Abstract

The effect of amino acids (glutamic, aspartic, beta-alanine, phenylalanine, methionine) on the glucoamylase biosynthesis by Endomycopsis species 20-9 was studied. Monoaminodicarboxylic acids produced a stimulating effect on the glucoamylase synthesis. Their addition at optimal concentrations of 0.2 to 0.4% increased by 54--69% glucoamylase activity of Endomycopsis sp. 20-9 upon submerged cultivation on the medium containing 3% maize extract and 1% starch. An application of this amino acid nutrition during cultivation did not produce a significant effect on the microbial glucoamylase activity.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
