Method for degrading fungal toxins in animal bodies through lactobacillus acidophilus

Abstract

The invention belongs to the technical field of toxin degradation, and discloses application of lactobacillus acidophilus in degradation of fungal toxins in animal bodies. The fungal toxins comprise T-2 toxins, aflatoxin B1, deoxynivalenlo and ochratoxin; lactobacillus acidophilus liquid is uniformly sprayed to animal feed, litopenaeus vannamei and tilapia mossambica are fed with feed containing lactic acid bacteria and feed containing the T-2 toxins, the aflatoxin B1 (AFB1), the deoxynivalenlo (DON) and the ochratoxin (OTA) for ten days, and fungal toxin residues in the muscles of the litopenaeus vannamei and the tilapia mossambica are significantly reduced compared with a control group, wherein the T-2 content in the litopenaeus vannamei muscles is decreased by 63.86%+/-1.32%, the AFB1 content in the litopenaeus vannamei muscles is decreased by 53.04%+/-0.97%, the DON content in the litopenaeus vannamei muscles is decreased by 70.74%+/-1.47%, the OTA content in the litopenaeus vannamei muscles is decreased by 70.24%+/-1.22%, the T-2 content in the tilapia mossambica muscles is decreased by 54.93%+/-2.52%, the AFB1 content in the tilapia mossambica muscles is decreased by 42.10%+/-1.97%, the DON content in the tilapia mossambica muscles is decreased by 48.75%+/-0.93%, and the OTA content in the tilapia mossambica muscles is decreased by 32.79%+/-1.81%. Accordingly, the lactobacillus acidophilus is prepared into a feed additive, then the fungal toxins accumulated in the animal bodies can be degraded, and the practical application value is achieved.

Description

technical field [0001] The invention relates to the technical field of toxin degradation, in particular to a method for degrading mycotoxins in animals by using Lactobacillus acidophilus. Background technique [0002] Mycotoxins have toxic effects on humans and animals. At present, there are more than 200 kinds of mycotoxins known, and quite a few of them have strong mutagenic, carcinogenic and teratogenic effects. Known toxin-producing fungi mainly include: Aspergillus, Penicillium, Fusarium and so on. T-2 toxin, aflatoxin B 1 (AFB 1 ), deoxynivalenol (DON) and ochratoxin (OTA) are toxic metabolites produced by mold growth. They are common mycotoxins naturally occurring in shrimp feed and fish feed. They are highly toxic, difficult to remove, and stable in nature. They can cause shrimp and The occurrence of fish diseases and the decline in production performance and muscle quality have caused huge economic losses to the aquaculture industry and hindered the development o...

Problems solved by technology

T-2 toxin, aflatoxin B 1 (AFB 1 ), deoxynivalenol (DON) and ochratoxin (OTA) are toxic metabolites produced by mold growth, which are common mycotoxins naturally occurring in prawn feed and fish feed. They are highly toxic, difficult to remove, and stable in nature. The occurrence of fish diseases and the decline in production performance and muscle quality have caused huge economic losses to the aquaculture industry and hindered the development of the aquaculture industry. At the same time, fish and shrimp products containing mycotoxins directly or indirectly endanger human life, health and safety through the transmission of food chains , therefore, effective control of its harm is an imminent hot issue

[0003] Lactic acid bacteria, as probiotics, are widely used in various product applications. At present, there are many reports on the degradation of mycotoxins in vitro by lactic acid bacteria, but the types of toxins degraded by single bacteria are limited, and the effect is not good. In addition, they cannot play a role in animals. , cannot play the role of degrading mycotoxins accumulated in animals
