Measurement of Cell Concentration of Fungal Broth Using Optical Density -Characteristics of Pellets-
흡광도를 이용한 곰팡이 배양액의 세포농도 측정 -Pellet의 특성에 관한 연구-
Abstract
A new method that considers the pellet sedimentation characteristics for fungal cell concentration measurement was developed using optical density. Appropriate mixing of the pellet suspension almost homogeneously was tried to prevent the sedimentation of the pellet by a small magnetic bar in cuvette, giving a stable optical density. The linear relationship between optical density and the dry cell weight was obtained. However, different curved lines were observed according to the pellet size. Optical density couldn't be detectable in the size range of
곰팡이 세포농도를 측정하기 위하여 pellet에 대한 침강 특성을 고려하여 홉광도를 측정하는 새로운 방법을 개발하였다
