Once enough mycelial mass was obtained, the samples were placed in 2000 mL beakers and blended at 3000 rpm with an electric manual whisk previously sterilized with alcohol.
WebMay 1, 2014 · A biotechnology-based process, called biopulping, has been developed to eliminate the use of these environmentally harsh compounds. Biopulping is based on enzymes which selectively degrade and dissolve the wood gluing compounds. The mechanism is much like the conventional chemical process but without the need for high … Webcommercial operation of the process. Based on the electrical energy savings and the strength improvements, the process economics looks very attractive. Several independent economic evalua tions of biopulping have now been completed by both university and industry economists and engineers and are in agreement.
WebPulping and Bleaching Processes Pulp is produced from wood by either chemical delignification, mechanical separation of the cells (fibers), or combinations of chemical and mechanical methods. Mechanical pulping methods give much higher yields (80–95% based on the wood) than the chemical methods (40–50% yields).
