Evaluation of the nutritional quality of Chaetoceros muelleri Schütt (Chaetocerotales: Chaetocerotaceae) and Isochrysis sp. (Isochrysidales: isochrysidaceae) grown outdoors for the larval development of Litopenaeus vannamei (Boone, 1931) (Decapoda: Penaeidae) [PDF]

Archives of Biological Sciences, 2012
The biomass, proximal composition and fatty acid profile of Isochrysis sp., Chaetoceros muelleri and their mixture, grown under greenhouse conditions, were evaluated.

Differential association of key bacterial groups with diatoms and Phaeocystis spp. during spring blooms in the Southern Ocean. [PDF]

Microbiologyopen
We used rbcL and 16S rRNA gene sequencing to characterize phytoplankton and bacterial communities in size‐fractionated samples. Our correlation analysis between the most abundant phytoplankton and bacterial operational taxonomic units revealed distinct bacterial groups associated with the dimethylsulfoniopropionate (DMSP) producer Phaeocystis ...

Morphology and ecology of the diatom Chaetoceros vixvisibilis (Chaetocerotales, Bacillariophyceae) from the Adriatic Sea [PDF]

Journal of Plankton Research, 2010
The chain-forming diatom Chaetoceros vixvisibilis is one of the most abundant and frequent diatoms in the northeastern Adriatic Sea. This species had not been previously studied by electron microscopy. Its general morphology is similar to those species allocated in the subgenus Hyalochaete: cells and chains (straight, of variable length, usually 4-8 ...

Microalgae Classification Using Improved Metaheuristic Algorithm

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
Microalgae are present at all levels of nutrients and food networks, so in aquatic environments they are an important part of the food chain of aquatic organisms, which also play an important role as biological purifiers of water resources and regulation.

Observations onChaetoceros salsugineus(Chaetocerotales, Bacillariophyceae): first record of this bloom-forming diatom in a European estuary [PDF]

European Journal of Phycology, 2002
Examination of material obtained from the Urdaibai estuary (North Spain) during a 2 year phytoplankton sampling programme revealed a rare species of the genus Chaetoceros, C. salsugineus Takano. The morphology of this small (4·0×5·5 µm) member of the subgenus Hyalochaetae has been described using both light and electron microscopy.

Springtime upwelling conditions influence microbial communities and dissolved thiamin compounds in the California Current Ecosystem

Limnology and Oceanography, Volume 70, Issue 5, Page 1386-1403, May 2025.
Abstract Understanding dissolved concentrations of the essential coenzyme thiamin (vitamin B1) can provide insights into the biological controls on highly productive upwelling systems such as the California Current Ecosystem. To connect thiamin availability with microbial communities in the California Current Ecosystem, we measured concentrations of ...

Differences in Sinking Processes and Biological Pump Contribution Among Phytoplankton Groups in the Mesopelagic Layer

Global Biogeochemical Cycles, Volume 39, Issue 4, April 2025.
Abstract The differing contributions of phytoplankton groups to biological pump have been insufficiently explored. We evaluated the sinking of phytoplankton in the mesopelagic layer using 16S rRNA gene amplicon sequencing. Sinking particles were collected from June to August 2022 in the Sea of Japan using sediment traps moored at depths of 387 and 890 ...
