“…Functionalization or modification of bacterial cellulose has mainly been achieved by chemical or mechanical modifications of the cellulose matrix or via changing culturing conditions (7,22), whereas only a few attempts at genetic engineering have been made (13,23). However, genetic engineering may allow a greater range of materials to be produced, by enabling fine control over cellulose synthesis genes and production of proteincellulose composite biomaterials.…”

Bacterial cellulose is a strong and ultrapure form of cellulose produced naturally by several species of the Acetobacteraceae. Its high strength, purity, and biocompatibility make it of great interest to materials science; however, precise control of its biosynthesis has remained a challenge for biotechnology. Here we isolate a strain of Komagataeibacter rhaeticus (K. rhaeticus iGEM) that can produce cellulose at high yields, grow in low-nitrogen conditions, and is highly resistant to toxic chemicals. We achieved external control over its bacterial cellulose production through development of a modular genetic toolkit that enables rational reprogramming of the cell. To further its use as an organism for biotechnology, we sequenced its genome and demonstrate genetic circuits that enable functionalization and patterning of heterologous gene expression within the cellulose matrix. This work lays the foundations for using genetic engineering to produce cellulose-based materials, with numerous applications in basic science, materials engineering, and biotechnology.

“…BC is already used commercially in high-end acoustic products, in medical wound dressings, and to make many other goods (Lee et al, 2014). At the laboratory scale, it has even been used to create artificial blood vessels and biodegradable tissue scaffolds, and has shown promise in organic light-emitting diode displays, flexible electrodes, sensors and other devices (Hu et al, 2014). Goodyear Tire, Kimberly-Clark Corp. and Sony Corp., among others, have all filed patents involving the use of BC in some way.…”

“…Bacterial cellulose (BC) is one such material that has drawn attention in recent years. BC is extracellular cellulose synthesized by a class of acetic acid producing bacteria from monosaccharides, disaccharides, and alcohols in aqueous media (Hu et al, 2014;Shah et al, 2013). Glucose chains are produced inside the bacterial body during fermentation processes and then being extruded out of the body.…”

IntroductionPlant cellulose (such as cotton, flax, and wood pulp) has long been utilized to produce textile materials. The hydrophilicity, soft hand, medium to high strength and durability, biodegradability, and easy coloration make these cellulosic materials good choices for consumer textile products. With the increasing consumption of textiles due to population growth and living standard improvement, the burden on growing these cellulose containing plants on diminishing lands has been escalating, which resulted in higher material price. The environmental impacts of growing the plants (e.g., fertilizer and pesticides, soil erosion and desertification, and water use in irrigation) and from manufacturing the cellulose into textiles (e.g., chemicals used to remove lignin and hemicellulose, water and energy use) are receiving more concerns. Therefore, people are looking for alternative materials. Bacterial cellulose (BC) is one such material that has drawn attention in recent years. BC is extracellular cellulose synthesized by a class of acetic acid producing bacteria from monosaccharides, disaccharides, and alcohols in aqueous media (Hu et al., 2014;Shah et al., 2013). Glucose chains are produced inside the bacterial body during fermentation processes and then being extruded out of the body. The chains combine and form cellulosic nanofibers. A nanofiber nonwoven web is then generated from these nanofibers on the surface of the media. BC fibers have high purity, high crystallinity, and high degree of polymerization which impart BC high tensile strength (especially wet tensile strength), high water holding capacity, and slow water evaporation rate. The porous nonwoven web structure provides the material large surface area which increases the ability of chemical modifications. Furthermore, the material is biodegradable, biocompatible, fast to produce, and threedimensionally moldable. BC has been researched for possible applications for food, biomedical, and biotechnology. Although textiles are mentioned as potential applications of BC (Çakar et al., 2014), the authors have not seen any published research studying the various properties that are critical to textile products such as apparel and footwear. The purpose of this study was to investigate the possibility of using BC nonwoven as textile fabrics to make consumer products. The objectives were: 1) to study the influences of fermentation conditions on the production of BC fabric; 2) to investigate the physical and mechanical properties of BC nonwovens (thickness, weight, tensile strength, tearing strength, and stiffness); and 3) to study the possibility of producing inherently colored BC nonwovens. Materials and Testing BC Fabric Production: Symbiotic culture of bacteria and yeast (SCOBY) containing Acetobacter, vinegar, cane sugar, and tea were used to prepare the aqueous bath. The fermentation was taken place in an oven at 23°C. For objective 1, parameters studied included sugar concentration in the bath (10% and 20% by weight), tea type (black, green, and red)...
