this experiment was conducted to evaluate the efficacy of different levels of echinacea (echinacea purpurea) methanol extract on the growth performances (final weight (fw), daily growth ratio (dgr), feed conversion rate (fcr), voluntary feed intake (vfi) and protein efficiency ratio (per) and some of hematological parameters (hemoglobin (hb), hematocrit (hct), red blood cell (rbc) and white blo...

Among of the actual challenges for sustainable aquaculture development are to lower trophic level cultured species, and increase use by-products from primary sector. The golden mullet (Liza aurata) is a marine low consumer present in Mediterranean Canary Islands, where there was significant consumption past. On other hand, Aloe vera plant, which production Islands highly world representative, c...

This work reports the production of a novel alkaline protease from the fungus Aspergillus niger. The protease was purified from the culture supernatant to homogeneity using ammonium sulfate precipitation, Sephadex G-150 gel filtration and DEAE-sepharose ion exchange chromatography with a 13.9-fold increase in specific activity. The molecular weight of the enzyme was estimated to be 32 kDa on SD...
