Effects of medium components on Mycelial Growth and Polysaccharide production in Liquid Culcure of Coriolus versicolor

본 연구에서는 담자균류 중에 항암효과가 입증된 Coriolus versicolor의 균사체 생육과 다당체 생성에 유리한 배지를 선정하기 위하여 flask culture를 통하여 검토하였다. 임의의 배양조건 $27^{\circ}C$, 200rpm을 선택해 여러 탄소원과 질소원을 검토하여 각각 glucose와 yeast extract를 선택하였다.

This study was executed to investgate the effects of medium components on liquid culture in the flask culture of Coriolus versicolor. This work was focused on raising the mycelial growth and the polysaccharide production. In order to optimize the medium, different carbon and nitrogen sources were investgated. Glucose and yeast extract were chosen for the production of mycelia and polysaccharide as carbon and nitrogen sources, respectively, in the flask culture. For the mycelia growth and polysaccharide production, the medium contained glucose 20g/L, yeast extract 6g/L, $KH_2PO_4$ 0.46g/L, $MgSO_4.7H_2O$ 0.5g/L. The liquid culture conditions for the mycelial growth were $27^{\circ}C$, 200rpm and working volume 100mL using 250mL flask.
