빛의 파장에 따른 광합성 미세조류의 성장 = The growth of photosyntheic nicroalgae according to wavelength

다국어 초록 (Multilingual Abstract)

The growth of photoautotrophic organism such as microalgae occurs through photosynehesis in which light is the basic limiting factor in terms of photobiology and photobiotechnology. The light harvesting pigments found in microalgae are chlorphyll, phycobiliprotein and carotenoid. The concentration of photosynthetic pigments and growth are effected by the environment-specifically, photonflux density. Therefore, adaptations of microalgae to photon flux density were studied and compared in Chlorella vulgaris and Spriulina platensis.
Chlorella vulgaris and Spirulina platensis were cultured under illumination of red, green, blue, and white spectrum light with equivalent photon flux density(77 μ Em??s?? between 400 and 700nm). Cultures of Cholorella vularis grown under red, green, blue and white light expressed similar maximum specific growth rates (1.3842 day??, 1.3250 day??, 1.4226, 1.4609 day??, respectively).
However, maximum specific growth rates of spirlina platensis in red(0.8142 day??) and white (0.7493 day??) light-grown culture were higher than those in green (0.4404 day??) and blue light (0.4485 day??). Since phycobiliproteins aborbed and orange light were associated with photosystemⅡ and transfered absorbing light energy predominatly to photosytem Ⅱ, red and white light including light-absorbing spectrum of phycobiliprotein were effective for growth of Spirulina platensis.
