Abstract

To investigate optimal conditions for the protoplast formation and regeneration of Phanerochaete chrysosporium, preparations of three enzymes were used to liberate protoplasts from its 20 hrs-old mycelium on cellophan membrane covered agar media. Novozym 234 alone with 0.6M sucrose was the most effective for isolation of protoplasts from the mycelium with 3hrs incubation time at $39^{\circ}C$ in shaking condition of 120 rpm. The poly-R medium stabilized with 0.6M mannitol was the best for regeneration of the protoplasts.

Phanerochaete chrysosporium ME446의 원형질체 생성 및 재생을 위한 원형질체 분리에 알맞은 세포벽 분해효소로는 Novozym 234이였으며 삼투압 조절제로서는 0.6M sucrose, 처리시간은 $2.5{\sim}3$시간이었다. 균사체 배양일수는 대수기에 해당하는 42시간이었으며 원형질체 재생에 알맞은 배지로는 0.6M mannitol을 첨가한 poly-R 배지였다.
