| systematics of scorpaeniformes species in the mediterranean sea inferred from mitochondrial 16s rdna sequence and morphological data. | genetic and morphological divergence and phylogenetic relationships of scorpaeniformes fish including two genera and six species, helicolenus dactylopterus, scorpaena maderensis, scorpaena porcus, scorpaena elongata, scorpaena scrofa, scorpaena notata, living in the mediterranean sea, were investigated with morphological and mitochondrial 16s rdna sequence data. the mean nucleotide diversity was found to be 0.0792. average sequence divergence between species of sebastidae and scorpaenidae was 8. ... | 2009 | 19777968 |
| purification and biochemical characterization of a neutral serine protease from trichoderma harzianum. use in antibacterial peptide production from a fish by-product hydrolysate. | this study reports the purification and biochemical characterization of an extracellular neutral protease from the fungus trichoderma harzianum. the protease (th-protease) was purified from the culture supernatant to homogeneity by a three-step procedure with 14.2% recovery and 9.06-fold increase in specific activity. the purified enzyme appeared as a single protein band after sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) with a molecular mass of about 20 kda. the optimum ... | 2016 | 27987188 |
| fish assemblages of mediterranean marine caves. | fish assemblages associated with 14 marine caves and adjacent external rocky reefs were investigated at four marine protected areas (mpas) along the coasts of italy. within the caves sampling was carried out in different sub-habitats: walls, ceilings, bottoms and ends of caves. on the whole, 38 species were recorded inside the 14 caves investigated. eighteen species were exclusively found inside the caves: they were mainly represented by speleophilic (i.e. species preferentially or exclusively i ... | 2015 | 25875504 |
| a new species of microcotyle (monogenea: microcotylidae) from scorpaena notata (teleostei: scorpaenidae) in the mediterranean sea. | we collected specimens of microcotyle spp. from two species of scorpaeniform fishes off algeria, namely scorpaena notata and helicolenus dactylopterus. the identification of both fishes was confirmed by molecular barcoding of the coi gene. sequences of coi gene were also obtained for both parasite species. the species from s. notata is described as microcotyle algeriensis n. sp., on the basis of morphological differences from other species (number of clamps, number of spines in genital atrium, n ... | 2017 | 27840197 |
