ENZIMA NITROGENASA PDF

La actividad del complejo enzimático nitrogenasa se midió cada tres horas a . También se ha encontrado actividad de la enzima nitrogenasa en el sistema. 29% mostró actividad de la enzima nitrogenasa. Estos resultados muestran que las BFNA-HC’s pueden ser una opción para biorremediar suelos contaminados. La nitrogenasa es un heterodímero formado por cuatro subunidades y hierro en el medio será uno de los factores que influya en la actividad del enzima.
