Special Issue Information

Dear Colleagues,

Mycotoxins are fungal secondary metabolites and are contaminant of several feed and food chains. They have deleterious effects on humans and animals. Mycotoxin contamination can take place at all stages of the supply chain (from the field to the processing of raw materials, including storage). As these molecules are very resistant and persist throughout food processing, it is necessary to limit their presence as early as possible. On one hand, actions can be taken during cultivation as well as during raw materials storage. One the other hand, mycotoxin concentration can be modified during food processing. For example, it is described that some food/feed processes such as microbial fermentation can reduce the concentration of certain mycotoxins in the corresponding finished products.

The focus of this Special Issue of Toxins is on the most recent advances related to the reduction of mycotoxin concentration in food and feed agrofood chains. Manuscripts that provide data on mechanisms aiming to reduce fungal growth and degrade or eliminate contaminating mycotoxins are invited. Works on new developments in food control leading to the reduction of mycotoxin concentration are also welcome. Particular attention will be devoted to works highlighting the modes of action allowing the reduction of mycotoxin concentration in the final products.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a double-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxins is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In malt production, steeping and germination steps offer favorable environmental conditions for fungal proliferation when barley is already contaminated by Fusarium species, T-2 toxin producers. However, the use of G. candidum as a biocontrol agent can prevent this proliferation. Indeed, in previous work, a correlation between phenyllactic acid (PLA) production by G. candidum and the reduction in Fusarium sporotrichioides and F. langsethiae growth and T-2 toxin concentration was demonstrated. In the present study, to improve the efficiency of G. candidum, the effects of the inoculum concentration and the inoculation method of G. candidum on PLA and T-2 toxin concentrations were evaluated. First, co-culture experiments with Fusarium species and G. candidum were conducted in a liquid synthetic medium. The results showed that inoculation of G. candidum in the freeze-dried form at 0.4 g/L allowed the production of PLA from the second day of incubation associated with a reduction in T-2 toxin concentration of 82% and 69% produced by F. sporotrichioides and F. langsethiae, respectively. Moreover, the activated form of G. candidum at 0.4 g/L enhanced PLA concentration leading to better T-2 toxin reduction. Second, experiments were conducted on artificially infected barley kernels with both Fusarium species under conditions mimicking the malting step. As for co-culture experiments, the use of the activated form of G. candidum was established as the best condition for T-2 toxin concentration reduction for a 3 day malting period. Full article
