Little is known about the influence of minerals and other soil factors on the biocontrol activity of Trichoderma spp.The objectives of this study were to first evaluate the take-all–suppressive activity of T.koningii in field soils representative of the wheat-growing region in the Pacific Northwest of the United States,and then to identify abiotic edaphic parameters that are positively and negatively associated with the biocontrol activity of T.koningii in these soils.Such information will be usefulin selecting sites where T.koningii can be expected to perform optimally;in developing formulations that enhance biocontrol;and perhaps in indicating factors that favor mechanisms involved in the biocontrol activity of this strain such as antibiotic and enzyme biosynthesis.

知之甚少，对矿物和其它土壤因素对生物活性木霉镰刀本研究的目的首先评估全蚀抑制活性t.koningii土壤代表小麦种植区在西北太平洋的美国，然后找出生物土壤参数有积极和消极与生物防治活性t.koningii在soils.such这些信息将有助于在选择地点，可以t.koningii预计进入最佳状态；在发展制剂提高生物防治；或许说明因素，有利于参与机制，在生物防治活动，这株如抗生素和酶的合成。

The RRS intensity was enhanced obviously after the drugs and DNA reacting with each other, which indicated the formation of new products for the maximum peak appeared at around 375 nm with slight red shift. Then the Cu ion was added into the system to form a ternary system, and the RRS intensity was enhanced significantly, when the enhanced spectral value was directly proportional to the concentration of the DNA. Thus a highly sensitive method could be obtained for determining DNA and the detection limit of the experiment reached 9.7 ng/mL for the RFSV system.

两者反应形成结合产物后其RRS明显增强，并在375 nm左右出现最大散射峰，且有不同程度的红移和散射增强，说明两者结合成新的产物；加入Cu2＋离子后， Cu2＋与利福霉素抗生素及DNA形成三元复合物，此时将导致RRS进一步剧增，而且RRS光谱增强值与DNA浓度呈正比，因而可用于DNA测定具有较高的灵敏度，实验对ctDNA的检出限为9.7 ng/mL (RFSV-Cu2＋- ctDNA体系)。

The experimental conditions were optimized to produce following results: good linearity of sulfamethoxazole, norfloxacin, ciprofloxacin, ofloxacin and tetracycline in the range from 1.00 ng/L to 1 000 ng/L and the limits of quantification 1 ng/L, the good linearity of terramycin and aureomycin in the range from 10.0 ng/L to 2 000 ng/L and the LOQ 10 ng/L, the recoveries of deionized water and surface water from 72.1% to 112%, and the RSD from 0.6% to 9.2%.

Pf7-14 was chosen to study the spatial-temporal colonization patterns on both rice flag leaves and rice stems under greenhouse conditions by spraying 1×10〓 cfu/ml bacterial suspension of Pf7-14 at late booting stage, periodical sampling, and recovering the bacteria through diluting-plate method as well as graphic test and the Shapiro-Wilk test for normality of the data.

以菌株Pf7-14为代表，在温室条件下，在水稻孕穗后期喷雾浓度为1×10〓cfu/ml的菌悬浮液，然后定期取样，用稀释平板法在含抗生素Nal的培养基上回收细菌，并通过图形测试和Shapiro-Wijk正态测试，测定了该菌株在水稻剑叶和茎基部的时间、空间定殖型。

By contrast, many thiazine antimicrobials, antimalarials and antibiotics formed strong donor-acceptor interactions with vitamin K. While the anticoagulant effect of this interaction was not examined, potentially this may be responsible for the increased anticoagulant effect observed with warfarin in the presence of these drugs.

相反，许多噻嗪类精神药物、抗菌剂、抗疟药、抗生素和抗凝剂与维生素K相互作用形成牢固的供体-受体复合物，而此时此相互作的抗凝效应还未检测到，华法林与这些药物合用后抗凝效应增强可能与此现象有关。

Dozal et al.(3), studied the charge transfer donor-acceptor complexes which form between three classes of vitamin K and several thiazine psychotropes, antimicrobials, antimalarials, antibiotics, and anticoagulants.
