Extraction of peptidoglycan in lactobacillus acidophilus cell wall .
嗜酸乳杆菌细胞壁肽聚糖的分离提取。
Most bacterial cell walls contain a macromolecule called peptidoglycan , which human cells do not make or need .
多数细菌的细胞壁含有一种叫做‘肽聚糖’的高分子,人类细胞则不生产和需要这种物质。
Typical bacteria are unicellular prokaryotic organisms that have no organelles except ribosomes , no membrane-enclosed nucleus and have normal peptidoglycan .
典型的细菌是单细胞型的原核生物,除核糖体外无其他细胞器,无核膜,有肽聚糖。
The cell wall is essential for bacterial life because of its tolerance towards the high internal osmotic pressures . An essential constituent of bacterial cell wall is the peptidoglycan .
