Evaluation of dermal wound healing activity and in vitro antibacterial and antioxidant activities of a new exopolysaccharide produced by Lactobacillus sp.Ca6
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-Ca 6 ) produced by Lactobacillus sp.Ca 6 strain. The results showed that EPS-Ca 6 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-Ca 6 , 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 14 days 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-Ca 6 might be useful as a wound healing agent in modern medicine.
