Description/Abstract | Production of alpha-amylase (alpha-4, glucan 4-glucanohydrolase, EC 3.2.1.1) by microorganisms has been practiced for many years in small and large scale operations and the literature on this enzyme is voluminous.^Aspergillus niger and Aspergillus oryzae have been reported as the main fungal species used for commercial production of the enzyme.^On the other hand, large volumes of low-cost agricultural products such as acorn (the perisperm-free dry seed contains approximately 60% starch) are wasted in many countries and provide a challenge to biotechnology to efficiently utilize these rich sources of starch for the production of high added value products like enzymes.^C. gigantea is an edible puffball excreting high levels of alpha-amylase when cultivated on different sources of starch containing elevated quantities of toxic tannic compounds.^This fungus has been employed for the production of microbial protein from wastes and acorns containing high levels of toxic tannic compounds.^The same fungus was also reported to grow on both hydrolyzable and condensed tannins as sole carbon sources.^The present work was undertaken to investigate certain kinetic characteristics of alpha-amylase and biomass production by C. gigantea grown on soluble and acorn starch in a lab fermenter.^(Refs.^18). |
