- Аннотация: A symbiotic unicellular chlorophyte Desmodesmus sp. IPPAS S-2014 capable of growth at extremely high CO2 levels prohibitive for the majority of other microalgae is an interesting model for studies of CO2 tolerance mechanisms and a promising organism for CO2biocapture. We studied the initial (0–60 min) phase of the acclimation of this microalga to an abrupt drop of pH of the medium sparged with air : 20% CO2 mixture. Acclimation of the culture to these conditions was accompanied by a sharp decline in photochemical activity of the chloroplast followed by its recovery with a characteristic time of 10–50 min. We hypothesize that acidification of the cultivation medium by dissolving CO2 plays a key role in the observed decline of the photochemical activity. Possible role of photosynthetic apparatus tolerance to abrupt acidification in overall high tolerance of symbiotic microalgae to extremely high CO2 levels is discussed.
