Seaweed liquid fertilizers (SLFs) contain macronutrients, micronutrients and trace nutrients essential for microalgal growth. The study aims to evaluate the efficiency of SLFs on biomass production, biochemical physiological processes; was carried out at different SLF concentrations selected seaweeds i.e. Kappaphycus alvarezii, Gelidiella acerosa Turbinaria ornata. comparative analysis growth p...

Microalgae are sunlight-driven green cell factories for the production of potential bioactive products and biofuels. Nannochloropsis represents a genus of marine microalgae with high photosynthetic efficiency and can convert carbon dioxide to storage lipids mainly in the form of triacylglycerols and to the ω-3 long-chain polyunsaturated fatty acid eicosapentaenoic acid (EPA). Recently, Nannochl...

Three different microalgae species, Desmodesmus sp., Nannochloropsis oculata and Halamphora coffeaeformis were grown under controlled conditions. The resulting dry biomass was characterized by TG-DTA (thermogravimetry-differential thermal analysis) extracted with three solvents having polarities. extracts gross mass yields varied from 2% using n-hexane to 23% (or 74% when subtracting the volati...

Green lacewings (Neuroptera: Chrysopidae) are voracious predators of aphids and other small, soft-bodied insects and mites. Earlier, we identified (1R,2S,5R,8R)-iridodial from wild males of the goldeneyed lacewing, Chrysopa oculata Say, which is released from thousands of microscopic dermal glands on the abdominal sterna. Iridodial-baited traps attract C. oculata and other Chrysopa spp. males i...
