Abstract

본 발명은 포리아 코코스 곰팡이를 고체 또는 액체 진탕배양한 배양액에, 8N 질산 또는 30% 과산화수소수로 전처리한 석탄을 첨가하고, 25℃∼30℃에서 2∼10일간 배양함을 특징으로 하는 미생물 발효에 의한 갈탄의 방법을 제공한다. 갈탄의 침전을 방지하여 액화를 촉진하는 측면에서 볼 때 공기부양식 발효기를 이용한 배양이 바람직하다.The present invention adds coal pretreated with 8N nitric acid or 30% hydrogen peroxide to a culture medium in which the Poria cocos mold is shaken in solid or liquid, and incubated for 2 to 10 days at 25 ° C to 30 ° C. By means of lignite. In view of preventing lignite precipitation and promoting liquefaction, cultivation using an air-floating fermenter is preferred.
