From: Insights into the Geobacillus stearothermophilus species based on phylogenomic principles
Core genome sequence comparisons. The phylogenetic networks were generated using the Neighbor-Net algorithm in SplitsTree (v. 4.13.1). The orthologous groups were defined using the program OrthoMCL (v. 2.0.9) and the analyses were based on those genes that have orthologous gene members with a length range less than or equal to 20%. Those groups marked with an asterisk contain a strain(s) that originate from a dairy environment. a.
