A total of 12 cheeses were considered for the study 4 kinds of imported cheese made from raw milk, 4 kinds of imported cheese made from pasteurized milk, and 4 kinds of domestic cheese made from pasteurized milk, and aerobic count, presence of E. coli, Salmonella spp., and Listeria monocytogenes were investigated. Results from this study showed that in the 12 different kinds of cheese tested, E. coli, Salmonella spp., and Listeria monocytogenes were negative. Therefore, the sanitary conditions of imported cheese made from raw milk, imported cheese made from pasteurized milk, and domestic cheese made from pasteurized milk are considered safe. The mean aerobic count in the 12 types of tested cheese was below 4.0 log CFU/g. In conclusion, various cheeses produced from raw milk or pasteurized milk currently sold in Korea have been found to be hygienic and safe. In the future, raw milk cheeses produced and sold in Korea will require long-term research not only to ensure safety but also to produce new, high-quality products.","PeriodicalId":117724,"journal":{"name":"Journal of Milk Science and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130271923","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}

Developments of antibacterial drugs are largely aimed to target the bacterial envelope, but screening their efficacy on bacterial envelope is laborious. This study presents a potential biosensor for envelope-specific stress in which a gfp reporter gene fused to spy gene encoding a periplasmic chaperone protein Spy (spheroplast protein y) that can sense envelope stress signals transduced by two major two-component signal transduction systems BaeSR and CpxAR in Salmonella enterica serovars Enteritidis and S. Gallinarum. Using spy-gfp operon fusions in S. Enterititis and S. Gallinarum, we found that spy transcription in both serovars was greatly induced when Salmonella cells were forming the spheroplast and were treated with ethanol or a membrane-disrupting antibiotic polymyxin B. These envelope stress-specific inductions of spy transcription were abrogated in mutant Salmonella lacking either BaeR or CpxR. Results illustrate that induction of Spy expression can be efficiently triggered by two-component signal transduction systems sensing envelope stress conditions, and thereby suggest that monitoring the spy transcription by spy-gfp operon fusions would be helpful to determine if developing antimicrobials can damage envelopes of S. Enteritidis and S. Gallinarum.","PeriodicalId":117724,"journal":{"name":"Journal of Milk Science and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123056151","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}

From two groups containing 7 cows each, a group was fed in-door with TMR (total mixed ration) feed and whereas the other group was grazed pastures for 12 h. The daily intake of feed on basis of dry matter (DMI), milk yields, concentration of milk constituents, and fatty acid profile of pasture milk were compared with control TMR milk. In addition, the physiochemical properties and composition of unsaturated fatty acids of the butter were also compared with those of the butter made from control TMR milk. Upon comparison, the health-promoting index (HPI) of fatty acids; the ratio of omega-6 fatty acids to omega-3 fatty acids (n-6 to n-3 UFA), the atherogenicity index (AI), and the ratio of linoleic acid to α-linolenic acid (LA to ALA) was apparently improved in farm butter than those of control butter. Thus, it could make the dairy farm visitors to consume the farm butter containing the health-promoting fatty acids from the milk of cows grazing on mountain pasture.","PeriodicalId":117724,"journal":{"name":"Journal of Milk Science and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121958113","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 results showed that this extract exhibited antibacterial activities against Bacillus cereus (complete inhibition) and Staphylococcus aureus (partial inhibition), but did not inhibit the growth of Cronobacter sakazakii and Salmonella Enteritidis. This study shows that the Aronia melanocarpa (black chokeberry) ethanol extract was more effective against Gram-positive bacteria than Gramnegative bacteria. Hence, it is suggested that Aronia melanocarpa could be a useful food supplement, and could be utilized as a naturally derived additive for maintaining the safety of various dairy products. Furthermore, future research should be conducted to examine the possibility of using such products as functional ingredients for improving the antioxidative and anti-inflammatory activities of food products.","PeriodicalId":117724,"journal":{"name":"Journal of Milk Science and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114642266","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}
