Abstract

16S rDNAs amplified by PCR from 22 hyperthermophilic methanococci isolated from deep-sea hydrothermal vents were compared with those of the six type strains of the genus Methanococcus by RFLP analysis. Restriction fragments obtained with Haelli enabied four of the type species to be distinguished. Restrictions with HhaI, BstUI and MspI were necessary to differentiate Methanococcus jannaschii and Methanococcus fervens. The results indicate that the 16S rDNA PCR-RFLP method provides a rapid and reliable tool for the identification of newly isolated hyperthermophilic Methanococcus spp.
