<i>Psychrosphaera algicola</i> sp. nov. and <i>Paraglaciecola algarum</i> sp. nov., and reclassification of <i>Pseudoalteromonas elyakovii</i>, <i>Pseudoalteromonas flavipulchra</i>, and <i>Pseudoalteromonas profundi</i> as later heterotypic synonyms of <i>P. distincta</i>, <i>P. maricaloris</i>, and <i>P. gelatinilytica</i>.

ABSTRACT: Two Gram-negative, obligately aerobic, rod-shaped bacteria, strains G1-22^T and G1-23^T, were isolated from the phycosphere of a marine brown alga. Both strains exhibited catalase- and oxidase-positive activities. Strain G1-22^T displayed optimal growth at 25 °C, pH 8.0, and 2.0-3.0% (w/v) NaCl, while strain G1-23^T exhibited optimal growth at 25 °C, pH 8.0, and 4.0% NaCl. Ubiquinone-8 was identified as the sole isoprenoid quinone in both strains. As major fatty acids (> 5%), strain G1-22^T contained C_16 : 0, summed feature 3 (C_16 : 1 ω7c and/or C_16 : 1 ω6c), summed feature 8 (C_18 : 1 ω7c and/or C_18 : 1 ω6c), C_12 : 1 3-O
