| 1 | Comparative study of polyhydroxyalkanoates production from acidified and anaerobically treated brewery wastewater using enriched mixed microbial culture显示文摘The production of polyhydroxyalkanoates(PHA) from wastewaters using microbial mixed cultures(MMC) has been attracting increased interest because of PHA's biodegradability characteristics. Production of PHA by an MMC enriched with PHA-accumulating bacteria was compared using anaerobically treated and acidified brewery wastewaters under various feeding strategies, namely pulse and batch feed addition. To obtain an enriched MMC, a sequencing batch reactor was inoculated with activated sludge fed with acetate and subjected to aerobic dynamic feeding. The enriched MMC was able to accumulate PHA up to 72.6% of cell dry weight(CDW) with pulse addition of acetate controlled by the dissolved oxygen(DO) concentration in the reactor. In a batch accumulation experiment with acetate,the PHA content achieved(28.5% CDW) was less than that of the pulse feeding strategy with the same amount of acetate(~2000 mg C/L). Using anaerobically treated and acidified brewery wastewater fed in pulses, the maximum PHA accumulated by the enriched MMC was similar for both wastewaters(45% CDW), in spite of the higher volatile fatty acid concentration in acidified brewery wastewater. The pulse feed addition controlled by the DO concentration was difficult to implement for wastewater as compared to acetate because the difference in DO concentration between substrate availability and depletion was low. For the batch addition of acidified wastewater, a slightly lower PHA content(39%CDW) was obtained. These results show that both brewery wastewaters can be utilized for PHA production with a similar maximum PHA storage capacity. | Pravesh Tamang Rintu Banerjee Stephan K?ster Regina Nogueira | 2019 | Journal of Environmental Sciences2019，31，4： | 5 |
| 2 | 等径角挤压对Cu-0.81Cr-0.07Zr合金第二相颗粒分布、硬度和电导率的影响显示文摘研究在室温和300℃下等径角挤压(ECAP)对Cu-0.81Cr-0.07Zr合金中第二相分布的影响,及其对硬度和电导率的影响。显微组织表征表明,经ECAP后,粗大的富Cr颗粒面积分数减小,这是由于塑性变形导致Cr的溶解。在室温下进行4道次ECAP后,由于固溶体中较高的Cr含量和基体中较高的缺陷密度导致电子散射的增加,合金的电导率下降了12%。仅在ECAP样品中观察到的Cu晶格常数的减小和差示扫描量热分析(DSC)过程中发生的放热反应证实了这些结果。经ECAP后的时效热处理促进额外的硬化效果和导电性的完全恢复,这是由于部分溶解颗粒的再沉淀造成的。在室温下进行4道次ECAP,然后在380℃时效处理1 h的合金具有更高的硬度(191 HV)和电导率(83.5%(IACS))。 | Filipe CALDATTO DALAN Gisele Ferreira de LIMA ANDREANI Dilermando Nagle TRAVESSA Ilshat Albertovich FAIZOV Svetlana FAIZOVA Kátia Regina CARDOSO | 2022 | Transactions of Nonferrous Metals Society of China2022，32，1： | 2 |
