Abstract
In order to minimize the mycelial pellet formation, one of the critical obstacles during the fermentation processes of filamentous fungi, an investigation was focused on the culture conditions(media and initial inoculum) and additives(soils, surfactants and polyethylene glycol 200) when a high phosphate-dissolving fungus, Penicillium sp. GL-101, was cultured in liquid media. Culturing the strain in PDB, SDB and YPD media, their pellet sizes decreased to the order of YPD > SDB > PDB. And at the high concentrations of the initial inoculum in the range from
유리인산 생성균 Penicillium sp. GL-101의 액침배양증 mycelial pellet 형성을 억제하기 위하여 배양조건(배지 종류, 초기접종량)과 배지 첨가물(점토광물, 계면활성제, PEG 200)의 종류에 따라 pellet 형성에 미치는 영향을 조사하였다. 그결과 이 균주는 배지종류를 달리하여 배양했을 때 YPD > SBD > PDB 순으로 pellet 크기가 감소하였다. 또한 이 균주는
