Isolation, modification and characterisation of cellulose from wild Dioscorea bulbifera

Abstract This study attempted to valorise wild Dioscorea bulbifera yam presently known to be poisonous and inedible obtained from three sources. The functional properties as well as its chemical composition were determined and isolated. Isolated cellulose was modified by the actions of sodium hydrox...
