暗发酵产酸废水作为增磷有机液肥的潜在应用。
本研究建立了一个可持续的综合框架,通过将生物氢(bio-H₂)生产与农业应用的有机养分恢复相结合,最大限度地提高原料的价值。这项研究分两个连续的阶段进行。在第一阶段,利用食物垃圾作为底物在混合半中试规模的生物膜反应器中进行暗发酵。该系统实现了大约85 L的累积生物h₂产量,同时产生14112 mg/L的挥发性脂肪酸(VFAs)。鉴定出的主要发酵代谢物为醋酸盐、丁酸盐和丙酸盐,表明其产酸活性稳定,底物转化效率高。在第二阶段,对富vfa的产酸废水(AE)作为鹰嘴豆(Cicer arietinum)栽培中磷酸盐增溶剂的农艺潜力进行了评估,该排放物代表生物h₂过程的液体部分。为了评估vfa介导的增溶作用,将不溶性磷源磷酸三钙[Ca₃(PO₄)2]掺入土壤中。在整个生长期间,定期补充用水稀释的AE。结果表明,定期添加AE显著提高了磷的增溶和吸收,磷积累量比对照增加了2.45-3.01倍。这种养分利用率的提高转化为植物活力和整体生长性能的提高。总的来说,这些发现突出了AE作为传统磷肥增溶生物肥料的可持续替代品或补充的潜力,从而将可再生能源生产与有机农业系统中的循环养分管理联系起来。

期刊介绍: Bioprocess and Biosystems Engineering provides an international peer-reviewed forum to facilitate the discussion between engineering and biological science to find efficient solutions in the development and improvement of bioprocesses. The aim of the journal is to focus more attention on the multidisciplinary approaches for integrative bioprocess design. Of special interest are the rational manipulation of biosystems through metabolic engineering techniques to provide new biocatalysts as well as the model based design of bioprocesses (up-stream processing, bioreactor operation and downstream processing) that will lead to new and sustainable production processes. Contributions are targeted at new approaches for rational and evolutive design of cellular systems by taking into account the environment and constraints of technical production processes, integration of recombinant technology and process design, as well as new hybrid intersections such as bioinformatics and process systems engineering. Manuscripts concerning the design, simulation, experimental validation, control, and economic as well as ecological evaluation of novel processes using biosystems or parts thereof (e.g., enzymes, microorganisms, mammalian cells, plant cells, or tissue), their related products, or technical devices are also encouraged. The Editors will consider papers for publication based on novelty, their impact on biotechnological production and their contribution to the advancement of bioprocess and biosystems engineering science. Submission of papers dealing with routine aspects of bioprocess engineering (e.g., routine application of established methodologies, and description of established equipment) are discouraged.
