First, the culture conditions for intracellular lipase production were examined, and then the activities of dried cells obtained from immobilization in Biomass Support Particles (BSPs) were compared with those of freely suspended cells.It was clear from cultivation of freely suspended cells that intracellular lipase activity for the interesterification reaction was enhanced sifnificantly by the presence of oleic acid, oil, and tea oil, but that the presence of glucose reduced the activity.The specific activity of dried cells within BSPs increased 7-fold compared with that obrained from freely suspended cells.The process presented here, using immobilization within BSPs, can provide cells directly as a catalyst with high activity, where cells become immobilized simply during batch operation, and no special preparation of cells is necessary. Therefore, the reaction system using dried cells immobilized within BSPs is a promising interesterifcation process for industrial applications.</div>","PeriodicalId":15702,"journal":{"name":"Journal of Fermentation Technology","volume":"66 4","pages":"Pages 441-448"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0385-6380(88)90012-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91260279","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}

When the digester slurry was mixed with acid mine water, anaerobic digestion, including sulfate reduction and methanogenesis, was enhanced. In the mixture of acid mine water and the digester slurry, sulfate reduction proceeded without diminishing methanogenesis. The digester slurry and its supernatant (SDF-sup) showed a significant capacity to act as a strong alkaline reagent, and the pH of the acid mine water was markedly elevated by the addition of the digester slurry of SDF-sup even at the low ratio of 1% (v/v). Precipitation of heavy metals in the acid mine water occurred as the pH was elevated by the addition of SDF-sup. When the digester slurry was added at the ratio of 5% (v/v) to acid mine water which had been pretreated with SDF-sup, the rate of sulfate reduction increased with increasing the concentration of sulfate in the mixture up to about 1,400 mg·l−1. In acid mine water pretreated with SDF-sup and supplemented with the digester slurry at the ratio of 5% (v/v), the maximum amount of sulfate reduced within 20 d of incubation was about 1,000 mg·l−1, and the maximum rate of sulfate reduction was about 120 mg SO42−·l−1·d−1.</div>","PeriodicalId":15702,"journal":{"name":"Journal of Fermentation Technology","volume":"66 1","pages":"Pages 43-50"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0385-6380(88)90128-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74788578","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}
