摘要:

本研究旨在探究LED光源在雨生红球藻培养中的优势,为规模化培养提供更优选择。相较传统荧光光源,LED在微藻产业的应用研究相对滞后。试验选取荧光和LED两种光源,分别设置800、1000、1200 lx等3个光照强度梯度,每个梯度设置3个平行,试验周期从接种开始持续到生长至稳定期共10 d。每天检测藻细胞密度并计算生长速率,隔天检测藻液OD680值和干重含量。结果表明:雨生红球藻在第1天~第3天均处于潜伏期,生长速率最大为0.082,第4天进入缓慢生长期,生长速率在0.110~0.232,第6 d进入指数增长期,生长速率为0.301~0.662;第7天后,同种光源下,雨生红球藻平均细胞密度、平均生长速率、OD680值和干重含量随着光照强度的增加而增加,相同光照强度下LED光源组的上述4个指标值大于荧光光源组。其中在第9天1200 lx的光照强度下,LED组的4个指标比荧光组高8.82%~16.97%。结果表明,LED光源较荧光光源对雨生红球藻的生长更有利,在1200 lx光强下能显著提高藻细胞密度和生物量积累,且因其普遍具有节能、低散热等特性,更适合用于雨生红球藻的培养。本研究为利用LED光源规模化培养雨生红球藻以高效获取虾青素等高价值产物,提供了理论依据和数据支持。

Abstract:

To study whether LED lights have more advantages in the cultivation of Haematococcus pluvialis, we selected two light sources, fluorescence and LED, and set three light intensity grades of 800 lx, 1000 lx and 1200 lx, respectively. During 10 days from inoculation to growth to stability period, the algae cell density and the growth rate were calculated every day, OD680 and dry weigh were examined every two days. The results showed that, H. pluvialis in each group was in the latent period from day 1 to day 3 with maximum growth rate of 0.082, grew slowly from day 4 with growth rate of 0.110-0.232, and entered the exponential growth period on day 6 with growth rate of 0.301-0.662; from day 7, with the increase of light intensity of both light sources, the average cell density, OD 680, dry weight and average growth rate increased, while with the same light intensity, the 4 indicators in LED light sources were greater than that in fluorescent light sources, which were greater 8.82%-16.97% in 1200 lx on day 9. Therefore, the LED light sources are more beneficial for the growth of Haematococcus pluvialis compared to fluorescent light sources, significantly increasing algal cell density and biomass accumulation under a light intensity of 1200 lx. LED light sources are more advantageous in cultivation of H. pluvialis, besides of energy saving and low heat dissipation, which are recommended to use. This study provides a theoretical basis and data support for the large-scale cultivation of Haematococcus pluvialis using LED light sources to efficiently obtain high-value products like astaxanthin.
