Periphyton pigment analyses using paper chromatography

摘要: Paper chromatography was used to study the community structure, proportion of degraded chlorophylls total pigment content, and chlorophyll carotenoid content epilithic periphyton algae from Lake Tahoe, California-Nevada. Analyses were made using both samples directly lake cultured periphytic algae. The extraction with boiling 100% methanol; two dimensional separate pigments. relative contribution different fractions light absorption by complete extract estimated planimetric integration curves. From estimates proportions algal groups in samples. Further, results gave information on active degradated forms a, as well a per unit biomass. showed rarity phaeophytin communities but often some occurred other degradation products. percentage varied according environmental conditions, productivity vitality
