Research Abstract

The simultaneous thermogravimetry (TG) and differential thermal analysis (DTA) was applied to microorganisms to examine the potential of a thermal technique for screening oleaginous microorganisms. Thermal behaviours of oleaginous and non-oleaginous microorganisms were investigated by using the mass-difference baseline method. To resolve overlapping DTA peaks, a two-step linear temperature program was examined for discriminating oleaginous and non-oleaginous microorganism. When this method was applied to microorganisms, a marked difference in heat energy between oleaginous and non-oleaginous microorganisms was detected in the temperature range from 280 to 360 oC.
