The direct use of dairy products for food purposes is characterized by a combination of high acidity and special organoleptic characteristics. Yeast cells play the role of active ingredients in them, as they have a pronounced lacto- and bifidogenic effect. Lactose-fermenting yeasts are considered one of the main objects of molecular genetics and are widely used as producers of a number of biologically active substances. In recent years, a fundamentally new direction of industrial processing of milk whey and chubat has been actively and purposefully formed, as well as the basis for obtaining derivative components, which are targeted products. The purpose of the research work: isolation and identification of lactose-fermenting yeasts from milk whey and chubat. Growth dynamics of yeast strains were studied in Sabouro's nutrient medium, under aerobic growth conditions, and were also carried out using the methods of Bradford and Glushanov. In the course of the study, the microbiological indicators and taxonomic composition of the microbial community of milk whey of \"Amiran\" LLP and chubat of \"Sarzhailau\" LLP were studied. Physico-chemical and organoleptic characteristics of dairy products were studied. 2 yeast strains were isolated from substrate samples. The morphological and cultural properties of the isolated yeasts were studied, and as a result, IL1 and IL2 strains were identified as IL1-Pichia fermentans, IL2-Pichia fermentans.","PeriodicalId":101644,"journal":{"name":"Eurasian Journal of Applied Biotechnology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129783226","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}

To address this problem, we propose a method for improving the sensitivity and specificity of detection of virulent clonal lines of bacteria or individual virulence plasmids in metagenomic samples. In this study, we used previously developed computational tools, Barcode Generator and Barcoding 2.0, to analyse gut microflora of laboratory mice infected with a pathogenic multidrug-resistant S. aureus and treated with cefazolin, an iodine-containing complex CC-195, and by a combinatorial treatment. We searched the metagenomic samples for representatives of pathogenic microflora using diagnostic genetic barcodes, which were designed based on the whole genome sequences of a collection of clinical isolates. Our results demonstrated a practical applicability of these diagnostic barcodes to monitor clonal lines of pathogens and even individual virulence plasmids in the environment. We also found that the novel drug CC-195 promotes a speedy restoration of the normal gut microflora disturbed by infection and administration of the antibiotic cefazolin.","PeriodicalId":101644,"journal":{"name":"Eurasian Journal of Applied Biotechnology","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129996254","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}

The following three general indicators assessing the deterioration of the epidemiological situation were identified: an increase in the incidence, a decrease in the coverage of preventive vaccinations, and the ignition of dormant foci of diseases. To assess the epizootic situation, additional indicators were identified, such as an increase in the incidence in animal population and changes in natural, climatic and soil conditions.
