Impact of silver nanoparticles on marine diatom Skeletonema costatum

Journal of Applied Toxicology, 2016
AbstractWhen silver nanoparticles (AgNPs) are used commercially at a large scale, they infiltrate the environment at a rapid pace. However, the impact of large quantities of AgNPs on aquatic ecosystems is still largely unknown. In aquatic ecosystems, the phytoplanktons have a vital ecological function and, therefore, the potential impact of AgNPs on ...

Toxic effects of pristine and aged polystyrene and their leachate on marine microalgae Skeletonema costatum.

Science of the Total Environment, 2022
The acute toxic effects of pristine and aged polystyrene (P-PS and A-PS) and their leaching solutions (L-PS) on microalgae Skeletonema costatum were investigated by measuring algal density and growth inhibition rate (IR), chlorophyll concentration and ...

Microplastics decrease the toxicity of sulfamethoxazole to marine algae (Skeletonema costatum) at the cellular and molecular levels.

Science of the Total Environment, 2022
Microplastics (MPs) and sulfamethoxazole (SMX) are ubiquitous in various aquatic environments, but little is known about their joint toxicity mechanism on marine organisms.

Transcriptomic analysis provides insights into the algicidal mechanism of cocamidopropyl betaine against the red tide microalgae Skeletonema costatum.

Marine Environmental Research, 2022
This study investigated the effect of the surfactant cocamidopropyl betaine (CAB) on the growth of red tide microalgae Skeletonema costatum. It was found that CAB caused cell lysis in a time- and dose-dependent manner and significantly inhibited the ...

The allelopathy and underlying mechanism of Skeletonema costatum on Karenia mikimotoi integrating transcriptomics profiling.

Aquatic Toxicology, 2021
The roles of allelopathy for succession of marine phytoplankton communities remain controversial, especially for the development of blooms. Physiological parameters measurement (Fv/Fm value, MDA content, SOD activity, Na+/K+, Ca2+/ Mg2+-ATPase activity ...

Development of environmentally friendly biological algicide and biochemical analysis of inhibitory effect of diatom Skeletonema costatum

Chinese Chemical Letters, 2021
Skeletonema costatum is a diatom widely distributed in red tide microalgae blooms and as one of the main algae causing harmful algal blooms, because of their rapid reproduction and production of toxic and harmful substances, often play a negative role in

UBIQUITIN INSKELETONEMA COSTATUM

Diatom Research, 1995
Western blotting experiments performed with an anti-ubiquitin antibody showed that Skeletonema costatum cells contained free ubiquitin and high molecular weight ubiquitin conjugates. An estimate of free ubiquitin and ubiquitin conjugates by a solid phase immunoassay (Haas & Bright 1985) provided values of 0.31 ± 0.04 pmol/107 cells for free ubiquitin ...

Growth inhibition of the microalgae Skeletonema costatum under copper nanoparticles with microplastic exposure.

Marine Environmental Research, 2020
In order to investigate the combined toxicities of copper nanoparticles (nano-Cu) with microplastic on microalgae Skeletonema costatum, growth inhibition tests were carried out. The toxic effects of copper nanoparticles and microplastic on the microalgae

Production of Octadienal in the Marine Diatom Skeletonema costatum

Organic Letters, 2003
[reaction: see text] Marine diatoms produce alpha,beta,gamma,delta-unsaturated aldehydes that have detrimental effects on the reproduction of their natural predators. The production of these defensive metabolites is suggested to involve enzymatic oxidation of polyunsaturated fatty acids. In this paper, feeding experiments with labeled precursor provide
