The kinetics of growth and α-amylase production of a novel Candida wangnamkhiaoensis yeast strain were studied in single-stage steady-state continuous cultures. This was performed in a split-cylinder internal-loop airlift bioreactor, using a variety of carbon sources as fermentation substrates. Results

Despite being widely used, there is no standard protocol for α-amylase activity measurement with starch azure substrate. Boiling pre-treatment of starch azure suspension increased the reaction rate of hydrolysis catalysed by human salivary α-amylase (HSA) or porcine pancreatic α-amylase (PPA)
