The invention discloses a mushroom strain LV17 with the preservation number of CGMCC (China General Microbiological Culture Collection Center) No.42460 and an application of the mushroom strain LV17. The strain can efficiently synthesize up to 64 key aroma substances in liquid fermentation, the yield of a core flavor substance dihydro-2-methyl-3 (2H)-furanone stably reaches milligram per liter, and the relative odor activity value is up to about 3.1 * 10 < 5 >; high-valence terpenoids such as beta, beta-ionone and the like are also remarkably enriched, so that strong and pure flower fragrance-fruit fragrance-sweet fragrance composite characteristics are jointly formed. Electronic nose and GC-MS (gas chromatography-mass spectrometry) analysis show that the overall aroma intensity of the strain is obviously superior to that of a control strain, and the response values of bad sulfides and amines are not abnormal. The strain can be applied to the fields of natural spices, food aroma enhancement and the like, and an efficient microbial cell factory is provided for solving the problem of production of natural characteristic aroma substances.

A method for agricultural cultivation, domestication, or cultivation of truffle fungi, including a method for isolation and culture to produce pure truffle fungi or mini-truffles, typically species of the genus Tuber or Iamai. Examples of truffles include Tuber melanosporum, Tuber magnatum, Tuber aestivum, Tuber uncinatum, Tuber borchii, species of the genus Imaia, Tuber macrosporum, Tuber gibbosum, Tuber oregonense, and Tuberlyonii. The isolated pure truffles may then be cultured on a nutrient substrate, which may be, for example, fruits, nuts, grains, or parts thereof, to produce truffle-flavored foods. Non-limiting examples of such substrates include rye, barley, lentils, wheat, rice, soybeans, pecans, hazelnuts, pine nuts, walnuts, coffee beans, mustard, cocoa, sesame, sunflowers, grapes, blackberries, blueberries, cherries, kiwis, mangoes, raspberries, and huckleberries.

The present application relates to the technical field of agricultural fertilizer, and particularly relates to a functional proteoglycan organic fertilizer of lentinula edodes residue, a preparation method and an application method thereof.The organic fertilizer is composed of functional proteoglycan 40-60%, humic acid 15-30%, potassium dihydrogen phosphate 8-15%, biochar 5-10% and seaweed extract 5-10%, wherein the functional proteoglycan is prepared by mixing lentinula edodes residue, pleurotus ostreatus residue and agaric residue, is a proteoglycan with a molecular weight of 5-50 kDa and contains a beta-1,3 / 1,6-glucan structure; the preparation method comprises the steps of residue pretreatment, ultrasonic-assisted enzymatic hydrolysis, multi-stage membrane separation, concentration and drying, formula mixing, granulation and packaging and the like.The organic fertilizer has a dual function of promoting plant growth and activating the plant immune system, can significantly improve the disease resistance and yield of plants, and simultaneously improves the physical and chemical properties of soil; the preparation process is green and environmentally friendly, has high extraction efficiency and low energy consumption; and the pH value of the product is adjustable.
