The occurrence of phosphatidylethanolamine and glycosyl diglycerides in thermophilic bacilli.
Ph 0s p h at id y le t han ol am i n e, a comm o n constituent of the polar 1 i pid s of Gram n ega t i ve bacteria, is consistently found in only one genus of Gram-positive bacteria, the bacilli (Goldfine, 1972). Gram-positive bacteria commonly contain diglycosyl diglycerides (Shaw & Baddiley, 1968; Shaw, I 970) which often occur together with phosphatidylethanolamine in the bacilli. An interr...
متن کاملBritain The Structure and Possible Function of the Glycolipid from Staphylococcus lactis 13
1. The total lipid was extracted from Staphylococcus lactis I 3 with chloroformmethanol mixtures and the glycolipid component was isolated by chromatography on silicic acid. 2. Saponification yielded a non-crystalline glycoside for which the structure O-D-glucopyranosyl-(1 -÷6)-O-fi-D-glucopyranosyl-(1 -*1)-D-glycerol has been established by chemical degradations and by comparison with syntheti...

متن کاملSeparation of Glycosyl Diglycerides from Phosphatides Using Silicic Acid Column Chromatography.
A procedure has been developed for the separation of the glycosyl diglycerides from the phosphatides of Gram-positive bacteria on columns of silicic acid. The method utilizes mixtures of acetone in chloroform for elution of the glycosyl diglycerides, followed by increasing amounts of methanol in chloroform for elution of the phosphatides. The course of the fractionation was followed by means of...
متن کاملبررسی اثر ضد باکتریایی پرده‌های جنینی انسان در محیط آزمایشگاهی
Background and Aim: Studies have shown that probably there are compounds with protective effects on delivery channels and chorionic membranes which prevent the uterus and the embryo from bacterial contamination. The present study aimed to assess anti-bacterial properties of chorionic membranes in comparison with the effects of some common antibiotics . Materials and Methods: This study w...
