Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Bacterial cellulose is recognized as a multifaceted, versatile biomaterial with abundant applications. It is a completely biodegradable, ecological, non-toxic, chemically stable, and biocompatible material. Unlike plant cellulose, it is characterized by high crystallinity, a higher degree of polymerization, and higher tensile strength and Young’s modulus. In addition, bacterial cellulose, unlike vegetable cellulose, has a smaller diameter of fibres and hence possesses higher hydrophilicity. The properties of bacterial cellulose depend on multiple factors, such as culture conditions, the type of microorganisms, and nutrients present in the growth medium. These factors have a huge impact on the properties of the polymer, such as strength, crystallinity, degree of polymerization, or hygroscopicity.
