Problem statement: Although the diversity of marine Actinobacteria have been studied and biotechnologically exploited throughout the world, the studies on marine actinobacteria in Indian peninsula are largely unexplored. Of 9 maritime states in India, only 4 states have been extensively studied for the diversity of actinobacteria. Further, the studies on bioactive actinomycetes from saline soil...

Os inseticidas são agrotóxicos utilizados para controlar insetos prejudiciais às plantações agrícolas. Entretanto, o uso exacerbado de pode resultar em efeitos tóxicos à saúde humana e inúmeros impactos socioambientais. Diferentes ensaios toxicidade podem ser analisar efeito tóxico determinadas substâncias. Dentre eles, bioensaio com Artemia salina é considerado um teste rápido, confiável custo...

in the present work, the bioassay screening of the essential oil and various extracts of two plants including fruits of heracleum persicum desf. and rhizomes of zingiber officinale rosc. have been studied with brine shrimp test. there is only one report about cytotoxicity of h. sphondylium in literature and so h. persicum has been used as second selection. at first essentials oil and various ex...

Artemia franciscana C. Drewes (updated, 2002) http://www.zool.iastate.edu/~c_drewes/ http://www.zool.iastate.edu/~c_drewes/Artemph.jpg Taxonomy Phylum: Arthropoda Subphylum): Crustacea Class: Branchiopoda (includes fairy shrimp, brine shrimp, daphnia, clam shrimp, tadpole shrimp) Order: Anostraca (brine shrimp and fairy shrimp) Genus and species: Artemia franciscana (= the North American versio...

Betulinic, ursolic and oleanolic acids isolated from the aerial parts of Eriope blanchetii (Lamiaceae) were subjected to different esterification reactions, yielding 12 C-3 position ester derivatives. All compounds were identified using spectroscopic techniques, such as IR, 1H-NMR and MS. The derivatives were further investigated for their antioxidant level, Artemia salina lethality and antimic...

This study was designed to examine the nutritional composition, antioxidant activity and medium lethal concentration (LC50 value) of Tamarindus indica L. pulp and seed extracts in vitro. The extraction was set at 40◦C, 60◦C and 100◦C for 12 hours, 6 hours and 15 minutes respectively to determine the optimum extraction parameter whereas the anti-oxidant activity of the extracts was measured usin...

60S ribosomes from encysted gastrulae of the brine shrimp Artemia salina contain two acidic proteins, which are homologous to the Escherichia coli proteins L7 and L12. The proteins were purified and characterized with respect to molecular weight, amino-acid composition, peptide maps, and their functional requirement in the elongation factor dependent binding of aminoacyl transfer RNA to the rib...
