抑菌测定

objective to study the effects of rabdosiae serrae compound preparation on staphylococcus aureus biofilm.methods minimal inhibitory coh centration were tested by doubling dilution,and simulate s.aureus biofilm in vitro be improved brown plate method.the effects of r.serrae compound preparation in different mic on s.aureus biofilm were determined and confirmed by scanning electronic microscope.single layer cells of human floss film were used to test the toxic effects of the compoud preparation.results the mic of s.serrae compound to s.aureus was 128?

目的 研究溪黄草复方对金黄色葡萄球菌生物膜的影响。方法采用试管二倍稀释法测定药物的最低抑菌浓度，用brown平板改良法体外复制金黄色葡萄球菌生物膜模型，并检测溪黄草复方的不同mic浓度对金黄色葡萄球菌生物膜的影响，扫描电镜确认。采用人绒毛膜单层细胞体外培养检测受试药物的毒性作用。结果溪黄草复方对金黄色葡萄球菌的mic值为128？

Methods The Chinese herbal was pureed, and adopted the methods of agar dilution recommended by NCCLS to investigate the MIC of Chinese herbal on the three different kinds of bacteria.

将黄连、黄芩制成煎剂，采用美国临床实验室标准化委员会推荐的琼脂稀释法，测定此2种药物对3种细菌的最小抑菌浓度。

Soil samples were collected from different ecological conditions. More than 70 Streptomyces hygroscopicus strains were isolated from the soil samples. Fermentation centrifugal supernatant of the strains were used as biocontrol agents to bioassay the seedling of rice and barnyard grass and rice pathogens of sheath blightand bakanae. Three strains showed good effects of inhibitingbarnyard grass seedling, the another three strains well inhibited the growth of rice pathogenic fungi.

从国内外不同生态条件下采集的土壤标本中分离到70多个吸水链霉菌，用其发酵离心上清液对水稻、稗草秧苗和稻纹枯病菌、恶苗病菌进行生物测定，结果有3个菌株对稗草根的生长具有较好的抑效果；有3个菌株对水稻病原菌有很好的抑制生长作用。
