The effect of physical factors on the production of α-Amylase from isolate 1B using response surface methodology
Study of α-amylase is still ongoing because of its role in industry. Therefore, an enhancement should be done in α-amylase production along with the current technology. The main objective of this study is the optimization of culture conditions or physical factors to enhance α-amylase production. A-a...
