摘要 紫菜作为一种大型红藻,是目前世界上人工栽培经济价值最高的一种栽培海藻。全世界人工栽培海藻的总产值近3×10~9美元,其中紫菜的产值近2×10~9美元,约占2/3(费修绠等,1998)。紫菜不仅含有丰富的蛋白质、碳水化合物,而且各种维生素和矿物质的含量也特别丰富(Ruperez et al.,2002;Dinabandhu et al.,2002),其中紫菜的多糖及藻胆蛋白等成分具有药用价值,以紫菜为原料从中提取高附加值的产品。因此,利用紫菜可以开发保健食品和生物药物,其具有很大的市场价值和开发潜力。 Vegetative cells of Porphyra haitanensis sporophytes were grown in a bubble-column and a draft-tube internal-loop airlift bioreactor at 20℃with an illuminance of 40μmol photons m^(-2)s^(-1) for 20days.The draft-tube internal-loop airlift bioreactor yielded maximum cell density of 4850mg DCW(Dried Cell Weight)/L and higher growth rate of 0.094/d,compared to the bubble-column,3950mg DCW/L and 0.086/d,respectively.The advantages were related to the more homogeneous fluid dynamic characteristics in the draft-tube internal-loop airlift bioreactor than the bubble-column bioreactor.
