The area of its applications has rapidly expanded in the pharmaceutical and cosmetic fields, food, medicine, tissue engineering and biotechnology. This paper aims to expand the previous review that presents the use of gellan in the food industry and make an overview of other polysaccharide bioapplications. Considering the interest it has attracted in recent years, the paper details the use of gellan in pharmacy, medicine and tissue engineering. Also, other gellan bioapplications in cosmetics, biotechnology, microbiology are concisely presented. 收起
