Optimization and characterization of Alginic acid synthesized from a novel strain of Pseudomonas stutzeri

Abstract

Alginate is a group of water-soluble linear polysaccharides comprising of variable units of α-l-guluronic and β-d-mannuronic acid. The alginates are in high demand in biomedical, pharmaceutical and bioengineering applications. In the present study, we have isolated a strain of Pseudomonas stutzeri that has potential alginate synthesis. The biochemical and physiochemical characteristic including Carbazole assay, DSC, FTIR and H NMR were confirmed the alginate synthesis efficacy by P. stutzeri. Evaluation of P. stutzeri alginate for the removal of heavy metals such as Chromium, Cobalt and Lead showed that it effectively adsorbs heavy metals. Further analysis of gelling ability and cytotoxicity evaluation revealed that the alginate can be reconstituted as hydrogel and scaffold. Overall, our findings suggest that the strain P. stutzeri TN_Alg Syn may be used to produce alginate at commercial level that has the potential bioremediation and biomedical applications.
