Abstract :
Agarase can degradedagarto oligosaccharide and has a lot of benefits for food, cosmetics, and others. Many species of agar- degrader are marine-organism. Several agarases have been isolated from different genera of microorganisms found in seawater and marine sediments. Hypocreaceae sp. was isolated from sea water of Pari Islands, Seribu Islands, Jakarta, Indonesia. Based on the results of the 16S rDNA gene identification of 500 base pairs, A10 isolates had 99 % similarity toHypocreaceae sp. The extracellular agarase enzyme from Hypocreaceae sp. have optimum pH and temperature at 8 TrisHCl (0.148 μ.mL^-1) and 50 °C (0.182 μ.mL^-1), respectively. Agarase enzyme of Hypocreaceae sp. reach an optimum condition at the highest enzyme activity during incubation in 24 hours (0.323 μ.mL^-1). SDS Page revealed that there are two bands of protein produced by agarase of Hypocreaceae sp. which are at molecular weight of 39 kDa and 44 kDa and hydrolisis of Gelidium latifolium obtained 0,88% ethanol.
