筛选

Based on the fact that the dye probe can intercalate DNA duplex to emit fluorescence, a novel method for detection of DNA polymerase has been developed. The polymerization process has been indicated by fluorescent signal in real-time. Based on this assay, the influence of anti-tumour drugs on the activity of polymerase has been investigated.

The results indicated that the astaxanthin-hyperproducing strains of oceanic red yeast could be efficiently isolated on the selective medium containing β-ionone.

该实验结果表明在分离培养基中添加β-紫罗兰酮可选择性地分离海洋红酵母虾青素高产菌株，提高虾青素高产突变株的筛选效率。

As shown by the result, the biomass and astaxanthin content of oceanic red yeast was reduced due to the presence of β-ionone which inhibited the synthesis of carotenoids. The lethality rate of oceanic red yeast would attained 92.3% if 370 mg/L of the β-ionone concentration was contained in the plate medium. The oceanic red yeast mutated by ethyl methane sulfonate was cultured on plate medium containing 370 mg/L of the β-ionone. 200 mutants were randomly screened, positive mutants with increased the biomass, astaxanthin volumetric yield and astaxanthin specific yield accounted for 18% of the total strain, the mutants with higher biomass, astaxanthin volumetric yield and astaxanthin specific yield higher occupied 22.5%, 45% and 46%, respectively.

实验结果表明，在β-紫罗兰酮存在的情况下，由于类胡萝卜素合成受到抑制，海洋红酵母的生物量和虾青素合成量都减少；当平板培养基中β-紫罗兰酮浓度达到370 mg/L时，海洋红酵母的致死率为92.3%；在这种平板培养基上涂布经甲基磺酸乙酯诱变的海洋红酵母，随机筛选200个菌落，结果表明生物量、虾青素体积产率和细胞产率均有所提高的正突变株占18%，生物量、虾青素体积产率和细胞产率的单项指标有所提高的正突变株分别占22.5%、45%和46%。

The astaxanthin-hyperproducing mutants of oceanic red yeast were efficiently screened with β-ionone.
