    Seawater carbonate chemistry and photoinhibition of the Picophytoplankter Synechococcus (2023)
    PANGAEA
    Details
    Publication Date: 2024-03-15
    Description: The marine picocyanobacterium Synechococcus accounts for a major fraction of the primary production across the global oceans. However, knowledge of the responses of Synechococcus to changing pCO2 and light levels has been scarcely documented. Hence, we grew Synechococcus sp. CB0101 at two CO2 concentrations (ambient CO2 AC:410 μatm; high CO2 HC:1000 μatm) under various light levels between 25 and 800 μmol photons m−2 s−1 for 10–20 generations and found that the growth of Synechococcus strain CB0101 is strongly influenced by light intensity, peaking at 250 μmol m−2 s−1 and thereafter declined at higher light levels. Synechococcus cells showed a range of acclimation in their photophysiological characteristics, including changes in pigment content, optical absorption cross section, and light harvesting efficiency. Elevated pCO2 inhibited the growth of cells at light intensities close to or greater than saturation, with inhibition being greater under high light. Elevated pCO2 also reduced photosynthetic carbon fixation rates under high light but had smaller effects on the decrease in quantum yield and maximum relative electron transport rates observed under increasing light intensity. At the same time, the elevated pCO2 significantly decreased particulate organic carbon (POC) and particulate organic nitrogen (PON), particularly under low light. Ocean acidification, by increasing the inhibitory effects of high light, may affect the growth and competitiveness of Synechococcus in surface waters in the future scenario.

    Seawater carbonate chemistry and photosynthetic performance and N2 fixation in the marine cyanobacterium Trichodesmium (2023)
    PANGAEA
    Details
    Publication Date: 2024-03-15
    Description: Effects of changed levels of dissolved O2 and CO2 on marine primary producers are of general concern with respect to ecological effects of ongoing ocean deoxygenation and acidification as well as upwelled seawaters. We investigated the response of the diazotroph Trichodesmium erythraeum IMS 101 after it had acclimated to lowered pO2 (~60 μM O2) and/or elevated pCO2 levels (HC, ~32 μM CO2) for about 20 generations. Our results showed that reduced O2 levels decreased dark respiration significantly, and increased the net photosynthetic rate by 66 and 89% under the ambient (AC, ~13 μM CO2) and the HC, respectively. The reduced pO2 enhanced the N2 fixation rate by ~139% under AC and only by 44% under HC, respectively. The N2 fixation quotient, the ratio of N2 fixed per O2 evolved, increased by 143% when pO2 decreased by 75% under the elevated pCO2. Meanwhile, particulate organic carbon and nitrogen quota increased simultaneously under reduced O2 levels, regardless of the pCO2 treatments. Nevertheless, changed levels of O2 and CO2 did not bring about significant changes in the specific growth rate of the diazotroph. Such inconsistency was attributed to the daytime positive and nighttime negative effects of both lowered pO2 and elevated pCO2 on the energy supply for growth. Our results suggest that Trichodesmium decrease its dark respiration by 5% and increase its N2-fixation by 49% and N2-fixation quotient by 30% under future ocean deoxygenation and acidification with 16% decline of pO2 and 138% rise of pCO2 by the end of this century.

    Publication Date: 2024-03-15
    Description: Eutrophic coastal regions are highly productive and greatly influenced by human activities. Primary production supporting the coastal ecosystems is supposed to be affected by progressive ocean acidification driven by increasing CO2 emissions. In order to investigate the effects of high pCO2 (HC) on eutrophic plankton community structure and ecological functions, we employed 9 mesocosms and carried out an experiment under ambient (410 ppmv) and future high (1000 ppmv) atmospheric pCO2 conditions, using in situ plankton community in Wuyuan Bay, East China Sea. Our results showed that HC along with natural seawater temperature rise significantly boosted biomass of diatoms with decreased abundance of dinoflagellates in the late stage of the experiment, demonstrating that HC repressed the succession from diatoms to dinoflagellates, a phenomenon observed during algal blooms in the East China Sea. HC did not significantly influence the primary production or biogenic silica contents of the phytoplankton assemblages. However, the HC treatments increased the abundance of viruses and heterotrophic bacteria, reflecting a refueling of nutrients for phytoplankton growth from virus-mediated cell lysis and bacterial degradation of organic matters. Conclusively, our results suggest that increasing CO2 concentrations can modulate plankton structure including the succession of phytoplankton community and the abundance of viruses and bacteria in eutrophic coastal waters, which may lead to altered biogeochemical cycles of carbon and nutrients.

