of the extracted fractions and their hydrolysates were determined.
Viscozyme hydrolysate exhibited the highest phenolic content and a DPPH scavenging activity of about 92% with more than 50% increase over its mother fraction. It also showed a high antibacterial activity relative to commercial antibiotics. Phenolic content determination and HPLC analysis suggested that the high antioxidant activity of viscozyme hydrolysate could be owed to its short-length chain and its high content of phenolic compounds as well as the predominance of mannose and galactose sugars in the polysaccharide chain
