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

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. 4 conditions were analzyed with 3 biological replicates : total 12 samples
