Abstract EN
Tow legume proteins (cowpea and common bean proteins) were isolated and esterified with methanol in the presence of hydrochloric acid for 10 h at 4°c to give esterification extent 82% and 79%; respectively.
esterification raised the pis (iso-electric points) of legume proteins from ph 4 for the native legume proteins, to ph 6 in the case of cowpea protein and ph 8 in the case of common bean.
applying methylated proteins at four different concentrations (0.5, 0.75,1 and 2 mg/ml) to petri dishes containing nutrient agar infected with two pathogenic gram- negative (enterobacter cloacae and serratia marcescens) and gram- positive bacteria (listeria monocytogenes) gave rise to concentrationdependent inhibition zones.
