EFFECTS OF DIFFERENT SULFUR SOURCES ON GROWTH AND DESULFURIZATION ACTIVITY OF Nocardia globerula R-9
Sulfate was identified as the final sulfur containing product of DBT desulfurization by Nocardia globerula R 9 by means of precipitation with barium chloride and Fourier transform infrared spectrometry The growth and desulfurization activity of cells grown with DBT, sodium sulfate or dimethyl sulfoxide as the sulfur sources were investigated The results showed that the said sulfur containing compounds could be used as the sulfur sources of this strain Furthermore, high concentration of sodium sulfate or dimethyl sulfoxide did not inhibit the growth of the strain For the specific desulfurization activity, the optimal concentration of sulfur source was about 2 mmol·L -1 .
