Abstract
Abstract Euglena sanguinea is known to produce the alkaloid toxin euglenophycin and is known to cause fish kills and inhibit mammalian tissue and microalgal culture growth. An analysis of over 30 species of euglenoids for accumulation of euglenophycin identified six additional species producing the toxin; and six of the seven E. sanguinea strains produced the toxin. A phylogenetic assessment of these species confirmed most taxa were in the Euglenaceae, whereas synthesis capability apparently has been lost in the Phacus, Eutreptiella, and Discoplastis branches.

Aquatic microbes produce diverse secondary metabolites with interesting biological activities. Cytotoxic metabolites have the potential to become lead compounds or drugs for cancer treatment. Many cytotoxic compounds, however, show undesirable toxicity at higher concentrations. Such undesirable activity may be reduced or eliminated by using lower doses of the cytotoxic compound in combination with another compound that modulates its activity. Here, we have examined the cytotoxicity of four micro...

Abstract In this study, we investigated the relationships between microcystin (MCs) concentrations and the biovolumes of Planktothrix rubescens (B Pr ) in 2 natural lakes (Pusiano and Garda) and 2 artificially dammed reservoirs (Occhito and Ledro) in Italy. In all the considered water bodies, P. rubescens was the dominant cyanobacterium. All the lakes were characterized by significant relationships between MCs and B Pr , with limited variability in the MC quota (the content of MCs per unit of bi...

Patchiness plays a fundamental role in phytoplankton ecology by dictating the rate at which individual cells encounter each other and their predators. The distribution of motile phytoplankton species is often considerably more patchy than that of non-motile species at submetre length scales, yet the mechanism generating this patchiness has remained unknown. Here we show that strong patchiness at small scales occurs when motile phytoplankton are exposed to turbulent flow. We demonstrate experimen...

Euglenophycin is a recently discovered toxin produced by at least one species of euglenoid algae. The toxin has been responsible for several fish mortality events. To facilitate the identification and monitoring of euglenophycin in freshwater ponds, we have developed a specific mass spectrometric method for the identification and quantitation of euglenophycin. The post-extraction stability of the toxin was assessed under various conditions. Euglenophycin was most stable at room temperature. At 8...

Abstract Recurrent blooms of the marine flagellate genus Pseudochattonella have caused several fish kills in Northern Europe and Japan during the last two decades. Six different bioassays using fish cells, fish and brine shrimp nauplii were assessed as test systems for investigating ichthyotoxic mechanisms of Pseudochattonella . Metabolic activity in embryo cells from chinook salmon (CHSE-214) was inhibited in 2 strains, increased in another strain but was unaffected in a further 2 strains when ...

Abstract Currently cyanoprokaryotic algae, diatoms, haptophytes, dinoflagellates, euglenoids, and rhaphidophytes are known to produce algal toxins. A previous study by the authors reported euglenoid algae producing toxin(s) in aquaculture ponds, with confirmation based on positive fish bioassays following exposure to the isolated clonal algal cultures. Toxicity was observed in euglenoid culture isolates obtained from the pond as well as a clonal, culture collection taxon. Here we provide conclus...

Background Sundarbans is the largest chunk of mangrove forest and only tiger mangrove land in the world. Compared to the rich species diversity and uniqueness, very few studies have so far been conducted here, mainly due to its inaccessibility. This study explores water quality, density of biomass, species diversity, phytoplankton abundance and bacterial population of a tidal creek in Sunderban estuary during the post and pre monsoon period of 2008-09.

Karlodinium veneficum (D. Ballant.) J. Larsen strains, 16 from the U.S. Atlantic eastern seaboard and two from New Zealand (CAWD66 and CAWD83), were used to characterize toxin profiles during batch culture. All 18 strains were determined as the same species based on ITS sequence analyses, a positive signal in a chloroplast real-time PCR assay and pigment composition. Five karlotoxin 1 (KmTx 1) containing strains were analyzed from the Chesapeake Bay, and 10 karlotoxin 2 (KmTx 2) strains were ana...

Abstract Microalgae-derived functional materials, such as food supplements, drugs, and biofuels have gained a great deal of attention in recent times. Among the several microalgae investigated for biomaterials production, Euglena spp. are particularly attractive due to their easiness to grow in cultures and the ability to produce numerous bioactive compounds through extremely complex metabolic pathways. The genus Euglena comprises more than 300 species of unicellular, predominantly freshwater fl...

Euglena sanguinea Ehrenberg is the only known species of euglenids which forms toxic blooms causing tangible losses to fish farms. Euglena sanguinea produces euglenophycin, a toxin similar in structure to solenopsin, an alkaloid found in fire ant venom. It was proved that euglenophycin exhibits not only ichthyotoxic but also herbicidal and anticancer activity. Recently, a specific mass spectrometric method of identification and quantitation of euglenophycin was developed to facilitate monitoring...

Abstract Hydrological regimes are key in shaping the structure of phytoplankton communities in estuaries. Because anthropogenic disturbances often alter the quantity and quality of riverine inputs, this research focused on investigating phytoplankton dynamics in the St. Lucia Estuary, since being reconnected to the Mfolozi River. Due to the closed mouth state of the estuary, the input from the river resulted in oligohaline (≥5) conditions and the characteristic reverse salinity gradient to persi...

Abstract The phototrophic euglenophyte Eutreptiella eupharyngea often causes blooms in the coastal waters of many countries, but its mode of nutrition has not been assessed. This species has previously been considered as exclusively auxotrophic. To explore whether E. eupharyngea is a mixotrophic species, the protoplasm of E. eupharyngea cells were examined using light, epifluorescence, and transmission electron microscopy after eubacteria, the cyanobacterium Synechococcus sp., and diverse algal ...
