Use of sweet potato residues as carbon source for the growth of xylanase-producing Cellulosimicrobium sp.

Abstract

Forty percent of total sweet potato (Ipomoea batatas L.) root (SPR) production is discarded due to be outfit of the quality control parameter for marketing in northwest region of Buenos Aires province, Argentina. Therefore, local producers face a challege to pormote the use of SPR residues by producing a value-added product. In this way, SPR could be a promising alternative carbon source to formulate culture medium for growing microorganisms capable of metabolising starch. The aim of this study is to evaluate the growth of Cellulosimicrobium sp. CO1A1 strain using different varieties of sweet potato roots as a carbon source. Cellulosimicrobium sp. was reported to be able to use starch as a carbon and to produce xylanase. Xylanases are applied in several food industry processes.
