Synthesis of Natural and Unnatural Cyclooligomeric Depsipeptides Enabled by Flow Chemistry. [PDF]

, 2016
Flow chemistry has been successfully integrated into the synthesis of a series of cyclooligomeric depsipeptides of three different ring sizes including the natural products beauvericin (1 a), bassianolide (2 b) and enniatin C (1 b).

Polycistronic gene expression in Aspergillus niger

Microbial Cell Factories, 2017
Background Genome mining approaches predict dozens of biosynthetic gene clusters in each of the filamentous fungal genomes sequenced so far. However, the majority of these gene clusters still remain cryptic because they are not expressed in their natural

Co-Occurrence and Levels of Mycotoxins in Fish Feeds in Kenya

Toxins, 2020
This study determined the presence, levels and co-occurrence of mycotoxins in fish feeds in Kenya. Seventy-eight fish feeds and ingredients were sampled from fish farms and fish feed manufacturing plants and analysed for 40 mycotoxins using high ...

Plant‐Based Analogs: Potential Chemical Risks & Mitigation Strategies

Journal of Food Science, Volume 90, Issue 9, September 2025.
ABSTRACT Meat, dairy, and egg analogs are products designed to mimic the structural and sensorial properties of their animal counterparts. These analogs have been developed to address diverse nutritional requirements, dietary preferences, and ethical considerations, resulting in a substantial net growth in market share in recent years.

Expression and purification of an adenylation domain from a eukaryotic nonribosomal peptide synthetase: Using structural genomics tools for a challenging target [PDF]

, 2010
Nonribosomal peptide synthetases (NRPSs) are large multimodular and multidomain enzymes that are involved in synthesising an array of molecules that are important in human and animal health.

Mycotoxin Incidence in Some Fish Products: QuEChERS Methodology and Liquid Chromatography Linear Ion Trap Tandem Mass Spectrometry Approach

Molecules, 2019
The inclusion of vegetal raw materials in feed for fish farming has increased the risk of mycotoxin occurrence in feed, as well as in edible tissues from fish fed with contaminated feed, due to the carry-over to muscle portions.

The mycotoxin Beauvericin is an uncompetitive inhibitor of Cathepsin B

Protein Science, Volume 34, Issue 6, June 2025.
Abstract Beauvericin (BEA), a cyclic depsipeptide, is a mycotoxin of the enniatin family and the secondary metabolite of various toxigenic fungi. Multiple biological functions of BEA have been well investigated, such as anti‐cancer, anti‐inflammatory, anti‐microbial, and immune‐activating functions. In a recent study, we showed that BEA can target Toll‐

Geographical Distribution of Fusarium Species Involved in Fusarium Head Blight and Fusarium Crown Rot of Wheat in Tunisia and Their Mycotoxin Accumulation

Plant Pathology, Volume 74, Issue 5, Page 1290-1301, June 2025.
This study highlights a great diversity of Fusarium species on durum wheat in Tunisia, higher in crowns than in kernels, with F. culmorum as the dominant species and five species detected for the first time. ABSTRACT Fusarium crown rot (FCR) and Fusarium head blight (FHB) are among the most destructive diseases of wheat worldwide.

Beauvericin and enniatin B mycotoxins alter aquatic ecosystems: Effects on green algae

Environmental Toxicology and Pharmacology
Myxotoxins can contaminate algal-based products and arrive to the food chain to consumers producing chronic toxicity effects. Here, we studied phytotoxicity of mycotoxins, beauvericin (BEA) and ennaitin B (ENN B) in four phytoplankton strains: Acutodesmus sp., Chlamydomonas reinhardtii, Haematococcus pluvialis, and Monoraphidium griffithii, which are ...

Evaluation of the Efficacy of Mycotoxin Modifiers and Mycotoxin Binders by Using an In Vitro Rumen Model as a First Screening Tool

Toxins, 2020
Ruminal microbiota of cattle are not able to detoxify all mycotoxins. In addition, detoxification can be hampered by adverse ruminal conditions (e.g., low ruminal pH).
