Preliminary screening of Ni(II)metal tolerance and dye-decolorizing by Nocardiopsis sp.SD8

Objective:To reveal the screening of metal tolerance and dye-decolorizing of Nocardiopsis sp.Methods:NiSO_(4) and Congo red dye were used for evaluating the metal tolerance and dyedecolorizing of the randomly selected actinobacterial isolates.Results:Nocardiopsis sp.SD8 showed a better efficiency in Ni(II)tolerance,though a longer lag phase was observed for this microorganism grown for 7 days in integrated mismatch negativity.Interestingly,we also found that Nocardiopsis sp.SD8 had dye-decolorizing,hemolytic,lipase and protease activity.Conclusions:The present results revealed the bioremediation of metal resistant and diverse properties of Nocardiopsis sp.SD8 and further investigations are needed to extract and identify the potent molecule.
