A novel Bacillus isolate from raw milk and four strains from diverse origins that were identified previously as Bacillus lentus, Bacillus firmus and Bacillus circulans showed a high degree of similarity in amplified rDNA restriction analysis, SDS-PAGE and routine phenotypic tests, whilst 16S rDNA sequence comparisons and DNA relatedness data showed that this taxon was different from related Bacillus species. On the basis of these data, Bacillus galactosidilyticus sp. nov. is proposed, with the type strain LMG 17892(T) (=DSM 15595(T)=Logan B2188(T)=MB 800(T)).
从生牛奶中分离出的一株新型芽孢杆菌以及先前鉴定为缓慢芽孢杆菌、坚强芽孢杆菌和环状芽孢杆菌的四株来自不同来源的菌株，在扩增核糖体DNA限制性分析、SDS-PAGE和常规表型测试中显示出高度相似性，而16S rDNA序列比较和DNA相关性数据表明，该分类单元与相关芽孢杆菌属物种不同。基于这些数据，提出了半乳糖分解芽孢杆菌新种，模式菌株为LMG 17892(T)（=DSM 15595(T)=Logan B2188(T)=MB 800(T)）。
