Enzyme upgrade helps solve cellulosic ethanol industry bottleneck

SwrSwrthe straw Novixin supply map, a common raw material for cellulosic ethanol,Swrestimates that global energy consumption is expected to increase by 55% by 2030, and cellulosic ethanol is one of the main sources of sustainable energy that is expectedSwr
The common raw materials used to make cellulosic ethanol are crop straw (corn straw, wheat straw and sugar cane slag), wood chips, energy crops and waste in urban wasteCellulosic ethanol reduces CO2 emissions by more than 90% compared to conventional petroleum fuelsHowever, the relevant technology and technology need to be perfected, the production cost is too high has been to limit its large-scale industrialization bottleneckSwr
According to people familiar with the situation told China Science Daily, in the National Development and Reform Commission led by the development of the bio-industry development "12th Five-Year Plan", in particular, "breakthrough cellulosic ethanol raw material pre-treatment technology, low-cost glycation key technology bottlenecks." Enzymes play an important role in thisSwr"enzyme-free non-alcohol"Swrenzymes are familiar and unfamiliar to people Swr
　　Familiarity is because human survival can not be separated from enzymes Enzymes are biocatalysts that catalyze biochemical reactions in living cells and are a protein Because of the presence of enzymes, the body's metabolism can only be carried out For example, food must be dissolved into small molecules by the action of enzymes in order to be absorbed and utilized by tissues through the intestinal wall Strange because many people don't know much about enzymes Swr
　　It was discovered that the enzyme's great effect simply began to extract enzymes from biology for use in industrial production activities, thus accelerating the production process through catalytic action Swr
　　Compared with other renewable energy and petroleum alternative energy sources, fuel ethanol has developed earlier in China and the market size is larger Swr
　　China's vehicle-fuelethanol industry, which produced 1.8 million tons in 2010, is the third-largest producer and consumer of fuel ethanol after Brazil and the United States Swr
　　McKinsey, a leading global consultancy, said in a report that the commercialization of cellulosic ethanol could replace 31m tonnes of gasoline from 2020, reducing China's oil imports by 10 per cent and generating Rmb32bn a year and 6m jobs by 2020 Swr
　　As a result, Chinese companies in the cellulosic ethanol value chain will be the main beneficiaries, including the 96 billion yuan domestic engineering and construction market and potential international markets, where cellulosic ethanol can reduce CO2 emissions by about 90 million tons per year the production of Swr cellulosic ethanol depends on the participation of enzymes Swr
　　The production of cellulosic ethanol from raw materials will be pre-treated, hydrolysised (also known as enzymatic or glycation), fermentation, distillation four steps In the hydrolysis process, the enzyme breaks down cellulose into monosaccharides and polysaccharides to prepare for the next fermentation Swr cellulase preparations to be rapidly replaced Swr for the cellulosic ethanol industry and developed enzymes in recent years rapid replacement Swr
