Special Issue Information

Dear Colleagues,

Although great achievements have been made in controlling crop diseases caused by mycotoxigenic fungi, the fact is that mycotoxin contamination still cannot be avoided under the current agricultural practices. Moreover, the genetic alterations in some mycotoxigenic fungal populations have escalated the levels of mycotoxin contamination, and climate changes have already shown in certain geographic areas to possibly increase both the prevalence and severity of major mycotoxins. Globally, more than six hundred million metric tons of grains alone may be contaminated with various mycotoxins annually based on the FAO estimate of 25% mycotoxin contamination and the data of grain production worldwide. The contaminated grains and other food commodities present an ongoing safety burden in food supply chains, intensify food insecurity, add more challenges in environment protection, and cause substantial economic losses directly or indirectly. Therefore, postharvest strategies to mitigate mycotoxin contamination are truly essential and extremely critical. One such strategy is detoxification, which has shown very promising results in many studies and is attracting more and more researchers and industrial developers.

This Special Issue aims to provide an effective platform for 1) reporting discoveries of innovative mycotoxin detoxifications, including scientific concepts, novel technologies, and new organisms and agents, etc.; 2) illustrating understandings of detoxification mechanisms; and 3) demonstrating application possibilities and technologies. Both research (in particular) and review articles are welcome. We expect that the Special Issue will turn out to be a comprehensive and systematic compendium in the field of mycotoxin detoxification.

Zearalenone (ZEA) is a mycotoxin widely occurring in many agricultural commodities. In this study, a purified bacterial isolate, Bacillus sp. S62-W, obtained from one of 104 corn silage samples from various silos located in the United States, exhibited activity to transform the mycotoxin ZEA. A novel microbial transformation product, ZEA-14-phosphate, was detected, purified, and identified by HPLC, LC-MS, and NMR analyses. The isolate has been identified as belonging to the genus Bacillus according to phylogenetic analysis of the 16S rRNA gene and whole genome alignments. The isolate showed high efficacy in transforming ZEA to ZEA-14-phosphate (100% transformation within 24 h) and possessed advantages of acid tolerance (work at pH = 4.0), working under a broad range of temperatures (22–42 °C), and a capability of transforming ZEA at high concentrations (up to 200 µg/mL). In addition, 23 Bacillus strains of various species were tested for their ZEA phosphorylation activity. Thirteen of the Bacillus strains showed phosphorylation functionality at an efficacy of between 20.3% and 99.4% after 24 h incubation, suggesting the metabolism pathway is widely conserved in Bacillus spp. This study established a new transformation system for potential application of controlling ZEA although the metabolism and toxicity of ZEA-14-phosphate requires further investigation.
