Bacterial cellulose – applications

Dominika Bednarczyk, Izabela Betlej, Piotr Boruszewski

Abstract


The paper presents the possibilities of using bacterial cellulose in numerous branches of industry. Literature data indicate very good mechanical and physical strength parameters of the bacterial biopolymer, such as high tensile strength, flexibility, absorbency, and a much higher degree of polymerization and crystallinity compared to plant-derived cellulose. The conducted query confirms that bacterial cellulose, as a polymer devoid of lignin and hemicelluloses, can be much easier processed and used for various applications in various industries and sectors of the economy, from medicine to the paper and electronic industry.

Bacterial cellulose - factors determining the efficiency of synthesis

Dominika Bednarczyk, Izbela Betlej, Piotr Boruszewski,

Abstract


The efficiency of bacterial cellulose synthesis, with the exception of the type of bacteria that produce it, is determined by many other factors, such as the type of culture medium, sugar content and nitrogen source in the medium, temperature and amount of oxygen, pH of the medium, surface area on which it can form a membrane made of synthesized cellulose, or the presence of other microorganisms. Optimally selected medium composition and cultivation conditions are important for the proper growth of bacteria, which stimulates the formation of microbial cellulose. In this paper, on the basis of a literature review, information on the influence of selected factors influencing the course and efficiency of bacterial cellulose synthesis is presented.
