Abstract
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.
