“…Furthermore, in the process of BC biosynthesis, bacterium resource, culture medium, fermentation methods and fermentation conditions could also affect the quality of the nal product (Andriani et 2021) presented a novel ex situ modi cation of BC polymer in order to improve its ability to absorb water after drying. However, its production is limited due to single production strain, low genetic stability, low yield of synthesis, and high cost of the culture media is needed industrialization (Quintana-Quirino et al, 2021). Therefore, it is still di cult to meet the needs of the application market for BC materials.…”

The quality control of the bacterial cellulose (BC) production has been facing challenges due to the genetic stability of bacterial strains, which is often overlooked or underestimated. Thus, its commercialized application is limited. Therefore, a bacterial strain FM883 with a 16S rRNA sequence 97% identical to Komagataeibacter xylinus NBRC15237 T was isolated from kombucha tea. Cultivation of FM883 was conducted in series to observe the morphology and BC yield among different generations from 1 st generation to 30 th generation. The results show that FM883 can e ciently produce BC in modi ed Hestrin-Schramn media at the 30 th generation (163.5 ± 0.3 g/L), which was even higher than the 1 st generation (157.6 ± 0.3 g/L). This indicated that FM883 has strong genetic stability. Furthermore, several characterizations of the BC indicated that the quality of the BC biosynthesized by FM883 was good with excellent thermostability. With such strong genetic stability, properties, su ciently high consistency and high yield, BC biosynthesized by FM883 had demonstrated excellent production quality control, which is desired for commercial manufacturing.
