This Narrative is part of a collection used in a single publication. The paper took a metagnomic and metatranscriptomic approach to examine a bioreactor's response to the presence of sulfate, which reduces the production of methane, a valuable product, while producing hydrogen sulfide, a corrosive contaminant.
This Narrative collection has been created to highlight the types of analyses done for this publication. They are as follows (in order):

The binned contigs were extracted as MAG assemblies using Extract Bins as Assemblies from BinnedContigs, and then an AssemblySet was generated to group the MAGs.

Resulting annotated assemblies (genome objects in KBase) were combined into a genome set, and domain annotation was performed on the resulting set.
Then, the annotated genome set was placed into a species tree.
