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 technical field of cultivation.
Background technology
Boletus aereus (
phlebopus portentosu), also name Phlebopus portentosus is torrid areas preciousness, edible mushroom most favored by customers, be also current Boletaceae (
boletaceae) arteries and veins handle Boletus (
phlebopus) in unique a kind of bolete can cultivated 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, rich in nutritive value, high protein, low fat, be rich in the mineral element that the human bodies such as 17 kinds of essential amino acids and abundant phosphorus, potassium, calcium, magnesium, iron, zinc are necessary, be good healthy food and there is good medical value, deeply liking by consumer.Often be grown in natural environment flame tree (
delonix regia), mango (
mangifern indica), coffee (
coffea arabica), shaddock (
citrus grandis) and jack fruit (
artocarpus heterophyllus) etc. on the lower and neighbouring 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 carries 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, the optimum temperature 28 DEG C ~ 30 DEG C 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, and the low temperature preservation that general microorganism fungus kind routine uses and nitrogen ultra low temperature preserving process all can not effective preservation Boletus aereus bacterial classifications.4 DEG C of low temperature preservations, preservation is after 15 days, and mycelia is dead; Nitrogen ultra low temperature preservation, test in protectant, to add 20% glycerine and add 20% glycerine, culture presevation is carried out in the two kinds of process of 5% extra large bath sugar, preservation activates for 6 months, and result shows: the process adding 20% glycerine in protectant, and bacterial classification is all dead; Protectant adds the process of 20% glycerine, 5% trehalose, has 10% mycelia block germination and growth, but the experiment in cultivation result in later stage show bacterial strain there occurs 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 to the method for the preservation black cattle liver starter kind of simple and effective in edible fungus technical field of cultivation.
Summary of the invention
An 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 bacterial strain vigor for a long time, be difficult to the problem of preservation to solve its bacterial classification in black cattle liver cultivation and scientific research, 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.
