Anammox bacteria can metabolize short-chain fatty acids, but their role in carbon utilization during mixotrophic processes is not fully understood.
This study used advanced techniques like genome-resolved metagenomics and DNA stable isotope probing to analyze an Anammox process with acetate.
Researchers identified essential genes related to acetate metabolism and noted that "Candidatus Jettenia caeni" played a significant role in carbon utilization, emphasizing its importance in treating wastewater with low organic matter and ammonia.
Production of wood-based activated carbon (WAC) generates large volume of highly acidic and phosphate-rich wastewater. Currently, the routine treatment (i.e.
Obligate aerobic methanotrophs can oxidize methane and participate in denitrification under low oxygen conditions, but the specifics of this process in aerobic methane oxidation (AME-D) remain underexplored.
A methanotrophic consortium was cultivated in a specialized bioreactor, achieving a significant nitrite removal rate of about 50 mg N/L/d.
Metagenomics techniques identified Methylomonas as the key player in methane oxidation and partial denitrification, revealing important genes related to nitrogen reduction processes and suggesting a possible connection between methanotrophy and denitrification.
