Microdevices for generation of two-phase and three-phase slug flows coupled with an enzyme reaction
Original language description
We developed slug-flow microfluidic systems for the enzyme hydrolysis of soybean oil. Because the enzyme, lipase, catalyzes various reactions at the water-oil interface, the use of well-defined slug flow microsystems can bring a promising alternative toclassical systems. Two developed systems exploit biphasic oil-water slug flow formed in glass and teflon microcapillaries. The remaining system is able to generate stable three-phase slug flow nitrogen-(oil-water). Generation and characterization of theunique three-phase slug flow system are described in detail. It was found that the most stable oil-water slug flow can be realized by means of hydrophilic glass capillaries with the oil conversion about 30 % within 20 min. The highest triglyceride conversion (more than 40 % within 20 min) was attained in hydrophobic capillaries with instable two-phase slug flow. We identified the viscous stress to be the source of slug flow instabilities in the hydrophobic capillaries. The three-phase fl
