“…. 101), ( 040), ( 002) planes, can be attributed to the crystalline cellulose hydrolysis with acids that might remove the amorphous portion of cellulose [28]. Subsequently, the appearance of MIL-101(Fe) characteristic peaks demonstrated that the decoration of MIL-101(Fe) on NC did not change the natural characteristics of both materials.…”

In this research, the combination of the photocatalytic activity of the semiconductor Ag3PO4 and the as-synthesized MIL-101(Fe)@nanocellulose (NC) from agricultural and bottle waste sources exhibited great photocatalytic efficiency. The Ag3PO4@MIL-101(Fe)@nanocelllulose (NC) composite has overcome the disadvantages of pure Ag3PO4 and significantly improved the photocatalytic activity. Structural characteristics, morphology of the materials were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscope (EDX), and UV–vis diffuse reflectance spectroscopy (UV-vis DRS) methods. From the obtained results, composite has a narrow bandgap energy (2.45 eV) and excellent catalytic performance in the photodegradation of Tetracycline pollutants (99.7 % after 120 min). It demonstrates the development of new catalysts made from agricultural waste sources that show high stability, ease of fabrication and can operate in natural light for environmental remediation.

Bacterial cellulose (BC) was synthesized using Gluconacetobacter xylinus (BCRC 14182). Synthesized BC was powdered and dissolved in Bis(ethylenediamine) copper (II) hydroxide (Cuen) solution to introduce the amine (NH2) group onto the BC network to yield modified BC (mBC) which was then blended with poly (vinyl alcohol) (PVA) and subsequently crosslinked with genipin (Gp). Pristine, modified and crosslinked hydrogels were studied using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and swelling behavior in water. FTIR revealed a distortion on the BC network chain via a reduction in the absorption of OH peak of mBC and the emergence of peaks at 1587 and 1560 cm-1 attributed to N-H stretching of the induced NH2 group. SEM confirmed the 3-D fibril and porous structure of BC which became distorted after modification and crosslinking. The hydrogels showed equilibrium water content of 86.5%, 67.5%, 66.7% and 33.0 % for BC, PVA, mBC-PVA and mBC-PVA-Gp, respectively. The decreased swelling in mBC-PVA-Gp indicated that genipin was able to crosslink the modified BC.

“…There are different fermentation methods for growing bacterial cellulose such as static and shaken fermentations. For static fermentation, the liquid media is incubated in shallow trays, and the cellulose grows as an intertwined mat of cellulose microfibres at the surface [29]. Shaken fermentations are carried out in conical flasks incubated in a shaking incubator and produce spherical beads of various sizes depending on the conditions [27,29].…”

The need for circular textiles has led to an interest in the production of biologically derived materials, generating new research into the bioproduction of textiles through design and interdisciplinary approaches. Bacterial cellulose has been produced directly from fermentation into sheets but not yet investigated in terms of producing filaments directly from fermentation. This leaves a wealth of material qualities unexplored. Further, by growing the material directly into filaments, production such as wet spinning are made redundant, thus reducing textile manufacturing steps. The aim of this study was to grow the bio-material, namely bacterial cellulose directly into a filament. This was achieved using a method of co-designing with the characteristics of biological materials. The method combines approaches of material-driven textile design and human-centred co-design to investigate co-designing with the characteristics of living materials for biological material production. The project is part of a wider exploration of bio-manufacturing textiles from waste. The practice-based approach brought together biological sciences and material design through a series of iterative experiments. This, in turn, resulted in designing with the inherent characteristics of bacterial cellulose, and by doing so filaments were designed to be fabricated directly from fermentation. In this investigation, creative exploration was encouraged within a biological laboratory space, showing how interdisciplinary collaboration can offer innovative alternative bioproduction routes for textile filament production.
