[Carbohydrate assimilation by clinical and environmental Rhodotorula glutinis strains].
This study was carried to determine the carbohydrate assimilation patterns of Rhodotorula strains isolated from clinical and environmental specimens. We have tested the commercial system ID 32C (bioMerieux, France) on 80 different strains of Rhodotorula glutinis: 47 strains from clinical samples and 33 strains from environmental samples. The assimilation percentages obtained in our study for galactose, cellobiose, gluconate and sorbose were lower than those showed in the identification table of the method. However, the assimilation percentages for mannitol and esculin were higher. According to our results, we conclude that the numerical profiles and the identification software of the commercial system present limitations for the characterization of some R. glutinis strains.
