Animal venoms are rich in bioactive molecules with promising biotechnological potential. They comprise both protein and non-protein toxins. Among the protein toxins are enzymes, such as phospholipases A2, proteases and L-amino acid oxidases (LAAOs)....

Toxic cyanobacteria, including Microcystis, produce harmful toxins that affect aquatic ecosystems and human health. Biotreatment using macrophytes shows promise in mitigating these blooms. This study investigates the bioaccumulation dynamics and bioc...

Toxins are naturally poisonous small compounds, peptides and proteins that are produced in all three kingdoms of life. Venoms are animal toxins and can contain even hundreds of different compounds. Numerous approaches have been used to detect toxins,...

The genus Oxyuranus, which includes some of the most venomous snakes in the world, presents a complex venom composition with potent neurotoxic and procoagulant effects. This study provides a comparative proteomic analysis of the venom of Oxyuranus mi...

Grapes are frequently contaminated by Aspergillus section Nigri fungi and ochratoxin A (OTA), with A. niger also capable of producing substantial fumonisin B2 (FB2) levels. Emerging evidence suggests that aflatoxigenic fungi may eventually replace oc...

Spiders of the Sicarius genera (Araneae: Sicariidae) are commonly known as six-eyed sand spiders. Of the species described in Latin America, the species S. thomisoides has previously been shown to possess venom with a toxic potential comparable to th...

Clostridium botulinum strains produce seven antigenically distinct botulinum neurotoxins (BoNTs), referred to as serotypes A–G, and a hybrid toxin called F/A [...]

The secondary contamination of nodularin disinfection by-products (NOD-DBPs) is a problem worthy of attention. In this study, prototypical NOD-R-DBPs were prepared, and their toxicity was assessed using conventional protein phosphatase (PPs) inhibiti...

Cereal contamination by mycotoxins represents a major food safety concern. This study aimed to assess the co-occurrence of 15 mycotoxins in 50 couscous samples marketed in Algeria using HPLC/FLD and LC-MS/MS techniques. The samples included various c...

Aflatoxin B1 (AFB1), the most potent and widespread mycotoxin produced by Aspergillus flavus and Aspergillus parasiticus, poses a significant global threat to food safety and human health, with chronic exposure strongly linked to hepatocellular carci...
