On the other hand, although these HALAB also existed in fermented food containing salt, such as ripened cheeses, their derivation have not been revealed. Therefore, to elucidate HALAB diversity of isolation sources, we isolated HALAB from various sea-salts that may be used for fermented food production. Among the 23 kinds of solar sea-salts, the strains belonging to the genus Alkalibacterium were isolated from two kinds of French solar sea-salts by the enrichment culture. These isolates had halophilic and alkaliphilic properties, and were identified as Alkalibacterium putridalgicola originally isolated from marine environment. On the other hand, the isolates did not grow under 20% NaCl and required sugar compound for their growth, indicating that they may not stimulate growth but survive on the surface of solar salt. Based on these findings, it can be considered that HALAB existed in the marine environment will adhere and survive on the solar sea-salt and propagate to various salted food manufacturing environments.","PeriodicalId":117947,"journal":{"name":"Japanese Journal of Lactic Acid Bacteria","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124264366","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}

Bacterial surface adhesion factors are known to be the predominant bacterial molecules involved in host-microbe interaction. Moonlighting refers to the ability of proteins to exert multiple biologically important functions in gut bacteria. The moonlighting proteins have canonical functions in essential cellular processes, such as glycolysis, chaperone activity, and protein synthesis, whereas in their cytoplasmic form, following secretion and localization to the cell surface, they often exert additional functions as an adhesion factor. Here we review the moonlighting protein-mediated colonization process of the gut bacteria, with a focus on the elongation factor Tu (EF-Tu). In addition, we will introduce a new experimental method for evaluating the behavior of moonlighting proteins","PeriodicalId":117947,"journal":{"name":"Japanese Journal of Lactic Acid Bacteria","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126861908","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}
