IRON AVAILABILITY BY COASTAL DIATOM CHAETOCEROS SP. IN THE SHIZUGAWA BAY, JAPAN
Proceedings of International Conference "Managinag risks to coastal regions and communities in a changinag world" (EMECS'11 - SeaCoasts XXVI), 2017 This study aimed to investigate the spatial distribution of dissolved iron from river to coastal waters and iron bioavailability for coastal phytoplankton. Dissolved iron concentrations and other water quality parameters (e.g., pH, concentrations of dissolved organic carbon and trace metals, etc.) were determined in the Shizugawa Bay and its adjacent ...

Mixotrophic culture of Chaetoceros sp. and the synergistic carbon and energy metabolism
Bioresource Technology, 2023This research studied the metabolic mechanism of the mixotrophic Chaetoceros sp. The results showed this alga had the highest cell density and growth rate of 47.72 × 105 cells mL-1 and 0.41 d-1, respectively, with a maximum dry weight of 2.90 g/L, when compared to photoautotrophic and photoheterotrophic modes.

Stable nuclear transformation of the diatom Chaetoceros sp.
Phycological Research, 2011SUMMARYA nuclear transformation system for the centric diatom Chaetoceros sp. has been established using two plasmids pTpfcp/nat and pTpNR/green fluorescent protein (GFP) that had been used for Thalassiosira pseudonana transformation. These contain the nourseothricin resistance gene (nat) with the fucoxanthin chlorophyll a/c binding protein (fcp ...

The chemical composition of Chaetoceros sp. (Bacillariophyceae) under different light conditions
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1994Abstract Chaetoceros sp. growth with white, pure blue and mixed blue light in 10-1 semicontinuous culture with 50% daily dilutions was light-limited at photon flux densities of 199 μmol m−2 s−1. At the above light level the type of light did not cause variations in protein content, but the use of mixed blue (192.5 μmol m−2 s−1 of blue, and 6.5 of ...

Microalgae can produce various natural products such as pigments, enzymes, unique fatty acids and vitamin that benefit humans. The objective of the study is to study the bioaccessibility of carotenoids (β-carotene and lycopene) and vitamin E (α- and β-tocopherol) of Nannochloropsis oculata and Chaetoceros calcitrans.

Abstract The diatom Chaetoceros sp. was grown with a continuous photon flow rate of 125 μmol m −2 s −1 , provided by Cool White (CW), or by Gro-Lux and Gro-Lux wide spectrum agricultural lamps (GRO and GRO/WS). At the end of exponential and during stationary growth, these gave higher cell numbers and biomass than CW lamps.

To understand the diversity of the diatom genus Chaetoceros Ehrenberg, the C. lorenzianus complex was previously chosen as a model and three new species were described. In the present study, yet another new species, Chaetoceros pauciramosus sp. nov., was discovered from Chinese tropical waters and the temperate south-eastern Baltic Sea.
