摘要

The analysis of а and b chlorophylls, β-carotene, and xanthophylls in the cells of green algae-photobionts from genera Asterochloris, Myrmecia, Trebouxia and Trentepohlia had shown the heterogeneity of their pigment content both on generic and specific levels. For genera Trebouxia and Myrmecia pigment content was identified for the first time. It was revealed that quantity and ratio of pigments in the species of genus Trebouxia belonging to different morpho-ecological groups are unequal. Low (β-carotene - up to 0.8 mg/100 g and xanthophylls - up to 2.5 mg/100 g of green biomass in the groups «corticola» and «impressa») or high (β-carotene - up to 7.2 mg/100 g and xanthophylls - up to 15.8 mg/100 g of green biomass in groups «arboricola» and «simplex») content of carotenoids probably applies to ecological and physiological characteristics of certain species, in particular, their status as obligate or facultative photobiont, geographical distribution, etc. Obtained data on pigment composition of Asterochloris, Myrmecia and Trentepohlia confirm similar trends in changing of the quantity and ratio of various groups of pigments depending on life strategy, ecology and geographical distribution of the species.
