Oxidative stress responses in two marine diatoms during acute n-butyl acrylate exposure and the toxicological evaluation with the IBRv2 index

Ecotoxicology and Environmental Safety, 2022
n-Butyl acrylate (nBA), a typical hazardous and noxious substance (HNS), is the largest-volume acrylate ester used to produce various types of polymers. With the increasing volume of nBA subject to maritime transportation, its accidental leakage poses a ...

Vibrio Community Structure Shapes the Diversity of Carbenicillin‐Hydrolysing Class A β‐Lactamase Circulating in European Coastal Environments

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Vibrio communities shape carbenicillinase diversity in European coasts. Sediments serve as reservoirs of antibiotic‐resistant Vibrio alginolyticus, which can move into the water column and accumulate in bivalves. This spreads β‐lactamase resistance and raises human exposure risks to antibiotic‐resistant pathogenic Vibrio, especially as higher seawater ...

Sexual Reproduction of Centric Diatom Skeletonema costatum

NIPPON SUISAN GAKKAISHI, 1967
The sexual reproduction and auxospore formation of Centrales had been misinterpreted for a long time. It was believed until recently that auxospore formation had no connection with sexual reproduction. More recently, however, STOSCH2) demonstrated oogamy clearly in Melosira varians for the first time, and since then STOSCH4-8) and GEITLER9, 10) studied

Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus

New Phytologist, Volume 251, Issue 3, Page 1161-1171, August 2026.
Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...

Algicidal characteristics of novel algicidal compounds, cyclic lipopeptide surfactins from Bacillus tequilensis strain D8, in eliminating Heterosigma akashiwo blooms

Frontiers in Microbiology, 2022
Heterosigma akashiwo blooms have caused severe damage to marine ecosystems, the aquaculture industry and human health worldwide. In this study, Bacillus tequilensis D8 isolated from an H. akashiwo bloom area was found to exert high algicidal activity via

Full‐year in situ imaging reveals fine‐scale habitat differences among salp and doliolid life stages

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Doliolids and salps are pelagic tunicates that reproduce both asexually and sexually during their life history, occasionally forming massive blooms (> 1000 ind. m−3) that can clear large volumes of water daily. Although blooms of doliolids and salps are often associated with pulses of primary productivity, little is understood about their life

The metabolism of wax esters and other lipids by the marine copepod, Calanus helgolandicus

Journal of Lipid Research, 1970
The polyunsaturated wax esters which occur in an oil droplet in Calanus helgolandicus apparently serve as a short term reserve metabolic fuel. The lipids of the copepods were labeled by feeding them 14C-labeled diatoms, Skeletonema costatum, after which ...
