ABSTRACT / САЖЕТАК:
Long lasting use of plastic material leads to the accumulation of waste and environmental concerns. Therefore, it is necessary to find novel polymers which can be used as substitutes for non- degradable plastic. Levan is a fructose based polymer with great potential for use in different industries due to its convenient properties such as flexibility, biocompatibility, biodegradability and non-toxicity. In this study, six microorganisms were selected based on their degradation of bis(2- hydroxyethyl) terephtalate (BHET) and for the production of exopolysaccharide (EPS). The highest yield of EPS was obtained using two strains, namely Pseudomonas sp. 53 and Bacillus sp. 47 in media containing sucrose as carbon source. Strain Pseudomonas sp, 53 can also synthetize EPS in the presence of BHET. FTIR analysis showed that obtained EPS in high yield correspond to levan type of polysaccharide.
