Aspergillus versicolor for fermenting Jatropha cake to manufacture biological bacterial manure

Abstract

The invention relates to an Aspergillus versicolor for fermenting a Jatropha cake to manufacture biological bacterial manure, belonging to the field of manure. The Aspergillus versicolor provided by the invention is named as Aspergillus versicolor A003. The stain is preserved in a preservation unit designated by State Intellectual Property Office, the preservation date is 18th, July 2011, the name of the preservation unit is China Center for Type Culture Collection, and the preservation number is CCTCC NO: M2011240. When the Aspergillus versicolor is inoculated on a culture medium mainly prepared from the Jatropha cake, the Jatropha cake can be quickly fermented, toxic components in the Jatropha cake can be eliminated, the detoxified Jatropha cake and live thalli growing on the Jatropha cake can be used as biological bacterial manure and can promote the growth of various crops.

Description

Technical field [0001] The invention belongs to the field of biological bacterial fertilizer, and relates to an aspergillus versicolor capable of fermenting jatropha cake, degrading its toxic components and promoting the growth of various plants. 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 curcas L. (also known as Jatropha curcas, 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, By-products cannot be fully utilized and other issues. [0003] The jatropha cake is rich in nutrients, and the nutrients in the jatropha cake can be used as a medium for microbial growth to ferment to make biological fertilizer. B...

Problems solved by technology

The problem with this method is that since Cystis is a plant symbiotic bacterium, it cannot leave living plants and must be cultivated with living plants, which is not conducive to the large-scale and rapid cultivation of the bacterium.

[0008] Because jatropha cakes contain certain antibacterial substances and high protein content, many microorganisms cannot grow rapidly on jatropha cakes and cannot degrade toxic components in jatropha cakes. Jatropha Cake Fermentation Can Remove the Toxicity of Jatropha Cake and Promote the Growth of Plants

Aspergillus versicolor is a common microorganism in the environment. It has been found through research that it can grow rapidly on the medium prepared with Jatropha cake as the main component, but there is no report on the use of Aspergillus versicolor for biological fertilizer
