Effect of Protein Crude Extract on Oxic/Anoxic Diauxic Growth of a Napdeficient Mutant of Paracoccus pantotrophus

Jun Yin, Wes Stevenson, Zhiling Guo, Ben Koopman and Spyros A Svoronos

In this study it is shown that addition of crude protein extract containing either membrane bound nitrate reductase (Nar) or periplasmic nitrate reductase (Nap) shortens the diauxic lag of denitrifying bacteria switched from aerobic to anoxic conditions. The specific growth rate under anoxic conditions, following resumption of exponential growth, was found to be linearly related to the extract dose.
