초록

The optimum conditions of the production of exo-polymer by Ganoderma lucidum WK-003 and it's hepatoprotective effect was studied. Optimum conditions for the production of exo-polymer (3.18 g/$\ell$) by using shaken flask culture of G. lucidum WK-003 were pH 4.5, 30$^{\circ}C$, 120 rpm for 18 days cultivation. Also exo-polymer productio (7.15 g/$\ell$) was optimized by 5$\ell$ jar fermenter cultivation with condition of pH 4.5, 30$^{\circ}C$, 200 rpm, 1.0 vvm for 6 days cultivation. Glutamic pyruvic transaminase(GPT) activities in serum of intoxicated Sprague-Dawley rat were decreased from 704 IU/L to 330 IU/L by oral administration of the exo-polymer (20mg/kg$.$day)f or 4 consecutive days.
