Effects of GtoCFE prepared under various culture conditions on S. toebii growth curves. S. toebii was cultured in a N2 gas-flushed anoxic cultivation system with 0.2 mg ml-1 of various GtoCFEs (squares, prepared from aerobic culture; diamonds, prepared from microaerobic culture; circles, prepared from anaerobic culture). Each G. toebii was cultured for overnight under different culture conditions and the cell-free extract was prepared by following the methods section. Nitrite production was used as a measure of S. toebii growth. The G. toebii growth curve (as measured by optical density at 600 nm) under the anaerobic culture condition was shown in the inset.
