The use of modest doses of gamma radiation to produce Bacterial Nano cellulose has reached a tipping point.

John Wilson

Due to its wonderful qualities and wide range of uses, enormous efforts have been made in recent years to devise a cost-effective production procedure for Bacterial Nano cellulose (BNC). The influence of gamma irradiation on BNC yield was investigated using a new bacterial strain, Komagataeibacter hansenii KO28, which was treated to various irradiation doses using a devised scheme, and the productivity and structural features of the BNC were examined. After 240 hours of incubation, the culture treated twice with 0.5 kGy had the greatest BNC yield, which was 475 percent greater than the contr- -ol culture. Furthermore, the first six days produced about 92 percent of the BNC yield. SEM, Thermogravimetric Analysis (TGA), X-Ray Diffraction (XRD), and Fourier transform infrared spectroscopy were used to evaluate the physicochemical properties of BNCs (FTIR). For the BNC formed from the control and irradiation cultures, the water retention capacity, water release rate, surface area (BET), and mechanical characteristics were also adjusted. Overall, there were no significant differences in the characteristics of the BNC generated by the irradiated cultures compared to the control, suggesting that strain irradiation might be a useful, simple, and inexpensive way to increase BNC output
