Celulose bacteriana produzida a partir de coprodutos da agroindustria para remoção de corantes de resíduos de laboratório

Abstract

Cellulose is a natural polymer synthesized by plants and some species of acetic acid bacteria (AAB). Bacterial cellulose (BC) is a natural polymer that can be used by the pharmaceutical and food industries and in the recovery of environments contaminated with metals. In order for companies to increasingly use this biomaterial, it is important to seek new sources of carbon at more attractive costs. The BC has advantageous physicochemical characteristics such as high purity, high crystallinity, high tensile strength and high porosity. An economic and environmental alternative is to use nutrients from alternative sources such as agro-industrial residues. This theoretical reference discusses possible alternative substrates for BC production, the ideal conditions for producing this biopolymer, its molecular structure and the cost of production by conventional and alternative means.
