citrinum CBMAI 1186 were used as biocatalysts in the chemoselective biotransformation of the carbon–carbon double bond in α,β-, di-α,β-, and mono-α,β,γ,δ-unsaturated ketones (3a, 3c–f) in a biphasic system of phosphate buffer and n-hexane (9:1). Only the di-α,β,γ,δ-unsaturated ketone (3b) was not biocatalyzed under these conditions. In general, there were good conversions of saturated ketones by the
为了扩大海洋真菌柠檬青霉CBMAI 1186介导的还原反应在有机化学过程中的适用范围,用丙酮,乙酸乙酯,正丁醇,二氯甲烷,ñ正己烷和甲苯。ñ -己烷根据菌丝团的与各溶剂混合的人造海水的培养基中生长的量最小毒性的溶剂。因此,柠檬青霉的整个菌丝CBMAI 1186用作α,β-,di-α,β-和单α,β,γ,δ-不饱和酮中的碳-碳双键化学选择性生物转化的生物催化剂(3a,3c-f)在磷酸盐缓冲液和的双相系统ñ正己烷(9:1)。在这些条件下,只有二α,β,γ,δ不饱和酮(3b)未被生物催化。一般而言,有由的烯酸还原酶酶饱和酮的良好的转化率P.桔CBMAI 1186。
