MUTANT STRAIN OF PARACOCCUS DENITRIFICANS (PD??) WITH INCREASED DENITRIFYING ACTIVITY, AND SPRECTROPHOTOMETRIC METHOD FOR MEASURING THE DENITRIFYING ACTIVITY IN REAL TIME

The invention relates to a mutant strain of Paracoccus denitrificans with a greater denitrifying metabolism or activity, providing greater speeds of uptake of NO3 and NO2 with the use of a lower quantity of bacterial biomass for the effective removal of said nitrogenated compounds which are residual contaminants in treated water and in some foods, wherein said greater level of denitrifying activity is obtained by completely removing the gene of the subunit ? as an inhibitor of the F1FO-ATPase, with the denitrification via Paracoccus denitrificans being carried out in anaerobic conditions. La presente invención se refiere a una cepa mutante de Paracoccus denitrificans que presenta una mayor actividad o metabolismo desnitrificante, proporcionándole mayores velocidades de consumo de NO3 y NO2 con el uso de una menor cantidad de biomasa bacteriana para la remoción efectiva de dichos compuestos nitrogenados que son contaminantes residuales en aguas tratadas y en algunos alimentos, donde dicha mayor actividad desnitrificante se obtiene removiendo totalmente el gen de la subunidad ? como inhibidor de la F1FO-ATPasa, llevándose a cabo la desnitrificación por Paracoccus denitrificans en condiciones anaeróbicas.
