Detailed methods: MALDI-TOF and FAME profile analysis; dendrogram demonstrating strain relatedness revealed by MALDI-TOF analysis (Fig. S1); dendrogram demonstrating the relatedness of fatty acid compositions in B. humptydooensis sp. nov. and closely related species (Fig. S2); 16S maximum-likelihood phylogeny using both copies of the 16S rRNA gene from each B. humptydooensis sp. nov. strain (Fig. S3); maximum-likelihood phylogeny of the recA sequence using 193 sequences (Fig. S4).
