Bacterial Cellulose Nanofibers [PDF]

, 2022
Cellulose is among the world’s wealthiest biopolymers and primarily has a wood, plant, and microbial source. To date, cellulose nanofibers (CNFs) are synthesized under controlled conditions (temperature, pH, and agitation). The bacterial synthesis of CNFs, so-called bacterial cellulose (BC), has become actively interested in recent times. These emerged

Effects of Anchovy, Mussel, and Shrimp Powders on the Flame Retardancy of Bacterial Cellulose

Journal of Natural Fibers
This study aims to fabricate bacterial cellulose with improved flame retardancy by applying anchovy, mussel, and shrimp powders. The elemental analysis confirmed that raw marine powders contained nitrogen and sulfur elements which could play important ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Rationally engineered polymeric interfaces for selective and dynamic recognition of vesicular agents

FEBS Open Bio, EarlyView.
This review explores how molecularly imprinted polymers can be engineered to recognize complex nanoscale vesicles, including extracellular vesicles and membrane‐enveloped viruses. By tailoring polymer cavities to vesicle surface chemistry and structure, these synthetic receptors support selective detection, separation, and integration with optical ...

Peculiarities of Bacterial Cellulose

Polymers
Cellulose is the most abundant renewable biopolymer, with bacterial cellulose (BC) emerging as a high-purity, sustainable alternative to plant-derived cellulose. While sharing the same chemical formula, BC possesses unique morphological characteristics, including a 3D nanofibrillar network, high crystallinity (>95%), and superior water-holding ...
