为了探究铁离子对铜绿假单胞菌(PA)的影响,在缺铁及加铁条件下探究PA绿脓杆菌(PAO1)的生长状态,结果发现缺铁离子限制PAO1的生长.利用蛋白质组学质谱技术检测PAO1在不同铁离子条件下的蛋白表达差异,结果表明与合成绿脓菌素相关的吩嗪类蛋白在缺铁条件下表达量发生显著上调;定量检测结果验证PAO1在缺铁环境中产生绿脓菌素的量相较于加铁环境显著增加;通过检测外源加入的绿脓菌素对PAO1在缺铁及加铁条件下生长状态的影响,表明绿脓菌素会导致PAO1在生长初期生长缓慢且在生长中期菌体密度显著下降. PA生长状态的变化可能是由于缺铁条件下PAO1产生的绿脓菌素对其自身的杀伤作用所致.

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.
