Abstract

Because of its safety, biological activities, and unique properties, exopolysaccharide (EPS) from lactic acid bacteria (LAB) has been developed as a potential biopolymer. A few studies have investigated the EPS produced by marine LAB. This study reports the wound healing activity of an EPS produced by a marine isolate identified as EI6, in addition to assessing EI6's probiotic properties. EI6 demonstrated promising antimicrobial activity against different pathogenic bacteria, as well as the ability to withstand stomach pH 3, tolerate 0.3% bile salt concentration, and exhibit no signs of hemolysis. Furthermore, EI6 was able to produce 270 mg/L of EPS upon growth for 48 h at 37°C in an MRS medium enriched with 1.0% of sucrose. The chemical features of the novel EI6-EPS were investigated: the UV-vis estimated a high carbohydrate content of ~91.5%, and the FTIR emphasized its polysaccharide nature by the characteristic hydroxyl, amide I, II, & III, and glycosidic linkage regions. The GC-MS and NMR analyses revealed the existence of five monosaccharides, namely, rhamnose, galactose, mannose, glucose, and arabinose, existing mainly in the pyranose form and linked together by α- and β-glycosidic linkages. EI6-EPS was found to be safe (IC50 > 100 μg/ml) and induced human skin fibroblasts (HSF) proliferation and migration. These findings imply that EI6 can be used as a safe source of bioactive polymer in wound care.

摘要

由于其安全性、生物活性和独特性质,来自乳酸菌(LAB)的胞外多糖(EPS)已被开发为一种潜在的生物聚合物。一些研究已经对海洋乳酸菌产生的EPS进行了调查。本研究报告了一种被鉴定为EI6的海洋分离株产生的EPS的伤口愈合活性,此外还评估了EI6的益生菌特性。EI6对不同病原菌表现出有前景的抗菌活性,以及耐受胃pH 3、耐受0.3%胆盐浓度且无溶血迹象的能力。此外,EI6在含有1.0%蔗糖的MRS培养基中于37°C生长48小时后能够产生270 mg/L的EPS。对新型EI6-EPS的化学特征进行了研究:紫外可见光谱估计其碳水化合物含量高,约为91.5%,傅里叶变换红外光谱通过特征性的羟基、酰胺I、II和III以及糖苷键区域强调了其多糖性质。气相色谱-质谱联用和核磁共振分析揭示了五种单糖的存在,即鼠李糖、半乳糖、甘露糖、葡萄糖和阿拉伯糖,它们主要以吡喃糖形式存在,并通过α-和β-糖苷键连接在一起。发现EI6-EPS是安全的(IC50 > 100 μg/ml),并能诱导人皮肤成纤维细胞(HSF)增殖和迁移。这些发现意味着EI6可作为伤口护理中生物活性聚合物的安全来源。
