Abstract
Objective: The production of new natural pharmaceutical agents that increase the efficiency of chemotherapy
without affecting the normal cells is the goal of all researchers. Therefore, the present study expects to evaluate
the antioxidant and anticancer studies against MCF-7 cell lines of EPS produced by novel Egyptian marine bacterial
strain. Methods: Marine bacterium was isolated, purified and identified by 16S rRNA gene amplification and sequence
analyses. MHMEPS (the produced EPS) was analyzed by Fourier Transform Infra-red (FTIR), monosugars identification
by HPLC, molecular weight estimation and sulfur content were determined. While, in-vitro antioxidants characters
was determined using various methods and anticancer studies against MCF-7 cell lines. Results: Bacillus velezensis
MHM3 produced 5.8 g/L of MHMEPS. The chemical analysis of MHMEPS showed 24% uronic acid and 18.19%
sulfate and monosugars glucuronic acid, glucose, fructose and rhamnose with molar ratio of 4.00: 2.00: 1.00: 0.13,
correspondingly, with an overall weight average molecular weight Mw of 1.145×104 g/mol and the number average of
molecular weights Mn of 5.155 ×103 g/mol. The FTIR analysis and periodate ...
