Moreover, they can tolerant to KCl, MgCl2 and CaCl2. Phosphate solubilization of selected soil yeast isolates were detected in Pikovskaya's broth supplemented with various NaCl concentrations (ranging from 0% to 10%). They can solubilize insoluble phosphate at all NaCl concentrations. But with increasing NaCl concentration, phosphate solubilization was decreased and the best solubilization was occurred at 6 days incubation period. Above 10% NaCl concentration, these isolates cannot solubilize insoluble phosphate, Ca3 (PO4)2. On maize germination under NaCl stressed conditions, it was found that soil yeast isolates enhanced maize germination when compared with uninoculated treatment. Above 0.5% NaCl concentration, germination percentage of maize was obviously different between inoculated and uninoculated treatments. Like in phosphate solubilization, germination percentage was decreased with increasing NaCl concentration. At 2% NaCl concentration, germination was not found. So these isolates tolerated to some degree of NaCl, there is limited range for their functioning. After treating salt affected soils with soil yeast isolates for four weeks, salinity of treated soils was slightly decreased but total nitrogen content, K+, and available nutrients (P and K2O) were slightly increased when compared with those of untreated soil.","PeriodicalId":14165,"journal":{"name":"International Journal of Innovation and Applied Studies","volume":"15 1","pages":"524-533"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73375436","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}

These are separated by two distillation towers. In the first tower called (STRIPPER COLUMN T_101) that consist of so trays, lighter cuts of C10 that are called LIGHT END. Are separated and the product of the lower level of tis tower goes to the 2nd tower called. This one consist of 60 Trays. In the bottom of tower products that are heavier than C13 and called heavy end are separated, and the products of the tower, as main products of unit 100 go to the unit 200 for hydrotreating. The purpose of using two tower is that in lower temperatures lighter materials get separated and in higher temperatures higher materials get separated.","PeriodicalId":14165,"journal":{"name":"International Journal of Innovation and Applied Studies","volume":"26 1","pages":"171-177"},"PeriodicalIF":0.0,"publicationDate":"2012-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84658194","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}
