“…In the bending mode, the BC films showed higher piezoelectric responses with values ranging from 55-158 pC/N and 40-71 pC/N for BC-glucose and BC-crude glycerol films, respectively. The bending mode piezoelectric sensitivities from BC-glucose is higher to that observed in our previous study using BC-glucose films synthesized by K. xylinus DSM 2325 (Sriplai et al 2020). This implies the application potential of K. rhaeticus ENS9a BC films in sensing applications, for instance in energy harvesting applications where bending mode sensitivities are critical.…”

“…Oven-dried BC films prepared from MA/9 medium containing 2% glucose and crude glycerol were used in this study (see section BC film preparation and dry weight measurements). Sensor construction, piezoelectric sensitivity measurement setup and sensitivity calculations were conducted as described previously (Mangayil et al 2017;Sriplai et al 2020) with slight variations. The hydrated BC film was sandwiched between two silver electrodes (100 nm) vacuum evaporated on poly(ethylene-terephthalate) (PET) film and left to dry O/N at 45°C resulting in a self-adhered construct.…”

Bacterial cellulose (BC) is a biodegradable polymer that benefits in purity, crystallinity and superior optical, structural and mechanical properties. Such properties facilitate BC to replace the conventional non-biodegradable materials used, for instance, in sensing applications. However, BC production is largely conducted in conventional medium containing model substrates and complex carbon-containing compounds. Aiming towards the production of eco-friendly piezoelectric-responsive BC films, we isolated and characterized a novel bacterial strain affiliated to Komagataeibacter rhaeticus. The K. rhaeticus ENS9a strain synthesized BC in minimal medium containing crude glycerol, generating a titer of 2.9 ± 0.3 g/L BC. This is, to the best of our knowledge, the highest BC titer reported from an unoptimized minimal medium containing crude glycerol. Interestingly, the films prepared from crude glycerol showed normal force and bending mode sensitivities of 6–11 pC/N and 40–71 pC/N, respectively, demonstrating a green platform to address both bioprocess waste valorization and implementation of cellulose-based alternatives for the non-sustainable and non-biodegradable materials, such as fluoropolymers or lead containing piezoceramics, used in sensing applications. In silico genome analysis predicted genes partaking in carbohydrate metabolism, BC biogenesis, and nitrogen fixation/regulation. Graphic abstract

Bacterial nanocellulose (Bnc) has been drawing enormous attention because of its versatile properties. Herein, we shed light on the BNC production by a novel bacterial isolate (MD1) utilizing various agroindustrial wastes. Using 16S rRNA nucleotide sequences, the isolate was identified as Komagataeibacter saccharivorans MD1. For the first time, BNC synthesis by K. saccharivorans MD1 was investigated utilizing wastes of palm date, fig, and sugarcane molasses along with glucose on the Hestrin-Schramm (HS) medium as a control. After incubation for 168 h, the highest BNC yield was perceived on the molasses medium recording 3.9 g/L with an initial concentration of (v/v) 10%. The physicochemical characteristics of the BNC sheets were inspected adopting field-emission scanning electron microscope (FESEM), atomic force microscopy (AFM), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) analysis. The FESEM characterization revealed no impact of the wastes on either fiber diameter or the branching scheme, whereas the AFM depicted a BNC film with minimal roughness was generated using date wastes. Furthermore, a high crystallinity index was estimated by XRD up to 94% for the date wastes-derived BNC, while the FTIR analyses exhibited very similar profiles for all BNC films. Additionally, mechanical characteristics and water holding capacity of the produced Bncs were studied. Our findings substantiated that expensive substrates could be exchanged by agro-industrial wastes for Bnc production conserving its remarkable physical and microstructural properties. In the last decades, bacterial nanocellulose (BNC) has earned increasing global interest because of its remarkable physical and chemical properties, including green processing, low production costs, elevated mechanical properties, hydrophilicity, excellent biocompatibility, and biodegradability 1,2. Certain gram-negative non-pathogenic bacterial genera like Rhizobium, Xanthococcus, Pseudomonas, Azotobacter, Aerobacter, and Alcaligenes were reported to produce nanocellulose extracellularly, but the most common BNC-producing strains belong to the genus Komagataeibacter (formerly Acetobacter or commonly acetic acid bacteria) 1. Bacteria produce the BNC through a process of dual coupled steps: polymerization and crystallization. In the bacterial cytoplasm, glucose residues polymerize to β-1,4 glucan linear chains where they are extracellularly secreted. The developed chains are crystallized to microfibrils, then certain numbers of microfibrils consolidate to materialize highly pure 3D porous network of entangled nanoribbons of 20-60 nm in width 3 .

“…In order to overcome such limitations, synthetic and biodegradable polymers, as well as polymeric composites have been used to develop PENGs (Sun, Zeng, & Li, 2020). For instance, polysaccharides, such as chitosan (Hänninen, Rajala, Salpavaara, Kellomäki, & Tuukkanen, 2016, cellulose (Rajala et al, 2016;Sriplai et al, 2020;Tuukkanen & Rajala, 2018) and bacterial cellulose (Mangayil et al, 2017) have been reported to be used as lightweight and flexible piezoelectric materials. However, PENGs are known to be efficient when the frequency of the mechanical excitation ranges 60−100 Hz (Han et al, 2013;Liu, Zhong, Lee, Lee, & Lin, 2018).…”

Triboelectric nanogenerators (TENGs) are versatile electronic devices used for environmental energy harvesting and self-powered electronics with a wide range of potential applications. The rapid development of TENGs has caused great concern regarding the environmental impacts of conventional electronic devices. Under this context, researching alternatives to synthetic and toxic materials in electronics are of major significance. In this review, we focused on TENGs based on natural polysaccharide materials. Firstly, a general overview of the working mechanisms and materials for high-performance TENGs were summarized and discussed. Then, the recent progress of polysaccharide-based TENGs along with their potential applications reported in the literature from 2015 to 2020 was reviewed. Here, we aimed to present polysaccharide polymers as a promising and viable alternative to the development of green TENGs and tackle the challenges of recycling e-wastes.
