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.

采用热重-差热联用技术对微生物进行了研究，探讨了利用热重技术筛选产油微生物的可能性。采用质量差基线法研究了产油微生物和非产油微生物的热行为。为了分辨重叠的DTA峰，检查了用于区分产油和非产油微生物的两步线性温度程序。当该方法应用于微生物时，在280至360 ℃的温度范围内检测到产油微生物和非产油微生物之间的热能的显著差异。
