We used multilocus sequence typing (MLST) to analyze the diversity of natural isolates of Saccharomyces cerevisiae, the most important microorganism in alcoholic fermentation. Six loci, ADP1, RPN2, GLN4, ACC1, MET4, and NUP116, in S. cerevisiae genome were selected as MLST markers. To investigate genetic diversity within S. cerevisiae, 42 S. cerevisiae isolated from natural sources in Korea as well as six S. cerevisiae obtained from Genbank and four industrial S. cerevisiae were examined using MLST. Twenty-six polymorphic sites were found in the six loci. Among them, ACC1 had the most genetic variation with eight polymorphic sites. MLST differentiated the 52 strains into three clades. Alcohol fermentation results revealed that S. cerevisiae in Clade III produced less alcohol than those in Clades I and II. These results suggested that MLST is a powerful tool to differentiate S. cerevisiae and can potentially be used to select S. cerevisiae suitable for industrial use.

A 47-year-old man developed chronic alcoholic liver cirrhosis and end-stage renal disease. He underwent blood-type-compatible liver transplantation with a graft from his daughter. After 8 months, sequential ABO-incompatible (ABOi) kidney transplantation was performed, with his brother as the donor (A to O). The patient had anti-A antibody titers (1:256). We performed pretransplant desensitization, including administration of rituximab, mycophenolate mofetil, tacrolimus, and prednisolone 2 weeks before the scheduled transplantation, and plasmaphresis (PP) and administered an intravenous immunoglobulin injection. The patient underwent PP before kidney transplantation until the anti-A antibody titer was <1:8. The patient achieved normal renal function within 4 posttransplantation days. Postoperative bleeding (diffuse hemorrhage) requiring additional blood transfusions and radiological intervention (drainage procedure) occurred 9 days after transplantation. The patient was discharged on day 20 of hospitalization. Nine months after the kidney transplantation, the recipient’s and donor’s liver and kidney functions were normal. ABOi renal transplantation after liver transplantation can be successfully performed in patients with high baseline anti-ABO antibody titers after preconditioning with rituximab and PP, and quadruple immunosuppressive therapy. However, caution is required regarding an increased risk of bleeding complications.
