Enzyme studies of strains of Salmonella typhimurium representing biotypes that utilized D-xylose rapidly (xylose strong) or slowly (xylose weak) showed that they were different in the utilization of D-xylose because the xylose-weak strains were deficient in the transport of D-xylose. This observation is consistent with the idea that strains of the different xylose-weak biotypes, e.g. biotypes 17 to 32, were descended from strains of xylose-strong types, particularly from biotype 1.
对代表利用D-木糖速度快(木糖强)或慢(木糖弱)生物型的鼠伤寒沙门氏菌菌株进行的酶研究表明,它们在D-木糖利用方面存在差异,因为木糖弱的菌株在D-木糖转运方面存在缺陷。这一观察结果与以下观点一致,即不同木糖弱生物型的菌株,例如生物型17至32,是从木糖强类型的菌株,特别是从生物型1的菌株衍生而来的。
