Marine cyanobacteria as sources of new biotechnological applications

Frontiers in Marine Science, 2014
Cyanobacteria are very diverse organisms in terms of morphology, habitat and ecology (Brito et al., 2012) and are well known for the diversity of secondary metabolites that they produce either when living isolated or in symbiosis (Alex et al.2013 ...

Kaempferol Protects Intestinal Health in Chinese Forest Musk Deer Possibly by Regulating Intestinal Microbiota and Inhibiting the NF‐κB/NLRP3 Signaling Pathway

Integrative Zoology, EarlyView.
Kaempferol modulates the tryptophan metabolism pathway by increasing the abundances of Christensenellaceae R7 group, Bacteroides, and Blautia and reducing that of Rikenellaceae RC9 gut group, thereby significantly increasing the levels of ILA and IAA. This process inhibits the activation of NF‐κB/NLRP3 signaling pathway, reduces pro‐inflammatory factor

Immune Evasion of Helicobacter pylori and Extra‐Gastric Cancer Risk

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Helicobacter pylori (H. pylori) is a group 1 gastric carcinogen that plays a significant role in extra‐gastric digestive system cancers. H. pylori disrupts host cell homeostasis through expression of virulence factors leading to immune evasion as well as persistent gastric mucosal colonization. H. pylori infection has been shown to play a role

Application of hydrogen peroxide to the control of eutrophic lake systems in laboratory assays [PDF]

, 2014
We exposed water samples from a recreational lake dominated by the cyanobacterium Planktothrix agardhii to different concentrations of hydrogen peroxide (H2O2). An addition of 0.33 mg·L−1 of H2O2 was the lowest effective dose for the decay of chlorophyll-

Toxin Producing Cyanobacteria in Labugama, Kalatuwawa Drinking Water Reservoirs

Proceedings of International Forestry and Environment Symposium, 2015
Cyanobacteria are photosynthetic bacteria found naturally in lakes, streams, ponds, and reservoirs. Microcystis aeruginosa, Anabaena sp., Nostoc sp., Oscillatoria sp. are some harmful cyanobacteria that produce cyanotoxins. Microcystin-LR (MC-LR) is the dominant type of cyanotoxin produced by these cyanobacteria.

Klebsiella sp. strain B7 enhances alkaline tolerance by secreting pyruvic acid to accelerate L‐malic acid accumulation in soybean

Journal of Integrative Plant Biology, EarlyView.
Klebsiella sp. strain B7 acts as a positive regulator in alkaline stress responses in soybean. By activating pyruvic acid metabolism and L‐malic acid biosynthesis pathways, B7 significantly increases alkaline tolerance and yield in soybean. ABSTRACT Alkaline stress is a major constraint on crop growth and development and negatively impacts soybean ...

Cyanobacterial Toxins as Allelochemicals with Potential Applications as Algaecides, Herbicides and Insecticides

Marine Drugs, 2008
Cyanobacteria (“blue-green algae”) from marine and freshwater habitats are known to produce a diverse array of toxic or otherwise bioactive metabolites. However, the functional role of the vast majority of these compounds, particularly in terms

Biosynthesis and Molecular Genetics of Polyketides in Marine Dinoflagellates

Marine Drugs, 2010
Marine dinoflagellates are the single most important group of algae that produce toxins, which have a global impact on human activities. The toxins are chemically diverse, and include macrolides, cyclic polyethers, spirolides and purine alkaloids ...
