    摘要:
    在本研究中,在水性和有机介质中评估了三种生物催化剂的特定水解活性,例如组成型菌丝体结合脂肪酶、诱导菌丝体结合脂肪酶和来自黑曲霉 MYA 135 的冻干诱导上清液。对于相同的水解反应,未观察到水中活性与正己烷之间的直接相关性。正己烷/水活度比 (RO/A) 用于表征有机介质中的活性。三种生物催化剂在水解长链脂肪酸酯时表现出高于 1 的 RO/A 值,表明在有机溶剂中比在水中具有更高的比水解活性。在中链脂肪酸酯的水解过程中观察到不同的行为,在水性介质中更高(RO/A < 1)。使用所有三种生物催化剂制备的不同醇与各种对硝基苯基衍生物的酯交换也在正己烷中进行了评估。对于甲醇分解和乙醇分解,组成型菌丝体结合脂肪酶显示出对 C16 底物(对硝基苯基棕榈酸酯)的有趣偏好。诱导菌丝体结合脂肪酶在水溶性醇和中链脂肪酸酯(对硝基苯基癸酸酯和对硝基苯基月桂酸酯)存在下表现出较高的特异性酯交换活性,具有最高的特异性酯交换活性(91

  • Selective mixed coupling of carboxylic acids (I). - Electrolysis, thermolysis and photolysis of unsymmetrical diacyl peroxides with acyclic and cyclic alkyl groups
    作者:Michael Feldhues、Hans J. Schafer

    日期:1985.1
    dodecanoyl octanoyl peroxide () affords the unsymmetrical coupling product octadecane()ins poor yield and selectivity. Thermolysis or photolysis in solution produces preferentially , but also considerable amounts of disproportionation products. At −78°C the neat peroxides are photolysed selectively to the mixed dimers. With straight chain and β-branched alkyl groups high yields are obtained (63 – 76 %)

    Chrysosporium xerophilum . Sixty per cent of the volatiles were aliphatic methyl ketones (C 5 -C 13 ), esters and secondary alcohols whilst 38% were present as free medium chain length fatty acids (C 6 -C 12 ). A new class of ester, 2-heptyl esters of C 8 ,C 10 and C 12 fatty acids, was identified by GC-MS and confirmed by synthesis. It is suggested that ester formation, ketone formation and alkane synthesis
    摘要 干枯金孢菌将椰子发酵 9 个月后生产了一种精油 (0.3% v/w)。60% 的挥发物是脂肪族甲基酮(C 5 -C 13 )、酯类和仲醇,而 38% 以游离的中链脂肪酸(C 6 -C 12 )形式存在。一类新的酯,即 C 8 、C 10 和 C 12 脂肪酸的 2-庚酯,通过 GC-MS 进行鉴定并通过合成进行确认。建议酯形成、酮形成和烷烃合成是去除中链脂肪酸(C 6 -C 12 )的机制,如果允许其在底物中积累,将对真菌有毒。
