“…(1998), except that 5 g samples were used for quinone extraction and post-run analysis of the data was performed according to the Shimadzu CLASS-VP V5.032 program (Shimadzu, Kyoto, Japan). The menaquinones and ubiquinones were expressed in an abbreviated form, namely MK and Q, followed after a hyphen by the number of isoprenoid units and the number of hydrogen atoms in the hydrogenation of double bonds in the side chains (Katayama and Fujie 2000). The quinone species were identified based on the retention time and UV absorption spectrum, and sometimes LC / MS was used to confirm the results.…”

“…Because most of the microorganisms contain one species of quinone as their major quinone (Katayama and Fujie 2000), the quinone profiles are considered to reflect the microbial community structure in the composts. It is assumed that ubiquinones were derived from Proteobacteria species and fungi, lower homologues of menaquinones (::::::MK-8) from Gram-positive bacteria with low G + C contents and other phylogenetic groups of bacteria, and menaquinones with partially saturated and long sidechains (:::::MK-9) from Actinobacteria species (Grampositive bacteria with high G + C contents) (Hiraishi et al 2000).…”

Microbial community succession and lignocellulose degradation during agricultural waste composting

The changes of microbial community during agricultural waste composting were successfully studied by quinone profiles. Mesophilic bacteria indicated by MK-7 and mesophilic fungi containing Q-9 as major quinone were predominant and seemed to be important during the initial stage of composting. Actinobacteria indicated by a series of partially saturated and long-chain menaquinones were preponderant during the thermophilic period. While Actinobacteria, fungi and some bacteria, especially those microbes containing MK-7(H4) found in Gram-positive bacteria with a low G+C content or Actinobacteria were found cooperate during the latter maturating period. Since lignocellulose is abundant in the agricultural wastes and its degradation is essential for the operation of composting, it's important to establish the correlation between the quinone profiles changes and lignocellulose degradation. The microbes containing Q-9 or Q-10(H2) as major quinone were found to be the most important hemicellulose and cellulose degrading microorganisms during composting. While the microorganisms containing Q-9(H2) as major quinone and many thermophilic Actinobacteria were believed to be responsible for lignin degradation during agricultural waste composting.

A total of 11 sediment samples were collected from the sites along Haihe River-Bohai Bay, with site 1 at the beginning of Haihe River and site 11 in Bohai Bay, about 150 km away from site 1. Quinone profiles were used for the analysis of microbial community as influenced by pollutants in water and sediments, such as heavy metals, and other environmental factors. Nineteen species of quinones were found at site 1 while only six species at sites 10 and 11. Both the diversity of quinone species (DQ) and the number of quinones were higher in the sediments from Haihe River and the near-sea area of Bohai Bay than in those from the deep-sea area. The β diversity values were significantly higher, while Jaccard indexes of similarity were much lower among non-contiguous pairs of sites as compared with the contiguous ones. Cluster analysis indicated that quinone profiles may be grouped into two main clusters (sites 1-7 and sites 8-11), and there were higher similarities within the groups than between groups. Quinone species composition varied at different sites. Ubiquinones such as UQ-8, UQ-9, and UQ-10 and menaquinones such as MK-6, MK-7, MK-8 were isolated from all the sites and accounted for the largest proportions. Pearson correlation analysis revealed that both the number of quinone species and DQ correlated positively with total organic carbon contents in water and sediments, but negatively correlated with salinity and electroconductivity and did not correlate significantly with heavy metal contents in water.
