Sugar Cane Glycoproteins: an Alternative to Improve the Production of Xanthan Gum by Xanthomonas albilineans

Abstract

Xanthomonas albilineans, although it is an essential phytopathogen for sugar cane, is capable of producing xanthangum (XG). This macromolecule is used in the food, pharmaceutical, and gas production industries, but its production is expensivewhen considering the substrate and its purity. On the other hand, the possibility of using the material for disposal, such as theinfected sugar cane stalk, can be attractive since this substrate can produce XG and has no value for cultivation. Thus, we describethe possibility of its production in different culture media using immobilized cells from sugar cane stalk tissues supplemented withglycoproteins or sucrose. Using molecular patterns associated with bacterial pathogens (PAMPs), the presence of gum in isopropylalcohol precipitate is obtained after incubation and culture improvement. This production model describes a new possibility of gumproduction, contributing to the potential for sustainability and diversification of the sugar cane industry
