Marine-Derived Fungi as a Valuable Resource for Amylases Activity Screening

Marine microbial enzymes including amylases are important in different industrial production due to their properties and applications. This study was focused on the screening of marine-derived fungi for amylase activities. First, we isolated a number from sediments South China Sea. By method dish (in vitro), subsequently obtained series amylase-producing fungal strains. The cell-lysate activities produced by marine toward starch hydrolysis were achieved with dinitrosalyicylic acid (DNS) method. In addition, effect pH temperature activities, thermal stability discussed. Results showed that out 57 isolates Aspergillus flavus 9261 found produce best activity 10.7482 U/mg (wet mycelia). exhibited remarkable thermostability no loss after incubation at 50 °C 5.0 1 h, respectively. results provide advances discovering biotechnology relevance.
