The capacity of several strains of yeasts to do the bioconversion of methyl ricinoleate into gamma-decalactone, was studied in a medium containing this methylic ester of fatty acid as sole carbon source. Amongst the strains which are able to do this bioconversion, two types of behaviour are observed: some of the strains produce gamma-decalactone during all the incubation in bioconversion medium while others produce this aroma compound very quickly and then consume it fast too. The tested strains produce at the same time gamma-decalactone and the corresponding acid form (4-hydroxy-decanoic acid), and this, in variable proportions.
在以脂肪酸甲酯作为唯一碳源的培养基中，研究了几种酵母菌株将蓖麻油酸甲酯生物转化为γ-癸内酯的能力。在能够进行这种生物转化的菌株中，观察到两种行为类型：一些菌株在生物转化培养基的整个培养过程中都产生γ-癸内酯，而另一些菌株则非常迅速地产生这种香气化合物，然后也很快将其消耗掉。受试菌株同时产生γ-癸内酯和相应的酸形式（4-羟基癸酸），且比例各不相同。
