利用红色发光二极管（LED）对雨生红球藻（Haematococcus pluvialis）进行了培养（λ（max）= 625 nm），绿色（λ（最大值）= 525 nm），蓝色（λ（max）= 470 nm），蓝紫色（λ（max）= 410 nm）和紫色（λ（max）= 380 nm）光和荧光灯，研究了波长对细胞生长和虾青素积累的影响。发现发射短波长（380-470 nm）的光的LED诱导每个干细胞高达5-6%的虾青素积累，尽管该诱导导致细胞生长的抑制。根据这些结果，我们提出了一种新的培养H。在不诱导高水平的虾青素积累的情况下，在用红色LED照射雨生藻的情况下，然后切换到用蓝光LED以高光强度照射以诱导高水平的虾青素积累。(C)2004年爱思唯尔公司All rights reserved.
The photosynthetic microalga Haematococcus pluvialis, a potential source of astaxanthin, was cultivated under illumination with LEDs emitting red (lambda(max) = 625 nm), green(lambda(max) = 525 nm), blue (lambda(max) = 470 nm), blue-purple (lambda(max) = 410 nm) and purple (lambda(max) = 380 nm) light and a fluorescent lamp, and the effects of wavelength on cell growth and astaxanthin accumulation were studied. LEDs emitting light of short wavelengths (380-470 nm) were found to induce astaxanthin accumulation of up to 5-6% per dry cell, although the induction caused the suppression of cell growth. From these results, we proposed a new strategy of cultivating H. pluvialis under illumination with red LEDs without inducing a high level of astaxanthin accumulation, and then switching to illumination with blue LEDs at a high light intensity to induce a high level of astaxanthin accumulation.
