A synthesis method of aromatic amino acids according to one aspect of the present invention includes a process of preparing thermostable enzyme, a process of amino-transferring reaction and a process of product precipitation and enzyme recycling. These are cumbersome to manufacture, requiring many manual processes. A mechanical connection is also provided between the lever and the drawer and between the lever and the dispensing member, so that operation of the lever causes the drawer to move from the loading position to the brewing position and the dispensing member to rest against the single serving package. The corn grain generally includes the steps of flaking corn grain having a total oil content of at least about 8% and extracting a corn oil from the flaked corn grain. BLVR can be carried out by collapsing a region of the lung, adhering one portion of the collapsed region to another, and promoting fibrosis in or around the adherent tissue. The outlet is opened to an axial end of the bearing body for allowing the lubricating oil in the oil groove to be discharged from the bearing body.
