Abstract Coccolithophores are important oceanic primary producers not only in terms of photosynthesis but also because they produce calcite plates called coccoliths. Ongoing ocean acidification associated with changing seawater carbonate chemistry may impair calcification and other metabolic functions coccolithophores. While short‐term effects on properties have been examined a variety coccolithophore species, long‐term adaptive responses scarcely documented, than for the single species...
Iron is a limiting factor that controls the phytoplankton biomass of ocean and plays an important role in lipid production microalgae. Elucidating effects different iron valences on microalgae helpful for their commercial production. We investigated growth, photosynthesis, fatty acid profile model diatom Phaeodactylum tricornutum cultured with depleted Fe, Fe2+, Fe2+/Fe3+, Fe3+. Samples were taken every 24 h 8 days, cell density, photosynthetic pigment content, chlorophyll fluorescence,...
Abstract. Marine phytoplankton such as bloom-forming, calcite-producing coccolithophores, are naturally exposed to solar ultraviolet radiation (UVR, 280–400 nm) in the ocean's upper mixed layers. Nevertheless, effects of increasing carbon dioxide (CO2)-induced ocean acidification and warming have rarely been investigated presence UVR. We examined calcification photosynthetic fixation performance most cosmopolitan coccolithophorid, Emiliania huxleyi, grown under high (1000 µatm, HC; pHT:...
The growth of phytoplankton and thus marine primary productivity depend on photophysiological performance cells that respond to changing environmental conditions. South China Sea (SCS) is the largest marginal sea western Pacific plays important roles in modulating regional climate carbon budget. However, little has been documented characteristics SCS. For first time, we investigated assemblages northern (NSCS) using a real-time in-situ active chlorophyll fluorometry, covering 4.0 × 105 km2....
Gephyrocapsa oceanica is a widespread species of coccolithophore that has significant impact on the global carbon cycle through photosynthesis and calcium carbonate precipitation. We investigated combined effects light (50 μmol m−2 s−1, 190 400 s−1) nitrogen sources its physiological performance under nitrogen-limited conditions. The specific growth rate was highest at mid-range level where it further accelerated by relative to . There were no differences between - -grown cells two levels...
The wastewater generated from monosodium glutamate production displays distinctive features of elevated salinity, organic content, as well nitrogen and phosphorus concentrations, its indiscriminate disposal poses a significant threat to water quality can cause detrimental impacts on aquatic ecosystems. application microalgae for (MSGW) treatment result in simultaneous purification biomass recovery. In this study, the algae species capable thriving diluted MSGW were screened, composition...
We examined the physiological performance in most cosmopolitan coccolithophorid, Emiliania huxleyi and Gephyrocapsa oceanica, which were treated with 8.3 (ambient O 2 (AO)), 4.6 (medium (MO)), 2.5 (low (LO)) mg L –1 under 400 ppm CO (AC)) 1000 (high (HC)) conditions. Elevated decreased specific growth rate of cells cultured AO LO conditions both species, but it increased MO-grown E. huxleyi. Regardless levels, diminished concentration inhibited while accelerating G. oceanica. reduced...
Kelps provide critical services for coastal food chains and ecosystem, they are important source some segments of human population. Despite their ecological importance, little is known about long-term impacts elevated CO
Phytoplankton are exposed to different concentrations of nutrients in waters along with changing light levels during diurnal and seasonal cycles. We grew the coccolithophorid Gephyrocapsa oceanica semi-continuously at nitrate under indoor low outdoor high conditions, found that reduced availability significantly increased its production particulate inorganic carbon (PIC), growth being reduced. High treatment suppressed nitrate-limited cells their efficiency N assimilation by up 63% compared...

We examined calcification photosynthetic carbon fixation performance most cosmopolitan coccolithophorid, Emiliania huxleyi, grown under high (1000 μatm, HC; pHT: 7.70) low (400 LC;...
The diatom Phaeodactylum tricornutum, known for its high triacylglycerol (TAG) content and significant levels of n-3 long chain polyunsaturated fatty acids (LC-PUFAs), such as eicosapentaenoic acid (EPA), has a limited ability to utilize exogenous organic matter. This study investigates the enhancement acetate utilization in P. tricornutum by introducing an transport protein. transporter gene ADY2 from Saccharomyces cerevisiae endowed organism with capability assimilate accelerating growth....
Abstract. The individual influences of ocean warming and acidification on marine organisms have been investigated intensively, but studies regarding the combined effects both global change variables natural phytoplankton assemblages are still scarce. Even fewer addressed possible differences in responses communities pelagic coastal zones to acidification. We conducted shipboard microcosm experiments at off-shore (SEATS) near-shore (D001) stations northern South China Sea (NSCS) under three...
