Abstract: | The effect of fosmidomycin and mevinoline, inhibitors of the nonmevalonate and the mevalonate pathways of isoprenoid biosynthesis, respectively, on the growth of 34 anaerobic and 10 aerobic prokaryotic strains was studied. Fosmidomycin at the concentrations used was shown to inhibit the growth of 9 (of 10) representatives of the family Microbacteriaceae, 4 (of 5) strains of Thermoanaerobacter, and 11 (of 12) strains of Clostridium, whereas mevinoline inhibited the growth of lactobacilli (Carnobacterium), methanogenic and sulfate-reducing bacteria insensitive to fosmidomycin. During the late growth phase, four strains of actinobacteria (of nine) accumulated the compound, which, upon oxidation, generates a long-lived free radical; three strains synthesized 2-C-methyl-D-erythritol-2,4-cyclopyrophosphate (MEC). It was concluded that the difference in the sensitivity of the organisms to fosmidomycin and mevinoline might serve as a test to differentiate several representatives of the family Microbacteriaceae. The use of mevinoline for inhibiting methanogens in ecological investigations seems to be promising.__________Translated from Mikrobiologiya, Vol. 74, No. 2, 2005, pp. 185–190.Original Russian Text Copyright © 2005 by Trutko, Dorofeeva, Shcherbakova, Chuvilskaya, Laurinavichus, Binyukov, Ostrovskii, Hintz, Wiesner, Jomaa, Akimenko. |
