Abstract
The antimicrobial mechanism of totarol was studied using Pseudomonas a eruginosa IFO 3080. This diterpene inhibited oxygen consumption and re spiratory-driven proton translocation in whole cells, and oxidation of NADH in membrane preparation. NADH-cytochrome c reductase was inhibit ed by totarol while cytochrome c oxidase was not. NADH-DPIP reductase and NADH-CoQ reductase were also inhibited. The site of respiratory in hibition of totarol was thought to be near CoQ in the bacterial electr on transport chain.
