Method for producing cellulose and polypeptide protein feed by fermenting with Aspergillus awamori

The invention discloses a method for producing cellulose and polypeptide protein feed by fermenting with Aspergillus awamori 1042-2 which belongs to the Aspergillus and has the collection registration number of M209142 in the China Center for Type Culture Collection (CCTCC). The method for producing the cellulose and the polypeptide protein feed comprises the following steps: A, selecting the Aspergillus awamori 1042-2; B, authenticating the Aspergillus awamori 1042-2, C, culturing the Aspergillus awamori 1042-2 liquid; D, fermenting the solid material; and F, postprocessing. The solid culture which is obtained by inoculating the Aspergillus awamori 1042-2 onto the solid culture medium and fermenting the Aspergillus awamori 1042-2 and the solid culture medium is baked to dry, ground, sieved and subjected to the detection of the enzyme activity and the polypeptide protein content. The method for producing the cellulose and the polypeptide protein feed is feasible and easy, the produced powdered cellulose has the CMC enzyme activity of 31397.1-41826.7 U/g and the FPA enzyme activity of 1779.3-2212.1 U/g, has good stability and can be produced on a large scale, and the produced polypeptide protein feed contains more than 35 percent of protein. The Aspergillus awamori 1042-2 can be used for fermenting the palm kernel dregs, other dregs and the vegetable fiber and producing the biological feed, the biological fertilizer, the biological fuel and can be also used in the food industry, chemical industry and the pharmaceutical industry. The polypeptide protein feed produced by fermenting with the Aspergillus awamori 1042-2 can be used as the additive of the protein of various feed.

Soil phosphorus activator, and preparation method, application method and application thereof

The invention provides a soil phosphorus activator, and belongs to the technical field of biological fertilizers. The soil phosphorus activator comprises, by mass, 0.01-0.1 part of group B metal oxide, 25-60 parts of aspergilli, 30-50 parts of Arbuscular mycorrhizal fungi, 8-12 parts of humic acid and 10-20 parts of bean crop straws; and the effective number of viable bacteria of the aspergilli inthe soil phosphorus activator is equal to or more than 1 * 10<8> CFU / g, and the effective number of spores of Arbuscular mycorrhizal fungi is equal to or more than 15 / g. The soil phosphorus activatorprovided by the invention can activate the phosphorus in wheat field soil, reduce the solidification of phosphorus to unavailable phosphorus, stimulate the absorption of the surrounding phosphorus bywheat roots, increase the utilization rate of a phosphorus fertilizer, reduce the application of the phosphate fertilizer and ensure the stable yield and the yield increase of wheat.

Method for separating amylase-producing microorganisms from soil

PendingCN114644984AInitial rapid screeningSimple methodFungiBacteriaAmylaseAlternaria
The invention belongs to the field of microorganisms, and relates to a method for screening microorganisms capable of producing amylase from soil and carrying out strain identification. A hydrolysis ring is generated by an iodine staining method for preliminary screening, and the enzymatic activity is determined by a 3, 5-dinitrosalicylic acid (DNS) colorimetric method, so that a strain with excellent enzyme production capacity is provided for industrial production. The result shows that the 31 screened strains capable of producing the amylase belong to 10 genus, and the 31 screened strains comprise 9 strains of bacillus (Bacillus), 1 strain of paenibacillus (Paenibacillus), 4 strains of streptomyces (Streptomyces), 2 strains of enterobacter (Enterobacter), 4 strains of Aspergillus (Aspergillus), 2 strains of paecilomyces (Simple), 7 strains of Penicillium (Penicillium), 1 strain of Alternaria (Alternaria) and 1 strain of Cladosporidium (Cladosporidium). Wherein the amylase activity of streptomyces, aspergillus flavus and aspergillus niger is relatively high.
