3411 results about "Agar" patented technology

Agar (/ˈɑːɡər/) or agar-agar, is a jelly-like substance, obtained from red algae. Agar is a mixture of two components: the linear polysaccharide agarose, and a heterogeneous mixture of smaller molecules called agaropectin. It forms the supporting structure in the cell walls of certain species of algae, and is released on boiling. These algae are known as agarophytes, and belong to the Rhodophyta (red algae) phylum.

Liquid strain of edible mushrooms and method for producing liquid strain of edible mushrooms

The invention discloses a method for producing a liquid strain of edible mushrooms. The method for producing the liquid strain of the edible mushrooms comprises the steps that (1) the liquid strain of the edible mushrooms is inoculated in a PDA culture medium to be activated, and separation is conducted after cultivation so that an activated mycelium can be obtained; (2) the activated mycelium is inoculated in a solid-state saw dust culture medium to be cultivated for 28-32 days so that a recovery culture 1 composed of the mycelium and the solid-state saw dust culture medium can be obtained; (3) the recovery culture 1 is smashed into particles with the diameters ranging from 20 meshes to 40 meshes and then the particles are laid flat in a shallow plate with a thickness of 3 m-4m to be cultivated for 2-3 days in a sealed mode so that a recovery culture 2 can be obtained; (4) after the recovery culture 2 is smashed into small blocks with the diameter not larger than 0.5 cm, pulping is conducted by adding water to the small blocks, and then the obtained pulp and the agar solution with the concentration ranging from 0.15% to 0.2% are made to be in contact and evenly mixed. According to the method for producing the liquid strain of the edible mushrooms, operation is easy, a complicated cultivation device is not needed, and the production efficiency is high. The liquid strain, obtained according to the method, of the edible mushrooms has the advantages of being stable in quality, robust, slow in degeneration and easy to store and transport.

Method for preparing seaweed biological long-acting fertilizer

The invention relates to a method for preparing seaweed biological long-acting fertilizer. Seaweed dregs from which seaweed gum, carrageenan and agar are extracted are taken as an active carrier so as to turn waste into treasure, and a plurality of seaweed bio-active substances contained in seaweed extract and chelated-type nutritive elements or nutrients easily absorbed by plants are all wrapped up to form a slow-release system so as to ensure slow long-term release of fertilizer efficiency and provide plants with demand for nutrition throughout a growing season. The method extracts nutrient components in seaweed adopting a low-temperature extraction process, thereby ensuring that active components of the seaweed are not destroyed and increase the content of the effective nutrient components of products. The method adopts a special biochemical process, adds a multifunctional fermentation strain which has synergy and is formed mainly by compounding fungi, yeast, actinomycetes and bacterial beneficial microorganisms which are not mutually antagonistic and cooperate during fermentation, and effectively extracts biological nutrient components of the seaweed through a large amount of powerful biochemical reaction during reproduction. The seaweed biological long-acting fertilizer belongs to non-toxic pollution-free purely-natural seaweed bio-organic fertilizer.
