Summary This paper reports on the treatment of Acetobacter xylinum (CGMCC No. 7431) by ultraviolet (UV) to investigate the role of mutagenesis on the production of cellulose. When Acetobacter xylinum was treated at intervals of UV mutagenesis, the treatment times of 3 and 4 min formed more compact bacterial cellulose. The activation conditions, including the medium nutrients that affected the yield of bacterial cellulose, were investigated including the use of coconut milk. The optimal yield of bacterial cellulose was 43.91 ± 3.89 g L −1 , which was 1.22 times higher than that obtained from the wild type without any treatment. The experimental results suggested that different UV factors could significantly affect the yield of bacterial cellulose. The resulting bacterial cellulose has a potential as a novel functional food material.
