“…Optimizing the system would thus demand even shorter light paths than used in this study, an enormous challenge for the open raceway ponds normally suggested for algae growth. This was confirmed by Chatterjee et al. (2019) in a pilot study of a 0.5 m deep raceway pond, where extremely high dilution was required even for only 50% nitrogen recovery.…”

“…For example, Chatterjee et al . grew Scenedesmus acuminatus in human urine for nutrients recovery and found that not all of the nitrogen and phosphorus can be removed even under the optimized conditions . Hence, low treatment efficiency is another challenge to the use of microalgae‐based BLSS for waste remediation in manned spacecraft.…”

Bioregenerative life support system (BLSS) plays a key role in the long‐duration manned space mission. Microalgae‐based BLSS was proposed decades ago but it had a variety of technical problems hindering its application in space mission. However, in recent years, a lot of effort has been devoted to this field and great progresses have been achieved in the research of microalgae‐based BLSS. Therefore, the main aim of this work is to summarize the previous progress and find the challenges faced by microalgae‐based BLSS technology. In this regard, this works introduces the concept of microalgae‐based BLSS and presents its development paths in the past decades. Additionally, technology updates in the aspects of microalgae‐based oxygen generation, value‐added biomass production as food alternative, and wastes treatment by microalgae are summarized. Challenges faced by microalgae‐based BLSS and potential solutions are discussed. This work provides a deep understanding of microalgae‐based BLSS and that it would be beneficial for promoting implementation of this novel technology in manned space missions. © 2019 Society of Chemical Industry

“…An unofficial Scopus search of the literature on "(Micro)algae" and "Urine" was carried out for the timeline from 2000 to 2022 (Figure 1), with the results demonstrating a quick increase in the publication number in the past decade. While recent progress in microalgae breeding and reactor design has improved the economic and process efficiencies of biomass production on human urine (Yang et al, 2011;Chatterjee et al, 2019), there are still challenges in bringing this idea into fruition, including low-cost recovery of microalgae cells, high-efficient extraction of the biofuel, and scale-up of the photobioreactors.…”

Microalgae production in human urine: Fundamentals, opportunities, and perspectives

The biological treatment of source-separated human urine to produce biofuel, nutraceutical, and high-value chemicals is getting increasing attention. Especially, photoautotrophic microalgae can use human urine as media to achieve environmentally and economically viable large-scale cultivation. This review presents a comprehensive overview of the up-to-date advancements in microalgae cultivation employing urine in photobioreactors (PBRs). The standard matrices describing algal growth and nutrient removal/recovery have been summarized to provide a platform for fair comparison among different studies. Specific consideration has been given to the critical operating factors to understand how the PBRs should be maintained to achieve high efficiencies. Finally, we discuss the perspectives that emphasize the impacts of co-existing bacteria, contamination by human metabolites, and genetic engineering on the practical microalgal biomass production in urine.
