Studies on the Biosynthetic Method and Improvement of Production of Novel Polysaccharides from Living Wastes

采用含葡萄糖培养基对木动杆菌进行反复传代培养，制备n -乙酰氨基葡萄糖（GlcNAc）残基诱导细菌纤维素（2-4摩尔%）。由于以葡萄糖胺或半乳糖胺作为碳源代替葡萄糖nac可使GlcNAc残渣掺入相似水平，但甘露糖胺效果不佳，因此建议脱氨酶参与GlcNAc残渣掺入。考虑到氨离子是脱氨酶的最终产物，采用一种新型的好氧旋转培养装置，将葡萄糖和铵盐成功地应用于葡萄糖nac与细菌纤维素的结合。用浅盘培养器成功地制备了新型纤维性细菌纤维素。这些纤维被证明具有比棉花更高的抗拉强度。

Actobacter xylinum has been subcultured repeatedly to prepare N-acetylglucosamin (GlcNAc) residue induced bacterial cellulose (2-4 mole%) applying GlcNAc containing glucose medium. As a similar level of GlcNAc residue incorporation has been made by applying glucosamin or galactosamin as carbonsource instead of GlcNAc, but mannosamin was not effective, participation of deaminase was suggested on the GlcNAc residue incorporation. Since ammonium ion was assumed to be final product by deaminase, gulucose and ammonium salts were applied successfully to incorporation of GlcNAc into bacterial cellulose by applying a new type of aerobic rotatory cultivator. A shallow pan cultivator has been made to prepare fibrous novel bacterial celluloses successfully. These fibers were shown to have higher tensile strength than that of cotton.
