The carboxylate platform employs a diverse microbial consortium of anaerobes in which the methanogens are inhibited. Nearly all biomass components are digested to a mixture of C1-C8 monocarboxylic acids and their corresponding salts. The methane-arrested anaerobic digestion proceeds readily without needing to sterilize biomass or equipment. It accepts a wide range of feedstocks (e.g., agricultural residues, municipal solid waste, sewage sludge, animal manure, food waste, algae, and energy crops), and produces high product yields. This review highlights several important aspects of the platform, including its thermodynamic underpinnings, influences of inoculum source and operating conditions on product formation, and downstream chemical processes that convert the carboxylates to hydrocarbon fuels and oxygenated chemicals. This review further establishes the carboxylate platform as a viable and economical route to industrial biomass utilization.
羧酸盐平台采用了多种厌氧微生物群落，其中抑制了产甲烷菌。几乎所有的生物质成分都被消化成 C1-C8 单羧酸及其相应的盐的混合物。甲烷截留的厌氧消化过程很容易进行，而不需要对生物质或设备进行消毒。它接受广泛的原料（例如农业残余物、城市固体废物、污水污泥、动物粪便、食物废物、藻类和能源作物），并产生高产品产量。本综述重点介绍了该平台的几个重要方面，包括其热力学基础、接种物来源和操作条件对产物形成的影响，以及将羧酸盐转化为碳氢燃料和含氧化学品的下游化学过程。本综述进一步确立了羧酸盐平台作为一种可行且经济的工业生物质利用途径。
