摘要:
纤细角毛藻(Chaetoceros gracilis)具有丰富的营养组成,是重要的生物饵料微藻。该试验以f/2培养基中标准的氮磷供给水平为基准,进行不同氮磷供给水平对纤细角毛藻生长及细胞物质组成的研究。结果表明,基准浓度的1/2倍及以下的低氮供给使纤细角毛藻的生物量减少严重,而基准浓度的2倍、3倍高氮供应下仍与基准氮供给相差不大。高于基准磷浓度供给促进纤细角毛藻的生长,其中基准磷浓度的3/2倍最优。在提高纤细角毛藻生物量产量方面,改变磷供给浓度比氮更有效。在细胞物质组成方面,基准浓度的3/2-3倍的高氮供给是提升细胞蛋白质含量的有效手段,而磷浓度变化对蛋白质含量的影响较低。细胞总糖含量的提升可通过降低磷供给水平(1/8-1倍基准浓度)实现。降低氮供应至基准浓度的1/8~1/4倍或者降低磷供应至基准浓度的1/8~1/4倍的寡营养条件,均能有效提高细胞脂肪含量,其中1/8倍的磷供给浓度对于提高脂肪含量效果最好。综合而言,纤细角毛藻的生长和细胞物质组成受磷营养供给的影响大于氮供给。
