Abstract
ABSTRACTWe report here the metagenomes and metatranscriptomes of activated sludge bioreactors, enriched or not enriched with aerobic granules, at an initial state and after 1 month of incubation. Data showed that the added granular biomass expressed higher levels of expression of genes involved in ammonia elimination.

After the addition of 1 liter of a mixture made of wet oxidation effluent, leachate, and water, the granulation process of the activated sludge (AS) was followed in both bioreactors for 1 month, with a four-step cycle, repeated every 3 days and pH values maintained between 6 and 8 throughout the experiment
Summary
We report here the metagenomes and metatranscriptomes of activated sludge bioreactors, enriched or not enriched with aerobic granules, at an initial state and after 1 month of incubation. Data showed that the added granular biomass expressed higher levels of expression of genes involved in ammonia elimination. The anaerobic digestion is commonly used for reducing sludge solids in wastewater treatment and can be improved by the wet oxidation process (WOX), which aims to convert carbon into methane through oxidation of organic compounds.
