Abstract
An experimental study has been carried out to investigate the effectivenes of several reduced serum and serum-free media for the cultivation of an ovarian cell line, Bm5, of the lepidopteran insect Bombyx mori. Bm5 cell were successfully adapted to grow in a medium containing 5% serum and a serum-free medium (EX-CELL 400). On the other hand, this cell line could not be adapted to grow in several other media suggested in the literature, including IPL-41 + 2% fetal bovine serum (FBS), SF-900, and a serum-free medium (ISFM). Furthermore, a comparative study was conducted to determine the production levels of B. mori nuclear polyhedrosis virus (BmNPV) in Bm5 cells cultured in three different medium formulations. The production levels of BmNPV in adapted Bm5 cells grown in a 5% serum-supplemented medium and a serum-free medium (EX-CELL 400) were comparable to those obtained in Bm5 cells grown 10% serum-supplemented medium. © 1992 John Wiley & Sons, Inc.
