Bacterial cellulose (BC) is a flexible biopolymer having valuable properties like high purity (without hemicellulose and lignin), percentage of crystallinity, water retention, mechanical strength, biodegradability unique biocompatibility. Unlike plant cellulose, bacterial produced by many species. Recent advances in research have identified several producers BC but the key producer Komagataeiba...

In this work we developed electrospun lignin/cellulose acetate fiber-bead nanostructures and explored their potential as structuring agents for vegetable oils to be used eco-friendly lubricating oleogels. A variety of were obtained from solutions containing 20 or 30 wt. % eucalyptus Kraft lignin (EKL) cellulose (CA) in variable weight ratios 100:0 60:40 an N,N-dimethylformamide/acetone mixture....

Controlled release systems of agrochemicals have been developed in recent years. However, the design intelligent nanocarriers that can be manufactured with renewable and low-cost materials is still a challenge for agricultural applications. Lignocellulosic building blocks (cellulose, lignin, hemicellulose) are ideal candidates to manufacture ecofriendly given their low-cost, abundancy sustainab...

Two printing methods, extrusion and inkjet, are used to deposit tracks of PEDOT/PSS conducting polymer onto biopolymer films with a view to prepare implantable tissue mimics containing electronic devices. Extruded tracks offer lower printing resolution, but better electrical characteristics compared to inkjet printed tracks. The biopolymer–ink interaction results in narrower printed tracks comp...

Because of their lightweight structure, flexibility, and immunity to electromagnetic interference, polymer optical fibers (POFs) are used in numerous short-distance applications. Notably, the incorporation luminescent nanomaterials POFs offers amplification sensing for advanced nanophotonics. However, conventional suffer from nonsustainable components processes. Furthermore, traditionally under...

Biotechnology can be used to convert waste into valuable products. In this context, there is bacterial cellulose (BC), a natural biopolymer that transformed several useful materials, but its production limited due the high cost of culture media for industrialization. work, BC was produced from bacteria Komagataeibacter rhaeticus, using coffee grounds, sugarcane molasses and ethanol. The experim...

The hypolipidemic effect of an exo-biopolymer produced from a submerged mycelial culture of Hericium erinaceus was investigated in dietary-induced hyperlipidemic rats. Hypolipidemic effects were proportionally increased with the increasing concentration of the exo-biopolymer for oral administration. The exo-biopolymer, at the dose of 200 mg/kg body weight, substantially reduced the plasma total...

The purpose of this study was to develop the pathway of silk fibroin (SF) biopolymer surface induced cell membrane protein activation. Fibroblasts were used as an experimental model to evaluate the responses of cellular proteins induced by biopolymer material using a mass spectrometry-based profiling system. The surface was covered by multiwalled carbon nanotubes (CNTs) and SF to increase the s...

A reversible amine-carbamate approach has been developed to reduce the use of antisolvents such as water in coagulation biopolymers from ionic liquid (IL) solution and thus improve economy IL recycle. Cellulose chitin were recovered 1-ethyl-3-methylimidazolium acetate ([C 2 mim][OAc]) by introducing miscible amines triethanolamine (TEA), ethylenediamine (EDA), or butylamine (BA) bubbling CO at ...
