According to a study reported by the University of Wolverhampton scientists at the Fall Meeting of the Institute of General Microbiology on September 3, the use of a bacterium that uses waste cooking oil, commonly known as cooking oil, as a raw material can be synthesized with higher efficiency. Biodegradable bioplastics, once scaled up, can not only reduce environmental pollution but also provide medical implants with suitable high quality plastics.
The polyhydroxyalkanoate (PHA) family synthesized by a variety of bacteria is a biodegradable bio-plastic, of which poly-3-hydroxybutyrate (PHB) is the most commonly used, and promotion of this biodegradable plastic will help reduce environmental pollution. .
At present, the raw material used by bacteria to produce this high-quality bioplastic in large-scale fermenters is glucose, which has a high cost and severely restricts the commercialization of bioplastics. New research shows that the use of waste cooking oil as raw material can reduce the cost of plastic production.
The researchers explained: “We produce bioplastic bacteria, Ralstonia strain H16, which produces 3 times more PHB in oil than glucose in more than 48 hours. In collaboration with the University of Birmingham, UK The results of electrospinning experiments showed that the plastic nanofibers produced in oil have very low crystallinity, which means that the plastic is more suitable for medical applications.†Previous studies have shown that PHB is biodegradable and non-toxic, Microcapsules that can be used as drug delivery in the treatment of tumors can also be used as medical implants.
The next challenge for the research team is to appropriately expand the scale of the trial to achieve large-scale production of bioplastics in the industrial sector.

The cover glass is covered on the material on the glass slide, which can avoid the contact between the liquid and the objective lens, so as not to contaminate the lens, and can make the top of the observed cells in the same plane, that is, the distance from the objective lens is the same, so that the observed Images are clearer.Why do you need a coverslip when using a microscope
1. Make the object to be observed form a thin film, which is easy to transmit light and easy to observe;2. Make the specimen relatively fixed;
3. It is convenient to use the capillary phenomenon to form a gradient when adding various reagents (staining agent, acid, salt solution);
4. Avoid contamination of the specimen.
The purpose of staining the specimen with iodine solution is to make the cells more obvious under the microscope, and it can also kill the cells and prevent the cells from migrating.
