Elucidation of the mechanism of suppression of respiration activity of fresh produces under modified atmosphere

通过测定不同温度和浓度下大豆幼苗的O_2消耗量和CO_2产出率，建立了改良大气条件下大豆幼苗呼吸速率的预测模型。开发了一个流通系统，并使用它来获取数据。观察到，基于Michaelis-Menten酶动力学的模型与我们的实验数据吻合良好。将模型扩展为Arrhenius型温度对动力学常数K_m和V_<max>的影响。本研究建立的模型能够预测不同温度和浓度下幼龄大豆的O_2消耗量和CO_2产出率。

In this study, O_2 consumption and CO_2 production rates of young soybean were measured under different temperatures and O_2 concentrations to develop the predicting model for respiration rate under modified atmospheres. A flow through system was developed and used to obtain data. It was observed that the model based on Michaelis-Menten enzymatic kinetics, which had been reported previously, was in good agreement with our experimental data. The model was expanded to describe the Arrhenius type temperature effect on the kinetic constants K_m and V_<max>. The model developed in this study will enable to predict O_2 consumption and CO_2 production rate of young soybean under various temperatures and O_2 concentrations.
