Isoprenoid quinones of the genus Legionella.
Representative strains of each of the named species of Legionella were examined for isoprenoid quinones by reverse-phase thin-layer chromatography. All strains contained three or more ubiquinones (Q9, Q10, Q11, Q12, Q13) which were useful for placing the species into one of three distinct groups. Group 1 contained L. longbeachae, L. bozemanii, L. dumoffi, and L. gormanii; group 2 contained only...
متن کاملIsoprenoid quinones in the classification of coryneform and related bacteria.
Menaquinones were the only isoprenoid quinones found in 85 of the 95 coryneform bacteria examined. Dihydromenaquinones having nine isoprene units were the main components isolated from Corynebacterium bovis, from other glutamic acid-producing strains, and from Arthrobacter globiformis and related species. Dihydromenaquinones with eight isoprene units were found in Brevibacterium linens, the rem...
متن کاملIdentification of Carotenoids and Isoprenoid Quinones from Asaia lannensis and Asaia bogorensis.
The aim of the study was to identify and quantitatively assess of carotenoids and isoprenoid quinones biosynthesized by six different strains of acetic acid bacteria, belonging to genus Asaia, that are common beverage-spoiling bacteria in Europe. Bacterial cultures were conducted in a laboratory liquid culture minimal medium with 2% sucrose. Carotenoids and isoprenoid quinones were investigated...
متن کاملThe nature, intergeneric distribution and biosynthesis of isoprenoid quinones and phenols in gram-negative bacteria.
1. Twenty-two aerobically grown Gram-negative bacteria were analysed for demethylmenaquinones, menaquinones, 2-polyprenylphenols, 6-methoxy-2-polyprenylphenols and ubiquinones. 2. All the eight enterobacteria and both the two facultative organisms (Aeromonas punctata and Aeromonas hydrophila) examined contain all the compounds listed above. The principal homologues are octaprenyl; in addition l...
متن کاملThe determination of tocopherols and isoprenoid quinones in the grain and seedlings of wheat (Triticum vulgare).
1. A comparison is made of several procedures for the extraction of tocopherols and isoprenoid quinones from plant tissues. 2. Gradient-elution column chromatography on acid-washed alumina efficiently separates the isoprenoid quinones and tocopherols into groups that can then be assayed spectrophotometrically or, with the tocopherols, separated into their individual components and determined by...
