Abstract

This work was carried out to locate the site of molybdenum reduction in S. marcescens strain DrY6 using several respiratory inhibitors. Based on the non-inhibitory results of the respiratory inhibitors tested such as antimycin A, rotenone, azide and cyanide, the site of molybdenum reduction in this bacterium is suggested not to be components of the electron transport pathway.
