The sources of remarkable PUFAs with more than carbon 20 were arachidonic acid from eggs and n-3 PUFAs from fish oils. The filamentous fungus Mortierella alpina 1S-4, which was found on screening of microorganisms accumulating PUFAs with more than carbon 20, produces triacylglycerols rich in arachidonic acid, i.e., ones reaching 20 g/l in concentration and containing 30-70% arachidonic acid as total fatty acids. Various mutants derived from M. alpina 1S-4 have led to the production of oils containing various PUFAs. Molecular breeding of M. alpina strains by means of manipulation of the genes involved in PUFA biosynthesis facilitates improvement of PUFA productivity and elucidation of the functions of their enzymes. This review describes practical production of arachidonic acid and its related PUFAs through mutant breeding, functional analyses of the genes of the enzymes involved in PUFA biosynthesis, and recent advances in unique PUFA production through molecular breeding.","PeriodicalId":16191,"journal":{"name":"Journal of Japan Oil Chemists Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79973599","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}

At a lower critical solution temperature (LCST) of around 32oC, PNIPAM chains show phase transition from coil to globule state. Therefore, solids on which the PNIPAM is grafted are expected to be applicable to a wide variety of industrial fields using expanding-shrinking proper ty depending on temperature. In this study, the structural changes of the PNIPAM chains grafted onto solid plates were investigated in aqueous solutions with an atomic force microscope (AFM) and a quartz crystal microbalance with dissipation (QCM-D). By AFM imaging, the transition of the grafted PNIPAM chains from brush to mushroom state was visualized. QCM-D signals showed significant change at around LCST, indicating that PNIPAM underwent a collapse by the dehydration of the chains. A complementary investigation indicated that a similar transition could be observed in solutions of high concentration electrolytes. It was also found that the grafting density of the PNIPAM chains had a critical role for the conformational behaviour of the PNIPAM.","PeriodicalId":16191,"journal":{"name":"Journal of Japan Oil Chemists Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90473369","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}

This over view summarizes several types of polymeric emulsifier and emulsification mechanism mainly in cosmetic field and describes recent studies of a new water-soluble amphiphilic polysaccharide HHMHEC. HHM-HEC formed a gel through aggregation of hydrophobic moieties in water and stabilized O/ W emulsions by the associative thickening mechanism.","PeriodicalId":16191,"journal":{"name":"Journal of Japan Oil Chemists Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90504288","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}
