This invention discloses a method for preparing mother cultures from wild bamboo fungus tissue isolation, belonging to the field of agricultural technology. The method uses naturally grown wild bamboo fungus buds or open-capped bamboo fungus as raw materials, obtains the stipe-coated portion through tissue isolation, and finally cultivates and purifies it to obtain the mother culture. This invention effectively utilizes collected wild bamboo fungus resources, solving the problem of effectively isolating mature or open-capped bamboo fungus, and laying a technical foundation for the collection of high-quality bamboo fungus germplasm and the breeding of superior varieties.

The invention discloses extraction of Ganoderma subflexioides exopolysaccharides and preparation of capsules, and belongs to the technical field of microorganisms, the Ganoderma subflexioides exopolysaccharides obtained by the method are high in purity and strong in activity, and in-vitro cell experiments prove that the exopolysaccharides have a remarkable protection effect on HepG2 cell injury induced by carbon tetrachloride. The traditional Chinese medicine composition can be used for preparing liver-protecting medicines to achieve the effect of preventing or treating hepatocyte injury. The polysaccharide particles in the ganoderma sub-bent-handle exopolysaccharide capsule prepared by the method are good in appearance, relatively high in forming rate, good in moisture absorption resistance, high in flowability and constant in quality. The research broadens the new form of converting ganoderma lucidum fungus resources into products at present, promotes the application of a fermentation technology in the aspect of large fungus culture, and promotes the application of the fungus resources in the health fields of medical treatment, health care and the like.

The application discloses a sesquiterpene compound from an endophytic fungus of Alpinia speciosa, a preparation method and application. The application separates 7-butyl-4-methoxyoxepin-2(5H)-one with antibacterial activity from liquid fermentation culture of endophytic fungus Xylaria curta YSJ-5 of Alpinia speciosa, as shown in formula (I). The 7-butyl-4-methoxyoxepin-2(5H)-one is a new sesquiterpene compound, and shows good antibacterial activity to MRSA and SA, and the MIC value is 6.3 mu g / mL. The application provides a candidate drug for researching and developing a new antibacterial drug, and provides a scientific basis for developing and utilizing the endophytic fungus resource of Alpinia speciosa.

The present application relates to the technical field of remote sensing image processing and ecological monitoring, and provides a grassland mushroom ring remote sensing identification method and system based on multispectral threshold screening and geometric constraint, computer equipment, computer readable storage medium and computer program product, the identification method comprising: S1, multispectral remote sensing image acquisition and preprocessing; S2, vegetation index construction and ring band feature enhancement; S3, adaptive threshold screening to generate candidate binary graph; S4, morphological arc breaking repair and connected domain candidate region extraction; S5, geometric constraint fitting and parameter extraction; S6, false target suppression and consistency verification; S7, identification result output.
