Rapid urbanization and economic development in coastal regions have significantly increased nutrient pollution remarkably changed the phytoplankton community developed some species into bloom, resulting large losses serious threats to public health. Therefore, it is indispensable reveal shift abundance, phytoplankton’s environmental drivers. However, previous studies could not present details o...

The Bacanga River Estuary is socioeconomically important due to artisanal fishing and aquaculture. It blocked by a dam under human pressure along its drainage basin, intensifying the eutrophication process. This study reports on occurrence of phytoplankton blooms trophic state (TSI TRIX) at six sampling sites during annual cycle. estuary was divided into downstream upstream regions. Higher sali...

Nitrate uptake has been studied in nitrogen-deficient cells of the marine diatom Skektowema costatum. When these cells are incubated in the presence of nitrate, this ion is quickly taken up from the medium, and nitrite is excreted by the cells. Nitrite is excreted following classical saturation kineffcs, its rate being independent of nitrate concentration in the incubation medium for nitrate co...

The phytoplankton in coastal regions are responding to constant environmental changes, thus the use of proxies derived from situ frequent time-series observations and validated traditional microscopic or pigment methods can be a solution for detecting rapid responses community dynamics succession. In this study, we combined high-frequency (every 30 min May September 2017) optical hydrographic d...

Bivalves accumulate toxins produced by microalgae, thus becoming harmful for humans. However, little information is available about their toxicity to the bivalve itself. In present work, physiological stress and damage after ingestion of toxic dinoflagellate species (Gymnodinium catenatum) a diatom (Skeletonema marinoi, which non-toxic humans but may be grazers) in oyster Magallana angulata are...

Arenibacter algicola strain TG409 was isolated from Skeletonema costatum and exhibits the ability to utilize polycyclic aromatic hydrocarbons as sole sources of carbon and energy. Here, we present the genome sequence of this strain, which is 5,550,230 bp with 4,722 genes and an average G+C content of 39.7%.

We report here the genome sequence of Loktanella vestfoldensis strain SMR4r, isolated from the marine diatom Skeletonema marinoi strain RO5AC. Its 3,987,360-bp genome consists of a circular chromosome and two circular plasmids, one of which appears to be shared with an S. marinoi-associated Roseovarius species.
