Quantifying Viral Lysis in Microalgae Using Cell-Free rRNA. [PDF]

open access: yesMicrobiologyopen
Cell‐free ribosomal RNA (rRNA) dissolved in seawater provides a quantitative proxy for viral lysis in microeukaryotic phytoplankton. Incubation experiments with two distinct host–virus systems revealed marked increases in cell‐free rRNA production per cell, a proxy for lytic mortality, reaching up to 46‐ and 302‐fold relative to noninfected controls ...

The Chaetocerosphere: Chaetoceros Species and Associated Prokaryotes in a Coastal Area. [PDF]

open access: yesEnviron Microbiol Rep
Chaetoceros species maintain recurrent distinct prokaryotic assemblages in their phycosphere. Alphaproteobacteria, Bacteroidetes and Archaea Thermoplasmata and Marine Group II are the most represented in the phycosphere. Bipartite networks highlight strong links between the diatom and specific prokaryotic taxa, especially the chain‐forming species ...

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

open access: yesMarine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

The Potential of Chaetoceros muelleri in Bioremediation of Antibiotics: Performance and Optimization [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2021
Antibiotics are frequently applied to treat bacterial infections in humans and animals. However, most consumed antibiotics are excreted into wastewater as metabolites or in their original form. Therefore, removal of antibiotics from aquatic environments is of high research interest.

Ultrastructure of setae of a planktonic diatom, Chaetoceros coarctatus

open access: yesScientific Reports, 2022
AbstractSilica frustules of most planktonic diatoms have many shallow holes in which the length (L) is smaller than the width (W). The present study focuses on a silica ultrastructure of setae of a planktonic diatom having deep (L/W > 1) holes. Here, we characterized microscopically patterned nanoholes on the silica walls of thick, robust, and ...

Removal of Pharmaceutical Micropollutants with Integrated Biochar and Marine Microalgae

open access: yesMicroorganisms, 2020
Using microalgae to remove pharmaceuticals and personal care products (PPCPs) micropollutants (MPs) have attracted considerable interest. However, high concentrations of persistent PPCPs can reduce the performance of microalgae in remediating PPCPs ...

Insight into the morphology and genetic diversity of the Chaetoceros tenuissimus (Bacillariophyta) species complex

open access: yes, 2022
Among the marine planktonic diatoms, Chaetoceros is among the most species-rich genera, and many Chaetoceros species are considered important primary producers. However, little is known about the ecology and distribution of the few small solitary species
