BACKGROUND Artemia (Crustacea, Anostraca), also known as brine shrimp, are typical inhabitants of extreme environments. These hypersaline environments vary considerably in their physicochemical composition, and even their climatic conditions and elevation. Several thalassohaline (marine) environments along the Colombian Caribbean coast were surveyed in order to contribute to the knowledge of br...

Secondary metabolites from Bupleurum salicifolium were tested against viruses, Gram-positive and Gram-negative bacteria, the yeast Candida albicans, the nematodes Globodera pallida and G. rostochiensis, the insect Spodoptera littoralis and the crustacean Artemia salina. These compounds were also tested against tumoral and non-tumoral cell lines. The polyacetylene 8S-heptadeca-2(Z)-9(Z)-diene-4,...

Dinesh Kumar Culture and biofuel producing efficacy of marine microalgae Dunaliella salina and Nannochloropsis sp. J. Algal Biomass Utln. 2012, 3 (4): 38–4 Abstract Biodiesel from oil crops, waste cooking oil and animal fat cannot realistically satisfy even a small fraction of the existing...

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...

In the present work we identified and quantified the effect of hydrodynamic stress on two different microalgae strains, Dunaliella tertiolecta and D. salina, cultivated in bench-scale bubble columns. The cell death rate constant increased with increasing gas-entrance velocity at the sparger. Dunaliella salina was slightly more sensitive than D. tertiolecta. The critical gas-entrance velocities ...

The recent discovery of the production of anti-proliferative aldehydes in a variety of microalgal species has lead to considerable investigation into the effects of these toxins on aquatic invertebrates. Studies have, however, rarely considered the impact pollutants may have on grazer responses to algal toxins. In this study, the acute toxicities of five aldehydes to the rotifer Brachionus plic...

The development of drugs for photodynamic therapy (PDT) is an important area of research due to their growing use in medical applications. Therefore, it is important to develop new bioassay methods for PDT photosensitizers that are inexpensive, easy to handle and highly sensitive to environmental conditions. Xanthene dyes (fluorescein, rose bengal B, erythrosine B and eosin Y) with LED light so...

Dunaliella salina is a unicellular green microalga that is considered as one of the best commercial sources of carotenoids. Growth and pigment production of D. salina (isolated from Sambhar Salt Lake, Rajasthan) was studied by using various inorganic media differing in chemical compositions viz. Artificial Sea Water media, De Walne’s media, Johnson’s media, AS-100 and Modified Bold’s Basal medi...

The extracts and sesquiterpene lactones of S.argentinum were assayed to determine their biological activity on Artemia salina. The most active compound was costunolide (1) with LD50= 62 ppm. Introduction Our previous phytochemical study of Stachychephalum argentinum (Asteraceae), revelead the presence of several skeletal types sesquiterpene lactones [1]. In order to explore new natural bioactiv...
