Departamento de Farmacia, Universidad de Cartagena. The dinoflagellate Alexandrium minutum was toxic for A.

The quality and sensitivity of the model organisms used in the different bioassays was evaluated by the use of reference substances. Alexandrium minutum ; Prymnesium parvum ; Paracentrotus lividus ; Artemia franciscana ; Corophium multisetosum ; toxicity bioassays.
Using multiple ecosystem components, in assessing ecological status in Spanish Basque Country Atlantic marine waters.
Marine standard water was used as a control and I. Organophosphates Search for additional papers on arteemia topic. The inverted light-microscope technique based upon fixed samples used in this monitoring programme for phytoplankton identification and counting does not usually allow species or even genus-level identification, of small naked flagellates such us Prymnesium spp.
The toxicity was investigated using the two Gram positive bacteria Bacillus subtilis and Staphylococcus aureus, bioensay two Gram negative bacteria Escherichia coli and Pseudomonas aeruginosa. For Artemia salina toxicity assay, the aryemia most active were all from the 2nd and 3rd collections.
In continuation of investigation for environmentally benign protocol for new solvents termed deep eutectic solvents DESsit is herein reported results concerning the toxicity and cytotoxicity of choline chloride ChCl based DESs with four hydrogen bond donors including glycerine, ethylene glycol, triethylene glycol and urea.
Wound- activated chemical defense in unicellular planktonic algae. As a result, it cannot be concluded that the higher sensitivity of A. After incubation, one replicate per treatment was used to measure tocicidad, salinity and temperature in order to ensure normal optimal conditions. The cytotoxicity of tested DESs was much higher than that of their individual components, indicating their toxicological behavior was different.
However, a dose-dependent toxic effect of several marine microalgae on sea urchin cell division has been recorded in several studies Paul and Fenical Paul V.
Considering the filtrate of P. Snakebites and ethnobotany in the northwest region of Colombia. Differences were considered as significant when p was lower than 0. Skip to search form Skip to main content. We then made a qualitative chemical identification of hydrolysable tannins and condensed tannins.
By contrast, the culture and filtrate bkoensayo P. These crustaceans are characterized by their adaptability to a wide range of salinity and temperature conditions: This finding contrasts with those of other authors who have routinely used adult zooplankton organisms Euterpina acutifrons and Acartia grani to evaluate the toxicity of A. From This Paper Figures, tables, and topics from this paper. Taxonomic identification was performed through cellular scale characterization, using transmission electron microscopy Seoane et al.

Nova Science Publishers Inc. On the other hand, A.
Seasonal variability in gonad development in the sea urchin Paracentrotus lividus on the Basque coast southeastern Bay of Biscay. The abiotic parameters in all microalgae culture flasks oxygen, salinity and temperature are reported in Table 2. Toxicity tests were performed with both cultures A. Initial test 0; ; ; ; ; ; Definitive test 0; ; ; ; ; C. Variety of PSP toxin profiles in various culture strains of Alexandrium tamarense and change of toxin profile in natural A.
Crescentia cujete, totumo, Aedes aegypti, Artemia salina, Allium cepa. Bioensayos con Paracentrotus lividus y Corphium sp. Its life cycle begins with the hatching of dormant cysts that, once rehydrated in salt water, start the development as nauplii larvae, which are the material for the bioassays. A set of ecotoxicological tests was carried out to investigate the effects of A.
According to the aforementioned authors, excretion of toxic metabolites might be a general mechanism among toxic haptophytes when exposed to stress events, e.
As conclusion, the biornsayo observed for HME and DF is biodnsayo due to the presence of 1 and 2 in aetemia constitution. Adtemia that time, amphipods were considered dead when no movements were registered within 60 seconds. Duroia macrophylla Rubiaceae is endemic from the Amazon Rainforest. The active extracts of D. Thermal and pH stabilities ranged from 0oC to about 50oC and biioensayo 6.
