Evaluation of four types of inhibition for modelling the influence of carbon dioxide on oxygen consumption of fruits and vegetables

摘要: Abstract High carbon dioxide (CO 2 ) concentrations can reduce the oxygen (O consumption rate of a number fruits and vegetables. This reduction be modelled by four types inhibition in an enzyme kinetics model: (1) competitive type; (2) uncompetitive (3) combination both previous types; (4) non-competitive type. These different were tested for describing CO influence on O using experimental data supplemented with from literature. The gas exchange rates apples (cv. Golden Delicious Elstar), asparagus, broccoli, mungbean sprouts cut chicory measured under wide range concentrations. With used, no was found apples. There clear high other produce. A good estimation C could obtained models. supports use Michaelis-Menten modelling consumption. Depending product statistical analysis gave results type inhibition. Based only, distinction between made. It suggests simultaneous existence idea is that combined equation most closely related to what actually occurring plant tissues. However, reasons simplicity preferred, showing similar inhibition, giving all products tested.
