Effect of Glycolipoprotein Biosurfactant from Enterococcus faecium on the viability of Breast cancer cell lines.

Abstract

Objective : This study , was research for cytotoxicity of bio-surfactant created by Enterococcus faecium isolated from feces of Iraqi healthy breast-fed infants with  age < 6 months. Methods :  Cold acetone precipitation was used to the extraction of extracellular Glycolipoprotein biosurfactant and partially purify it. Biosurfactant was then evaluated against two the cell lines, a Breast cancer MCF-7 cell line and a human normal fibroblast cell line NHF), specifically for cell survival and proliferation.   Results :  At all concentrations  with varying percentage, The viability of the MCF-7 cancer cell line was shown to be reduced with the addition of biosurfactant.; maximum inhibition percentage was 74.2% at a 100 µg/ml concentration, which is lesser than 45.5% cytotoxicity Of NHF healthy fibroblasts cell line. Conclusions : The findings of this study are highly encouraging in terms of the potential of Glycolipoprotein biosurfactants to treat cancer and encourage additional research with different cell lines.
