“…On the other hand, the second degradation step for BC/CMC/Gly/yeast started between 240 °C to 260 °C and continued until 330 °C when cellulose chains were broken, which resulted in a 75% weight loss. Studies have shown that the main BC cellulose skeleton degrades up to 300 °C [ 65 , 73 ]. These results show that the addition of Gly and yeast slightly reduced the thermal degradation behaviors of the composite film, thus indicating the improved thermal stability of BC at elevated temperature, which is useful for the sterilization of packaging material.…”

The unique properties and advantages of edible films over conventional food packaging have led the way to their extensive exploration in recent years. Moreover, the incorporation of bioactive components during their production has further enhanced the intrinsic features of packaging materials. This study was aimed to develop edible and bioactive food packaging films comprising yeast incorporated into bacterial cellulose (BC) in conjunction with carboxymethyl cellulose (CMC) and glycerol (Gly) to extend the shelf life of packaged food materials. First, yeast biomass and BC hydrogels were produced by Meyerozyma guilliermondii (MT502203.1) and Gluconacetobacter xylinus (ATCC53582), respectively, and then the films were developed ex situ by mixing 30 wt.% CMC, 30 wt.% Gly, 2 wt.% yeast dry biomass, and 2 wt.% BC slurry. FE-SEM observation showed the successful incorporation of Gly and yeast into the fibrous cellulose matrix. FTIR spectroscopy confirmed the development of composite films through chemical interaction between BC, CMC, Gly, and yeast. The developed BC/CMC/Gly/yeast composite films showed high water solubility (42.86%). The yeast-incorporated films showed antimicrobial activities against three microbial strains, including Escherichia coli, Pseudomonas aeruginosa, and Saccharomyces aureus, by producing clear inhibition zones of 16 mm, 10 mm, and 15 mm, respectively, after 24 h. Moreover, the films were non-toxic against NIH-3T3 fibroblast cells. Finally, the coating of oranges and tomatoes with BC/CMC/Gly/yeast composites enhanced the shelf life at different storage temperatures. The BC/CMC/Gly/yeast composite film-coated oranges and tomatoes demonstrated acceptable sensory features such as odor and color, not only at 6 °C but also at room temperature and further elevated temperatures at 30 °C and 40 °C for up to two weeks. The findings of this study indicate that the developed BC/CMC/Gly/yeast composite films could be used as edible packaging material with high nutritional value and distinctive properties related to the film component, which would provide protection to foods and extend their shelf life, and thus could find applications in the food industry.

“…The thermogravimetric curves further reflect the areas of weight loss. The thermal degradation behavior also explains the fibrillation characteristics of BC and its purity, as indicated by the absence of any further degradation areas [ 73 , 74 ].…”

“…BC has advantages among other cellulose in mechanical strength, crystallinity, nanofibril structure, purity, and biocompatibility [59]. BC has the potential to be used in biomedical [59], audio membrane [60], electronic paper [61], and biocomposites [22,62]. With this many potentials, it does not close the possibility of using BC as an environmentally friendly scrubber.…”

“…Bacterial cellulose has ultra-fine fibrils and it has superior properties compared to plant cellulose [68]. Based on these advantages, bacterial cellulose is widely used in various medical applications [59], membrane [60], film-coating agent [69], biofilm, composite material [22,[70][71][72][73], and paper [61]. Bacterial cellulose can be used as a substitute for microplastic in scrubbers in the form of microparticles.…”

Scrubber is widely used in various products, such as cosmetics, facial cleansers, and soaps. The use of scrubber releasing 209.7 trillion microplastics would harm the environment due to lack of process in treatment facilities. Efforts to substitute plastic-based scrubbers with more environmentally friendly materials need to be made. In previous studies, substitution scrubber with grape seeds has been done but has a low viscosity. This problem may be solved by using bacterial cellulose (BC) in the manufacture of bio-scrubbers. Several methods are currently being investigated to produce bacterial cellulose microparticles, such as mechanical methods using high-pressure homogenizer (HPH), acid hydrolysis, microbial hydrolysis, hydrogel fiber cultivation, microfluidic process, and ultrasonication. This review recommends the manufacture of bacterial cellulose microparticles by ultrasonication method. The recommendation is based on the literature study that has been carried out. The ultrasonication method has more advantages than other methods. It does not use solvents that pollute the environment and increasing the number of bacterial cellulose microparticles. The synthesis of bio-scrubber from bacterial cellulose ends with the drying process of bacterial cellulose microparticles. This review recommends the ambient pressure drying method. The ambient pressure drying method can produce bio-scrubber with high crystallinity, high mechanical properties, and transparency.
