PROJECT BACKGROUND
BACTERIAL CELLULOSE
Cellulose was the most common biopolymer in the world. The primary form in which the material is found is lignocellulotic in trees, however there are other sources such as bacterial cellulose [1].This was first described by Luis Pasteur in the previous century and reported for the first time its use in a Philippine dessert called coconut cream, however, it was not until 1886 when it was reported as a type of cellulose in an acetic fermentation, after being observed as a floating film in a culture medium[2]. In recent years, several studies have been carried out on the usefulness of bacterial cellulose due to its high degree of purity and its simpler structure than that obtained from plants, in addition to the speed of polymer formation, reducing costs and environmental impact in the purification process to eliminate the lignin and other impurities of the material to be applied in the industries[3]. . Bacterial cellulose has been used mainly in the paper industry, in the food for the realization of various desserts and strong dishes and as a material for garment development, due to its great flexibility, it is also impregnated with several nanoparticles to give antimicrobial, antifungal capacities[4]. Its ability to be combined with other proteins gives it the advantage to create new polymers with other desired properties such as bioplastics and drug administrators when combined with therapeutic proteins[5]. The existing biocompatibility between bacterial cellulose and human cells has led to the use of the polymer as a matrix for the regeneration of organs and tissues such as cartilage and skin[6].
