Overuse of bleach or using a bleach solution that is too concentrated results in the production of toxic substances that pollute the environment and disturb ecological balance 过量使用漂白水或使用浓度过高的漂白水,会产生有毒物质污染环境,破坏生态。
Procaryotic expression vector recombinant was transformed into competent bl21 , induced and expressed by iptg revulsant , explored the best inducing time and the best concentration of revulsant 将原核表达载体的重组质粒转化大肠杆菌bl21 ( de3 ) ,用iptg诱导物进行诱导表达,探索最佳诱导时间和诱导物的使用浓度。
Its " optimum concentration of trypan blue was from 0 . 005 % to 0 . 01 % ( w / v ) , the optimum volume was around 15ml / per petri dish ( 080mm ) . lbsp medium was easy to use and can be sterilized by 121 掳 c for 30 minutes 比较研究结果表明鉴定培养基的适宜条件是:锥虫蓝的使用浓度是0 . 005 - 0 . 01 ( w v ) ,培养基的用量为15ml皿左右,并可以采用0 . 1mpa高压蒸汽灭菌。
