Process for preparing biomaterial with cartilage properties, intended for implants for reconstructive surgery

摘要

A method of production of a cartilage-like biomaterial designed for implants for reconstructive surgery by using microbial cellulose produced in a stationary culture of bacterium Gluconacetobacter xylinus consists in cultivation of the bacterium in a flat bioreactor or polyethylene tubes, modeling of produced and purified cellulose into spatial construction with desired shape and modification of the latter by treatment with 30% aqueous solution of sodium hydroxide, rinsing with distilled water, treatment with 10% aqueous solution of acetic acid and repeated rinsing with distilled water until pH of cellulose material reaches 5.6-6.8.
