Evaluation of dermal wound healing activity and in vitro antibacterial and antioxidant activities of a new exopolysaccharide produced by Lactobacillus sp.Ca6 (original) (raw)

International journal of biological macromolecules, 2017

Abstract

The present study aimed to evaluate the in vitro antibacterial and antioxidant activities and the in vivo wound healing performance of a noval exopolysaccharides (EPS-Ca6) produced by Lactobacillus sp.Ca6 strain. The results showed that EPS-Ca6 had a potential antioxidant activity determined through four different assays: DPPH scavenging activity, reducing power, β-carotene bleaching by linoleic acid assay, and Metal chelating activities. It also exhibited significant antibacterial activity against pathogenic bacteria Salmonella enterica and Micrococcus luteus. The wound healing activity of the EPS-Ca6, using excision wound model in rats, showed that this novel EPS accelerated significantly wound healing activity as compared to the control group, and a total closure was achieved after 14days of wound induction. Furthermore, histological examination of biopsies showed fully re-epithelialized wound with a complete epidermal regeneration. Overall the finding indicates that the EPS-Ca6 ...
