Barley protein function as growth inhibitor in Saccharomyces cerevisiae

The extracted toxic barley protein showed different protein content depending on the barley strain and demonstrated an inhibitory effect on the growth of yeast and glucose consumption. Chinese barley Danpi-2 had the highest concentration of toxic protein of all the types barley tested. When the concentration of proteins was increased to 32 μg/ml, the inhibition ratio also went up by 50%. The SDS-PAGE electrophoresis pattern showed that the protein was stable and tolerant at the temperature of 100°C.
