Besides , it has a good efficiency using pvp - i to remove p . globosa red tide at the prophase of logarithmic phase Pvp - i在棕囊藻生长指数期前期具有良好的除藻效果。
An exponential growth curve starts off slowly and increases faster and faster as time goes by ( called the log phase ) 指数生长曲线开始时很低,但随时间的增长,其增长得越来越快(称为指数期) 。
In addition , the growing of cells in the process of decolorization implicated the exponential growth phase of n strain lagged behind that of decolorization 此外,通过生长细胞脱色过程中对菌体生长的相应测定表明,该菌株生长的指数期明显滞后于染料脱色的指数期。
Further experiment of decolorization by different carbon source demonstrated that n strain firstly degraded reactive violet kbr because of its detoxication , then entered the exponential growth . previous test verified that rhodopsedomonas palustris had a good ability of decolorization 我们又测定不同碳源时染料的脱色过程,进一步证明这是细菌出于自身的解毒功能先降解活性紫kbr ,而后开始进入生长指数期。
3 . the growth dynamic of artificial vegetation in shapotou region in shapotou area , the growth curve of shrubs was like the form of " s " . the stagnant period of growth was in april , the exponential period of growth was from may to july , the stable period of growth was from august to october 3 、植被生长动态:研究区内灌木植物生长曲线呈s型,生长停滞期在4月左右,生长指数期在5月到7月,生长静止期在8月到10月, 10月前后停止生长。
