先正达种子因其 Enogen 玉米淀粉酶特性（事件 3272）获得了日本和台湾监管机构的进口许可，该特性在乙醇工厂进行的测试中证明了玉米乙醇生产的生产力和可持续性得到提高。这些监管批准允许在日本和台湾进口谷物或副产品，如从含有 Enogen 性状的玉米杂交种中培育出来的干酒糟 (DDG)，用于食品或饲料。此外，与 Agrisure 3000GT 叠加的 Enogen 性状已在日本获得批准。
“As a leader in the development of plant-based solutions, Syngenta is pleased that the Enogen corn trait has been approved by the Japanese and Taiwanese governments,” Syngenta Seeds President David Morgan said in a press release. “We believe our Enogen corn technology will play a vital role in improving ethanol plant productivity and increasing profit potential at a critical time for the ethanol industry.”
Because of its unique characteristics, the Enogen trait can bring direct bottom-line benefits to an ethanol industry that is under tremendous strain, Syngenta says. Based on commercial scale trial and process modeling, Syngenta’s analysis of the Enogen trait’s potential indicates that it could mean an additional 8 to 15 cents or more of value per gallon of ethanol produced, and the value creation is driven by a combination of factors such as increased throughput and through reduced water, chemical, and energy requirements, therefore reducing the carbon footprint, according to the company.
除了日本和台湾最近的这些批准外，Enogen 性状（事件 3272）还获准进口到加拿大、澳大利亚、新西兰、墨西哥和菲律宾，Enogen 玉米杂交种自 2008 年以来已获准在加拿大种植。在美国先正达于2007年完成了与美国食品和药物管理局（FDA）的磋商，美国农业部（USDA）的放松管制仍悬而未决。
在美国放松管制后，Enogen 谷物将根据合同在严格管理的跟踪和追溯系统中生产，以保持干磨乙醇工艺的质量标准，并减少某些工业和食品工艺中淀粉功能影响的可能性。
