Notes:
Abstract Nitrogenase activity, nitrogenase synthesis, and the growth of four species of Azospirillum were examined at 30°C and 42°C. Azospirillum brasilense Sp 7 did not synthesize nitrogenase at 42°C nor was the enzyme stable at this temperature. In A. lipoferum 708 and A. brasilense 12S the nitrogenase activity was stable at 42°C but the synthesis of nitrogenase was reduced. In A. brasilense Sp 9 the nitrogenase activity was stable and showed the highest C2H2 reduction activity at 42°C.
