| Popis: | Rayon filaments composed of regenerated cellulose are used as reinforcement materials in tires and to a lower extent in the clothing industry as personal protective equipment e.g. flame retardant cellulosic based materials. After use, these materials are currently transferred to landfills while chemical degradation does not allow the recovery of the cellulose (as glucose) nor the separation of the high valuable flame-retardant pigment. In this study, rayon fibers were enzymatically hydrolyzed to allow recovery of glucose and valuable additives. The glucose was successfully used as carbon source for the production of high value compounds such as itaconic acid, lactic acid and chitosan. 14.2 g/L of itaconic acid, 36.5 g/L of lactic acid and 39.2 g/L of chitosan containing biomass were produced from Escherichia coli, Lactobacillus paracasei and Aspergillus niger, respectively, comparable to yields obtained when using commercial glucose as carbon source. |
