    Just change the structure of the cells, can let the electrical cell microorganisms "power generation enthusiasm" high, the efficiency multiplied, devour more garbage and turn it into treasure? Recently, the new issue of Nature Communications published online the latest research results of Professor Song Hao's team in tianjin University's School of Chemical Engineering. This research solves the important scientific problems in the field of microbial electrochemistry, and provides a feasible idea for improving the efficiency of extracellular electron transmission of electrical microorganism cells and promoting the industrialization application of electrical cell microorganisms.according to
    , the process of microbial electro catalysis is a two-way electron and energy exchange process between electrical cells and the outside environment with the help of cell charge and discharge, which has a wide range of applications in energy, environment, chemical industry, military and other fields
    China
    This process enables "waste-for-treasure" applications in the field of environmental energy, such as microbial fuel cells that promote the degradation of organic waste and energy recovery, microbial electrolytic cells for the treatment of hydrogen from wastewater in animal husbandry, brewing and food processing industries, microbial electrosynthetics for reducing carbon dioxide, and the synthesis of high value-added fine chemicals.
    microbial electro catalytic system (microbial electrogenesic, microbial electrosynthesis, microbial unbalanced electrofermentation, etc.) is emerging as a new green new energy production method. At present, cell electron transmission efficiency is too low, which is the biggest bottleneck to limit the application of microbial industrialization of electrical cells. How to use electricity cells to generate electricity efficiently has become a difficult problem that scientists can't wait to solve. Song Hao's team used the modular engineering of synthetic biology to transform the cell strategy, and systematically optimized and reconstructed the metabolism of Shiva bacteria, and modified its genetic genes. "We found that the size of the 'electronic pool' in electrical cells is a key factor in limiting the rate of extracellular electron transmission." Song Hao likened the cell's electronic carrier, NAD, to the cell's internal "battery", whose capacity directly affects the cell's electrical efficiency. Experiments also show that by increasing the total amount of in-cell electronic carrier NAD plus, strengthening the substrate consumption rate, can significantly improve the rate of cell electron transmission, and thus stimulate electrical cell microorganisms more efficient "into work."
