Until now, it was believed that the polyurethane (polyurethane) is not biodegradable, but a team of
IL1F9 scientists from Yale University found that eating and degradation of fungi, and even in the oxygen does not exist. Amazon is one of the regions most diversity of life on Earth. In 2011, Yale University scientists found microbes in the Amazon to collect plants and cultivate them. Among the cultured microbial samples, they found a degradation of the plastic material polyurethane, fungi, small spore intended disk hairy IL1R1 spore (Pestalotiopsis microspora). Polyurethane is a synthetic polymer of human development in the 1940s and is often used to replace rubber, paint, wood or metal. It is widely used in a variety of modern equipment, furniture, dyes, foam insulation, adhesives, and shoes, while there are many other uses, and it is both the advantages of strength, durability and flexibility. The polyurethane used can be recycled to produce other Il1r2 products, but it will still be waste. Because we know that no energy metabolism and degradation of it (in other words, it is not biodegradable), so once it is in the Landfill, it may be almost indefinitely stay there, and this leads to environmental problems. The polyurethane IL1RAP chemical bond is so strong to the extent that it is not easy degradation.
The polyurethane can be burning, but it will release harmful carbon monoxide into the atmosphere, while producing other toxic chemicals. In 2011, a research team led by molecular biochemist Scott Strobel, professor of small spore intended to disk hairy spore not only eat the IL1RAPL1 polyurethane, and can survive only by the polyurethane composition of the food. Furthermore, it can survive in anaerobic environments, such as its ability to field deep within the hypoxic region exists in the landfill. The fungus is found in the jungles of Ecuador by the Graduate Pria Anand, another graduate student, Jonathan Russell, of in its identification of a serine hydrolytic enzymes, people think it is this enzyme so that the fungi can degrade polyurethane. Study of two graduate students are Yale University molecular physics and biochemistry departments. This newly discovered fungus is an endogenous micro-organisms, which means it lives on or inside the host plant tissue, but not cause harm. They also found several other micro-organisms able to degrade the solid and liquid polyurethane, but only a small spore intended to survival in the plastic disk hairy spore isolates in aerobic and anaerobic conditions. In May 2012, described the discovery of papers published in the journal Applied and Environmental Microbiology. The authors have prompted a similar spore intended disk hairy spore class of endogenous fungi may be used to degrade under natural conditions, such as polyurethane waste products, this process is also known as bio-remediation.
