    描述:
    4-甲基-2-氧代-2H-1-苯并吡喃-7-基壬酸酯 在 lipase from Pseudomonas fluorescens 、 二甲基亚砜 作用下, 以 为溶剂, 生成 羟甲香豆素壬酸

    Effect of Dimethylsulfoxide on Hydrolysis of Lipase
    摘要:
    为了建立工业上可行的反应过程,使用荧光底物研究了添加到水溶液中的二甲基亚砜(DMSO)对脂肪酶水解的影响。 DMSO 提高了几种来自微生物的脂肪酶对 4-甲基伞形油酸的水解活性。发现 DMSO 的效果因脂肪酶的种类而异。确认来自荧光假单胞菌的脂肪酶在 DMSO 溶液中的高稳定性后,在不同 DMSO 浓度下对该脂肪酶水解四种酰基-4-甲基伞形酮进行了动力学研究。添加到水溶液中的 DMSO 对于具有强疏水性的底物会增加该脂肪酶的 Vmax,对于具有相反性质的底物会降低该值。另一方面,DMSO 对每种底物的 Km 影响非常小。荧光研究表明,DMSO 引起脂肪酶色氨酸残基周围的化学环境发生变化。这种构象变化可能是 DMSO 诱导其反应特性改变的原因之一。这些结果表明,添加 DMSO 可能是该酶“溶剂工程”的一种新方法。

  • Methods and device for detection of microorganisms
    申请人:BioControl Systems, Inc.
    公开号:EP0264221A2
    公开(公告)日:1988-04-20
    A device adapted for containing a volume of growth medium and employed for detection of gas produced by a micro­organism or microorganisms putatively contained within a test sample and added to the growth medium, comprising a primary chamber, a dome defined by the top surface of the primary chamber and communicating therewith, the dome establishing a fluid level and adapted for collection of gas produced by a microorganism within the growth medium, and a fill section adja­cent to and communicating with one end of the primary chamber, the fill section spaced apart from the dome and extending above the fluid level, and further defining an opening for the addi­tion of a test sample is disclosed. The device may be sealed by means of a removable closure. An apparatus consisting of an array of substantially identical devices is also disclosed. In addition, methods of using the device and apparatus for detect­ing and estimating numbers of microorganisms, and for analyzing samples putatively containing a microorganism, are disclosed.
