Evaluation of Edaphic Microbial Ammonium Oxidizing Communities during a Yellow Potato Cycle Culture

Project description:This study evaluated the ammonium oxidizing communities (COA) associated with a potato crop (Solanum phureja) rhizosphere soil in the savannah of Bogotá (Colombia) by examining the presence and abundance of amoA enzyme genes and transcripts by qPCR and next-generation sequence analysis. amoA gene abundance could not be quantified by qPCR due to problems inherent in the primers; however, the melting curve analysis detected increased fluorescence for Bacterial communities but not for Archaeal communities. Transcriptome analysis by next-generation sequencing revealed that the majority of reads mapped to ammonium-oxidizing Archaea, suggesting that this activity is primarily governed by the microbial group of the Crenarchaeota phylum. In contrast,a lower number of reads mapped to ammonia-oxidizing bacteria.

Transcriptome data of Alcaligenes sp. HO-1 in response to ammonium stimulation at several time points.

Project description:A heterotrophic ammonia-oxidizing bacterium Alcaligenes sp. HO-1 was isolated from the activated sludge of a bioreactor treating ammonia-rich piggery wastewater. The goal and objectives of this experiment are to analyze the transcriptome profiles of nitrogen-metabolism-related genes of Alcaligenes sp. HO-1 in response to ammonium stimulation over time and to find out potential genes involved in ammonia oxidation process. So the RNA-seq anaylsis was performed by setting up each time points (0, 3.5, 10, 22 hours) when strain HO-1 were exposed to ammonia. HO-1 was cultured with 83 mM succinate and 14 mM ammonium sulfate until ammonia was completely consumed and then another 14 mM of ammonium sulfate was added to the culture. Cells were harvested at 0 h, 3.5 h, 10 h and 22 h after the addition of ammonium sulfate. The sequencing data of RNAs obtained from strain HO-1 cells at each time was analyzed.

Differential contribution of nitrifying prokaryotes to nitrification in groundwater

Project description:The ecophysiology of complete ammonia oxidizing Nitrospira (CMX) and their widespread occurrence in groundwater suggests that CMX bacteria have a competitive advantage over ammonia-oxidizing bacteria (AOB) and archaea (AOA) in these environments. However, the relevance of their activity from the ecosystem-level process perspective has remained unclear. We investigated oligotrophic carbonate rock aquifers as a model system to assess the contribution of CMX, AOA and AOB to nitrification and to identify the environmental drivers of their niche differentiation at different levels of ammonium and oxygen. CMX accounted for up to 95% of the ammonia oxidizer communities. Nitrification rates were positively correlated to CMX clade A-associated phylotypes and AOB affiliated with Nitrosomonas ureae. Surprisingly, short-term incubations amended with the nitrification inhibitors allylthiourea and chlorate suggested that AOB contributed more than 90% to overall ammonia oxidation, while metaproteomics analysis confirmed an active role of CMX in both ammonia and nitrite oxidation. Ecophysiological niche differentiation of CMX clades A and B, AOA and AOB was linked to their requirements for ammonium, oxygen tolerance, and metabolic versatility. Our results demonstrate that despite numerical predominance of CMX, the first step of nitrification in oligotrophic groundwater is primarily governed by AOB. Higher growth yields at lower NH4+ turnover rates and energy derived from nitrite oxidation most likely enable CMX to maintain consistently high populations. Activity measurements combined with differential inhibition allowed a refined understanding of ammonia oxidizer coexistence, competition and cooperation beyond the insights from molecular data alone.
