Pore single black fungus strain

Abstract

The invention relates to a pore single black fungus strain, relates to a black fungus strain, and aims at solving the problem of the existing black fungus strain used in the production that the single is unlikely to form in a pore, the yield is low and the quality is poor. The pore single black fungus strain is the black fungus HW15, belongs to the auricularia auricular and is preserved in China General Microbiological Culture Collection Center (CGMCC), the preservation address is Yard 3 No.1 Beichen West Road, Chaoyang District, Beijing, China, the preservation date is November 27, 2013, and the preservation serial number is CGMCC 8553. The sporocarp is single and solitary, the single rate of the pore black fungus production reaches more than 90 percent, the size of the black fungus is appropriate, the black fungus is rootless and in a bowl shape or a seashell shape, the back surface of the dry black fungus is gray, the front surface of the dry black fungus is black and glossy, the color of the front surface is greatly different from that of the back surface, the edge of the black fungus is round and smooth, and channels on the back surface is not obvious; the foaming rate of the dry fungus can reach 1: 15 to 1: 18.

Description

technical field [0001] The invention relates to a black fungus strain. Background technique [0002] The northeast region is the main producing area of ​​black fungus in my country, and the total output of black fungus in Heilongjiang Province accounts for more than 50% of the whole country. With the expansion of the production scale of black fungus and the improvement of output, the cultivation method and market demand are also changing. The cultivation method has gradually changed from large mouth and large ears to small holes and single-piece ears. The entity forms a single piece, which can greatly improve the quality and economic benefits of the black fungus. However, a specific black fungus variety is a prerequisite for the formation of a single piece of small hole ear, and most of the traits of the black fungus used in production are not suitable for the small hole ear. The main manifestations are: small holes do not form a single piece or the single piece rate is lo...
