A yellow-pigmented, Gram-negative, rod-shaped, strictly aerobic bacterium (strain UST050418-085(T)) was isolated from the surface of a marine sponge, Myxilla incrustans, at Friday Harbor, WA, USA. The DNA G+C content of this strain was 34.6 mol%. The predominant fatty acids were i15 : 0, a15 : 0, i15 : 1, i16 : 0, i17 : 0 3-OH, 17 : 0 2-OH and summed feature 3, comprising i15 : 0 2-OH and/or 16 : 1omega7c (altogether representing 69.0 % of the total fatty acids). MK-6 was the only respiratory quinone detected. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the closest relatives of UST050418-085(T) were members of the genus Gillisia, with sequence similarities of 93.2-96.6 %. Strain UST050418-085(T) differed from its closest relatives by 11 to 18 phenotypic traits. Molecular evidence and phenotypic characteristics suggest that strain UST050418-085(T) represents a novel species within the genus Gillisia. The name Gillisia myxillae sp. nov. is proposed, with UST050418-085(T) (=JCM 13564(T)=NRRL B-41416(T)) [corrected] as the type strain.
从美国华盛顿州星期五港的一种海洋海绵——硬壳粘管海绵（Myxilla incrustans）表面分离出一株黄色色素沉着、革兰氏阴性、杆状、严格需氧的细菌（菌株UST050418-085(T)）。该菌株的DNA G+C含量为34.6 mol%。主要脂肪酸为i15 : 0、a15 : 0、i15 : 1、i16 : 0、i17 : 0 3-OH、17 : 0 2-OH以及特征性脂肪酸总和3，后者由i15 : 0 2-OH和/或16 : 1ω7c组成（总共占总脂肪酸的69.0%）。检测到的唯一呼吸醌为MK-6。基于16S rRNA基因序列的系统发育分析表明，UST050418-085(T)最接近的亲缘种是吉利氏菌属（Gillisia）的成员，序列相似性为93.2 - 96.6%。菌株UST050418-085(T)与其最接近的亲缘种在11至18个表型特征上存在差异。分子证据和表型特征表明，菌株UST050418-085(T)代表吉利氏菌属内的一个新物种。提议将其命名为粘管海绵吉利氏菌（Gillisia myxillae）新种，以UST050418-085(T)（=JCM 13564(T)=NRRL B-41416(T)）[已校正]作为模式菌株。
