Twenty-three isolates of fungi, representing 13 thermophilic and thermotolerant species, were bioassayed for toxigenicity to brine shrimp, chicken embryos, and rats. Thirteen isolates representing nine genera were highly toxic to at least two of the three systems. Seven additional isolates of five genera were slightly toxic.

 Recently, the nutritional requirements of marine finfish larvae have received considerable attention, and studies have shown that docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and arachidonic acid (ARA) affects the growth and survival of marine finfish larvae. This study investigated the effects of different Artemia enrichments containing variable amounts of DHA and EPA on the gro...

the probiotic effects of two gram positive bacteria, bacillus subtilis and bacillus licheniformis, were examined on growth performance, body composition and survival rate of artemia urmiana. three diets containing 102 (t1), 104 (t2), 106 (t3) cfu of probiotics g feed-1 and a control diet (c) without probiotic were used through a completely randomized design (each with three replicates). the use...

This study determined the effect of prey DHA on larval gilthead sea bream (GSB; Sparus aurata ) photoreceptor abundance, rhodopsin expression, and growth performance. It was carried out in a twenty-eight 400 l conical tank system that stocked with 100 viable GSB eggs/l/tank. allowed testing 4 levels rotifer DHA; 0.99 (Low; L), 1.9 (Intermediate low; I-L), 3.2 high; I-H) 12.1(High; H) mg DHA/g D...

Essential oils of Duguetia lanceolata barks, obtained at 2 (T2) and 4 h (T4), were identified by gas chromatography and gas chromatography/mass spectrometry. β-elemene (12.7 and 14.9%), caryophyllene oxide (12.4 and 10.7%) and β-selinene (8.4 and 10.4%) were the most abundant components in T2 and T4, respectively. The essential oils inhibited the growth of Staphylococcus aureus, Streptococcus p...
