Development of microbial community during Skeletonema costatum detritus degradation

Hydrobiologia, 1997
Microbial degradation of algal detritus was studied experimentally using the diatom Skeletonema costatum prekilled culture as a substrate for the marine microbial community. The qualitative and quantitative changes in the microbial community and the algal detritus structure were followed during 11 days of incubation at the water temperature of 20 °C.

Effects ofSkeletonema costatumExtracts on the Central Nervous System

Planta Medica, 1992
We report the effects of aqueous extracts of the microalga Skeletonema costatum Greve (Cleve) (Bacillariophyceae) on spontaneous motor activity, rectal temperature, motor coordination, amphetamine-induced hypermotility, exploratory behaviour, muscle relaxation, catalepsy, conditioned avoidance responses, oxotremorin-induced cholinergic syndrome, and ...

Microalgae Skeletonema costatum for Cd and Cu Remediation

Asian Journal of Water, Environment and Pollution, 2020
Cadmium (Cd) and copper (Cu) are types of heavy metals that can have an adverse effect on the ecosystem. Even copper is an essential metal but in limited concentrations, however, it leads to a toxic effect on the environment when used in high concentrations. Bioremediation of these metals can be done using microalgae Skeletonema costatum.

Combination of ocean acidification and warming enhances the competitive advantage of Skeletonema costatum over a green tide alga, Ulva linza.

Harmful Algae, 2019
Red tide and green tide are two common algal blooms that frequently occur in many areas in the global oceans. The algae causing red tide and green tide often interact with each other in costal ecosystems.

Carbohydrate metabolism in the marine diatom Skeletonema costatum

Marine Biology, 1969
This is a study on the metabolism of the algal biochemical constituents of a marine diatom, Skeletonema costatum. The carbohydrates, protein, and lipid, of the diatom grown under light and dark conditions were analyzed. The composition of the organic compounds did not vary in the alga grown under continuous light conditions throughout the experiment ...

Mitigation effects of CO2-driven ocean acidification on Cd toxicity to the marine diatom Skeletonema costatum.

Environmental Pollution, 2019
Ocean acidification (OA) is a global problem to marine ecosystems. Cadmium (Cd) is a typical metal pollutant, which is non-essential but extremely toxic to marine organisms. The combined effects of marine pollution and climate-driven ocean changes should

Characterization of allelochemicals of the diatom Chaetoceros curvisetus and the effects on the growth of Skeletonema costatum.

Science of the Total Environment, 2019
Allelopathy has been regarded as chemical weapons for marine phytoplankton that enhanced competition ability in stressful conditions, especially during blooms.

Inhibitory effects of Skeletonema costatum on mercury methylation by Geobacter sulfurreducens PCA.

Chemosphere, 2019
Algae and mercury (Hg) are ubiquitous in marine environments. In this study, we investigated the effects of a typical marine algae of diatom Skeletonema costatum on Hg methylation by an iron-reducing bacterium of Geobacter sulfurreducens (G ...

Reassessment of lipid composition of the diatom, Skeletonema costatum

Phytochemistry, 1995
In the present work, we questioned the natural or artifactual origin of the large amounts of free fatty acids recovered in lipids from the diatom Skeletonema costatum. Using rapid cell harvest and a very drastic method to extract the lipids, we demonstrated that these lipid patterns rich in free fatty acids were relevant to the degradation of complex ...
