ABSTRACTWe announce the draft genome sequences of 12Bacteroides, 4Phocaeicola, and 2Parabacteroidesstrains, among which was a newly isolated species,Bacteroidaceaebacterium UO.H1004. These isolates produce health-benefiting short-chain fatty acids (SCFAs) and the neurotransmitter γ-aminobutyric acid (GABA) in various concentrations.
