摘要:
采用正交实验的方法 ,对影响纤细角毛藻(Chaetoceros gracilis)生长的主要营养因素进行了优化 ,获得了以海水为基础的优化培养基配方: NaHCO3 0.15g/L, Na2SiO3(9H2 O0.20g/L, NaNO3 1.00g/L, KH2PO4 0.02g/L, VB1 2.7mg/L, VB12 1.5μg/L。实验表明 ,用该优化配方培养纤细角毛藻具有生长速度快、产量高的显著优势 ,为该微藻在光生物反应器中的进一步高密度培养提供了良好条件。

Optimization of culture condition for Chaetoceros gracilis
Abstract:
Major nutrient factors were optimized by means of orthogonal tests. The optimum medium was obtained NaHCO3 0. 15g / L, Na2SiO3·9H2O 0. 20 g / L, NaNO3 1. 00g / L, KH2PO4 0. 02 g / L, VB1 2. 7 mg / L, VB12 1. 5μg / L, which evidently increased the growth speed and cell biomass productivity of Chaetoceros gracilis compared to well - known medium f / 2. The new redia established a basis for high density culture of Chaetoceros gracilis in airlift loop photobioreactor.
