We studied the effect of an extracellular enzyme, E77 from a bacteria genus Streptomyces strain on jellyfish, Aurelia aurita. Aureria aurita dissolved completely within 1 hour at 50°C without stirring in presence of E77 containing solution. Without the enzyme, 83.5% of jellyfish remained in the fresh water and 75.3% in the seawater at 50°C even after 1 hour without stirring. Although the wastewater after E77 treatment revealed high value 1280mg/L of chemical oxygen demand (COD), by application of this new framed bioreactor packed with several microorganisms could reduce its value by 122mg/L.
