The involvement of metal in oxidation and coupled phosphorylation by cell-free preparations of Mycobacterium phlei was examined. The oxidation of succinate was inhibited by metal-chelating agents, but with /3-hydroxybutyrate, chelating agents exhibited an uncoupling effect. The site of inhibition was found to be between the flavoprotein and the cytochrome b regions of the electron transport cha...
Whole cells of Mycobacterium phlei were shown to actively accumulate proline, leucine, lysine, tryptophan, histidine, glutamine, and glutamic acid to different steady state levels. The transport of proline, in contrast to that of other amino acids, was found to be insensitive to various respiratory inhibitors, e.g. cyanide, arsenate, azide, and sulfhydryl reagents. However, oxygen was an obliga...
The activities are reported of sodium salts of several n-alkylsalicylic acids against Staphylococcus aureus, Pseudomonas aeruginosa, Mycobacterium phlei, and Candida albicans. The acids had alkyl substituents of 1 to 18 carbon atoms in the 3, 4, or 5 positions relative to the carboxyl group of salicylic acid. Generally, the antimicrobial properties were typical of anionic surface-active agents ...
Dibenzothiophene (DBT) derivatives can be detected in diesel oil following hydrodesulfurization treatment, and they are widely recognized as target compounds for more efficient desulfurization. The moderately thermophilic bacterium Mycobacterium phlei WU-F1 was isolated for its ability to grow at 50 degrees C in a medium with DBT as the sole source of sulfur. At 50 degrees C, resting cells of W...
The marine endophytic fungus Coniothyrium cereale produces the structurally unusual polyketide-type alkaloids (-)-cereolactam (1) and (-)-cereoaldomine (3), incorporating a lactam and an imine functionality, respectively, as well as the related metabolite (-)-trypethelone (2). Compounds 1 and 3 showed selective inhibition of human leukocyte elastase with IC50 values of 9.28 and 3.01 μM, respect...
