测试了四种酵母（酿酒酵母、粟酒裂殖酵母、产朊假丝酵母和圆红酵母）生长和消耗D-葡萄糖、D-木糖、D-木酮糖和D-木糖醇的能力。当D-葡萄糖与D-木酮糖混合作为C源时，发生底物的顺序利用。初步推断，分解代谢物抑制是这种调节机制的原因。D-葡萄糖抑制C. utilus和R.圆酵母。D-木糖、D-木糖醇和D-木酮糖同时被R. toruloides和C. utilus。
Four yeasts (Saccharomyces cerevisiae, Schizosaccharomyces pombe, Candida utilus and Rhodotorula toruloides) were tested for their ability to grow and consume D-glucose, D-xylose, D-xylulose and D-xylitol. Sequential utilization of substrates occurred when D-glucose was mixed with D-xylulose as the C source. Catabolite inhibition was tentatively concluded to be responsible for this regulatory mechanism. D-Glucose inhibited the utilization of D-xylose and D-xylitol in C. utilus and R. toruloides. D-Xylose, D-xylitol and D-xylulose were consumed simultaneously by R. toruloides and C. utilus.
