This article presents materials on the results of an experiment enrichment Artemia salina with unicellular alga Haematococcus pluvialis to increase its nutritional value. For fry marine fish, such as mullet and kalkana, freshwater clary catfish, carp trout, supply fatty acids energy value is still insufficient. Therefore, it necessary enrich brine shrimp additional nutrients The use a component...

The aroma and taste of eight different phototrophic microalgae species were investigated compared with five seaweeds to evaluate their potential as flavor ingredients in plant-based seafood alternatives. To assess performance, commercial flavoring products used a reference during the sensory evaluation chemical odor-active taste-active profiles those algae. Stronger odor observed Rhodomonas sal...

This study evaluated the antimicrobial, antioxidant and toxicity activity of essential oils (EOs) Hymenaea courbaril L. var. bark Syzygium cumini (L.) Skeels leaves. The EOs were extracted by hydrodistillation chemically characterized gas chromatography coupled to mass spectrometry (GC/MS). ABTS DPPH assay used evaluate activity. For assay, lethality was against Artemia salina Leach. antimicrob...

Avermectin inhibits Mucor miehei and Artemia salina chitin synthesis and to a degree DNA synthesis in the former. The antibiotic interferes with chitin turnover in brine shrimp and inhibits Streptomyces antibioticus chitinase activity in vitro. In light of the proposed mode of action of avermectin and the anomolies in the literature, it is proposed that avermectin can kill susceptible organisms...

Hexane, ethanol and aqueous extracts and fractions from leaves of Pouteria torta (Mart.) Radlk (Sapotaceae), a perennial tree, widespread in the Brazilian Cerrado, were tested for cytotoxicity with the Artemia salina toxicity model. Only the aqueous crude extract and the MeCN: CHCl3 fraction of the ethanol extract presented toxicity (0.28 mg/mL and 0.27mg/mL, respectively). Lupeol acetate was i...

Cinnamomum species have long been used as spices. The preliminary bioactive constituent’s identification and brine shrimp lethality activities of ethanolic extracts of seven Cinnamomum species viz., C. travancoricum, C. walaiwarense, C. wightii, C. verum, C. sulphuratum, C. riparium, and C. perrottetii were evaluated in this study. The results of cytotoxic activity of the bark extracts of seven...

Antibodies against nitrate reductase from Monoraphidium braunii have been used to determine the antigenic relationships of nitrate reductases from different green algae. Nitrate reductases from Chlamydomonas reinhardii, Chlorella fusca, Dunaliella salina, and Scenedesmus obliquus, were inhibited by, and cross-reacted with, antibodies raised against the enzyme from Monoraphidium braunii.These an...

Sterols, triterpenes, volatiles, polar and other constituents in aerial parts of Carthamus lanatus were analyzed by gas chromatography-mass spectrometry. Over 90 compounds were identified most of them new for the species. Sitosterol and stigmasterol were the most abundant of 10 sterols identified in the sterol fraction. Taraxasterol, alpha- and beta-amyrine prevailed in the triterpene fraction....
