摘要

从大肠结肠炎耶尔森菌(菌株75)中提取光滑形态的酚水提取脂多糖(LPS);o -基团I)在10℃下生长后,含有约40% (w/w)的6-脱氧- l -醛糖。通过提高培养温度,观察到o特异性糖的显著降低。40°C培养的细胞LPS含有约12%的6-脱氧- l -醛糖。在较低温度下生长的细胞的薄切片显微照片显示出与LPS的o特异性侧链相对应的独特层,而在较高温度下生长的细胞则观察到厚度减少。据推测,这种观察结果是由于在较高的培养温度下,o特异性糖的量减少。间接免疫铁蛋白试验结果表明,在37℃时,o特异性多糖层完全覆盖细胞表面。然而,一旦培养温度达到40°C,这一层就不再覆盖所有细胞的整个表面。

Zuckerzusammensetzung des Lipopolysaccharids und Feinstruktur der äußeren Membran (Zellwand) bei Yersinia enterocolitica

Phenol-water extracted lipopolysaccharide (LPS) from Yersinia enterocolitica (strain 75 in smooth form; O-group I), after growth at 10 °C, contains approximately 40% (w/w) 6-deoxy-L-altrose. By increasing the cultivation temperature a significant decrease in the O-specific sugar is observed. LPS from cells grown at 40 °C contains about 12% 6-deoxy-L-altrose.

Thin-section micrographs of cells grown at lower temperatures reveal a distinct layer corresponding to the O-specific side chains of LPS in contrast to cells grown at higher temperatures where a decrease in thickness is observed. It is assumed that this observation is due to the decreasing amount of the O-specific sugar at a higher cultivation temperature. The results obtained by the indirect immunoferritin test indicate that the O-specific polysaccharide layer covers the cell surface completely up to 37 °C. However, this layer no longer covers the entire surface of all cells as soon as an incubation temperature of 40 °C is applied.
