Use of Probiotic Bacteria With Lactonase Activity to Protect Animals From Mycotoxins in Feed

Abstract

The article discusses the prospects for the use of probiotic microorganisms with lactonase activity, in particular, the evaluation of these microorganisms for the synthesis of such enzymes with lactonase activity as acyl homoserine lactonase (aiiA) and laccase (cotA). The participation of these enzymes in the mechanism of quorum quenching (Quorum Quenching, QQ) is considered. In the course of the work, the prevalence of two enzymes with lactonase activity was studied, based on the results, the most promising strains were identified, also confirmed the relationship of activity to suppress luminescence and the presence of the corresponding gene. The most promising of the studied strains can be used to protect animals from mycotoxins in feed.
