Plant-based recombinant protein production systems are powerful tools that can be used instead of microbial and animal cell culture systems. The aim of this study was to establish a stable brazzein production system from carrot cell suspension using bioreactor. Using Agrobacterium-mediated transformation (stress-inducible SWPA2 promoter and brazzein gene), three transgenic lines (TC1, 11, 12) were generated. During the TC12 culture period, cell proliferation increased rapidly up to 15 days, and the maximum cell division rate (log phase) was reached after 6 days of culture. Fresh weight peaked at day 18, 3.8-fold (7.6 g 100 mL?1) higher than on day 1, and gene expression was tenfold higher on day 27 than on day 0. The brazzein-encoding gene was also analyzed after treatment with various stress factors for increase of brazzein gene expression, and abscisic acid (ABA) and hydrogen peroxide ( H2O2) proved most effective. In particular, the gene expression was enhanced 2.5-fold with 220 μM H2O2 and 2.8-fold with 50 μM ABA, compared with controls. Transgenic cells were then transferred to various types of air-lift bioreactor, and the column bioreactor achieved a higher biomass (238.9 g L? 1) than cone and balloon bioreactors. These results demonstrate an efficient protein production system for brazzein using an air-lift bioreactor that may be suitable for the use in the food industry.
