Selenium-rich high-effective oyster mushroom culture medium and preparation method thereof

Abstract

The invention discloses a selenium-rich high-effective oyster mushroom culture medium including the following components, by weight, lavender, residue of siraitia grosvenorii, bran of sorghum, embryo powder of highland barley, grass seed powder, konjac powder, mint leaves, wax gourd skin, shell fossil, mica powder, dry powder of leaves of Anredera cordifolia, ferrous sulfate, citric acid, potassium sorbate, active carbon, sugar, calcium carbonate, monopotassium phosphate, loofah seedling, aquatic weeds, zinc and selenium, tea polyphenol, fruit green pigment and carbon nano tubes. The oyster mushroom culture medium is prepared with the expanded loofah seedling and the aquatic weeds as main materials, which provide a loose, water-retentive and nutrition-rich growth environment to the oyster mushrooms. By means of the fruit green pigment and the zinc and selenium supported on the carbon nano tubes, absorption and utilization of cells of the oyster mushrooms to these substances is promoted, thereby promoting growth and metabolism of the oyster mushrooms. The culture medium can achieve culture requirement of high efficient and good color and mouth feel of the oyster mushrooms.

Description

technical field [0001] The invention relates to the technical field of edible fungus medium, in particular to a selenium-enriched high-efficiency medium for Pleurotus ostreatus and a preparation method thereof. Background technique [0002] The nutrition of edible fungi is extremely high. With the improvement of people's living standards, people's demand and requirements for edible fungi are gradually increasing. While improving the nutrition of the used fungi, it is also necessary to enrich the varieties of edible fungi. The development of green and environmentally friendly edible fungi with high nutritional efficiency and richness through cultivation technology is a hot spot in current research. [0003] As an enzyme active substance, its nutritional function is related to a variety of enzymes. It is a constituent element of some dehydrogenases, carbonic anhydrases and phospholipases. These enzymes play a role in the hydrolysis of substances in plants, redox processes and ...

Problems solved by technology

[0003] As an enzyme active substance, its nutritional function is related to a variety of enzymes. It is a component element of some dehydrogenases, carbonic anhydrases and phospholipases. These enzymes play a role in the hydrolysis of substances in plants, redox processes and protein synthesis. Important role; moreover, zinc nutrition participates in the synthesis of auxin indole acetic acid; at the same time, zinc nutrition can stabilize the necessary components of cell ribosomes and participate in the formation of chlorophyll, but inorganic zinc is easy to lose and the absorption efficiency is low

[0004] Carbon nanotubes can be used as the carrier of enzyme active substances to promote the entry of enzyme active substances into the cells of edible fungi and promote the growth of edible fungi; at the same time, with the increase of people's demand for organic colored food, genetic modification can increase the consumption of organic colored food. species, however, presents certain difficulties
