<i>Pontibacter rufus</i> sp. nov., <i>Pontibacter humidus</i> sp. nov. and <i>Pontibacter coccineus</i> sp. nov. isolated from UV-irradiated soil in Korea.

ABSTRACT: Three novel bacterial strains, 172403-2^T, BT310^T and BT731^T, were isolated from UV-irradiated soil samples collected in South Korea. All strains are Gram-negative, aerobic, non-motile and grow at 20-35 °C, optimally at 30 °C and pH 7.0. The optimal NaCl concentration for strains 172403-2^T and BT310^T is 1.5%, while strain BT731^T grows optimally in the absence of NaCl (0.0%). Phylogenetic analysis based on 16S rRNA gene sequences positioned these strains within the genus Pontibacter, with strain 172403-2^T closest to Pontibacter chitinilyticus (95.96%), BT310^T to Pontibacter pudoricolor (97.87%) and BT731^T to Pontibacter virosus (98.06%).
