Evaluation of a new microcarrier process in bioreactor in large-scale cultivation for hepatitis B vaccine

ZHANG Ying,XU Feng,ZHANG Ping,et al.(Lanzhou Institute of Biological Products,Lanzhou 730046,China)  
Bioreactor process for recombinant CHO-C28 cell cultivation of hepatitis B vaccine was investigated in this study.A piece of three dimensional polyester fiber discs was used as support material and a continuous perfusion mode was used for cultivation.The culture conditions such as inoculation of cell density,pH,DO and perfusion velocity were studied respectively.The continuous three run cultivations were performed,each run maintained for 60 days.The optimal culture conditions are in following pH 6.80~7.10,DO 20%~30%,temperature 36~37℃,perfusion velocity 138ml/h and inoculation cell density 1.9 106 cell/ml.The ultimate average titer for harvested culture is 1∶256 in RPHA,and the content of purified HBsAg is 0.912mg/L.Finally,the advantages and disadvantages for both culture systems of roller bottle and bioreactor were compared and summarized.
