摘要

念珠菌在细胞生长过程中向培养基中释放多种多糖。在本文中，我们首次报道了利用这些多糖作为原料制备生物聚合物薄膜。用FTIR和1H-NMR对制备的薄膜进行了结构表征。XRD和热分析测试表明，这些薄膜是无定形的，玻璃化转变温度为- 25℃。拉伸试验表明，NCP薄膜与其他天然生物聚合物薄膜具有相似的力学性能。这些结果表明，这些NCP薄膜可用于开发新的生物聚合物材料，在食品和生物医学工业中具有潜在的应用前景。

Preparation and Characterization of Polysaccharide Films from the Cyanobacteria Nostoc commune

Nostoc Commune bacteria release a variety of polysaccharides into the culture medium during cell growth. In this paper we report, for the first time, the use of these polysaccharides as a raw material for the preparation of biopolymeric films. The structural characterization of the films prepared was assessed by FTIR and 1H-NMR. XRD and thermal analysis tests showed that these films are amorphous and have a glass transition temperature of −25°C. Tensile tests showed that NCP films displayed a similar mechanical behavior in comparison with other natural biopolymer films. These results suggest that these NCP films can be used for the development of new biopolymeric materials with potential applications in the food and biomedical industries.

期刊介绍： Polymers from Renewable Resources, launched in 2010, publishes leading peer reviewed research that is focused on the development of renewable polymers and their application in the production of industrial, consumer, and medical products. The progressive decline of fossil resources, together with the ongoing increases in oil prices, has initiated an increase in the search for alternatives based on renewable resources for the production of energy. The prevalence of petroleum and carbon based chemistry for the production of organic chemical goods has generated a variety of initiatives aimed at replacing fossil sources with renewable counterparts. In particular, major efforts are being conducted in polymer science and technology to prepare macromolecular materials based on renewable resources. Also gaining momentum is the utilisation of vegetable biomass either by the separation of its components and their development or after suitable chemical modification. This journal is a valuable addition to academic, research and industrial libraries, research institutions dealing with the use of natural resources and materials science and industrial laboratories concerned with polymer science.
