Special Issue Information

Dear Colleagues,

This Special Issue focused on the study of the effect of major mycotoxins on the quality attributes of crops, the possible methods of preventing mycotoxin infection, and various methods that could be applied to degrade the mycotoxins. Mycotoxins are responsible for financial loss to the agricultural industry, product quality losses, and harmful effects on human and livestock health. Therefore, it is of great importance to develop and optimize methods for mycotoxin prevention, or its degradation on the crops. Currently, there is no adequate method in the industry for mycotoxin degradation on the crops. There are different methods for mycotoxin degradation such as thermal treatment, chemical treatment, biological/enzymatic, irradiation treatments, light treatment, ultrasound treatment, ozone, and atmospheric cold plasma treatment. Each of these methods has limitations and there is a gap in knowing the degradation mechanism of some of these methods which needs further study. Therefore, this Special Issue highlights the studies focusing on the impact of mycotoxins on the crops and various methods for its prevention or degradation. It is exciting to build this Special Issue with your participation and compile the works in this area to show our progress in overcoming mycotoxin contamination.

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.

Penicillium expansum is one the major postharvest pathogens of pome fruit during postharvest handling and storage. This fungus also produces patulin, which is a highly toxic mycotoxin that can contaminate infected fruits and their derived products and whose levels are regulated in many countries. In this study, we investigated the biocontrol potential of non-mycotoxigenic strains of Penicillium expansum against a mycotoxigenic strain. We analyzed the competitive behavior of two knockout mutants that were unable to produce patulin. The first mutant (∆patK) involved the deletion of the patK gene, which is the initial gene in patulin biosynthesis. The second mutant (∆veA) involved the deletion of veA, which is a global regulator of primary and secondary metabolism. At the phenotypic level, the ∆patK mutant exhibited similar phenotypic characteristics to the wild-type strain. In contrast, the ∆veA mutant displayed altered growth characteristics compared with the wild type, including reduced conidiation and abnormal conidiophores. Neither mutant produced patulin under the tested conditions. Under various stress conditions, the ∆veA mutants exhibited reduced growth and conidiation when exposed to stressors, including cell membrane stress, oxidative stress, osmotic stress, and different pH values. However, no significant changes were observed in the ∆patK mutant. In competitive growth experiments, the presence of non-mycotoxigenic strains reduced the population of the wild-type strain during in vitro growth. Furthermore, the addition of either of the non-mycotoxigenic strains resulted in a significant decrease in patulin levels. Overall, our results suggest the potential use of non-mycotoxigenic mutants, particularly ∆patK mutants, as biocontrol agents to reduce patulin contamination in food and feed. Full article
