A strain of a gram-positive, coccoid, yellow-pigmented bacterium was isolated from human blood. The bacterium was aerobic, non-encapsulated and non-motile. Phenotypically, the bacterium closely resembled Kytococcus sedentarius, but could be distinguished from this species by physiological tests and chemotaxonomic investigations. The peptidoglycan type is L-Lys-Glu2, variation A4alpha. The predominant menaquinones are MK-8 and MK-7. The major cellular fatty acids are iso-C17:1, iso-C17:0, iso-C15:0 and anteiso-C17:0. The strain contains catalase and does not produce acid from carbohydrates. The ability to hydrolyse Tween 80 and the lack of alpha-glucosidase activity are the most characteristic features. The results of comparative 16S rDNA analysis revealed that the strain represents a novel species within the genus Kytococcus, for which the name Kytococcus schroeteri sp. nov. is proposed. The type strain is strain Muenster 2000T (= DSM 13884T = CCM 4918T).
从人血液中分离出一株革兰氏阳性、球状、产黄色色素的细菌。该细菌为需氧菌，无荚膜，无运动性。在表型上，该细菌与久坐不动库克菌极为相似，但可通过生理学试验和化学分类学研究与该物种区分开来。肽聚糖类型为L-Lys-Glu2，变异型A4α。主要的甲基萘醌是MK-8和MK-7。主要的细胞脂肪酸是异-C17:1、异-C17:0、异-C15:0和anteiso-C17:0。该菌株含有过氧化氢酶，不能从碳水化合物中产酸。水解吐温80的能力和缺乏α-葡萄糖苷酶活性是最具特征性的特点。比较16S rDNA分析结果表明，该菌株代表库克菌属内的一个新物种，为此提出了新名称施氏库克菌（Kytococcus schroeteri sp. nov.）。模式菌株是明斯特2000T株（= DSM 13884T = CCM 4918T）。
