Bacteria from several groups of marine organisms were isolated and, using direct antibiograms, identified those that produce antibacterial substances, using a human pathogenic strain of Staphylococcus aureus ATCC6538 as revealing microorganism. Bacteria which produce substances that inhibited S. aureus growth were identified through morphological,(More)
The antibacterial activity of marine fungi extracts was evaluated by a test of efficiency. The fungi were previously inoculated in Malt Agar (EMA) extract with 50% of seawater and growth for 60 days. Triplicate antibiograms were carried out with the extracts. An ANOVA I with a posteriori Duncan test were applied to the diameters of inhibition zones. The(More)
We evaluated native marine microalgae isolated from NortheasternVenezuela, as food for Litopenaeus vannamei larvae,compared to six microalgae commonly used in aquaculture. We evaluated themicroalgal ingestability calculating the biomass consumed by larvae, later weevaluated three monoalgal diets on protozoea stages of L.vannamei over 72 hr based on the(More)
In 1987 to 1989 the composition was studied of the nitrogen compounds (nitrogen and free amino acids) in the fruit juice of Persian lime during its commercial harvesting period. Adult Persian lime trees grafted on Citrus macrophylla and C. volkameriana were used, planted on a groundwater-affected red ferrilytic soil in the La Habana Province. Determination(More)
We quantified the abundance of juvenile Pinna carnea at Turpialito, Golfo de Cariaco, Venezuela, using collectors suspended at 8 m depth for 16 months and then evaluated their subsequent growth in suspended enclosures over 14 months in relation to concurrent measures of temperature and planktontonic food availability. All body components showed a rapid(More)
