乌蕨孢子繁殖技术的研究

研究了乌蕨(Stenoloma chusanum(L.)Ching)孢子无菌繁殖和常规繁殖方法。结果表明,乌蕨孢子在1/4MS培养基培养时的萌发率最高,达85.3%;在1/2MS培养基中的配子体成苗率最高,达85.9%;1/2MS培养基是培养优质孢子体苗的最佳培养基;河沙与草炭土体积比为1∶1的混合基质是播种孢子的理想基质,孢子萌发率和配子体成苗率分别达到82.6%和73.4%;无菌繁殖和常规繁殖所得的幼孢子体苗移栽成活率均达90%以上。     

浅论电力企业安全文化建设

安全文化是企业内关于安全事务的观念、看法、行为模式和价值观的集合。安全文化决定企业安全管理水平和安全性能。在电力企业推广应用安全文化理论体系,有助于提高企业安全管理水平和安全性。     

巴东官渡汇流口网箱养鱼对附近水域水质的影响

对巴东官渡汇流口网箱养殖区进行了现场调查和实验室分析,结果显示其水质变化规律为网箱养殖区劣于控制断面区域,控制断面劣于背景和削减断面,同一断面水质基本相同,控制断面水质由网箱向外逐渐变好。主成分分析表明,不同养殖区对水体污染影响依次为：中华鲟养殖区>鸭嘴鲟养殖区>黄颡鱼养殖区>鲤鱼、草鱼混养区。各水质指标相关性分析表明,官渡Chla与总磷和氨氮高度相关;氨氮、总氮、总磷和高锰酸盐指数4个指标明显相关,说明其污染源具有同源性,该水域污染主要受到网箱养殖的影响。以超河流背景断面浓度5％作为划定超背景污染带的标准,网箱养鱼引起的氨氮超背景污染面积最大,约为网箱面积的10倍,高锰酸盐指数超背景污染面积最小,约为网箱面积的5倍     

后重建时代汶川大地震极重灾区旅游发展策略探析

2008年汶川大地震给四川省旅游业发展在短期内造成了极大困难,但也给当地遗留了大量的地震遗存,拥有重要的科学考查、科普教育和纪念价值。后重建时代极重灾区面临的旅游发展问题大同小异,虽然开发了许多新项目,但问题并没有从根本上解决。从当地自然环境禀赋各异、少数民族文化开发程度低、旅游商品外来化严重、旅游安全等方面分析了面临的各种问题,提出了具有针对性的对策和建议。     

Biodegradation of endosulfan-contaminated soil in a pilot-scale reactor-bioaugmented with mixed bacterial culture

A novel mixed bacterial culture was enriched from an endosulfan (6, 7, 8, 9, 10, 10 – hexachloro-1, 5, 5a, 6, 9, 9a-hexahydro-6, 9-methano-2, 3, 4-benzo (e) dioxathiepin-3-oxide) processing industrial surface soil. The cultures were successful in the degradation of aqueous phase endosulfan in both aerobic and anaerobic conditions. Using the cultures, endosulfan degradation in silty gravel with sand (GM) was examined via pilot scale reactor at an endosulfan concentration of 0.78 ± 0.01 mg g^{? 1} of soil, and optimized moisture content of 40 ± 1%. During operation, vertical spatial variability in endosulfan degradation was observed within the reactor. At the end of 56 days, maximum endosulfan degradation efficiency of 78 ± 0.2% and 86.91 ± 0.2% was observed in the top and bottom portion of the reactor, respectively. Both aerobic and anaerobic conditions were observed within the reactor. However, endosulfan degradation was predominant in anaerobic condition and the total protein concentration in the reactor was declined progressively down the soil depth. Throughout the study, no known intermediate metabolites of endosulfan reported by previous researchers were observed.     

Effect of culture time on the growth curve and power performance in a microbial fuel cell at a fixed amount of liquid culture

The microbial fuel cell uses the microorganism biochemistry to carry on the energy conversion. Concerning the experimental precision, the colony culture would be replaced by a fixed amount of liquid culture for Microbial fuel cell of Escherichia coli. The anode and cathode chambers whose each volume is 100 mL were utilized, the effective surface area of proton exchange membrane Nafion-117 is about 9 cm². In addition, the electrode area of carbon cloth is 20 cm². Three kinds of Escherichia coli, named as BCRC No. 10322, 10675 and 51534, respectively, would be selected. Results show that the electricity performance of Escherichia coli of BCRC No.51534 is better than the other microorganism studied because of having a larger open circuit voltage of 1.01 V and limiting current 22 mA, the maximum power density of 1342 mW/m^2, and average working power density of 295 mW/m² would be produced. These results would be useful to improve the performance of microbial fuel cell.
