Physical and Chemical Properties of Polyhydroxyalkanotes Biodegradable Polymers Produced in Transgenic Yeasts
نویسنده
چکیده
Polyhydroxybutyrate Homopolymers (PHB) were produced by transgenic yeasts Saccharomyces cerevisiae INVSc1/PHA1 and Schizosaccharomyces pombe Q01/PHB equipped in their cytoplasm and chromosome with the phaABC operon of the PHA biosynthetic pathway of Ralstonia eutropha, respectively. Re The polyesters were purified and physically characterized by Differential Scanning Calorimetry (DSC) and Infrared Spectroscopy (IR). The physical properties of the PHB homopolymers were dependent on the type of transgenic yeast.

Biosynthesis of polyhydroxyalkanotes in wild type yeasts.
Biosynthesis of biodegradable polymers polyhydroxyalkanotes (PHAs) have been studied extensively in wild type and genetically modified prokaryotic cells, however the content and structure of PHAs in wild type yeasts is not well documented. The purpose of this study was to screen yeast isolates collected from different ecosystems for their ability to accumulate PHAs. Identification of the isolat...
متن کاملThe second green revolution? Production of plant-based biodegradable plastics.
Biodegradable plastics are those that can be completely degraded in landfills, composters or sewage treatment plants by the action of naturally occurring micro-organisms. Truly biodegradable plastics leave no toxic, visible or distinguishable residues following degradation. Their biodegradability contrasts sharply with most petroleum-based plastics, which are essentially indestructible in a bio...
متن کاملShelf Life Extension of Package’s Using Cupper/(Biopolymer nanocomposite) Produced by One-Step Process
ABSTRACT: The use of new compounds to increase the shelf life of more perishable foods based on nanoparticles and biodegradable polymers have been developed in packaging. Chitosan (Cts) is a natural biopolymer with excellent biodegradability and nontoxicity and antibacterial effect. In this research antibacterial copper nanoparticles (CuNPs) were incorporated in the biodegradable chitosan matri...

In this study, stable lattices of terpolymer butyl acrylate, methyl methacrylate, and styrene were synthesized by a mini-emulsion polymerization technique using tert-butyl hydroperoxide TBHP/Fe2 /ethylenediaminetetraacetic acid/sodium formaldehyde sulfoxylate redox initiators at room temperature, and the kinetics of the reaction were studied. The reaction rate was obtained from periodic samplin...
متن کاملPreparation of Biodegradable Low Density Polyethylene by Starch – Urea Composition for Agricultural Applications
It has been proven that polyolefins specially low density polyethylene (LDPE), are resistant against degradation and microorganism attacks; Thus, one of the most important properties of industrial plastics, is their environmental biodegradability. Since plastics are being widely used in agriculture, horticulture and packaging, meeting this requirement becomes increasingly dificult (speciall...
