NOVEL ALGINASE AND A DECOMPOSITION METHOD THEREOF

摘要

PURPOSE: A novel alginase and a decomposition method thereof are provided to enhance decomposition activity of alginic acid and to produce more polymerized alginic acid products.;CONSTITUTION: A novel alginase has an amino acid sequence described in the sequence number 1(SEQ ID NO:1). The enzyme is originated from Saccharophagus degradans. The gene coding the alginase has the base sequence described in the sequence number 2. The composition for the alginic acid decomposition includes alginase or a gene coding the same. The alginic acid is oligo alginic acid. The alginase produces oligo alginic acid products by processing the alginase to the alginic acid or oligo alginic acid. The polymerization degree of the oligo alginic acid product is 2-5. The reaction is operated in the pH of 6-10, at 30-60 deg. Celsius or under the existence of Na+ cation presence.;COPYRIGHT KIPO 2013
