Tomato juice (serum) added to milk in high concentration caused inhibition of acid production by Lactobacillus bulgaricus. The inhibitor was partially purified by adsorption on charcoal. Further isolation and purification involved paper chromatography in two different solvent systems. Ultraviolet-absorption spectra and thin-layer chromatography were used in characterization studies. The inhibitor was found to be a xylose- and adenine-containing nucleotide.
向牛奶中添加高浓度番茄汁（浆液）会抑制保加利亚乳杆菌产酸。通过吸附在木炭上对抑制剂进行部分纯化。进一步的分离和纯化涉及在两种不同溶剂系统中的纸色谱法。利用紫外吸收光谱和薄层色谱进行特性研究。发现该抑制剂是一种含木糖和腺嘌呤的核苷酸。
