Amino acids composition of some lichen species in taiga zone of European North-East of Russia

Data on amino acids content in the thalli of 19 lichen species in the middle taiga on the territory of the Komi Republic were presented. The protein and free amino acids content in dry weight of thalli was 100 and 2 mg/g respectively. Cyanolichens were characterized by a high content of protein amino acids, than that of chlorolichens. The correlations between the nitrogen and amino acids content were revealed. There is the positive association of the protein amino acids content with the photobiont type. The obtained results expand and deepen the traits of the lichen biota in the taiga zone of European North-East of Russia.