    Notes: Extrusion directly following vacuum infiltration is a special forming technique thatcombines the advantages of liquid metal infiltration and semisolid extrusion. The major advantages ofthis process are elimination of porosity and shrinkage, good surface finish, good dimensionalaccuracy, high strength to weight ratio and near net shaping. Magnesium matrix composites arefabricated usually through stirring casting, powder forming, injecting deposition, liquid metalinfiltration or die casting at present time. However few investigations on magnesium matrixcomposite are conducted for the specific characteristics of magnesium alloy, such as high chemicalactivity and easy oxidation. The present paper is focused on Csf/Mg composites obtained viainfiltration of porous short carbon fiber preform by liquid Magnesium. The complete experimentsetup is designed and fabricated by ourselves, which include the forming molds, the unit for meltingthe magnesium, the unit for vacuuming and the monitoring and collecting system of forming processparameters. In this method the whole experiment setup is vacuumed firstly. Then the pressurizednitrogen is used to infiltrate the magnesium melt through a porous preform of short carbon fibers.After the infiltration completed, the punch of the press extrude the magnesium-infiltrated preform outof the forming die to form the tubes or bars. X-ray diffraction (XRD), optical and SEM microscopeswere used to characterize the infiltration and the microstructure of fabricated composites. Thecompression test was used to characterize the mechanical properties of fabricated composites. Theresults show that the preform was infiltrated thoroughly by melt magnesium and the fabricated Csf/Mgcomposites have excellent mechanical properties compared with the magnesium alloys. Csf/Mgcomposites should be very promising candidates for automobile parts and portable electronicappliance parts in the future

    Notes: The residual stress distribution of microstructure about Cu-Fe-P alloy for leadframe is simulated by finite element method of elastic-plastics deformation. The effect of thedensity of Fe particle on residual stress is mainly analyzed. It is indicated that the larger thedensity of particle is, the larger residual stress in particle and matrix near the interface is, andthe larger stress difference between both the sides is. When the density of Fe particle is 35%and the compressive extent of cold rolling is 25%, in the X-direction, the stress variation ofthe Cu matrix is from compressive 900MPa to tensile 1480MPa, and stress of the Fe particleis about compressive 246MPa. The maximum residual stress gradient near the interfacebetween Cu matrix and Fe particle reaches 1726MPa. The bigger stress concentration andresidual stress will destroy the quality of the material. Even peelings on the surface occur. Sothe appearance of bigger Fe particle goes against the quality of the material, and it should beavoided as far as possible in the production of Cu-Fe-P alloy for lead frame

    Telomerase down-regulation does not mediate PC12 pheochromocytoma cell differentiation induced by NGF, but requires MAP kinase signalling (2005)

    Notes: Telomerase is a ribonucleoprotein complex that maintains chromosomal telomere homeostasis and underlies continuous renewal of stem cells and immortalization of neoplastic cells. Telomerase is down-regulated during cell differentiation, but the mechanisms of down-regulation are largely unknown. Here, we examined roles of mitogen-activated protein (MAP) kinase and phosphatidylinositol-3 (PI3) kinase signalling pathways in telomerase down-regulation triggered by nerve growth factor (NGF), and the role of telomerase down-regulation in NGF-induced neural differentiation in PC12 cells. We report that NGF-induced telomerase down-regulation requires MAP kinase signalling. While mutations of all putative Akt phosphorylation sites in telomerase reverse transcriptase (TERT) has no effect on telomerase activity, inhibition of MAP kinase signalling by PD98059 or U0126 abolishes NGF-induced telomerase down-regulation in a concentration-dependent manner. Reversal of NGF-induced telomerase down-regulation by TERT overexpression does not prevent NGF-induced neural differentiation. Down-regulation of telomerase by silencing TERT gene expression does not trigger cell differentiation in the absence of NGF, nor enhances NGF-induced differentiation. Thus, telomerase, withdraws by a mechanism at TERT gene transcription level involving MAP kinase signalling while cells cease proliferation and undergo differentiation. The withdrawal of telomerase is not required to mediate NGF-induced PC12 cell differentiation and re-establishment of telomerase activity at significant levels does not inhibit differentiation.

    Notes: Based on the intergenic sequences of Tri5–Tri6 genes involved in the mycotoxin pathways of Fusarium species, a generic PCR assay was developed to detect a 300 bp fragment of deoxynivalenol (DON)-chemotypes and a 360 bp sequence of nivalenol (NIV)- chemotypes of Fusarium graminearum. Mycotoxin chemotypes identified by the PCR assays were confirmed by the chemical analyses of HPLC or GC/MS. Further analysis of 364 F. graminearum isolates from 12 provinces of China showed that 310 were DON-chemotypes and 54 were NIV-chemotypes. Sequence analyses revealed that DON-chemotypes display more variations than NIV-chemotypes. This PCR assay could be used to detect mycotoxin-producing Fusarium-species and may thus help to develop strategies to avoid or reduce mycotoxin contamination of cereals. Also this assay may provide useful alternatives to antibody-based mycotoxin tests.
