- Аннотация: Apart from their functions in the nervous system of animals, neurotransmitters operate as regula-tory agents and signals in diverse kingdoms of life. Some neurotransmitters at low concentrations haverecently been revealed to exert specific effects on microalgae, predominantly functioning as algal growthstimulators. This article presents new data on the effects of such neurotransmitters as serotonin, norepineph-rine, dopamine, histamine, and acetylcholine on the fatty acid and pigment composition of the greenmicroalga Scenedesmus quadricauda (Turp.) Breb. K-1149. It was established that acetylcholine and, to alesser extent, histamine increased the total fatty acid content of S. quadricauda cells, whereas serotonin anddopamine decreased the fatty acid content. Acetylcholine, histamine, and norepinephrine elevated the per-centage of polyunsaturated fatty acids; in contrast, serotonin and dopamine increased the share of saturatedfatty acids. Acetylcholine and, to a lesser extent, norepinephrine increased the total chlorophyll content pergram of dry weight in S. quadricauda, while histamine decreased the chlorophyll content. Histamine alsoincreased the chlorophyll a/chlorophyll b and carotenoid/chlorophyll ratios, which were decreased by dopa-mine. The data obtained are of biotechnological and ecological interest. The stimulation of fatty acid accu-mulation and the increase in the percentage of polyunsaturated species was caused by the neurotransmittersacetylcholine and histamine at low (1–10 μM) concentrations, which potentially enables facilitating the bio-technological production of health-promoting preparations for therapeutic and cosmetic purposes. However,other neurotransmitters (dopamine and serotonin) tested increased the relative content of saturated fattyacids; therefore, they apparently can be used to stimulate biofuel production, since saturated fatty acid–richlipids are advantageous raw materials for biodiesel production. The impact of neurotransmitters on themicroalgal fatty acid composition and photosystem components may be considered in terms of the ongoingchemical interaction between microalgae and other aquatic ecosystem components that are known to pro-duce neurotransmitters.
