On the Chemistry, Toxicology and Genetics of the Cyanobacterial Toxins, Microcystin, Nodularin, Saxitoxin and Cylindrospermopsin

open access: yesMarine Drugs, 2010
The cyanobacteria or “blue-green algae”, as they are commonly termed, comprise a diverse group of oxygenic photosynthetic bacteria that inhabit a wide range of aquatic and terrestrial environments, and display incredible morphological diversity.

Macro‐ and micronutrient effects on phytoplankton in Green Bay, Lake Michigan, and the western basin of Lake Erie

open access: yesJournal of Phycology, Volume 60, Issue 6, Page 1514-1527, December 2024.
Abstract Efforts to reduce the frequency, extent, and toxicity of harmful algal blooms (HABs) require knowledge about drivers of algal growth, toxin production, and shifts in phytoplankton community composition to cyanobacterial dominance. Although labile nitrogen (N) and phosphorus (P) fuel primary production, micronutrients also play roles as the ...

Single domain antibody: Development and application in biotechnology and biopharma

open access: yesImmunological Reviews, Volume 328, Issue 1, Page 98-112, November 2024.
Summary Heavy‐chain antibodies (HCAbs) are a unique type of antibodies devoid of light chains, and comprised of two heavy chains‐only that recognize their cognate antigen by virtue of a single variable domain also referred to as VHH, single domain antibody (sdAb), or nanobody (Nb).

Rapid clean-up and effective sample preparation procedure for unambiguous determination of the cyclic peptides microcystin and nodularin [PDF]

open access: yes, 1999
A new sample preparation strategy has been established to improve the identification and determination of nodularin and microcystins. The sample preparation consisted of enrichment of the analytes by solid phase extraction with C18 cartridges followed by

Variable Cyanobacterial Toxin and Metabolite  Profiles across Six Eutrophic Lakes of Differing  Physiochemical Characteristics

open access: yesToxins, 2017
Future sustainability of freshwater resources is seriously threatened due to the presence of harmful cyanobacterial blooms, and yet, the number, extent, and distribution of most cyanobacterial toxins—including “emerging” toxins and other bioactive ...

Underway measurement of cyanobacterial microcystins using a surface plasmon resonance sensor on an autonomous underwater vehicle

open access: yesLimnology and Oceanography: Methods, Volume 22, Issue 9, Page 681-699, September 2024.
Abstract Freshwater cyanobacterial harmful algal blooms (CHABs) are a well‐known global public health threat. Monitoring and early detection of CHAB toxins are currently accomplished using labor‐intensive sampling techniques and subsequent shore‐based analyses, with results typically reported 24–48 h after sample collection.

Photocatalytic degradation of eleven microcystin analogues and nodularin by TiO2 coated glass microspheres [PDF]

open access: yes, 2015
Microcystins and nodularin are toxic cyanobacterial secondary metabolites produced by cyanobacteria that pose a threat to human health in drinking water. Conventional water treatment methods often fail to remove these toxins. Advanced oxidation processes

The chemical and microbiological safety of emerging alternative protein sources and derived analogues: A review

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 4, July 2024.
Abstract Climate change and changing consumer demand are the main factors driving the protein transition. This shift toward more sustainable protein sources as alternatives to animal proteins is also reflected in the rapid upscaling of meat and dairy food analogues.

Determination of six microcystins and nodularin in surface and drinking waters by on-line solid phase extraction–ultra high pressure liquid chromatography tandem mass spectrometry [PDF]

open access: yes, 2012
Microcystins and nodularin are cyclic peptides hepatotoxins produced by cyanobacterial genera (blue-green algae). Toxic cyanobacterial blooms are a worldwide problem, as reported in several countries, like China, Australia, or the United States ...
