Assessment of cyanoprokaryote blooms and of cyanotoxins in Bulgaria in a 15-years period (2000-2015)
Advances in Oceanography and Limnology, 2017 The scientific and public awareness of hazardous photosynthetic prokaryotes (cyanobacteria/cyanoprokaryotes) and especially the contamination of drinking-water reservoirs with cyanotoxins is world-wide increasing.

Bacterial Production of Saxitoxin
Agricultural and Biological Chemistry, 1988 A bacterium was isolated from the homogenate of Protogonyaulax tamarensis cells cultured in T1 medium containing antibiotics. The culture broth after centrifugation, to remove the cells, and the bacterial cells contained a toxin that could kill mice with signs similar to those of poisoning by paralytic shellfish toxins or tetrodotoxin. The toxin in the

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]
, 2015 Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...

Development and field assessment of a quantitative PCR for the detection and enumeration of the noxious bloom-former Anabaena planktonica [PDF]
, 2007 Anabaena planktonica is a harmful, bloom-forming freshwater cyanobacterium, which has arrived recently in New Zealand. In the short time since its incursion (

Visible Fluorescence Chemosensor for Saxitoxin [PDF]
The Journal of Organic Chemistry, 2007 Absorption spectra of a number of shellfish extracts have been obtained and reveal prominent absorptions in all samples at 210 and 260 nm and at 325 nm in some of them. These absorptions preclude the use of chromophores with similar absorptions in testing of shellfish samples for paralytic shellfish toxins.
