Effect of bioreactor configuration on the growth and maturation of Picea sitchensis somatic embryo cultures
2000
Ingram, B. | Mavituna, F.
Somatic embryo suspension cultures of Picea sitchensis (Sitka spruce) derived from two cell lines, SS03 and SS10, wee grown in shake flasks, air-lift, bubble, stirred tank and hanging stirrer bar bioreactors. Cell line SS03 yielded freely suspended and individual stage 1 embryos, while the embryos of SS10 were present in large aggregates. Compared to shake flasks, proliferation in bioreactors resulted biomass; however, cell line morphology influenced the effect of different bioreactors were matured on gelled solid medium and in submerged culture where gelled solid medium was covered with a layer of liquid medium. The number of stage 3 (mature) embryos produced from SS03 in the bubble bioreactor was significantly higher than those from stirred tank and hanging stirrer bar bioreactors with both solid medium and submerged culture. Submerged culture was unsuitable for SS10 embryo maturation.
