A kind of black cattle liver starter kind method for preserving
Technical field
The present invention relates to a kind of black cattle liver starter kind method for preserving, belong to edible fungus culture technique field.
Background technology
Boletus aereus (
phlebopus portentosu), also name Phlebopus portentosus, be edible mushroom torrid areas preciousness, most favored by customers, be also current Boletaceae (
boletaceae) arteries and veins handle Boletus (
phlebopus) in the unique a kind of bolete that can cultivate with saprophytic cultivation method, be distributed in the ground such as Sri Lanka, Vietnam, Indonesia, Thailand, Brazil, Mexico, Australia, New Zealand and Yunnan Province of China, Guangxi and Hainan.Boletus aereus quality is fresh and tender, delicious flavour, nutritive value abundant, high protein, low fat, be rich in the necessary mineral elements of human body such as 17 kinds of essential amino acids and abundant phosphorus, potassium, calcium, magnesium, iron, zinc, be good healthy food and there is good medical value, liked by consumer.In natural environment, often grow in flame tree (
delonix regia), mango (
mangifern indica), coffee (
coffea arabica), shaddock (
citrus grandis) and jack fruit (
artocarpus heterophyllus) etc. near the lower and meadow of tree, and root mealybug in soil (
pseudococcus) also there is substantial connection, its special life style is just under study for action.At present can with cultivation saprophytic bacteria mode carry out artificial cultivation, and the host tree such as inoculation flame tree, coffee, shaddock, mango host tree is carried out bionic cultivation.
But the preservation of black cattle liver starter kind is a difficult problem always.Boletus aereus is a kind of high temperature edible mushroom, 28 ℃~30 ℃ of the optimum temperatures of suitable mycelial growth.Under existing technical conditions, its bacterial classification can not carry out preservation as saprophytic edible mushroom.Inventor shows the practical experience of Boletus aereus culture presevation for many years, all effective preservation Boletus aereus bacterial classifications of the conventional low temperature preservation using of general microorganism fungus kind and nitrogen ultra low temperature preserving process.4 ℃ of low temperature preservations, preservation is after 15 days, mycelia death; Nitrogen ultra low temperature preservation, tested in protectant, add 20% glycerine and add 20% glycerine, culture presevation is carried out in two kinds of processing of 5% extra large bath sugar, preservation activates for 6 months, result shows: in protectant, add the processing of 20% glycerine, bacterial classification is all dead; Protectant adds the processing of 20% glycerine, 5% trehalose, has 10% mycelia piece germination and growth, but the experiment in cultivation result in later stage show bacterial strain occurred serious degradation, mycelia weak, form that mycoderma is many, fruiting is irregular, fruit body weight saving and the underproduction serious.Therefore, there is the active demand of the method for the preservation black cattle liver starter kind to simple and effective in edible fungus culture technique field.
Summary of the invention
One of object of the present invention is to provide a kind of easy and simple to handle, black cattle liver starter kind method for preserving that can keep for a long time bacterial strain vigor, to solve the problem that in black cattle liver cultivation and scientific research, its bacterial classification is difficult to preservation, and offer reference for other boletes and the preservation of mycorhiza edible fungus species.Another object of the present invention is to provide a kind of black cattle liver starter kind preservation medium and the purposes of this medium in Boletus aereus cultivation and/or preservation.
