| Abstract: | Effects of yeast extract, glucose, peptone, soil extract and metal ions Ca 2 , Mg 2 , Fe 2 , Fe 3 , Al 3 , Mn 2 , Co 2 , Zn 2 , Li , Cu , Cu 2 , Ba 2 , Ni 2 on degradation of p nitrophenol(PNP)by DLL E4 (Pseudomonas putida) were studied. The results show that addition of a proper amount of yeast extract, glucose and peptone could promote the degradation of PNP by DLL E4, but the addition of soil extract could not. All the metal ions, except Li and 0.1mmol Fe 3 could affect removal of PNP by this strain. The effects of Ca 2 , Mg 2 and Mn 2 were low, the effects of Fe 3 , Fe 2 ,Al 3 , Ba 2 and Zn 2 were high when in high concentration, whereas the effects of Co 2 , Cu 2 , Cu and Ni 2 were high, too, even in residual concentration. |
