Abstract: The objective of this work was to look at the effects agitation and growth times on the properties of bacterial cellulose produced by Gluconacetobacter xylinus. Gluconacetobacter xylinus was grown in HS medium at 50 rpm at room temperature for effect agitation and 23oC, 25oC, 27oC and 30 oC at static conditions for seven days. The cellulose produced was analyzed for crystallinity index, FTIR, SEM. The results showed The use of agitation and decreasing temperature can reduce the index crystallinity of bacterial cellulose, and shown by evidence of changes in hydrogen bonding. Decreasing crystallinity index of bacterial cellulose furthermore resulted in more void and loose cellulose arrangement.
