The taxonomy and toxicity of a single‐filament isolate from a filamentous cyanobacterial bloom in Lake Hakanoa (New Zealand) were examined by microscopy and liquid chromatography–mass spectrometry. Based on a morphological examination of environmental and cultured material, strain CAWBG02 was identified as Raphidiopsis mediterranea Skuja; however, subsequent phylogenetic analysis of the 16S rRNA gene sequence demonstrated that CAWBG02 was most likely to be a single culture of Aphanizomenon… 
First report of saxitoxins and anatoxin-a production by cyanobacteria from Lithuanian lakes
TLDR
This study describes the first report on saxitoxins (STXs) and anatoxin-a (ANTX-a) production by cyanobacteria in Lithuanian lakes and confirms that A. gracile formed a genetically homogenous group.
Phylogeography of Cylindrospermopsin and Paralytic Shellfish Toxin-Producing Nostocales Cyanobacteria from Mediterranean Europe (Spain)
TLDR
It is confirmed that the nostocalean genus Aphanizomenon is a major source of CYN and PSP toxins in Europe and demonstrates the presence of the sxtA gene in CYN-producing AphanIZomenon ovalisporum.
Molecular characterization of bloom- forming Aphanizomenon strains isolated from Vela Lake (Western Central Portugal)
TLDR
Molecular phylogenetic results corroborated the morphological identification and fingerprinting showed a persistent occurrence of Aph.
UNRAVELING MOLECULAR DIVERSITY AND PHYLOGENY OF APHANIZOMENON (NOSTOCALES, CYANOBACTERIA) STRAINS ISOLATED FROM CHINA 1
TLDR
It is suggested that the taxonomic revision of Aphanizomenon and Anabaena genera is required to be performed by employing multilocus sequence analysis and polyphasic studies.
Isolation and preliminary characterization of cyanobacteria strains from freshwaters of Greece
TLDR
This study presents, for the first time, a cyanobacteria culture collection from Greece, thus providing missing study material for the understanding of bloom formation and cyanotoxin production in the Mediterranean and for the polyphasic characterization of important components of the phytoplankton.

IDENTIFICATION OF CYLINDROSPERMOPSIN IN APHANIZOMENON OVALISPORUM (CYANOPHYCEAE) ISOLATED FROM LAKE KINNERET, ISRAEL 1
TLDR
The active compound was found to be the sulfate‐guanidinium zwitterion, cylindrospermopsin, previously isolated from the cyanobacterium CylINDrospermopsis raciborskii (Woloszynska) and recently also reported in Umezakia natans.
Molecular Characterization of the Toxic Cyanobacterium Cylindrospermopsis raciborskii and Design of a Species-Specific PCR
TLDR
Genetic profiles of C. raciborskii were examined in 19 cultured isolates originating from geographically diverse regions of Australia and represented by two distinct morphotypes, and randomly amplified polymorphic DNA and short tandemly repeated repetitive sequence profiles revealed a greater level of genetic heterogeneity among isolates than did rpoC1 gene analysis.
Strain characterization and classification of oxyphotobacteria in clone cultures on the basis of 16S rRNA sequences from the variable regions V6, V7, and V8
TLDR
An accurate method for characterization, classification and identification of oxyphotobacterial clone cultures has been developed using the DNA sequence polymorphism in the 16S rRNA regions V6 to V8 for individual strain characterization and identification.
Pharmacology of anatoxin-a, produced by the freshwater cyanophyte Anabaena flos-aquae NRC-44-1.
Anatoxin‐a toxin in the cyanobacterium Planktothrix rubescens from a fishing pond in northern Italy
TLDR
A heavy algal bloom occurring in a fishing pond in northern Italy full of Salmo trutta was examined for algae taxonomy and toxic production, and it was revealed to be toxic in mouse and Vibrio fischeri bioassays.
Phylogenetic and morphological evaluation of the genera Anabaena, Aphanizomenon, Trichormus and Nostoc (Nostocales, Cyanobacteria).
TLDR
The present study confirmed that Anabaena and Aphanizomenon strains were not monophyletic, as previously demonstrated and showed that the current classification of these anabaenoid genera needs to be revised.
Multiplex PCR assay for Cylindrospermopsis raciborskii and cylindrospermopsin‐producing cyanobacteria
TLDR
A multiplex polymerase chain reaction (PCR) test was developed that simultaneously identified polyketide synthase (pks) and peptide synthetase (ps) determinants associated with cylindrospermopsin production and distinguished C. raciborskii from other cylindromopsin‐producing cyanobacteria of the species Anabaena bergii and Aphanizomenon ovalisporum.
Taxonomic re-evaluation of Aphanizomenon flos-aquae NH-5 based on morphology and 16S rRNA gene sequences
TLDR
The Aphanizomenon strains investigated in this study are classified to four morphological groups as described by the classical taxonomy of Komárek & Kovácik (1989) and supported from the phylogenetic results of 16S rRNA gene sequences.
Identification of genes implicated in toxin production in the cyanobacterium Cylindrospermopsis raciborskii
TLDR
Examination of the strain‐specific distribution of the PKS and PS genes in C. raciborskii isolates demonstrated a direct link between the presence of these two genes and the ability to produce cylindrospermopsin, suggesting a likely role for these determinants in secondary metabolite and toxin production by C. raceskii.
