Abstract
Bacterial cellulose (BC) is a multipurpose biopolymer with superior material properties, such as purity, high degree of porosity, relative high permeability to liquid and gases, high water-uptake capacity, tensile strength, and ultrafine network. This chapter explores the extraction and applications of BC from different sources. There are two main methods to produce BNC by bacterial strains. One is the static culture, which results in the accumulation of a gelatinous membrane of BNC is formed at the gas-liquid junction with the shape of the culture vessel. Applications of BC in immobilization of enzymes and cells, applications in cosmetics include facial mask, facial scrub, personal cleansing formulations, and contact lenses. BC for controlled drug delivery, transdermal drug delivery, dental drug delivery, protein delivery, tissue engineering drug delivery, macromolecular prodrug delivery, and molecularly imprinted polymer-based enantioselective drug delivery are also discussed in this chapter.
