Iron oxidation model template pathway. Bolded reactions (rxn60857, rxn60858, rxn60859, rxn13689) represent those added to the ModelSEED biochemistry database by this template. Created with BioRender.com.

In #MRAJournal: a KBase tutorial narrative demonstrating construction of stoichiometric metabolic models of iron-oxidizing bacteria, enabling predictions of physiological dynamics, metabolic fluxes and the role of iron oxidation in environmental systems. asm.social/2MW

Functional categories of genes for which interruption significantly alters Mtb fitness during acid growth. Pie charts representing the total hits (= 95) comprising 21 over-represented and 74 under-represented hits sorted by functional categories (color coding, see legend).

Adaptation of M. tuberculosis to acidic niches within the host is vital to establish the disease. In #MRAJournal, researchers present a high-density transposon mutant sequencing library data set identifying genetic determinants of acid growth arrest. asm.social/2vL

Expected and sequenced relative abundances for the (A) 16S even, (B) 16S staggered, (C) 18S even, and (D) 18S staggered mock communites. 16S taxonomy is from Parada et al. (4), and 18S taxonomy is from the PR2 database (13). Expected relative abundances are shown as ratios in the recipe spreadsheets included in the accompanying protocol.

Mock communities are needed to ensure that sequencing runs have an acceptable bias. In #MRAJournal: marine microbial mock communities for validating rRNA gene amplicon sequencing, enabling detection of biased or aberrant runs. Read the article: asm.social/2sr
