Cyanobacterial photo-driven mixotrophic metabolism and its advantages for biosynthesis

引用

Frontiers of Chemical Science and Engineering 2015年第3期9卷 308-316页

Cyanobacterium offers a promising chassis for phototrophic production of renewable chemicals. Although engineered cyanobacteria can achieve similar product carbon yields as heterotrophic microbial hosts, their production rate and titer under photoautotrophic conditions are 10 to 100 folds lower than those in fast growing E. colt. Cyanobacterial factories face three indomitable bottlenecks. First, photosynthesis has limited ATP and NADPH generation rates. Second, CO2 fixation by ribulose-l,5-bisphosphate carboxylase/oxygenase （RuBisCO） has poor efficiency. Third, CO2 mass transfer and light supply are deficient within large photobioreac- tors. On the other hand, cyanobacteria may employ organic substrates to promote phototrophic cell growth, Nz fixation, and metabolite synthesis. The photo-fermenta- tions show enhanced photosynthesis, while CO2 loss from organic substrate degradation can be reused by the Calvin cycle. In addition, the plasticity of cyanobacterial path- ways （e.g., oxidative pentose phosphate pathway and the TCA cycle） has been recently revealed to facilitate the catabolism. The use of cyanobacteria as ＂green E. colt＂ could be a promising route to develop robust photobiorefineries.

Effect of humidity on the surface adhesion force of inorganic crystals by the force spectrum method

引用

Chinese Science Bulletin 2001年第11期46卷 912-914页

作者： tang, j Wang, C Liu, MZ Su, M Bai, CL Chinese Acad Sci Inst Chem Beijing 100080 Peoples R China

Effect of relative humidity on the surface adhesion force of several inorganic crystals of mica, CaF2 and KC1 was studied by atomic force microscopy (AFM). The results showed that the magnitude of surface adhesion force is mainly dependent on the surface free energy of the adsorbed liquid film, but almost independent of the thickness of the film. Furthermore, the deliquescence on the crystal surface was investigated, which demonstrated the capability of the force spectrum method to monitor changes in ionic concentrations of adsorbed liquid film in real-time.

Mechanosynthesis and mechanochemical treatment of bismuth-doped vanadium phosphorus oxide catalysts for the partial oxidation of n-butane to maleic anhydride

引用

journal of Natural Gas Chemistry 2008年第3期17卷 232-237页

作者： Y. H. Taufiq-Yap Y.C. Wong Y.

Three Bi-doped vanadyl pyrophosphate catalysts were prepared via dihydrate route （VPD method）, which consisted of different preparation methods including mechanosynthesis, mechanochemical treatment, and the conventional reflux method. The catalysts produced by the above three methods were characterized by x-ray diffraction （XRD）, scanning electron microscopy （SEM）, and temperature programmed reduction （TPR）. Catalytic evaluation for the partial oxidation of n-butane to maleic anhydride （MA） was also carried out. The XRD patterns of all the Bi-doped catalysts showed the main peaks of pyrophosphate phase. Lower intensity peaks were observed for the mechanochemically treated Bi-doped catalyst （VPDBiMill） with two additional small peaks corresponding to the presence of a small amount of V5＋ phase. The TPR profiles showed that the highest amount of active oxygen species, i.e, V4＋–O- pair, responsible for n-butane activation, was removed from VPDBiMill. Furthermore, from the catalytic test results, the graph of selectivity to MA as a function of the conversion of n-butane demonstrated that VPDBiMill was the most selective catalyst. This suggests that the mechanochemical treatment of vanadium phosphate catalyst （VPDBiMill） is a potential method to improve the catalytic properties for the partial oxidation of n-butane to maleic anhydride.

