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 我們又測定不同碳源時染料的脫色過程,進一步證明這是細菌出于自身的解毒功能先降解活性紫kbr ,而后開始進入生長指數(shù)期。
The results showed that temperature 25 - 30 , ph7 . 0 , anaerobic and illuminated conditions were optimum for decolorization . when reactive violet kbr was decolorized as sole source of carbon and energy of n strain , the decolorization rate of reactive violet kbr was significantly correlative to cell concentration , however the decolorization specific activity of n strains was not affected markedly by cell concentration 結果表明,該菌株生長細胞脫色的最佳條件為溫度25 - 30 , ph7 ,厭氧條件下的脫色率遠遠高于好氧條件下的脫色率。染料作為該菌株唯一的碳源和能源脫色時,脫色率與細胞濃度呈極顯著相關,細菌脫色比活率保持在較恒定的水平。
