The addition of free amino acids (alanine, glutamic acid, serine, tyrosine, and tryptophan) to the medium enhanced the antimicrobial effect of recombinant strains F-116 and F-119 on food and raw material contaminant strains to varying degrees. The effect of isoleucine is most effective, which contributed to an increase in the inhibitory activity of the F-116 strain on Staphylococcus aureus up to 32,1% and on Escherichia coli up to 84%, which was not observed in the F-119 strain. The bactericidal effect of the recombinant strain F-119 on Escherichia coli increased when serine was added to the medium from 1900 to 2550 units/ml (according to chloramphenicol), i.e. by 34%, tryptophan - by 37% and tyrosine - by 55%. With the addition of glutamic acid for 15 hours of cultivation, the fungicidal activity on Aspergillus niger increased only in strain F-116 from 2600 to 3300 units/ml (according to nystatin), which amounted to 27%, on Candida albicans up to 40%. Tyrosine increased the activity of strain F-119 on Candida albicans to . 25%, and tryptophan – 26%. The strains had high superoxide dismutase activity (27,02–30 U/mg of protein).

The body weight of animals fed with the drug at doses of 12 and 20 g/kg, significantly increased at the end of the third month.

One of the ways to solve it is to create multifunctional products containing ferrocyanides (hexacyanoferrates) of transition metals as active substances. In medicine and veterinary medicine, enterosorbents based on compounds of this class are used as independent pharmacological agents, and in the form of composite preparations, which are obtained by fixing ferrocyanides on carrier substances of different origin and chemical composition. To study the possibility of using certain substances as carriers in the creation of new composite preparations and to assess their effect on the detoxification properties of ferrocyanides, the sorption efficiency of a number of mineral and organic substances with respect to Cd and Pb was studied. It was found that the background content of Cd and Pb in the tested substances does not exceed the maximum permissible levels of these toxicants in feed, feed additives and veterinary preparations. Under in vitro conditions, the biomass of the fungus Inonotus obliquus (chaga), the preparations ferrocin, bifezh and KhZh-90, zeolite tuff shivyrtuin, smectite dioctahedral, white soot and chitosan succinate have the greatest efficiency of Cd and Pb sorption (with respect to Cd – 50.4-89.0%, Pb – 58.3-95.1%). The combined presence of Cd and Pb reduces the sorption capacity of most of the tested substances by 1.6-63.6%.","PeriodicalId":491484,"journal":{"name":"Проблемы ветеринарной санитарии, гигиены и экологии","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135102875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
