摘要： The present invention relates to a process for producing vanillin. Culturing of a basidiomycete fungus of the genus Pycnoporus or of their variants and mutants is performed in a culture medium to which a benzenoid precursor of vanillin has been added, and the vanillin produced by bioconversion of the benzenoid precursor is recovered.

摘要： The present invention relates to a process for producing cis-3-hexen-1-ol from an unsaturated fatty acid, in which said synthesis is carried out from the latter by the combined action of a natural system of enzyme(s) allowing the oxidation of said fatty acid to cis-3-hexenal and of a yeast allowing the reduction of cis-3-hexenal to cis-3-hexenol in a culture medium. According to a first characteristic of the present invention, the enzymatic system consists of a plant mass obtained by grinding leaves harvested whole without predilacerating them. According to a second characteristic of the present invention, the enzymatic system is introduced in the form of a ground cellular product obtained by grinding followed by cell disintegration. Finally, advantageously, a reagent chosen from a ferrous cation, acetylsalicylic acid, chlorophyll B and the enzyme catalase, makes it possible to increase the yields of cis-3-hexenol.

摘要翻译： 本发明涉及从不饱和脂肪酸生产顺式-3-己烯-1-醇的方法，其中所述合成通过允许氧化的酶的天然体系的组合从后者进行 的所述脂肪酸转化为顺式-3-己烯醛，以及允许在培养基中将顺式-3-己烯醛还原成顺式-3-己烯醇的酵母。 根据本发明的第一特征，酶系统由通过研磨叶片的叶片而获得的植物团块组成，而不会使它们前体化。 根据本发明的第二特征，酶系统以通过研磨获得的研磨细胞产物的形式引入，随后进行细胞分解。 最后，有利地，选自亚铁阳离子，乙酰水杨酸，叶绿素B和酶过氧化氢酶的试剂使得有可能提高顺式-3-己烯醇的产率。
