PHA - Introduction
PHA(PHA) is a biodegradable polymer, which is polymerized by esterification of hydroxy fatty acid monomers. It has the following properties:
1. Biodegradability: PHA can be decomposed by microorganisms and finally converted into carbon dioxide and water, which is environmentally friendly.
2. Biocompatibility: PHA does not cause significant immune or toxic reactions, so it can be used as a material in tissue engineering and medical fields.
3. Physical properties can be adjusted: PHA with different properties (such as strength, melting point, etc.) can be obtained by adjusting the monomer composition and polymerization conditions during synthesis.
The use of PHAs is very wide, including but not limited to the following areas:
1. Medical applications: PHAs can be used in the preparation of absorbable sutures, bone repair materials and drug delivery systems.
2. Packaging materials: Because PHAs is biodegradable, it can be used to prepare degradable plastic packaging materials to reduce the impact of plastics on the environment.
3. Agricultural applications: PHAs can be used to prepare plant fertilizer coatings and pesticide delivery systems to improve the efficiency and sustainability of agricultural production.
The method of preparing PHA is usually produced by microbial fermentation. Commonly used microorganisms are polyhydroxybutyric acid bacteria (Polyhydroxybutyrate-producing bacterium) and polyhydroxyalkanoyl oxidase (Polyhydroxyalkanoate synthase). These microorganisms can grow using cheap waste or organic waste such as food as a carbon source, and then obtain purified PHA through extraction and purification steps.
PHA is considered to be a relatively safe material from a safety point of view. Most PHA will be metabolized normally by the body after degradation in the body, and will not cause harm to the human body. However, for specific PHA types and applications, more toxicity and biocompatibility studies are still needed to ensure their safety and reliability.
