Abstract
Aim: The investigation of the different culture systems in order to get high yield of baby hamster kidney (BHK) cell line. Materials and Methods: Different cultivation systems, vibrofermentor and 5-L stirred tank bioreactors, have been used for the production of BHK cell line. The production systems were evaluated with respect to pH, temperature, viable cell number, aeration rate and stirring speed. Results: BHK cells were successfully cultivated in vibrofermentor and stirred tank bioreactor (STR) systems. In addition, higher cell concentration was obtained with low aeration rate (0.005 vvm) comparing to those of 0.02 and 0.05 vvm. The cultivation in STR can be operated with low aeration rate due to decrease the expenditure and improve the cell productivity. Conclusion: In order to improve the cell yield of the anchorage semi-dependent cell line in pilot scale, it should be preferred that the cells are firstly adapted to suspension culture by vibrational stirring and then be cultivated in stirred tank bioreactor which is operated at low aeration rate. These results showed consistency with the previous studies.
