“…Despite the static fermentation of cultures being used on laboratory scale with high yield and productivity, it represents a challenge for BC production on industrial scale, since species used for biosynthesis are highly aerobic and generally require high rate of oxygen transfer [124,143]. In this context, airlift fermenters are energy-efficient bioreactors with reduced shear stress; these bioreactors can maintain adequate aerobic conditions without causing major changes in BC structure [144,145].…”

Bacterial cellulose has advantages over plant‐derived cellulose, which make its use for industrial applications easier and more profitable. Its intrinsic properties have been stimulating the global biopolymer market, with strong growth expectations in the coming years. Several bacterial species are capable of producing bacterial cellulose under different culture conditions; in this context, strategies aimed at metabolic engineering and several possibilities of carbon sources have provided opportunities for the bacterial cellulose's biotechnological exploration. In this article, an overview of biosynthesis pathways in different carbon sources for the main producing microorganisms, metabolic flux under different growth conditions, and their influence on the structural and functional characteristics of bacterial cellulose is provided. In addition, the main industrial applications and ways to reduce costs and optimize its production using alternative sources are discussed, contributing to new insights on the exploitation of this biomaterial in the context of the bioeconomy.

“…Many researchers have drawn attention to the development of sustainable biomaterials obtained from renewable sources. Approximately 100–150 billion tons of cellulose are synthesized naturally every year globally, making it one of the most abundant and recognized materials on Earth [ 1 , 2 ]. In addition, cellulose is obtained from plants and recognized for being an organic and biodegradable polymer [ 2 ].…”

“…In 1886, the pioneer researcher Brown described, for the first time, the strain A. xylinum , naming it a ‘vinegar plant’ from the presence of a gelatinous mass on the surface of the culture fluid. In-depth studies have since been carried out to understand cellulose biosynthesis by A. xylinum [ 1 , 6 ].…”

“…The BC produced by kombucha has received a lot of attention due to its excellent mechanical and physicochemical properties, and is exploited for different applications, such as food, textile, and environmental. In addition to its unique physicochemical properties compared to plant cellulose, 79.2 tons of BC in 500,000 L can be produced in only 22 days; while in 1-hectare of land, only 80 tons of cellulose are produced by the plants during 7 years [ 1 , 7 ]. However, the lack of information about the feasibility of the process often makes it difficult to manufacture large-scale kombucha-based pulp [ 7 ].…”

Advances in the Production of Biomaterials through Kombucha Using Food Waste: Concepts, Challenges, and Potential

et al. 2023

In recent years, several researchers have focused their studies on the development of sustainable biomaterials using renewable sources, including the incorporation of living biological systems. One of the best biomaterials is bacterial cellulose (BC). There are several ways to produce BC, from using a pure strain to producing the fermented drink kombucha, which has a symbiotic culture of bacteria and yeasts (SCOBY). Studies have shown that the use of agricultural waste can be a low-cost and sustainable way to create BC. This article conducts a literature review to analyze issues related to the creation of BC through kombucha production. The databases used were ScienceDirect, Scopus, Web of Science, and SpringerLink. A total of 42 articles, dated from 2018 to 2022, were referenced to write this review. The findings contributed to the discussion of three topics: (1) The production of BC through food waste (including patents in addition to the scientific literature); (2) Areas of research, sectors, and products that use BC (including research that did not use the kombucha drink, but used food waste as a source of carbon and nitrogen); and (3) Production, sustainability, and circular economy: perspectives, challenges, and trends in the use of BC (including some advantages and disadvantages of BC production through the kombucha drink).

Development of FexOy particle onto bacterial cellulose network by forced hydrolysis and its electrical conductivity

FexOy particle and bacterial cellulose composite sheet was successfully prepared by forced hydrolysis. The presence of Fe3+ ions in bacterial cellulose suspension significantly provided the positive charge due to electrostatic force as reported by Zeta potential. With the pH of 12 of bacterial cellulose suspension, particle was nucleated between bacterial cellulose networks. Fourier transform infrared exhibited Fe-O stretching. X-ray diffraction reported that the mixture of Fe2O3 and Fe3O4 was existed onto bacterial cellulose composite. Scanning electron microscope reported that FexOy particle was randomly distributed in bacterial cellulose network. Intensity of Fe was qualitatively observed by energy dispersive analysis. With the existence of FexOy particle, the composite illustrated the inferiority of thermal stability of 150℃. Furthermore, it was noted that the resistivity was reduced with respect to increment of FexOy particle, suggesting that electrical conductivity was then enhanced. It was remarkable to note that FexOy particle and bacterial cellulose composite sheet prepared from forced hydrolysis showed the excellent properties as a candidate for flexible electrode.
