从南极红雪中分离到一株新的好氧细菌P3 T。P3 T细胞呈杆状，不运动，过氧化氢酶阴性，氧化酶阳性，革兰氏染色阴性。在0至25 °C的温度范围内观察到生长，在15 °C下生长最佳。生长的pH范围为pH 5.3-7.8。基因组DNA的G+C含量为55.0mol%。脂肪酸谱中的主要组分为异-C15：0、总特征4（异-C17：1 I和/或反异-C17：1 B）、反异-C15：0和总特征3（异-C16：1ω 7 c和/或异-C16：1ω 6 c）。主要的类异戊二烯醌是MK-7。基于16 S rRNA基因序列的系统发育分析表明，该菌株属于膜壳菌属，与冰川沙门氏菌VUG-A130 T，膜壳菌同源性最高（94%）。soli PB 17 T和Hymenoprotein.南五味子VUG-A42 aaT.基于系统发育和表型特性，菌株P3 T代表膜壳属的一个新种（建议将其命名为膜壳属新种（Hymenopyrinavis sp. nov.））。模式菌株为P3 T（=DSM 101755 T =NBRC 111535 T）。
A novel aerobic bacterial strain, P3T, was isolated from a red snow obtained from Antarctica. Cells of strain P3T were rod-shaped, non-motile, catalase-negative, oxidase-positive and Gram-stain-negative. Growth was observed at temperatures ranging from 0 to 25 °C, with optimum growth at 15 °C. The pH range for growth was pH 5.3-7.8. The G+C content of the genomic DNA was 55.0 mol%. The major components in the fatty acid profile were iso-C15 : 0, summed feature 4 (iso-C17 : 1 I and/or anteiso-C17 : 1 B), anteiso-C15 : 0 and summed feature 3 (iso-C16 : 1ω7c and/or iso-C16 : 1ω6c). The predominant isoprenoid quinone was MK-7. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the novel isolate was a member of the genus Hymenobacter, and the strain showed highest sequence similarity (94 %) with H.ymenpbacter glaciei VUG-A130T, Hymenobacter. soli PB17T and Hymenobacter. antarcticus VUG-A42aaT. On the basis of phylogenetic and phenotypic properties strain P3T represents a novel species of the genus Hymenobacter (for which the name Hymenobacter nivis sp. nov. is proposed. The types strain is P3T (=DSM 101755T=NBRC 111535T).
