“…It should be noted that kombucha tea is a fermented tea that contains acetic acid bacteria (Komagataeibacter, Gluconacetobacter, and Acetobacter species) and yeasts (Dekkera, Hanseniaspora and Zygosaccharomyces) (Coton et al, 2017;De Roosand De Vuyst, 2018). From this acetic acid bacteria, Li et al (2019), Mohamed et al (2019) and Zhang et al (2018) were able to isolate K. hansenii, Acetobacter pasteurianus and G. xylinus, respectively from kombucha tea for the production of BC. In addition to genetic stability, the micro-optical structure, functional group characteristics of molecular surface, crystallinity and thermal stability of BC were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and thermogravimetric analysis (TG).…”

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.
