| Abstract | |
The urban waste has been described as one of the largest environmental pollutants. The plastic garbage can represent up to 20% of the volume of household waste. As an alternative to petrochemical plastics, plastic products less damaging to the environment and more biodegradable have been studied, among them polyhydroxyalkanoates (PHA). The PHA is a biodegradable polyester material accumulated as a reserve material by many bacteria and they have very broad commercial applicability. Recently, the actinomycetes have been studied for the production of polymers. In previous work, 53 new strains of actinomycetes producers of polymers were isolated from soil. In this work the bacterial the selection of bacteria was made concerning the polymers production on different carbon. Of the four strains selected, two were analyzed for the production of a new polymer. In the other two strains were amplified and studied the genes of polymers synthases. In all lineages were analyzed taxonomically and in cultivation on industrial waste. (AU) | |
