According to a report by Reuters, a recent study by Norwegian scientists found that an enzyme helps to decompose chitin in cells. The chemical reaction produced by this enzyme can extract organisms from plants such as sugarcane and waste from other trees. fuel. Gustav Vaaje-Kolstad of the Norwegian University of Life Sciences hosted the study and his colleagues published the results of their research in the journal Science.
In the lab near Oslo, Gustav showed a small vial of gray liquid, which is a sample of enzymatic decomposition of chitin, while the other bottle is a chitin sample without added enzyme catalyst. Ding quality is also well preserved in the clear liquid. Gustav said: "The purpose of our research is to produce more valuable products from waste."
Chitin, also known as chitin, is a protective translucent hard substance that is essentially a nitrogen-containing polysaccharide. This hard material, similar to wood fiber, is also present in crustacean organisms such as lobsters or crabs. And among the insect skeletons, chitin is a major component of the arthropod exoskeletons and some of the fungal cell walls.
Gustav said: “One of the most important bottlenecks in the production of second-generation biofuels is the decomposition of a certain amount of biological substances into the chemical reaction of sugars.†And this enzyme appears to be able to expand and decompose woody materials. Therefore, Gustav and his colleagues published an article in Science, saying: "Strong evidence shows that similar enzymes also have such effects in fibers."
In addition, there are many other scientists who are studying various methods and hope to create a new generation of bio-oil from waste. The widespread use of bio-fuels will help to slow down the global warming trend caused by petroleum fuels.
It is easier to directly produce biofuels from crops such as sugarcane, sunflower, or corn, but it also means that it consumes large amounts of food, causing contradictions between fuel production and food supply.
The enzyme used by Gustav is Serratia marcescens, a gram-negative bacillus that produces a chemical reaction on the chitin surface of organisms, enabling chitin to further Decomposed by other enzymes.
Gustav said that the use of this enzyme can break down chitin in two hours, and that the old method they discovered five years ago would take 48 hours to achieve the same effect.
However, he also stated that the current experimental study needs to be replicated on a larger scale. He said: “We currently only complete this response on the laboratory scale, but we may not be able to apply it to larger-scale production. But we have great hope and confidence in this."
TPO Waterproofing Membrane is an advanced-formula, heat-weldable Waterproofing Membrane Specification TPO or thermoplastic polyolefin is a single-ply reflective Roofing Membrane. It is composed of polypropylene and ethylene-propylene rubber which are polymerized together to form what we call TPO. This synthetic roofing membrane comes in various thickness and dimensions.
PVC Waterproofing Membrane is an advanced-formula, heat-weldable PVC thermoplastic membrane that is designed for long-term weather-ability and performance. The physical properties of the membrane are enhanced by a tenacious, weft-inserted polyester fabric that is encapsulated by thick PVC- based top and bottom plies.
The smooth surface of the PVC membrane allows for a total-surface fusion and permanent weld, creating a consistent, watertight, monolithic roof assembly. PVC can be used in adhered and mechanically fastened systems.
For contiguity of the PVC membrane, a special laminated plate is used. Lamination is carried out by spraying
of the PVC on the metal surface. When welding the membrane to the laminated sheet. We obtain an unbreakable monolith.
