From urine to food and oxygen: effects of high and low NH4 +:NO3 - ratio on lettuce cultivated in a gas-tight hydroponic...
Published in Frontiers in Plant Science
In situ production of food, water and oxygen is essential for long-duration human space missions. Higher plants represent a key element in Bioregenerative Life Support Systems (BLSS), where crop cultivation can be based on water and nutrients recovered from waste and wastewater. Human urine exemplifies an important waste stream with potential to pr...

Chenopodium quinoa Willd. is a native species that originated in the High Andes plateau (Altiplano) and its cultivation spread out to the south of Chile. Because of the different edaphoclimatic characteristics of both regions, soils from Altiplano accumulated higher levels of nitrate ( NO 3 − ) than in the south of Chile, where soils favor ammonium...
Evaluation of ammonium issues in Indonesian groundwater: Potential sources and removal methods
Published in IOP Conference Series: Earth and Environmental Science
Elevated concentration of ammonium (NH4 +) has been identified as one of the problems with groundwater because it indicates anthropogenic disturbance. In this study, we evaluated the NH4 + presence in Indonesian groundwater and the land-use conditions possibly related to the issues. In addition, this research presents practical strategies for reduc...
Groundwater nitrogen concentration changes in an urbanized area of Indonesia over ten years period

Published in IOP Conference Series: Earth and Environmental Science
Nitrogen in groundwater poses environmental concerns in Bandung Region, Indonesia, due to natural and anthropogenic factors. The predominant component of the region’s aquifer is high-hydraulic-conductivity volcanic rock, one of the natural vital factors that make the aquifer vulnerable to contamination. Another factor is urbanization which has been...

Introduction The production of root exudates with biological nitrification inhibition (BNI) effects is a strategy adopted by ammonium-N ( N H 4 + ‐ N ) tolerant plant species that occur in N-limited environments. Most knowledge on BNI comes from plant species that occur in acidic soils. Methods Here, combining field sampling and laboratory culture,...
Removal of ammonium and manganese from surface water using a MeOx filter system as a pretreatment process.
Published in Environmental technology
Residual aluminium from the coagulation-sedimentation process in the treatment of surface water can decrease the catalytic activity of a manganese co-oxide filter film (MeOx) used for ammonium and manganese removal. To solve this problem, a MeOx filter was used as a pretreatment process to filtrate source water directly before the coagulation and s...

Published in Frontiers in Marine Science
Introduction In marine ecosystems, microbial communities are important drivers of material circulation and energy flow. The complex interactions between phytoplankton and bacterial communities constitute one of the most crucial ecological relationships in the marine environment. Inorganic nitrogen can affect the type of relationship between algae a...
Impact of Bioaugmentation on the Bioremediation of Saline-Produced Waters Supplemented with Anaerobic Digestate
Bioremediation of produced waters has been widely investigated in the last decades. More recently, microalgae-based treatments have been developed to produce biomass. The objective of this study was to determine, at lab scale, the remediation efficiency of three origin of microorganisms: a consortium of three halotolerant and halophilic microalgae ...
Specifically adsorbed ferrous ions modulate interfacial affinity for high-rate ammonia electrosynthesis from nitrate in ...
Published in Proceedings of the National Academy of Sciences of the United States of America
The electrolysis of nitrate reduction to ammonia (NRA) is promising for obtaining value-added chemicals and mitigating environmental concerns. Recently, catalysts with high-performance ammonia synthesis from nitrate has been achieved under alkaline or acidic conditions. However, NRA in neutral solution still suffers from the low yield rate and sele...
