As expected, independently of storage conditions, the results show that\u00a0typical field fungi (<\/strong>Alternaria<\/strong>,\u00a0<\/strong>Fusarium<\/strong><\/em>) were gradually replaced by storage fungi (<\/strong>Aspergillus<\/strong><\/em>\u00a0mainly)<\/strong>, though\u00a0Fusarium<\/em>\u00a0first increased, before decreasing until total inhibition.\u00a0<\/p>\r\n\r\n\r\n\r\n DON contamination significantly evolved during storage.<\/strong>\u00a0In the first month of storage, DON level increased by about 14% in all storage conditions. A longer storage had different effects on DON level in the wheat: at 25\u00b0C, the level increased by 36% while it decreased at 30 and 35\u00b0C.\u00a0The change in moisture also stressed DON production<\/strong>: 12% and 15% relative humidity (RH) increased DON levels by circa 67% compared to the 13% RH storage.\u00a0The D3G level was highly associated with DON level<\/strong>\u00a0(D3G being converted from DON) and increased by up to 202% in specific conditions (linked with insect presence for example).\u00a0<\/p>\r\n\r\n\r\n\r\n Figure: Changes in deoxynivalenol (DON) content in wheat under different storage conditions. Adapted from Wang\u00a0et al.<\/em><\/p>\r\n\r\n\r\n\r\n In general, the study indicates that\u00a0the storage conditions and the initial DON load significantly influence the mycotoxin-producing\u00a0<\/strong>Fusarium<\/strong><\/em>\u00a0taxa and change the DON and D3G content<\/strong>. This seems to be correlated with the competition between fungi:\u00a0the more the competition, the higher the DON production<\/strong>.\u00a0<\/p>\r\n\r\n\r\n\r\n Reference:\u00a0Wang R.,\u00a0Mengmeng\u00a0L., Jin R., Liu Y., Guan E., Mohamed S.R., Bian K.\u00a0Interactions among the composition changes in fungal communities and the main mycotoxins in simulated stored wheat grains.\u00a0J Sci Food Agric\u00a02024, 104,\u00a0373-382.\u00a0https:\/\/doi.org\/10.1002\/jsfa.12928<\/a>\u00a0<\/p>\r\n\r\n <\/p>","protected":false},"excerpt":{"rendered":" April 5, 2024 Reading Time:\u00a02\u00a0minutes The global trading of wheat\u00a0and\u00a0its\u00a0subsequent\u00a0transportation\u00a0leads\u00a0to increased storage\u00a0time\u00a0of the grains, which can be at risk for mycotoxins.\u00a0In their\u00a0study, Wang\u00a0et al.\u00a0simulated different storage conditions (time, temperature, humidity,…<\/p>\n","protected":false},"author":16,"featured_media":15913,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[38],"tags":[],"class_list":{"0":"post-12285","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-myco-news-3"},"_links":{"self":[{"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/posts\/12285","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/users\/16"}],"replies":[{"embeddable":true,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/comments?post=12285"}],"version-history":[{"count":5,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/posts\/12285\/revisions"}],"predecessor-version":[{"id":16267,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/posts\/12285\/revisions\/16267"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/media\/15913"}],"wp:attachment":[{"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/media?parent=12285"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/categories?post=12285"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mycokingdom.net\/en\/wp-json\/wp\/v2\/tags?post=12285"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/olmix.com\/wp-content\/uploads\/2024\/04\/image-20.png\")
