Application of sweet potato root (SRP) residues as an alternative carbon source to formulate a culture medium for the growth of xylanase-producing microorganisms, is presented in this article. Six commercial varieties of SPR were tested for evaluating the growth of Cellulosimicrobium sp. CO1A strain in shaken flask cultures. Results showed that Cellulosimicrobium sp. CO1A1 was able to grow in a medium formulated with SPR. Biomass estimated by optical density was the most appropriate method for the medium evaluated. Additionally, biomass did not show significant differences (p>0.05) between commercial varieties of SPR, being between 8.12 and 9.26 of OD. All the varieties of RPS tested in this work are equally promising source to be applied in a bioprocess to obtain xylanase by Cellulosimicrobium sp. CO1A1.
