Diatoms are photosynthetic secondary endosymbionts found throughout marine and freshwater environments, and are believed to be responsible for around one-fifth of the primary productivity on Earth. The genome sequence of the marine centric diatom Thalassiosira pseudonana was recently reported, revealing a wealth of information about diatom biology. Here we(More)
The extraction of proteins and DNA from seaweed tissue is difficult due to the presence of cell wall anionic polysaccharides that, after cell disruption, remain in the extraction medium as hydrocolloidal compounds. These compounds increase medium viscosity, thus limiting access to and, consequently, quantification of the soluble macromolecules such as(More)
Genus Penicillium represents an important fungal group regarding to its mycotoxin production. Secondary metabolomes of eight marine-derived strains belonging to subgenera Furcatum and Penicillium were investigated using dereplication by liquid chromatography (LC)-Diode Array Detector (DAD)-mass spectrometry (MS)/MS. Each strain was grown on six different(More)
Gold nanoparticles (AuNPs) have important technological applications resulting in an increased potential for release to the environment, and a greater possibility of toxicological effects. The marine bivalve Scrobicularia plana was exposed to AuNPs of size 5, 15 and 40 nm during a 16 d laboratory exposure at 100 μg Au L(-1). After exposure to AuNPs forming(More)
We report a DNA isolation protocol for red seaweeds. Recovering DNA of high quality and quantity is a prerequisite for ensuring suitable applications, such as polymerase chain reaction (PCR), restriction fragment length polymorphism (RFLP) analysis, and sequencing. Isolation of DNA from seaweeds has proven difficult because of coprecipitation of(More)
