| 1 | Enhanced cold active lipase production by metagenomic library recombinant clone CALIP3 with a step-wise temperature and dissolved oxygen level control strategy显示文摘A metagenomic library recombinant clone CAPL3, an Escherichia coli strain generated by transformed with metagenomic library from deep-sea sediments, can efficiently produce cold active lipase. The effects of both temperature and dissolved oxygen(DO) on cold active lipase production by batch culture of metagenomic library recombinant clone(CAPL3) from deep-sea sediment were investigated. First, a two-stage temperature control strategy was developed, in which the temperature was kept at 34 °C for the first 15 h, and then switched to30 °C. The cold active lipase activity and productivity reached 315.2 U·ml^(-1)and 8.08 U·ml^(-1)·h^(-1), respectively,increased by both 14.5% compared to the results obtained with temperature controlled at 30°C. In addition, different DO control modes were conducted, based on the data obtained from the different DO control strategies and analysis of kinetics parameters at different DO levels. A step-wise temperature and DO control strategy were developed to improve lipase production, i.e., temperature and DO level were controlled at 34 °C, 30% during 0–15 h;30 °C, 30% during 15–18 h, and 30 °C, 20% during 18–39 h. With this strategy, the maximum lipase activity reached 354.6 U·ml^(-1)at 39 h, which was 28.8% higher than that achieved without temperature and DO control(275.3 U·ml^(-1)). | Zhuhua Chan Runping Wang Fan Yang Runying Zeng | 2016 | Chinese Journal of Chemical Engineering2016，24，9： | 0 |
| 2 | 基于高空气球平台的下投探空:系统研发和青藏高原实验显示文摘为提高复杂地理环境和极端天气条件下的大气廓线探测能力,本文自主研发了基于平流层高空气球平台的下投探空系统,并在青藏高原开展探测评估实验.该系统主要由下投探空舱,携带降落伞的下投探空仪,下投施放装置,数据接收通讯天线和GPS模块等组成.下投探空仪测量数据通过卫星通信链路和无线电信号实时发送至数据接收机存储处理.2020年青藏高原实验中8枚下投探空仪全部成功施放,提供了合理有效的大气廓线探测数据.后续会进一步提高下投探空仪传感器性能,全面评估其探测准确性和精度. | Jinqiang Zhang Hongbin Chen Yunfei Du Wenzheng Shao Runping Zeng Keping Zhu Yi Liu Yuejian Xuan | 2021 | Atmospheric and Oceanic Science Letters2021，14，3： | 0 |
