1Evaluating the effectiveness of marine actinobacterial extract and its mediated titanium dioxide nanoparticles in the degradation of azo dyes显示文摘Aim of the present study was to synthesize titanium dioxide nanoparticles(TiO2 NPs) from marine actinobacteria and to develop an eco-friendly azo-dye degradation method. A total of five actinobacterial isolates were isolated from Chennai marine sediments, Tamilnadu, India and analyzed for the synthesis of TiO2 NPs using titanium hydroxide. Among these, the isolate PSV 3 showed positive results for the synthesis of TiO2 NPs, which was confirmed by UV analysis. Further characterization of the synthesized TiO2 NPs was done using XRD, AFM and FT-IR analysis. Actinobacterial crude extract and synthesized TiO2 NPs was found efficient in degrading azo dye such as Acid Red 79(AR-79) and Acid Red 80(AR-80). Degradation percentage was found to be 81% for AR-79, 83% for AR-80 using actinobacterial crude extract and 84% for AR-79, 85% for AR-80 using TiO2 NPs. Immobilized actinobacterial cells showed 88% for AR-79 and 81% for AR-80, dye degrading capacity. Degraded components were characterized by FT-IR and GC-MS analysis. The phytotoxicity test with 500 μg/mL of untreated dye showed remarkable phenotypic as well as cellular damage to Tagetes erecta plant. Comparatively no such damage was observed on plants by degraded dye components. In biotoxicity assay, treated dyes showed less toxic effect as compared to the untreated dyes.S Priyaragini S Veena D Swetha L Karthik G Kumar K V Bhaskara Rao 2014Journal of Environmental Sciences2014,26,4:4
2米糠油同时脱胶脱蜡物理精炼新技术显示文摘对米糠油同时脱胶脱蜡物理精炼新工艺进行了小试研究,并在此基础上进行了生产试验。毛米糠油与氯化钙水溶液混合,在低温下结晶(20℃)使水化磷脂和非水化磷脂与蜡一起沉析分离,随后进行脱色和冬化(20℃)处理,进一步将磷脂含量降到5mg/kg以下,再经物理精炼,即可使成品精炼米糠油满足市售商品对其色泽(10~12罗维朋值,25.4mm槽)、游离脂肪酸含量(〈0.25%)和浊点(4~5℃)的要求;且中性油损失少。米糠油含有多种生物活性物质,如谷维素,VE和甾醇。本工艺可在最终产品中保留80%以上的生物活性物质。Rajam L Soban Kumar D R Sundaresan A Arumughan C 武丽荣(译) 2006中国油脂2006,31,7:3
