“…In addition, probiotic feeding of P. xylanexedens , which secretes enzymes such as D-cellulose, D-fructose, D-galactose, α-D-glucose, lactose, and maltose as actively as Bacillus species, improved the BW gain and FCR in broilers under normal feeding environment [ 17 ] or challenged conditions [ 18 ]. Similarly, P. konkukensis , isolated and analyzed for complete genome sequence in our previous studies, has DNA sequences encoding various types of enzymes such as β-glucosidase, cellulase, xylanase, and protease, which can degrade various carbohydrates and anti-nutritional factors [ 23 , 24 ]. However, in this study, P. konkukensis had no measured effects on the growth parameters.…”
