“…affect the quantity and proportion of chlorophyll a and other major light absorbing accessory pigments [1,55]. Changes are generally speciesspecific and may vary under different growth conditions [2]. As discussed earlier, under light limiting conditions, a common response of microalgae would be to increase the number or size of its lightharvesting units.…”

“…Many recent studies have shown that microalgae grown under monochromatic blue or red light exhibited similar or enhanced growth and productivity rates when compared to that of multi-chromatic white light [1][2][3]36]. By using selective wavelengths of incident light which are complementary or at least close to the maximum absorption of microalgae pigmentation, the use of other wavelengths which are poorly absorbed by the alga is avoided [1,27].…”

“…The significant production of PE over the full range of blue-red light would help maintain the level of photosynthesis over a wide range of depths and could also aid in the protection from high light intensity in surface waters (LopezFigueroa & Niell, 1990;Subramaniam et al, 1999). It has been suggested that changes in pigment composition with increasing depth are largely responses to low irradiance rather than to spectral quality (Aidar et al, 1994). However our study suggests that light quality also has a significant effect on the concentration of photosynthetic pigments and hence growth.…”

The influence of light intensity and light quality on the growth, N 2 fixation and pigmentation of cultures of the cyanobacterium Trichodesmium GBRTRLI101 were investigated under defined laboratory conditions. Both growth rate and N 2 fixation rate were strongly dependent on light intensity. The N 2 fixation rate increased with light intensity over the whole range tested (PAR 10-160 lmol quanta m )2 s )1 ) but the growth rate passed through a maximum in the range 45-75 lmol quanta m )2 s )1 . Growth rates were the highest under white and yellow light and were significantly reduced under red light. The results also showed that the cellular concentrations of chlorophyll a and phycobiliproteins (PBPs) increased under low light conditions and were affected by light quality. Overall the results suggest that the availability of light and the quality of that light play an important role in the growth and distribution of Trichodesmium in coastal and oceanic waters.

“…Growth rates of An?phidiuium and Bidduljdiin were slower under red light than green, white, or violet light at 80 kmol photons.m-2.s-' (Humphrey 1983). T h e diatom Cyclotelln caspin grew faster under blue-green light than red light at 25 pmol photons.m-2.s-' (Aidar et al 1994). A study designed to distinguish between the effects of light quality and light quantity found that under equal PUR light quality did not affect growth rate in Thnlnssiosira rotuln or Dumliella tertiolectn (Rivkin 1989).…”

DOES LIGHT QUALITY AFFECT THE SINKING RATES OF MARINE DIATOMS?¹

Although the spectral quality of light in the ocean varies considerably with depth, the effect of light quality on different physiological processes in marine phytoplankton remains largely unknown. In cases where experiments are performed under full spectral irradiance, the meaning of these experiments in situ is thus unclear. In this study, we determined whether variations in spectral quality affected the sinking rates of marine diatoms. Semicontinuous batch cultures of Thalassiosira weissflogii (Gru.) Fryxell et Hasle and Ditylum brightwellii (t. West) Grunow in Van Huerk were grown under continuous red, white, or blue light. For T. weissflogii, sinking rates (SETCOL method) were twice as high (∼0.2 m·d−1)for cells grown under red light as for cells grown under white or blue light (∼0.08 m·d−1), but there were no significant differences in carbohydrate content (∼105 fg·μm−3) or silica content (∼ 17 fg·μ−3) to account for the difference in sinking rates. Thalassiosira weissflogii grown under blue light was significantly smaller (495 μm3) than cells grown under red light (661 μm3), which could contribute to its reduced sinking rate. However, cells grown under white light were similar in size to those grown under red light but had sinking rates not different from those of cells grown under blue light, indicating the involvement of factors other than size. There were no significant differences in sinking rate (∼0.054 m·d−1) or silica content (∼20 fg·μm−3) in D. brightwellii grown under red, white, or blue light, but cells grown under red light were significantly (20%) larger and contained significantly (20%) more carbohydrate per μm3 than cells grown under white or blue light. Spectral quality had no consistent effect on sinking rate, biochemical composition (carbohydrate or silica content), or cell volume in the two diatoms studied. The similarity in sinking rate of cells grown under white light compared to those grown under blue light supports the ecological validity of sinking rate studies done under white light.
