  Endophytic Fungi Associated with Mediterranean Plants as a Source of Mycelium-Bound Lipases

  摘要：

  A screening of endophytic fungi isolated from Mediterranean plants rendered a mycelium-bound lipase from a strain of Rhizopus oryzae that catalyzed the esterification of fatty acids in isooctane. The influence of various factors (water content, temperature, and pH) on ester synthesis was investigated. Catalytic activity was inversely correlated with water content. This enzyme was active over the entire pH range studied, from pH 3 to pH 8, and activity was maximal at pH 4 and pH 7. The enzyme was thermostable, with maximal activity at 60 degreesC.

  A method for mixing fluids that can control mixing characteristics of fluids, a method for producing particulates that can provide desired particulates, and particulates produced thereby are provided. According to an embodiment of the present invention, in a method for mixing at least two kinds of fluids in a microreactor, a first fluid is supplied to a mixing zone through a divided supply passage, and a second fluid is supplied to the mixing zone through a supply passage. A total value of dynamic pressures of the first and second fluids is controlled to mix the first and second fluids in the mixing zone. Then, the mixed fluids are flowed into a micro passage.

  A method for increasing ozone concentration in a liquid can include: providing a gas having ozone; introducing the ozone-containing gas into a liquid, wherein the liquid and ozone combination has a temperature between about 0.8 and about 1.5 times the critical temperature of ozone; and increasing isothermally, the pressure of the ozone-containing gas above the liquid to about 0.3 to about 5 times the critical pressure of ozone so as to increase the ozone concentration in the liquid. The temperature is expressed in absolute units (Kelvin or Rankin). The method can be used for removing ozone from a gas or for purifying ozone. The liquid having a high ozone concentration can be used for ozonolysis of a substrate.
