摘要

The influence of sugars in pre-cultivation media suspended plant cells on the kinetics of the sugar uptake and the ethanol production was studied by mid-infrared spectroscopy using a Fourier transform infrared spectrometer (FT-IR) equipped with an attenuate total reflection accessory (ATR). We performed the plant cell cultivation with Nicotiana tabacum cv. Bright Yellow No.2 (TBY-2) cells and Oryza sativa L., Japonica, cv. Nipponbare (rice) cells, respectively, in pre-culture and culture media, which had various types of glucose, fructose, sucrose or glucose-fructose mixtures. The results confirmed the kinetic differences between the TBY-2 cells and rice cells. These results suggested that the TBY-2 cells consumed sugar before growth and the rice cells consumed sugar after growth, moreover, the ethanol content increased just after cell growth was activated based on the non-dimensional cultivation time for the cell growth behavior.