Overview of surface ozone variability in East Asia-North Pacific region during IGAC/APARE(1994—1996)

journal of Environmental Sciences 2004年第4期16卷 599-609页

Shim Environmental Engineering Unit Department of Civil and Structural Engineering The Hong Kong Polytechnic University Hong Kong Department of Atmospheric Science Nanjing University Nanjing 210093 China Chinese Academy of Meteorological Science Beijing 100081 China Research Center for Advanced Science and Technology University of Tokyo Tokyo Japan Department of Atmospheric Science "National" Taiwan University Taipei Taiwan China Global Environmental Research Center Korea Institute of Science and Technology Seoul South Korea

Surface ozone(O\-3) was measured at Oki Island(japan), Cheju Island(South Korea), Lanyu Island(Taiwan Province, China), Cape D'Aguilar(Hong Kong SAR) and Lin'an, Longfenshan, Waliguan(China mainland) during january 1994—December 1996 as a component of IGAC/APARE(International Global Atmospheric Chemistry/East Asia-North Pacific Regional Experiment). This paper gave a joint discussion on the observational results at these stations over the study region. Investigations showed that the average of surface O 3 mixing ratios at the seven sites are 47.9±15.8, 48.1±17.9, 30.2±16.4, 31.6±17.5, 36.3±17.5, 34.8±11.5 and 48.2±9.5 ppbv, respectively. Significant diurnal variations of surface O 3 have been observed at Oki, Cheju, D’Aguilar, Lin'an and Longfenshan. Their annual averaged diurnal differences range from 8 to 23 ppbv and differ in each season. Surface O 3 at Lanyu and Waliguan do not show strong diurnal variability. Seasonal cycles of surface O 3 showed difference at the temperate and the subtropical remote sites. Oki has a summer minimum-spring maximum, while Lanyu has a summer minimum-autumn maximum. The suburban sites at D'Aguilar and Lin'an report high-level O 3 in autumn and low level O 3 in summer. Surface O 3 remains high in autumn and low in winter at the rural site Longfenshan. For the global background station Waliguan, surface O 3 exhibits a broad spring-summer maximum and autumn-winter minimum. The backward air trajectories to these sites have shown different pathways of long-range transport of air pollution from East Asia Continent to North Pacific Ocean. Surface O 3 was found to be strongly and positively correlated with CO at Oki and Lanyu, especially in spring and autumn, reflecting the substantial photochemical buildup of O\-3 on a regional scale. It is believed that the regional sources of pollution in East Asia have enhanced the average surface O 3 concentrations in the background atmosphere of North Pacific.

Genetic expression of chimeric antigen receptors (CAR) enables T cells to target and kill cancer cells in an MHCindependent manner, resulting in a potent antitumor response [1]. To date, more than 10 CAR-T cell products have been approved globally for the treatment of hematologic disorders such as relapsed/refractory B-cell acute lymphoblastic leukemia, non-Hodgkin lymphoma, and multiple myeloma [2,3].

Cloning of murine BRI3 gene and study on its function for inducing cell death

引用

Chinese Science Bulletin 2002年第5期47卷 375-378,441页

作者： Lin, LZ Yu, H Ying, MY tang, j Zhou, W Zhao, SY Li, CB Fudan Univ Sch Life Sci Inst Genet State Key Lab Genet Engn Shanghai 200433 Peoples R China

To understand the molecular mechanism of TNFα effects, the cDNA of murine BRI3 gene was cloned from the total RNA of murine brain endothelial cells (bEnd.3) treated with hTNFa by using the suppression subtractive hybridization (SSH) and the RT-PCR method. The fusion expression vector harbouring BRI3 gene and enhanced green fluorescence protein (EGFP) thus obtained were designated as pEGFP/I3. Then pEGFP/I3 was transiently transfected into L929 cells and the fusion protein EGFP/I3 was localized in cytoplasm. It is found that the expression of EGFP/I3 could induce cell death in L929 cells detected by TUNEL method and flow cytometry. And the overexpression of Bcl-2 in L929 cells can block cell death induced by EGFP/I3, indicating that murine BRI3 gene might related to the TNFα mediated cytotoxicity.
