COMPARATIVE ANALYSIS OF VARIOUS EXTRACTION METHODS UPON THE YIELD AND CHEMICAL COMPOSITION OF BACTERIAL CELLULOSE PRODUCED BY NOVACETIMONAS HANSENII (OR418572)

Abstract
Abstract - Bacterial cellulose (BC) is a promising biopolymer produced by aerobic bacteria. Compared with plants, BC has many superior qualities, like high water-holding capacity, biocompatibility, high purity, crystallinity, and biodegradability. Its unique physio-chemical and morphological features are helpful in various industries like paper making, food packaging, and pharmaceutical. The purification process plays a significant role in determining the quality of BC. BC produced in the air-liquid interface of the fermentation medium is subjected to alkali treatment for purification. The proper setup and subsequent characterization are essential for experiments on biomaterials. BC is used for various medical applications, including medicine. This study aims to determine the influence of various purification processes on BC and introduce the best purification method. Method of purification is not affecting the weight of BC. Chemical changes are reflected in FTIR studies, and the morphological changes are visible on SEM images. Even though there are not significant chemical changes morphological changes are observed. The proposed method is comparatively easier and provide good quality cellulose. Keywords -BC, FTIR, SEM, Purification
