Dans Estuaries and Coasts (32(6) NOV 2009)

The enzyme-labeled fluorescence (ELF-97A (R)) substrate produces an insoluble, fluorescent yellow-green product at the site of alkaline-phosphatase (AP) activity. Fifteen coastal phytoplankton species were tested to determine if AP activity coul[...]

Silicon Deficiency Induces Alkaline Phosphatase Enzyme Activity in Cultures of Four Marine Diatoms

Soledad Fuentes, Auteur ; Gary H. Wikfors, Auteur ; Shannon Meseck, Auteur

Dans Estuaries and Coasts (37(2) MAR 2014)

Alkaline phosphatase (AP) was detected using ELF-97A (R) in silicon-starved Pseudo-nitzschia multiseries cells; thus, we tested two, alternative hypotheses: Pseudo-nitzschia multiseries has a high phosphate demand, showing signs of phosphate def[...]
