Biodegradable Biopolymers: An Overview On Polyhydroxyalkanoates

Production of Polyhydroxyalkanoates, a bacterial biodegradable polymer

There has been considerable interest in the development and production of biodegradable polymer to solve the current problem of pollution caused by the continuous use of synthetic polymer of petroleum origin. Polyhydroxyalkanoates (PHAs) are known to be accumulated as intracellular inclusion in some bacteria. The materials properties exhibited by PHAs, ranging from stiff, brittle to rubber-like...

LCA of biodegradable multilayer film from biopolymers

Multilayer films exhibit excellent properties for food packaging. However, existing products are not biodegradable. Conventional plastics, manufactured from fossil fuels, not only consume non-renewable and finite resources, but also impact heavily on waste disposal. A new multilayer film has been developed in the Multibio Project for the production of food packaging. In this paper, the environm...

An Overview on Tuberculosis

بیماری سل یک عفونت باکتریایی مزمن است که توسط مایکوباکتریوم توبرکلوزیس ایجاد شده و توسط تشکیل گرانولوما در بافتهای آلوده مشخص می گردد. شایعترین مکان بروز بیماری، ریه ها می باشند. هر چند که سایر ارگانها نیز ممکن است، درگیر بیماری شوند. سل یک بیماری جدید و ناشناخته نیست. این بیماری در گذشته به عنوان کشنده شماره یک در ایالات متحده محسوب می شد و اکنون نیز به عنوان یک عامل مهم مرگ در کل جهان مطرح است.

Biopolymers: overview of several properties and consequences on their applications

Recently, interest in composite manufacturing has shifted towards the use of natural fibres as reinforcement because of their environmental benefits. The use of a biodegradable matrix is worth considering since this would result in a completely biodegradable composite. In order to assess the most suitable matrix polymer, one must know the properties of the available polymers. Since data tend to...
