| The first set of ethanol production equipment based on xylose residue produced by Shandong Longli Biotechnology Co., Ltd. and Shandong University, passed the technical appraisal on June 21. At the appraisal meeting, experts from Tsinghua University and China Fermentation Industry Association believed that “the production of fiber ethanol from xylose waste residue†reached the domestic leading level and was a typical example of using bio-refining technology to develop circular economy. The direction of the country's industrial development. This achievement introduces the concept of “biorefinery†into the field of biomass resource development, breaking the traditional concept of using pure biomass to produce a single product, and using corncob processing residue as raw material to produce ethanol, its cellulose content is as high as 60%, fiber The conversion rate of the prime has reached more than 86%, and the tested products have reached the quality standard of fuel ethanol, achieving full utilization of raw materials, maximizing product value and maximizing land use efficiency. At the same time, the results avoided the three problems of collection, transportation, pretreatment and pentose utilization of cellulose raw materials. Based on this achievement technology, Longli Company built the first domestic industrial equipment with corncob waste residue as raw material and an annual output of 3,000 tons of ethanol. |
The in vitro culture of cells and tissues has become an indispensable part of life research and practice. A wide variety of cell types are cultured, from viruses to bacteria and fungi, from human cells to animal and plant cells. Some cells and tissues can be grown in suspension, but a considerable number of mammalian cells require surface attachment. Therefore, in addition to good transparency, non-toxicity and sterility, the culture flasks, Culture Plates and culture dishes used to provide the in vitro culture environment of cells also need to be surface-modified to enable them to adhere, divide and grow.
