Phylogeny and codon usage bias of bacterial genomes in <i>Bifidobacterium animalis</i>

In nature, the phenomenon of an equal probability distribution four nucleotides did not exist. Due to influence selection, Bifidobacterium animalis would be presented with probability. was frequently added food because its special metabolic pathway, which could catalyze fructose and lactic acid. This study analyzed industrial environmental through strategies such as a phylogenetic tree, ENC, RSCU, PR2, neutral graph, ENC top/bottom gene enrichment graph. The result that whole is greatly affected by environment, while difference between internal bacteria apparent. provide reference for screening strains from further development .
