摘要
采用相关标准,对菠萝叶纤维的抗菌性进行测试,从菠萝叶纤维形态结构、化学组成上研究菠萝叶纤维的抗菌作用和机制。结果表明,菠萝叶纤维表面有纵向裂缝和孔洞,比表面积大,易于吸附氧气,破坏了厌氧菌的生存环境;菠萝叶纤维中的酚类物质可能存在于木质素中,可阻碍细菌等微生物代谢作用和生理活动,破坏菌体的结构,最终导致菌体的生长繁殖被抑制。
Antibiotic properties of pineapple leaf fiber were tested and the anti-bacterial mechanism of the pineapple leaf fiber was analyzed from the aspects of the morphological structure and chemical composition of the fiber. The results indicated that pineapple leaf fibers had longitudinal cracks and holes with large specific area and hence easily absorbed oxygen, which broke the survival environment for anaerobic bacteria. The pineapple leaf fiber contained a lot of phenols in lignin which could inhibit the metabolism and physiological activities of microorganisms like bacteria, brok their structures and finally restrained the proliferation of the microorganisms.
