  • 摘要:通过苯胺蓝平板法从陕西秦岭森林高度腐殖化土壤中分离得到一株具有高度碳源利用多样性放线菌AG-56,经16S rRNA鉴定为链霉菌属(Streptomyces),命名为Streptomyces AG-56,GenBank登录号KU925845.同时,考察了Streptomyces AG-56在液体条件下对苯胺蓝的降解能力.结果显示,菌株AG-56对苯胺蓝的3个波长(602、314、192 nm)吸收基团都具有不同程度的降解能力,并伴有物理吸附作用,其中对602 nm处基团具有最大的脱除能力,脱除率为72%.菌株AG-56在污水脱色方面特别是对三芳基甲烷类染料废水处理方面展现出了巨大的应用潜能.
  • Abstract:A Actinomycetes AG-56, which has the strong ability of utilizing diverse carbon source, was isolated from the soil sampled in Shaanxi Qinling forest by using Aniline Blue plate method. The AG-56 belongs to Streptomyces through 16S rRNA identification. The degradation ability of AG-56 for Aniline Blue was investigated in liquid culture media. The results show that all of the three group compounds in Aniline Blue with absorption wavelength of (602, 314 and 192 nm) can be degraded and adsorbed by AG-56. The maximal degradation rate was 72% for 602 nm group. Streptomyces AG-56 shows great potential in the wastewater decolorizing, especially in tri-aryl methane type dye wastewater.
