Purification and characterization of phenoloxidase from brine shrimp Artemia sinica.
Phenoloxidase from Artemia sinica (AsPO) was purified by Superdex 200 gel-filtration and Q Sepharose fast flow ion-exchange chromatography, and its properties were characterized biochemically and enzymatically by using L-dihydroxyphenylalanine (L-DOPA) as the specific substrate. Results showed that AsPO was isolated as a monomeric protein of 125.5 kDa in molecular mass. The optimal pH value and...
متن کاملA gynandromorph of the brine shrimp, Artemia salina.
S EXUAL mosaics have been reported in three genera of Crustacea. A bilateral mosaic of Carcinus was found to have a testis on one side and a mixed gonad on the other (VEILLET 1945). Gynandromorphs with a testis and ovary have been reported in Homarus (see review by CHACE and MOORE 1959) and in the cladoceran, Simocephalus (BANTA, WOOD, BROWN and INGLE 1939). No intersex or mosaic of Artemia has...
متن کاملToxicity of benthic dinoflagellates on grazing, behavior and survival of the brine shrimp Artemia salina
Harmful algae may differently affect their primary grazers, causing sub-lethal effects and/or leading to their death. The present study aim to compare the effects of three toxic benthic dinoflagellates on clearance and grazing rates, behavioral changes, and survival of Artemia salina. Feeding assays consisted in 1-h incubations of brine shrimps with the toxic Prorocentrum lima, Gambierdiscus ex...
متن کاملN-Acetyl-ß-D-hexosaminidases of the Brine Shrimp Artemia: Partial Purification and Characterization
N-Acetyl-ß-D-hexosaminidases (EC 3.2.1.52) from Artemia nauplii were isolated and char acterized. Three different enzymes I, II, and II2 were separated according to their behaviour on anion exchange chromatography and gel filtration columns. Their apparent molecular masses were 83,000 ± 7000, 110,000 ± 10,000 and 56,000 ± 5000 Da with corresponding S-values o f 8.6, 11.9 and 7.9. All three enz...
متن کاملThe Detection and Quantification of Cyanobacterial Toxins in Water Using the Brine Shrimp (Artemia salina) Assay
The cyanobacteria (blue-green algae) are an ancient and ubiquitous group of prokaryotes that form dense growths or blooms in eutrophic water bodies. The blooms are of interest to aquaculturists and water management authorities due to their production of taste and odour compounds and/or potent natural toxins. The study focused on method development for toxin extraction and detection in cyanobact...
