Název v původním jazyce

Combined effect of CO2 and light on the N2-fixing cyanobacterium Trichodesmium IMS101: Physiological responses 1[OA]

Popis výsledku v původním jazyce

We examined the responses of Trichodesmium IMS101 grown under a matrix of low and high levels of pCO2 and irradiance. Growth rates as well as cellular carbon and nitrogen contents increased with increasing pCO2 and light levels in the cultures. The pCO2-dependent stimulation in organic carbon and nitrogen production was highest under low light. High pCO2 stimulated rates of N2 fixation and prolonged the duration, while high light affected maximum rates only. Gross photosynthesis increased with light butdid not change with pCO2. HCO3 was identified as the predominant carbon source taken up in all treatments. Inorganic carbon uptake increased with light, but only gross CO2 uptake was enhanced under high pCO2. A comparison between carbon fluxes in vivo and those derived from 13C fractionation indicates high internal carbon cycling, especially in the low-pCO2 treatment under high light
