Jeffrey, S.W., Structural relationships between algal chlorophylls, in Phytoplankton Pigments in Oceanography Guidelines to Modem Methods, Jeffrey, S.W., Mantoura, R.F.C. and Wright, S.W., Eds., UNESCO, Paris, 1997, 566. [Pg.45]

Mantoura, R.F.C. and Llewellyn, C.A., The rapid determination of algal chlorophyll and carotenoid pigments and their breakdown products in natural waters by reversed-phase high-performance liquid chromatography, A a/. Chim. Acta, 151, 297, 1983. [Pg.445]

The toxic substance is a pyrophenophorbide a derivative of algal chlorophyll which causes photosensitization. [Pg.39]

Shoaf and Lium [103] used thin layer chromatography to separate algal chlorophylls from their degradation products. Chlorophyll is extracted from the algae with dimethyl sulphide and chromatographed on commercially available thin layer cellulose sheets, using 2% methanol and 98% petroleum ether as solvents, before determination by either spectrophotometry or fluorometry. [Pg.241]

Measured end points are photosynthesis as the incorporation of radiolabelled H C03 ( C) and bacterial activity as the incorporation of radiolabelled thymidine (thym) fluorometric measurements basal fluorescence (Fo) and photon yield (Y) chlorophyll-a concentration (chl-a) species composition (spp) and the biovolume of algae obtained after algal counting (biovolume)... [Pg.48]

Whereas the biosynthesis of chlorophylls a and b in higher plants has been described in detail, the synthesis and regulation of related substances found in less well-known algal groups and lower plants are largely unknown and will be areas of scientific interest in the future. Different and new types of chlorophylls and related substances have been reported and little is known about their possible biological... [Pg.37]

Algae colonize both natural (cobbles and sediments, macrophytes and wood) and artificial substrata (walls, infrastructures). Light attenuation limits the development of the algal community to the shallow areas of the river. Benthic chlorophyll in the... [Pg.129]
