Microcystins, BMAA and BMAA isomers in 100-year-old Antarctic cyanobacterial mats collected during Captain R.F. Scott’s Discovery Expedition

From the abstract of a new paper by Jungblut et. al (2018) published in European Journal of Phycology :

Microcystins (MCN), β-N-methylamino-L-alanine (BMAA) and anatoxin-a were investigated in Antarctic cyanobacterial mats collected from Ross Island and the McMurdo Ice Shelf, East Antarctica during Captain Scott’s ‘Discovery’ National Antarctic Expedition (1901–1904). Ultra-performance liquid chromatography-photodiode array detection (UPLC-PDA) and tandem mass spectrometry (MS/MS) analysis were used to quantify the cyanotoxins in seven cyanobacterial mat samples. MCNs were identified in six of the mat samples at concentrations from 0.5 to 16.1 µg g–1 dry weight. BMAA was found in one sample (528 ng g–1 dry weight, total BMAA), as well as two BMAA isomers, 2,4-diaminobutyric acid (DAB) and N-(2-aminoethyl) glycine (AEG) in six samples up to 6.56 and 6.79 μg g–1 dry weight, respectively. No anatoxin-a was detected. The findings confirm that MCNs, BMAA and BMAA isomers are preserved under dry herbarium conditions. The ‘Discovery’ cyanobacterial mat samples represent the oldest polar cyanobacterial samples found to contain cyanotoxins to date and provide new baseline data for cyanotoxins in Antarctic freshwater cyanobacterial mats from prior to human activity in Antarctica, the development of the ozone hole and current levels of climatic change.

ICHA2018 Session: Mitigation of HABs and water treatment technologies

A Session on Mitigation of HABs and water treatment technologies is chaired by   Petra VISSER (University of Amsterdam, The Netherlands) / Triantafyllos KALOUDIS (EYDAP SA, Greece) – Session co-chairs*: Jean-François HUMBERT / Anthony MASSE,  within ICHA2018  in Nantes (21 to 26 October 2018).

Session description:

This session will focus (i) on the different approaches allowing to prevent and control blooms of toxic algae and cyanobacteria in natural and artificial environments, (ii) on the technologies allowing to remove cyanobacteria, cyanotoxins and odor-causing compounds in drinking water treatment and (iii) technologies treating ships’ ballast waters. From a more global point of view, issues on the sustainable managment of natural ecosystems can be approached during this session and joint communications between environmental and social sciences will be encouraged.

The deadline for abstract submission is now extended to 1 May 2018 !!!

See the list of session topics of ICHA2018.

ICHA2018 Session: Optical sensors and drone systems for the monitoring of harmful blooms

A Session on Optical sensors and drone systems for the monitoring of harmful blooms is chaired by  Jean-François HUMBERT (INRA, Institut d’Ecologie et des Sciences de l’Environnement de Paris, UPMC), co-chair: Kamel Soudani  within ICHA2018  in Nantes (21 to 26 October 2018).

Session description:

This session will concern the use of new sensors and of drone systems for the monitoring of harmful blooms in marine and freshwater ecosystems. One part of the session will permit to present the results obtained in the framework of a French research program (OSS-Cyano) on the development of a low cost aerial sensor and of a drone system able to carry the sensor and different tools for water sampling or for performing underwater measurements. This session will be open to other talks on the new technologies allowing to perform continuous monitoring of algal blooms and/or to assess the spatial distribution of these blooms.

The deadline for abstract submission is 15 April 2018 !!!

Session description:

This session invites presentations on any major HAB events since the last conference, as well as analysis of long-time series, i.e. multi-annual datasets.

The deadline for abstract submission is 15 April 2018 !!!

Session description: Any information, study or survey related to a full risk assessment of human health effects associated with marine or freshwater toxins or on one of the key steps, such as hazard characterization (dose-response relationship), consumption survey, exposure assessment.

The deadline for abstract submission is 15 April 2018 !!!

ICHA2018 Session : Toxin Analysis – Novel detection methods

A Session on Toxin Analysis – Novel detection methods is chaired by Ana GAGO (Univ. Vigo, Spain) with co-chairs Ronel BIRE / Zouher AMZIL, within ICHA2018  in Nantes (21 to 26 October 2018).

Determination of toxins has to address many challenges related to the diversity of compounds, the complexity of the matrices, the availability of standards and reference materials etc. A wide array of techniques is available among which functional assays, biochemical assays and chemical methods but may not address all the issues related to the analysis of the toxins. New detection methods taking on board the latest technical advances are necessary as they offer novel approaches.

The deadline for abstract submission is 15 April 2018 !!!

Sponges-Cyanobacteria associations: Global diversity overview and new data from the Eastern Mediterranean

A new paper has been published by Konstantinou et al. (2018) from Cyanolab AUTH, in PlosOne. The authors summarize the global diversity of sponge species hosting cyanobacteria, as well as the diversity of cyanobacterial symbionts and provide a detailed list, along with new data from the Aegean Sea, a previously unexplored eastern ecoregion. The evaluation of the literature along with the new data from the Aegean Sea raised the number of sponge species known for hosting cyanobacteria to 320 and showed that the cyanobacterial diversity reported from sponges is yet underestimated. Highlight of the research is the isolation of nine cyanobacteria strains (only 19 cyanobacteria strains have been isolated to date from sponges). The nine isolated cyanobacteria were found to form novel clades within Synechococcus, Leptolyngbyaceae, Pseudanabaenaceae, and Schizotrichaceae. This is the first report of a Schizotrichaceae cyanobacterium associated with sponges. The results of this research propose the occurrence of new sponge-cyanobacteria associations and new cyanobacteria taxa.
