Аннотация: An important characteristic of a natural water body is the distribution of pigment composition of different groups of photosynthesizing organisms over depth and its variations in different seasons. Optical methods are widely used to monitor the concentrations of chlorophylls in algae or cyanobacteria in aqueous ecosystems, but they have very limited application in monitoring the bacteriochlorophyll (BChl) concentration in phototrophic bacteria. The paper describes comprehensively three new methods of quantitative analysis of the photosynthetic pigment of BChl d of green sulfur bacteria using spectral measurements in both initial samples of natural water (absorption spectra), and in pigment extracts in organic solvents (absorption and fluorescence spectra). A comparative analysis of the results from different methods is carried out using, as an example, natural water from the chemocline region in Lake Trekhtsvetnoe, one of the meromictic water bodies in the Kandalaksha Bay in the White Sea. Conclusions are drawn about the applicability conditions of different methods, their advantages and limitations. All three methods suggested have been proven to be efficient using, as an example, samples of natural water with BChl concentrations differing by orders of magnitude, from 5 to 5000 mg/m3.
