( 2009 ) Re-examination of the taxonomic position of Bacillus silvestris Rheims et al. 1999 and proposal to transfer it to Solibacillus gen. nov. as Solibacillus silvestris comb. nov. PMID : 19406792 DOI : 10.1099/ijs.0.65742-0 Abstract >>
Following the transfer of three of the six species enclosed in the original definition of rRNA group 2 of Bacillus to the genus Sporosarcina and two to Lysinibacillus, other species of this group, some of which were added later, still await taxonomic revision. In a recent publication, a set of 'core' characteristics was proposed for species to be included in the genus Bacillus (K?mpfer et al., 2006). Except for Bacillus silvestris, however, several or none of these properties are available for members of rRNA group 2. According to our analysis of data including the 'core' characteristics, Bacillus silvestris should not be a member of the genus Bacillus. We therefore propose the establishment of a new genus, Solibacillus gen. nov., and transfer Bacillus silvestris to this genus as Solibacillus silvestris comb. nov., with the type strain HR3-23(T) (=DSM 12223(T)=ATCC BAA-269(T)=CIP 106059(T)).

( 1999 ) Bacillus silvestris sp. nov., a new member of the genus Bacillus that contains lysine in its cell wall. PMID : 10319505 DOI : 10.1099/00207713-49-2-795 Abstract >>
A Gram-positive, aerobic, rod-shaped, peritrichously flagellated, round-endospore-forming bacterium was isolated from a forest soil near Braunschweig, Lower Saxony, Germany, and designated strain HR3-23T (T = type strain). Morphologically, strain HR3-23T shows the characteristics of a member of the genus Bacillus. The spore position is terminal in a swollen sporangium. Comparative analysis of the 16S rDNA sequence shows strain HR3-23T to be most closely related to Caryophanon tenue (95.8% 16S rRNA similarity) and to Bacillus sphaericus (95.4% 16S rRNA similarity). Phylogenetically, the isolate clusters among species of Bacillus RNA group 2. The DNA G + C content of isolate HR3-23T is 39.3 mol%, the peptidoglycan type is A4 alpha (L-Lys-D-Glu), the major respiratory lipoquinone is menaquinone MK-7 and the predominant fatty acid is of the iso-C15:0 type. Based on the morphological, chemotaxonomic, physiological and phylogenetic properties, a new species, Bacillus silvestris, is proposed; strain HR3-23T is the type strain (= DSM 12223T).
