Estimation of Cochlodinium polykrikoides growth potential using a dialysis membrane.
We developed a test to measure the growth potential of C. polykrikoides using a dialysis membrane and artificial seawater. Nitrite nitrogen and inorganic phosphorus in the medium were almost completely removed when the medium was dialyzed against artificial seawater for five or more 6-hour cycles using a dialysis membrane (Spectrum's Spectra/Por 7 Membrane) with a molecular-weight cut-off of 50...
متن کاملEvaluation of the sub-lethal toxicity of Cu, Pb, bisphenol A and polychlorinated biphenyl to the marine dinoflagellate Cochlodinium polykrikoides
Algae are sensitive to a wide range of pollutants, and are effective bioindicators in ecotoxicity assessments. Here, we evaluated the sub-lethal sensitivity of the marine dinoflagellate Cochlodinium polykrikoides upon exposure to copper (Cu), lead (Pb), bisphenol A (BPA), and Aroclor 1016 (polychlorinated biphenyl, PCB). Toxic effects were assessed by observations of the reduction in cell count...
متن کاملEffect of Higher Plant Essential Oils for the Control of Red Tide Algae Cochlodinium polykrikoides under Laboratory Conditions
Antialgal activity of Zataria multiflora, Satureja khuzistanica and S. rechingeri were evaluated. These plant species are easily cultivable and their algicidal activity make them suitable candidate as biocontrol. This study aimed to identify effective algicidal compounds, practically new algicidal agents from essential oils of plants that could inhibit the growth of red tide microalgae. Prepare...
متن کاملAlgicidal Activity of Bacillamide Alkaloids and Their Analogues against Marine and Freshwater Harmful Algae
Harmful algal blooms have become a great challenge to global aquatic ecosystems over the past decades. Given their low toxicity, high selectivity, and environment-friendly properties, the use of natural products and their analogues as algicides has proven to be particularly efficient. In the present study, algicidal activity of naturally occurring bacillamides A-C, alkaloid (1), and neobacillam...
متن کاملAntibacterial Activity of Marine Sponge Extracts against Fish Pathogenic Bacteria
Secondary metabolites of the marine sponges Acanthella elongata, Axinella donnani, Callyspongia diffusa, Callyspongia subarmigera, and Echinodictyum gorgonoides were collected from fishing nets and their in vitro antibacterial properties against eight virulent marine fish pathogens were studied at incubation temperatures of 20°C and 30°C. Crude methanol extracts of the tested sponges showed spe...
