  • Cognaticolwellia mytili (Kim et al. 2017) Liu et al. 2021[2][3]

贻贝科维尔氏菌（学名：Colwellia mytili）是科尔韦氏菌属的下属物种。[1]此物种是一种革兰氏阴性、过氧化氢酶阳性、氧化酶阳性且耐冷（也可以是嗜温）的杆状细菌。[4]此物种最早从韩国南海采集的紫贻贝（Mytilus edulis）中分离出来。[5]

历史

贻贝科维尔氏菌的模式菌株RA2-7T最早从韩国南海采集的紫贻贝（Mytilus edulis）中分离出来。在2021年，Liu等人建议将该物种重新分类为一个新属，命名为Cognaticolwellia mytili 。尽管根据ICNP标准有效发布，Cognaticolwellia mytili目前仍然只是Colwellia mytili的同义词。[5][2][3]

词源

新拉丁属格阳性名词“mytili”，指贻贝属（mytilus），表示以紫贻贝的属名命名，贻贝科维尔氏菌的模式菌株也是从中分离出来的。[1]

系统发育学分类

基于16S rRNA基因序列的系统发育分析表明菌株RA2-7T属于科尔韦氏菌属。菌株RA2-7T与海岸沉积物科维尔氏菌、潮滩科维尔氏菌和极地科维尔氏菌等的模式菌株的16S rRNA基因序列相似度分别为98.3%、98.0%和97.5%。菌株RA2-7T与其他科尔韦氏菌属的物种的16S rRNA基因序列相似性值为94.5至96.5%。[5]

描述

贻贝科维尔氏菌是一种需氧、不形成孢子的革兰氏阴性菌。它能够在4°C至25°C（最佳20℃，但不生长在高于28°C的环境）、pH6（最佳pH7至pH8，但不生长在低于pH5.5的环境）和1.5%至4.0%NaCl（最佳2%至3%）的条件下生长，因此它是一种耐冷（也可以是嗜温）、中性且耐盐的生物。它的细胞是杆状的，长0.5µm至8µm，宽0.3µm至0.7µm，用单极鞭毛运动。它的过氧化氢酶和氧化酶测试呈阳性。在20℃的海洋琼脂上培养5天后，菌落呈圆形，微凸，有光泽，光滑，灰黄色，大小为0.8至1.5毫米。[4][5]

Hewan jinak

Di taman publik, beberapa hewan liar, seperti tupai abu-abu timur ini, telah cukup jinak sehingga kehilangan rasa takut alaminya kepada manusia. Hewan jinak adalah hewan yang relatif toleran dengan keberadaan manusia. Kejinakan dapat muncul secara alami (misalnya pada kasus kejinakan pulau) atau karena proses pelatihan hewan yang disengaja dan diarahkan oleh manusia sehingga hewan tersebut melawan naluri awalnya yang liar atau alami untuk menghindari atau menyerang manusia.
