Dairy leuconostocs are frequently used as aroma-producing bacteria in mesophilic cultures used as starters for milk fermentations. Sixty Leuconostoc strains from different culture collections were studied taxonomically for species identification. Based on morphological, physiological and biochemical tests, twenty of these strains were typed as Leuconostoc mesenteroides ssp. cremoris (Leu. cremoris)....
Gas mixing is studied in fluidized beds of large particles. The
bed is 0. 483 m by 0. 127 m (19 in. by 5 in. ) in cross section and has
transparent plexiglass panels on the front and back. A tube matrix
made of twenty-seven 50.8 mm (2 in.) diameter...
The effects of mass flow rate and subchannel configuration on
the turbulent interchange between adjacent subchannel in simulated
rod bundle were investigated.
The simulated rod bundle was made by arranging seven 1.913 cm
diameter acrylic plastic rods in an equilateral triangular pattern in a
tube 8.89 cm inside diameter.
The...
Sulfur content in fuel is an increasingly important environmental concern. A
commonly used method for the removal of sulfur bearing species from fuel is
through hydrodesulphurization. However, due to the implementation of Ultra-Low
Diesel Sulfur (ULDS), deeper desulphurization techniques must be explored. In this
study, a single phase oxidative desulphurization...
Microscale reactors operate in sub millimeter space dimensions. Their small length scale enables process intensification of mass, heat and momentum transport that influence reaction rates. Hence it's possible to observe the true intrinsic reaction kinetics occurring for a set of reactions. In this work a novel microscale reactor for producing...
