我们过去的工作表明,真菌和亚硝胺的形成有关。本文进一步论述真菌在亚硝胺及其前体物合成上所起的作用,证明林县某些常见真菌能还原硝酸盐为亚硝酸盐,并首次报道真菌能利用一级胺或无机胺合成二级胺,还能利用一级胺和NaNO_2合成亚硝胺。特别是一些不对称的亚硝胺和环状亚硝胺,如:甲基异戊基亚硝胺,甲基苄基亚硝胺,亚硝基哌啶和两种新亚硝胺(N—3—甲基丁基—N—1—甲基丙酮基亚硝胺和N—2—甲基丙基—N—1—甲基丙酮基亚硝胺)均可由真菌利用相应的一级胺和Na—NO_2来合成。对真菌利用一级胺合成亚硝胺的可能途径也进行了探讨。
Our past work showed that the fungus is related to the formation of nitrosamines. This article further discusses the role of fungi in the synthesis of nitrosamines and their precursors, and proves that some common fungi in Linxian can reduce nitrates to nitrite, and for the first time reported that fungi can use primary amines or inorganic amines to synthesize two Amine can also use primary amines and NaNO2 to synthesize nitrosamines. In particular, some asymmetric nitrosamines and cyclic nitrosamines, such as methyl isoamyl nitrosamine, methyl benzyl nitrosamine, nitroso piperidine and two new nitrosamines (N— 3-methylbutyl-N-1-methylacetonyl nitrosamines and N-2-methylpropyl-N-1-methylacetonyl nitrosamines can both utilize the corresponding primary amines and fungi. Na-NO2 for synthesis. Possible pathways for the synthesis of nitrosamines from fungi using primary amines have also been explored.
