中文摘要: 虾青素具有很强的抗氧化能力,雨生红球藻在目前已知生物中虾青素含量最高。该文采用响应面法研究温度、pH值、NaCl浓度、钨酸钠浓度对雨生红球藻虾青素积累的影响。结果表明,雨生红球藻虾青素积累的最佳工艺条件为温度27℃、pH 9.6、NaCl浓度1.7 g/L、钨酸钠浓度5.2 mmol/L。各因素对雨生红球藻虾青素积累影响的顺序为pH值>温度>钨酸钠浓度>NaCl浓度。
Abstract:Astaxanthin has strong antioxidant capacity.Haematococcus pluvialis is the living organism with the highest known astaxanthin content.In this study,the effects of temperature,pH value,NaCl concentration,and sodium tungstate concentration on astaxanthin accumulation in H.pluvialis were studied by response surface methodology.The results showed that the optimum conditions for astaxanthin accumulation in H.pluvialis were a temperature of 27 ℃,pH 9.6,NaCl concentration of 1.7 g/L,and sodium tungstate concentration of 5.2 mmol/L.The order of influence on the accumulation of astaxanthin in H.pluvialis was pH value>temperature>sodium tungstate concentration>NaCl concentration.
