【 摘 要 】

Dental plaque samples collected from monkeys (Macaca mulatta) were found to contain a large amount of dissolved methane gas (0.6 nmol CH₄/mg wet wt plaque). Enrichment cultures inoculated with dental plaque obtained from Macaca fascicularis produced methane when the medium contained ethanol, methanol, lactate, acetate or a hydrogen + CO₂ atmosphere. Methane formation in the enrichments was inhibited by oxidation of the culture medium, autoclaving or the addition of 2-bromoethane sulfonic acid (BES). The methane producing enrichments were observed to contain fluorescent cocci occurring singly and in short chains. It was concluded that methane formation in the monkey dental plaque was the result of the presence of methanogenic bacteria.
