“…Cellulose was developed through Komagataeibacte (genre) bacteria, which digests the kombucha tea and produces cellulose film [49]. When this material is dried, it resembles soft bovine leather, and it could be used in diabetic orthopedic footwear, since they have sensitivity in their feet and this material provides the shoe with a soft surface [49].…”

Footwear material is of great importance mainly considering the user's health. There are many components in contact with upper and mainly lower part of foot, being the sole essential part to weight distribution, muscle activity and vertebral column. This study aimed to verify how the natural fibers are applied at Brazilian market footwear, demonstrating the types of raw materials utilized, textile constructions and other variables. As well as comparing the information at natural fibers applications data from economics sources and material employment at the footwear international market. The methodology was based in literature research and interviews with Brazilian companies. The employment of natural fibers in footwear corresponds to a small part in comparison of synthetic fibers. Cellulosic fibers have been researched to reinforce rubbers and they are applied to sole as snow footwear. In addition, these fibers are being researched as biodegradable materials, showing innovations for instance, the use of leather waste, coconut fiber and latex, multilayers fabrics and finishing process adding bactericide properties to cotton. Brazilian footwear industry is finding solutions to reduce production costs in order to compete in the international market. One of the strategies is the gradual replacement of leather by fabrics, synthetic polymers and rubbers. The interviews identified the employment of cotton, raffia and jute fabrics especially in footwear summer collections. Thus, the increasing of researches about recycling footwear components and the development of biodegradable materials points a sustainability trend in this sector.

“…Garcia and Prieto proposed bacterial cellulose (BC) leather as an alternative to conventional leather. With potential to become industrial scale and produce a product similar to finished leather, this alternative could be used in automotive industries while reducing waste and improving quality (Garcia & Prieto, 2018); however, currently, BC is highly expensive and difficult to develop and maintain.…”

“…Dimensions of BNC fibres give this polymer properties of a nanomaterial. Due to its unique features, BNC has found applications in various areas of biotechnology, medicine and industry (reviewed in Jang et al 2017 ; García and Prieto 2019 ; Gorgieva and Trček 2019 ; Wang et al 2019 ). It also constitutes a promising material in food applications, e.g.…”

The strains of the Komagataeibacter genus have been shown to be the most efficient bacterial nanocellulose producers. Although exploited for many decades, the studies of these species focused mainly on the optimisation of cellulose synthesis process through modification of culturing conditions in the industrially relevant settings. Molecular physiology of Komagataeibacter was poorly understood and only a few studies explored genetic engineering as a strategy for strain improvement. Only since recently the systemic information of the Komagataeibacter species has been accumulating in the form of omics datasets representing sequenced genomes, transcriptomes, proteomes and metabolomes. Genetic analyses of the mutants generated in the untargeted strain modification studies have drawn attention to other important proteins, beyond those of the core catalytic machinery of the cellulose synthase complex. Recently, modern molecular and synthetic biology tools have been developed which showed the potential for improving targeted strain engineering. Taking the advantage of the gathered knowledge should allow for better understanding of the genotype-phenotype relationship which is necessary for robust modelling of metabolism as well as selection and testing of new molecular engineering targets. In this review, we discuss the current progress in the area of Komagataeibacter systems biology and its impact on the research aimed at scaled-up cellulose synthesis as well as BNC functionalisation. Key points • The accumulated omics datasets advanced the systemic understanding of Komagataeibacter physiology at the molecular level. • Untargeted and targeted strain modification approaches have been applied to improve nanocellulose yield and properties. • The development of modern molecular and synthetic biology tools presents a potential for enhancing targeted strain engineering. • The accumulating omic information should improve modelling of Komagataeibacter's metabolism as well as selection and testing of new molecular engineering targets.
