Figure Lengend Snippet: A Serial dilution plating for growth on solid agar medium supplemented with rich (LB) or p -CA minimal medium. Abbreviated genotypes are indicated to the left of each image. B The native PP_0897 promoter was replaced with two different low abundance promoters and the impact on viability in rich medium or M9 p- CA minimal medium was quantified. C P. putida strains assayed for indigoidine production in M9 60 mM p -CA medium at the indicated time points following induction with 1.5% arabinose (w/v). Control is WT P. putida harboring genome integrated indigoidine pathway cassette and ∆PP_0897 is the single gene deletion strain. Strain D1b_gf ∆PP_0897 did not grow nor produced in M9 p- CA medium. D P. putida strains with promoter-varied PP_0897 expression assayed for indigoidine production. Specific indigoidine yield (mg/CFU) was calculated by normalizing the indigoidine with the number of total viable cells at 24 h. E P. putida strains with promoter-varied PP_0897 expression with or without induction of the indigoidine pathway in M9 60 mM p- CA, sampled at 24 h and 48 h for glutamate and indigoidine (Supplementary Fig. ). F , G Strains D1b_gf with or without ∆PP_0897 were transformed with an empty vector plasmid or a plasmid containing a P BAD -PP_0897 construct. F Growth in M9 60 mM p- CA medium with basal BAD promoter induction without inducer ( F ) or with 1.5% (w/v) arabinose ( G ) in 24 well microtiter dishes. Strain genotypes are indicated above each panel. Measurements are average of at least three independent replicates. Error bars represent mean ± S.D. ( n = 4) in ( C – E ). The shaded area represents mean ± S.D. ( n = 3) in ( F , G ).

Figure Lengend Snippet: A Overall workflow of the simulations performed to model the permissible flux space limiting growth coupled production. Proteomics data, the D1b_gf reduced model, and the iMAT algorithm are used to develop context-specific models, which are then used for sensitivity analysis. A double robustness analysis is applied to determine the tradeoff between growth represented as biomass formation flux, fumarase flux, and glutamine exchange reaction flux, removing glutamine from the system represented as glutamine flux. Double robustness analysis 3D plots of the genome-scale metabolic model (GSMM) of P. putida WT (iJN1462) ( B ), context-specific D1b_gf reduced model ( C ) and context-specific D1b_gf P PP_0415 -PP_0897 model (iMAT_PP_0415p_PP_0897) ( D ). A red box indicates the region of interest replotted in the detailed view. The units for fumarase and glutamine flux are mmol/gDCW/h, and the unit for biomass is h −1 . Infinity (Inf) represents unconstrained flux for the reaction and may have a variable value based on the definition of bounds for a GSMM.

Figure Lengend Snippet: A Model validation using BIOLOG TM phenotyping. Blue dots indicate each of the 190 metabolites tested (refer to Supplementary Table for details), and the light blue shaded region shows the accurately predicted metabolites, including 16 true positives and 75 true negatives. Red dots indicate the subset of metabolites that successfully rescued growth when fed both p -CA and l -malate. B Double robustness analysis on mixed carbon source utilization for growth and production. C – E Strains D1b_gf and D1b_gf ∆PP_0897 were fed three carbon sources, 50 mM p -CA, 100 mM malate, and 100 mM alanine. Samples were analyzed at the indicated time points for growth and metabolic profiles. C Optical density (OD 600 ) was monitored every 4 h. D Glutamate concentrations for strains D1b_gf and D1b_gf ∆PP_0897, intracellular and extracellular values pooled together. E Consumption profiles of the three carbon sources (malate, alanine, and p -CA) from the culture medium were monitored at the indicated time points using LC–MS. Error bars represent mean ± S.D.

Figure Lengend Snippet: Heat map of Phenotype MicroArray TM (PM) results for carbon and nitrogen source utilization by PAM 2766 T , R. equi DSM 20307 T and R. equi 103S (PAM 1126). Bacterial inocula were grown at 30°C in TSB until the stationary phase and then suspended in mReMM mineral medium and transferred to the PM plates. Incubabion was performed at 30°C with OD 590 monitored every 15 min for 48 hours in an OmniLog reader. Strains were tested in duplicate and results were analysed using OmniLog software. Maximum growth is represented in graded colours from lowest (black) to highest (yellow). Red arrows indicate differential utilization of a substrate between PAM 2766 T and R. equi. Black arrows in the PM1 and PM2A plates indicate a carbon source utilized by the three tested bacteria (see Table S2 for detailed results). Asterisks indicate false positive reactions in the PM2A plate previously reported in ref. .
