Abstract

The present study showed that the growth of Streptococcus mutans strain GS5 was inhibited by xylitol, and this indicates together with previous reports that this is a common phenomenon in this species. Sorbitol was found to increase the growth of S. mutans strains OMZ 176 and GS5 slightly compared with cultures with no external carbon source. Addition of small amounts of xylitol to the sorbitol cultures gave a growth below that of cultures with no extra carbon. Dental plaque challenged with sorbitol gave a small pH drop whereas xylitol caused a negligible decrease in pH. Sorbitol-xylitol challenges gave less acid production than sorbitol challenges alone.

摘要

本研究表明，木糖醇可抑制变形链球菌GS5菌株的生长，这与之前的报道共同表明，这是该物种中的常见现象。与无外源碳源的培养物相比，发现山梨醇可使变形链球菌OMZ 176和GS5菌株的生长略有增加。在山梨醇培养物中添加少量木糖醇，其生长低于无额外碳源的培养物。用山梨醇攻击牙菌斑会使pH值略有下降，而木糖醇导致的pH值下降可忽略不计。山梨醇-木糖醇攻击产生的酸比单独用山梨醇攻击产生的酸少。
