Embodiment Construction

[0032] 1. Prepare the culture medium according to the ratio of jatropha cake: water at 1:1, sterilize it according to the conventional method for 60 minutes, cool it, and inoculate it with Aspergillus versicolor original variant A003 ( Aspergillus versicolor A003) strain, after 2 days of cultivation, Aspergillus versicolor is overgrown in the culture medium, and the grown jatropha cake is dried to obtain the detoxified jatropha cake detox feed.

[0033] 2. Prepare liquid medium according to the ratio of jatropha cake: water 1:10, put 100ml of jatropha cake liquid medium in a 500ml conical flask, sterilize at 1 atmosphere for 30 minutes, cool down, and inoculate Aspergillus versicolor A003 , cultivated at 28°C and 200rpm for one week, dried and dehydrated to obtain the detoxified jatropha cake.

Abstract

The invention provides an Aspergillus versicolor strain for manufacturing detoxicated feedstuff through the fermentation of Jatropha curcas cakes, relating to the field of feedstuff. In the invention, the Aspergillus strain is named Aspergillus versicolor A003; the strain was preserved by China Center for Type Culture Collection (a preservation unit specified by Patent Office of State Intellectual Property Office) on July 11th, 2011; and the preservation number is CCTCC NO:M2011249. By inoculating the strain onto a culture medium prepared from Jatropha curcas cakes used as main components, the Jatropha curcas cakes can be fermented quickly, and toxic components in the Jatropha curcas cakes can be removed; and the detoxicated Jatropha curcas cakes can be used as protein feedstuff for feeding animals.

Description

technical field [0001] The invention belongs to the field of feed and relates to Aspergillus versicolor for degrading toxic components in jatropha cake. Background technique [0002] With the increasing shortage of petroleum resources, vigorously developing biomass energy is an inevitable strategic choice for my country to improve energy security and ensure energy supply. Jatropha ( Jatropha curcas L. (also known as Tung Tung, Jatropha curcas, etc.) belongs to the Euphorbiaceae Jatropha genus, and is considered to be a suitable tree species for the development of biodiesel, but its industrial development is still in the early stage, and there are high costs and by-products that cannot be fully utilized And other issues. [0003] With the rapid economic development, China has become the largest breeding country in the world. Protein raw materials are the foundation of the development of the feed industry. The shortage and high price of protein raw materials have become and...
