为明确紫花苜蓿(Medicago sativa L.)叶枯病病原菌种类及生物学特性,筛选出有效防治药剂,本试验于2023年8月在黑龙江省肇东市和大庆市分别采集紫花苜蓿叶枯病病样,采用组织分离法分离并纯化病原菌,依据柯赫氏法则验证致病性,通过菌丝生长速率法进行室内药剂筛选。形态学结合分子生物学分析结果表明,引起紫花苜蓿叶枯病的病原菌为黑附球菌(Epicoccum nigrum)。生物学特性研究结果表明,菌丝生长最适温度25℃、最适pH值为10,全光照条件有利于菌丝生长,菌丝在马铃薯蔗糖琼脂(Potato saccharose agar,PSA)培养基上生长速度最快,在水琼脂(Water agar,WA)培养基上生长速度最慢。碳源和氮源选择上,菌丝分别在麦芽糖和磷酸二氢铵上生长速度最快,在蔗糖和硝酸钾上生长速度最慢。室内药剂毒力测定表明,30%吡唑醚菌酯抑菌作用最强,半数效应浓度(Median effect concentration,EC 50)为0.2819μg·mL^(-1)。

Frontiers of Environmental Science & Engineering 2018年第4期12卷 25-32页

作者： Lin Lin ying-yu Li xiao-yan Li Environmental Engineering Research Centre Departmelt of Civil Engineering The University of Hong Kong Pokfulam Hong Kong China Shenzhen Engineering Research Laboratory for Sludge and Food Waste Treatment and Resource Recovery Graduate School at Shenzhcn Tsinghua University Shcnzhen 518055 China＊

For biological nitrogen （N） removal from wastewater, a sufficient organic carbon source is requested fbr denitrification. However. the organic carbon/nitrogen ratio in municipal wastcwatcr is becoming lower in recent years, which increases the demand for the addition of external organic carbon, e.g. methanol, in wastewater treatment. The volatile fatty acids （VFAs） produced by acidogenic fenncntation of sewage sludge can be an attractive alternative for methanol. Chemically enhanced primary sedimentation （CEPS} is an effective process that applies chemical coagulants to enhance the removal of organic pollutants and phosphorus from wastewater by sedimentation. In temls of the chemical and biological characteristics, the CEPS sludge is considerably different from the conventional primary and secondary sludge. In the present study, FeCI3 and PACI （polyalunfinum chloride） were used as the coagulants for CEPS treatment of raw sewage. The derived CEPS sludge （Fe-sludge and Al-sludge） was then processed with mcsophilic acidogenic fennentation to hydrolysc the solid organics and produce VFAs for organic carbon recovery, and the sludge acidogenesis efficiency was compared with that of the conventional primary sludge and secondary sludge. The results showed that the Fe-sludge exhibited the highest hydrolysis and acidogenesis efficiency, while the Al-sludge and secondary＇ sludge had lower hydrolysis efficiency than that of primary sludge. Utilizing ffie Fc-sludgc fermentation liquid as tbc carbon source for denitrificatiom more than 99%of nitrate removal was achieved in the main-stream wastewater treatment without any external carbon addition, instead of 35% obtained from the conventional process of primary sedimentation followed by the oxic/anoxic （O/A） treatment.

目的探讨MRI随访观察对非前列腺癌患者的诊断价值。方法对1992-05—2004-09在北京大学第一医院进行过2次及2次以上MR检查(MR复查与初次MR检查间隔时间1.5~97个月),并经病理或临床诊断为非前列腺癌的25位患者的临床资料和MR表现进行回顾性分析。比较初次和复查结果。结果25例非前列腺癌患者初次MR检查时,前列腺体积(114.63±14.48)mm3,前列腺内发现异常信号16例,外周带15例、中央腺体1例。复查时,前列腺体积(103.71±13.34)mm3,前列腺内发现异常信号15例,外周带14例、中央腺体1例。复查MR检查时16例定性诊断无变化;9例有变化。以上结果经统计学处理,除患者年龄初诊和复查时差异有统计学意义(P=0.00)外,其他差异均无统计学意义(P>0.05)。结论经确诊或临床诊断为非前列腺癌患者,常规MR随访常不能提供有价值的信息。
