Fundamental growth characteristics of non-transformed rice cell and genetically modified rice cell have been studied to evaluate their potential as a host system for recombinant protein production. Specific growth rate in 5l fermenter was about 0.41 liter per day for both the non-transformed cell and the genetically modified cell with initial sucrose concentration 30g/l. Although the specific growth rate of the genetically modified cell was almost the same as that of the non-transformed cell, period of log-phase was shorter than that of the non-transformed cell. While growth yield of the non-transformed rice cell was 0.38 for initial sucrose concentration of 30g/l, those values were larger than 0.5 for initial sucrose concentrations 10 and 15g/l. The growth yield of the genetically modified cell was 0.19 for initial sucrose concentration of 30g/l. Dry cell weight of the genetically modified rice cell reached 12g/l in 5l fermenter. It was found that kinetin concentration decreased rapidly, and ammonia was produced in culture medium during cell culture.
