Phylogenetics of newly identified potential clostridial probiotics and growth inhibition of Clostridium perfringens by these probiotic bacteria. A 16S rRNA-based phylogeny of newly-isolated clostridia based on maximum-likelihood phylogenetic reconstruction of full-length (>1400 bp) 16S rRNA gene sequences. Taxa shown in red represent axenic cultures with representative nearest cultured isolates from v115 of the Silva database shown in black. Numbers after taxa represent % identity to closest cultured representative as determined by global usearch against a comprehensive reference database. Approximately 15 strains most closely related to Bacillus spp. were also isolated as indicated by the collapsed clade at the bottom of the figure. B Growth inhibition of C. perfringens by strains c2-6 and c1-8 (shown with arrows) demonstrated anti-microbial properties when placed on a lawn of C. perfringens. The mechanisms causing the underlying this phenomenon are still unknown.
