Quantitative Determination of Bacteriochlorophylls d and e in Extracts from Natural Water Samples with Simultaneous Presence of Green- and Brown-Colored Green Sulfur Bacteria

Аннотация

In the present work, separation and quantitative assessment of bacteriochlorophylls d and e of green sulfur bacteria (GSB) in lake water was attempted. The method developed reveals the ratio of green- and brown-colored GSB in natural water by measurement of absorption spectra of the pigments in the extracts from environmental samples.
