TAM III multi-channel calorimetry was applied to study the effect of different concentrations petroleum on soil microbial activity and community. The microbial activities of the soil samples were recorded as power-time curves. The thermokinetic parameters such as microbial growth rate constant k, total heat evolution Q(T), metabolic enthalpy ∆H (met) and mass specific heat rate J(Q/S) were calculated. Results showed that petroleum had a certain extent effects to soil microorganisms. The results indicate that the soil microbial activity was promoted with a petroleum concentration lower than 0.52 % ± 0.24 %, but inhibited with further increase in petroleum.
TAM III 多通道量热仪被应用于研究不同浓度石油对土壤微生物活性和群落的影响。土壤样品的微生物活性被记录为功率-时间曲线。热动力学参数，如微生物生长速率常数 k、总热量演化 Q(T)、代谢焓 ∆H(met)和质量比热率 J(Q/S)，被计算出来。结果表明，石油对土壤微生物有一定程度的影响。结果表明，当石油浓度低于 0.52%±0.24%时，土壤微生物活性得到促进，但当石油浓度进一步增加时，微生物活性受到抑制。
