PRELIMINARY REPORT ON DIATOMS FROM SOUTH GEORGIA

open access: yesAntarctic Record, 1965
Diatoms of South Georgia were reported in four papers up to the present, one by P. F. REINSCH (1890), one by G. W. F. CARLSON (1913) and the remaining two by KO-BAYASHI (1963 and 1965).

Species Dynamics and Gene Expression in Algal Polycultures Under Mixotrophic Cultivation in Outdoor Pilot‐Scale Nordic Conditions

open access: yesBiotechnology and Bioengineering, EarlyView.
These results demonstrate that mixotrophic conditions drive both microbial community shifts and metabolic reprogramming, underscoring the importance of cultivation strategy and polyculture selection for targeted applications such as nutrient recovery and bioproduct generation.

Partners or passengers? Revisiting the association between diatoms and aquatic animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Patterns of diatom treatment in two coexisting species of filter-feeding freshwater gastropods

open access: yesKnowledge and Management of Aquatic Ecosystems, 2014
To assess trophic partitioning among sympatric gastropod species in ancient lakes, we quantified diatoms in the guts of two coexistent Baikal gastropod species and tested for differences in species, size, and fracturing of large and ...

Carbon‐Embedded Fe‐Cu Composite Oxide Nanoparticles Derived From Spindle‐Shaped Bimetallic MOFs for Selective Oxidation of Methane

open access: yesCarbon and Hydrogen, EarlyView.
Fe3Cu1/C (CuFe5O8) was synthesized by high‐temperature carbonization of FexCuyBDC MOF, which exhibited excellent catalytic performance for methane selective oxidation at 80°C. The synergistic effect between Cu and Fe in the derived Fe3Cu1/C (CuFe5O8) composite oxide inhibits deep oxidation compare to Fe/C (Fe3O4), and the reaction proceeds via a free ...

The effect of nutrient limitation and oxidative stress on bromoform production from axenic cultures of marine diatoms [PDF]

open access: yes, 2012
Includes bibliographical references.Bromoform is mainly produced naturally by marine organisms. The production by microalgae however is not well quantified, and the mechanism by which phytoplankton produce bromoform is not fully elucidated.
