Краткое описание

The paper deals with the effect of glucose on the growth and pigment composition of two species of blue-green algae, Nostoc linckia (Roth) Bom. et Flah. and Spirulina platensis (Nordst.) Geitl. The algae are shown to be able to change to mixotrophic growth. Incorporation of glucose into the algal metabolism was accompanied by a 2-5-fold increase in the biomass and photosynthesis repression. The influence of glucose on the pigment composition of the studied algae was considerably different: glucose induced a marked reduction of all S. platensis pigments, whereas the content of N. linckia pigments did not change, or in some cases it even increased. The most considerable decrease in me content of S. platensis pigments was observed in the presence of 1 % glucose on the 4th day of growth: the phycocyanin and chlorophyll were 2-2.7 times lower, and allophycocyanin and earotenoids were 1.7-2 times lower than in the control. It was found that the change of S. platensis and N. linckia to mixotropic growth caused excretion of coproporphyrm into the culture medium. An assumption is advanced that glucose blocks the biosynthetic pathway of tetrapyrroles at the level of coproporphyrins, while light stimulates the formation of earlier precursors of γ-aminolevulinic acid.
