ABSTRACT
In this study, the chemical structure and bioactive properties of the EPS of Pediococcus acidilactici MT41-11 isolated from camel milk were investigated. Two polysaccharide fractions (EPS-1, EPS-2) with molecular weights about 69.0 kDa were obtained, which were purified using DEAE-Sepharose and Sephadex G-100 chromatography. Based on monosaccharide composition, FT-IR, and 1D, 2D NMR spectra, concluded that EPS-1 had a backbone composed of â2)-α-d-Manp-(1â, â3)-α-d-Manp-(1â and with branches containing α-d-Manp-(1â, EPS-2 had a backbone composed of â6)-ß-d-Glcp-(1â, and with branches containing â2)-α-l-Fucp-(1â, â3)-α-d-Glcp-(1â, â2)-α-d-Glcp-(1â, ß-d-Glcp-(1â, and α-d-Glcp-(1â. Remarkably, in vitro assays showed that EPS possessed multiple bioactive properties, including stimulating Lactobacillus growth and a high DPPH free radical scavenging activity. Also, it has a good ability to anti-biofilms. Overall, the analysis of all data showed EPS from P. acidilactici MT41-11 can be used as anti-oxidant, anti-biofilm agent, and also as a potential candidate prebiotic for health food or medicine industry.
