Insects such as black soldier fly larvae (BSFL) are gaining interest among researchers and the aquafeed industry due to fluctuating price supply of fish meal (FM). This study evaluated growth performance, feed stability, blood biochemistry, liver gut morphology Betta splendens using BSFL an alternative FM. Five formulated diets were prepared: 0% BSFL, 6.5% 13% 19.5% 24.5% BSFL. The expansion ra...

pythium irregulare oomycetes adapts with environmental changes including crude oil concentration by changing the composition of lipids in the cytoplasmic membrane and providing the required characteristics for adaptation in improper and stressful environmental situations. it was found that cultivation of pythium irregulare lx oomycetes in the nutrient media with different concentrations of crud...

Aerial parts of 38 taxa, distributed in 21 genera and all three subfamilies of the Bromeliaceae have been examined for the presence of betaines. Glycinebetaine and trigonelline were isolated from all the plants studied, although the yields of both compounds were low. For glycinebetaine, values (based upon dry weight) varied from 0.0004% for Pitcairnia corallina to 0.087% for Tillandsia usneoide...

A combination of solid-phase-extraction (SPE) and reversed-phase preparative high-performance liquid chromatography (prep-HPLC) of the methanolic extract of the aerial parts of Artemisia splendens (common name: “Asia Minor Wormwood”), an endemic Iranian species, afforded Zand E-melilotosides (1 and 2), Zand E-4-methoxy-melilotosides (3 and 4), and a new dimer, bis-ortho-Z-melilotoside (5, named...

Corn yield reduction following a cereal rye cover crop has been attributed to, among other factors, allelochemicals released from decomposing residue. The allelopathic effect of 6-methoxy-2-benzoxazolinone (MBOA) was evaluated on corn seedling growth, mycelial growth seven pathogenic species Pythium, and root rot seedlings caused by Pythium spp. at 13, 16, 22 to 23°C (room temperature) using pl...

Ikan cupang (Betta splendens) jantan memiliki harga jual yang tinggi daripada ikan betina karena mempunyai warna lebih menarik, tubuh ramping, sirip panjang, dan agresif. Penelitian ini bertujuan untuk mengetahui pengaruh perendaman artemia (Artemia salina) menggunakan air kelapa (Cocos nucifera) terhadap keberhasilan maskulinisasi konsentrasi terbaik sebagai media pengarahan kelamin pada splen...
