Self-Grown Bacterial Cellulose Capsules Made through Emulsion Templating

Microcapsules made of synthetic polymers are used for the release cargo in agriculture, food, and cosmetics but often difficult to be degraded environment. To diminish environmental impact microcapsules, we use biofilm-forming ability bacteria grow cellulose-based biodegradable microcapsules. The present work focuses on design optimization self-grown bacterial cellulose capsules. In contrast their conventionally attributed pathogenic role, self-secreted biofilms represent a multifunctional class biomaterials. strain this work, Gluconacetobacter xylinus, is able survive proliferate various conditions by forming as part its lifecycle. Cellulose one main components these protective layers known outstanding mechanical properties. Provided enough nutrients oxygen, produced self-assemble at interface any given three-dimensional template could novel stabilization concept water-in-oil emulsions. Using microfluidic setup controlled emulsification, demonstrate that capsules can with tunable size monodispersity. Furthermore, show successful droplet formation functions concentration, size, surfactant type. obtained results first milestone production self-assembled vast range applications such flavor, fragrance, agrochemicals, nutrients, drug encapsulation.
