Gut and Environment Bacteria in Bacteroidota

Description

Bacteroidota is a bacterial phylum with more than 700 species. It includes four main orders: Bacteroidales, Cytophagales, Flavobacteriales, and Sphingobacteriales. These bacteria are gram-negative, do not form spores, and are usually rod-shaped. They can be aerobic or fermentative, and some use gliding motility while others ...

拟杆菌门包括革兰氏阴性杆菌,分为四个目——拟杆菌目、细胞噬菌目、黄杆菌目和鞘杆菌目。

拟杆菌目(Bacteroidales)主要由专性厌氧、可发酵的细菌组成。

值得注意的是,拟杆菌属(Bacteroides)构成了人体大肠中微生物生物量的重要部分。

细胞噬菌目(Cytophagales)主要包括专性需氧菌,通常为细长杆状,常具有尖端。

Cytophaga 是噬纤维菌目中的一个关键属,能够降解纤维素、琼脂和几丁质。

黄杆菌目(Flavobacteriales)包括广泛分布的黄杆菌属(Flavobacterium),以及嗜极杆菌属(Polaribacter)和嗜冷屈挠杆菌属(...
