Bacillussubtilis for decomposing aflatoxin and active protein secreted by same

Abstract

The invention relates to a bacillussubtilis (Bacillussubtilis ANSB324 CGMCC No.3609) for decomposing aflatoxin, protein secreted by the same and an application thereof. The invention also provides a method for decomposing aflatoxin B1, G1 and M1 by using fermentation liquor of the strain or the protein secreted by the strain. By the method, after the bacillussubtilis and the aflatoxin B1 react for 48 hours, the decomposition rate of the B1 reaches 85%; after the bacillussubtilis and the aflatoxin G1 react for 72 hours, the decomposition rate of the G1 reaches about 66%; and after the bacillussubtilis and the aflatoxin M1 react for 72 hours, the decomposition rate of the M1 reaches about 68%. For the bacillussubtilis and the active protein secreted by the bacillussubtilis, the detoxifying activity is high, the specificity is strong, the action effect is mild, therefore, the bacillussubtilis provided by the invention is applicable to decomposing and removing the aflatoxin in feedstuff. Simultaneously, the bacillussubtilis provided by the invention has the advantages of strong bioactivity, good probiotics and stress resistance, and the like, and does not damage nutrient components in the feedstuff.

AI Technical Summary

Benefits of technology

This patented bacilli are effective at reducing harmful substances from crops such as wheat or barley grapefruit (Citrus reptans). They also help improve food safety without affecting their taste qualities like flavor. These microorganisms produce enzymes that break down certain compounds found naturally occurring within crop plants called phytotrienols which cause them' symptoms including reduced growth rates due to lack of oxygen supply during storage periods. Additionally, these bacteria provide benefits related to improving digestibility when fed into animals through ingestion.

Problems solved by technology

This patent describes various ways for controlling the amount of certain substances present in crops like wheat germ meals without causing negative side impacts on animals and plants themselves. However, current techniques involve expensive processes involving multiple steps, which may result in reduced productivity due to increased risk from pesticides used in agricultural products.
