芽胞杆菌系统分类研究最新进展

刘波等在"芽胞杆菌属及其近源属种名目录"中整理了截至2014年12月底已报道的芽胞杆菌种类,共计多达71属752种,但是,只收录了属名带"bacillus"词尾的5个科的相关属、种。在此基础上,本文对芽胞杆菌系统分类进行了扩展、补充和更新,突出了2015-2016年的最新研究进展:(1)整理了能形成芽胞并且带"bacillus"词尾的各属已报道的种的数量、分类地位变动情况、2015-2016年新发表的种类等;(2)补充了7科中能形成芽胞但是无"bacillus"词尾的属的分类情况;(3)整理了带"bacillus"词尾但不属于芽胞杆菌的属的分类地位。截至2016年12月底,芽胞杆菌目至少包括8科,即芽胞杆菌科(69属604种)、脂环酸芽胞杆菌科(6属46种)、类芽胞杆菌科(10属321种)、巴斯德代柄菌科(1属4种)、动球菌科(15属49种)、芽胞乳杆菌科(6属20种)、嗜热放线菌科(17属36种)和1个待建立的科(1属2种)。其中,有13个属的种类不能形成芽胞。因此,芽胞杆菌目中能形成芽胞的种类,共计8科,112属,1 078种。

Recent Advancements in Taxonomy of Bacillus-like Bacteria: An Updated Review in 2016

In the paper authored by Liu et al.that entitled,"List of species names for the Bacillus-like bacteria",the Bacillus-like bacteria were collated up to the end of December 2014.It included 71 genera and 752 species with only those contained a suffix "bacillus".This article updated the taxonomic information on the Bacillus-like bacteria to include (1) the species number,changes in systematic status,and new species reported in 2015-2016 on each genus with the suffix "bacillus";(2) the progress on taxonomy of the spore-forming genera without the suffix "bacillus" in 7 families,and (3) the classification of the non-Bacillus-like genera with a suffix "bacillus".By yearend 2016,at least 8 families were included in the order of Bacillales.They were Bacillaceae (69 genera and 604 species),Alicyclobacillaceae (6 genera and 46 species),Paenibacillaceae (10 genera and 321 species),Pasteuriaceae (1 genera and 4 species),Planococcaceae (15 genera and 49 species),Sporolactobacillaceae (6 genera and 20 species),Thermoactinomycetaceae (17 genera and 36 species),and an unestablished family (1 genus and 2 species).Among them,the species in 13 genera were not endospore-forming bacteria.Therefore the total number of the sporeforming Bacillus like bacteria reached up to 1 078 species and 112 genera within 8 families.
