“…The quinone analysis demonstrates that microorganisms containing Q-8, Q-9 and Q-10 were the major constituents of the microbiota at the early stage of acclimation, whereas those with partially hydrogenated menaquinones became predominant at the fully acclimated stage. According to the available information on microbial quinone systems (Collins and Jones, 1981;Yokota et al, 1992;Hiraishi, 1999b), the three major species of ubiquinones detected are possibly derived from Alphaproteobacteria, Betaproteobacteria and Gammaproteobacteria. Some portions of the Q-9 and Q-10 contents in addition to Q-10(H 2 ) might be originated from yeasts and fungi (Kuraishi et al, 1991).…”

“…Reactor A and 8 week-operated reactor B produced similar quinone patterns to each other profiled by high proportions of partially saturated menaquinones with MK-8(H 2 ) predominating. Considering the content of higher menaquinone homologues ( n ≥ 8) and partially saturated menaquinones, which have been shown to occur mainly in Actinobacteria (Collins and Jones, 1981;Hiraishi, 1999b), members of this phylogenetic group appeared to constitute at least 60% of the total population in the fully acclimated reactors.…”

Microbial community changes during start-up operation of flowerpot-using fed-batch reactors for composting of household biowaste were studied by quinone profiling, rRNA-targeted fluorescence in situ hybridization (FISH) and cultivation methods. Total and plate counts of bacteria and quinone contents in the reactors increased sharply with time during the start-up period. These increase patterns had two phases; the first increase occurred during 3-4 weeks from the start of waste loading and the second increase was found during the subsequent 4 weeks. The microbial biomass was temporally reduced between the two succession phases. Ubiquinones predominated at the beginning of operation but decreased sharply with time, whereas partially saturated menaquinones became predominant at the fully acclimated stage. These data indicated that the major constituents of microbial populations changed from ubiquinone-containing Proteobacteria to Actinobacteria during the period of operation. Neighbour-joining dendrograms constructed based on the quinone profile data suggested that at least one month is required to establish a stable community structure with the Actinobacteria predominating. The characteristic population shift in the start-up process was also demonstrated by FISH probing and 16S rDNA sequence comparisons of bacterial strains isolated.

“…Chemotaxonomic studies have demonstrated that the major component of quinone differs among the various bacterial lineages. 5 This nature enables us to estimate the specific bacterial sources of the quinone homologs in environments. Quinone components in the marine sediments and possible quinone sources are summarized in Table 1.…”

Characterization of depth-related changes and site-specific differences of microbial communities in marine sediments using quinone profiles

et al. 2005

Respiratory quinone compositions were analyzed by a high-performance liquid chromatography to characterize the depth-related changes and site-specific differences of microbial communities in marine sediments. Two deep-sea sediment samples and one coastal sediment sample were investigated from three sites on the coast of Japan, Sagami Bay, Suruga Bay and Tokyo Bay. Although depth-related changes in microbial community structures were observed, site-specific differences appeared to have greater influence on overall community structures. A variety of quinone homologs was commonly identified at all sampling sites and depths examined, but a few minor quinone fractions, mainly derived from Actinobacteria , were detected only at specific sampling sites. Methylmenaquinone-7 (MMK-7) was the major component throughout the examined depths in Sagami Bay and Tokyo Bay. Most abundant quinone homologs changed with each depth in Suruga Bay. Menaquinone-6 (MK-6) predominated in the 0 to 2-cm layer (19%). Below 0-2 cm, the most abundant homolog in each sampling depth was phylloquinone (K 1 ; 13%, 4-6 cm), [8][9][10] and MK-7 (13%, 16-18 cm). The microbial respiratory quinone profiling method shown here, successfully demonstrates the usefulness of this approach to characterize microbial communities in marine sediments.

“…This menaquinone is thus probably the physiological electron acceptor for F,,,,H, oxidation in the membrane fraction of A. jufgidus. Yagi et al (1988) reported the isolation of two Feperate membrane-bound NADH :quinone oxidoreductases from the thermophilic (eu)bacterium Thermus thermophilus strain HB-8, an organism containing only menaquinone (Collins and Jones, 1981). NADH dehydrogenase I, considered to represent an energy coupling site (Meinhardt et al, 1990), is composed of at least ten different polypeptides which contain 10-12 mol non-heme iron, 10-12 mol acid-labile sulfur and 1 mol non-covalently bound FMN.…”

Archaeoglobus fulgidus, a hyperthermophilic sulfate-reducing archaeon, was found to contain a membrane-bound F42JI2 : quinone oxidoreductase complex presumed to be involved in energy conservation during growth on lactate plus sulfate. After solubilization with dodecyl-/I-D-maltoside the complex was purified 32-fold with a yield of 24%. Using both gel filtration and native PAGE, an apparent molecular mass of approximately 270 kDa was determined. SDSPAGE revealed the presence of at least seven polypeptides with apparent molecular masses 56, 45, 41, 39, 37, 33, and 32 kDa. The purified complex contained 1.6 mol FAD, 9 mol non-heme iron and 7 mol acid-labile sulfur/mol complex. It did not contain cytochromes, which were, however, present in the membrane fraction of A. fulgidus (3 nmoVmg membrane protein). The purified F42& : quinone oxidoreductase complex catalyzed the reduction of 2,3-dimethyl-l,4-naphthoquinone (apparent K, 190 pM) with reduced coenzyme F420 (apparent K, 50 pM) exhibiting a specific activity of 500 U/mg (apparent VmJ at pH 8.0 (pH optimum) and 65 "C (temperature optimum). 2-Methyl-l,4-naphthoquinone (menadione), 2-hydroxy-l,4-naphthoquinone, 1,4-naphthoquinone, 2,3-dimethoxy-5-methyl-l,4-benzoquinone, and 2,3-dimethoxy-5-methyl-6-decyl-1,4-benzoquinone (decyl-ubiquinone) were also reduced with F,,,H,, albeit with lower rates. The physiological electron acceptor of the F4,aZ : quinone oxidoreductase complex is most likely the menaquinone found in the membrane fraction of A. fulgidus.
