Methods Experiment 1 A commercial TPN solution without lipid containing multivitamins was used. A specific number of each test microorganism was added to each 10 mL of the TPN solution and incubated at room temperature. An aliquot of test solution was sampled and inoculated to SCD agar plates at 0 24 and 48 hrs after the addition of the microorganisms. The number of microorganisms was counted as colony forming units. Experiment 2 The other 2 commercial TPN solutions without lipid were supplemented with multivitamins. The pH values of the solutions were adjusted to about or using mol L NaOH. The addition of microorganisms incubation and counting were performed in the same manner. Results Experiment 1 S. aureus S. marcescens and B. cereus did not increase in the TPN solution without lipid containing multivitamins but C. albicans
