在植物微生物燃料电池中，必须创造有利于植物生长和电力生产的阳极条件。其中的主要方面之一是植物生长介质的成分。迄今为止，一直使用 Hoagland 介质，添加磷酸盐缓冲液，以减少由于阳极和阴极之间 pH 值差异而导致的膜上潜在损失。我们开发了一种新的、改进的植物生长培养基，可以提高当前的产量，同时使植物保持生长。该培养基是一种不含硝酸盐、富含铵的培养基，含有植物生长所需的所有常量和微量营养素，以及均衡量的碳酸氢盐缓冲液。植物生长介质中存在的硫酸盐有助于保持低阳极电位。使用新的植物生长培养基，植物微生物燃料电池的最大电流产量从 186 mA/m(2) 增加到 469 mA/m(2)。 (C) 2011 Elsevier Ltd. 保留所有权利。
In a Plant-Microbial Fuel Cell anode-conditions must be created that are favorable for plant growth and electricity production. One of the major aspects in this is the composition of the plant-growth medium. Hoagland medium has been used until now, with added phosphate buffer to reduce potential losses over the membrane because of differences in pH between anode and cathode. We developed a new, improved plant-growth medium that improves current production, while the plant keeps growing. This medium is a nitrate-less, ammonium-rich medium that contains all macro- and micro-nutrients necessary for plant growth, with a balanced amount of bicarbonate buffer. Sulphate presence in the plant-growth medium helps to keep a low anode-potential. With the new plant-growth medium the maximum current production of the Plant-Microbial Fuel Cell increased from 186 mA/m(2) to 469 mA/m(2). (C) 2011 Elsevier Ltd. All rights reserved.
