soy sauce.
