The microarray analysis was performed with the Affymetrix P. aeruginosa GeneChip. Each condition was performed in triplicate, and each biological replicate was used for one GeneChip. In total, nine microarrays were used, which allowed changes in gene expression to be determined with a confidence value of P < 0.001. The data analyses were performed with applications belonging to the appropriate software packages from the Bioconductor microarray analysis suite59. The quality of all of the chips was assessed by fitting a linear model to the probe level data using the function fitPLM from the affyPLM package. The expression values were computed using the Robust Multichip Average algorithm60. The computations were performed using function “gc rma” from the package “affy”. The Rank Products algorithm was used to identify differentially expressed genes 61. A percentage of false positives (pfp) value of 0.05 was accepted. Protein mass spectrometric analysis. The samples were centrifuged for 1 min at 16,000 x g and 4°C. The supernatant was discarded, and the bacterial cell pellet was lysed in 1.2 ml of BugBuster® Protein Extraction Reagent (Novagen, Darmstadt, Germany) for 30 min at 4°C with further disruption by sonication (using a pin Sonicator® 3000; Misonix) for 2.5 min (10 watts) on ice (5 cycles x 0.5 min). The extracts were then centrifuged for 5 min at 12,000 x g to separate the cell debris and intact cells. Finally, the supernatants were carefully aspirated (to avoid disturbing the pellet) and transferred to a new tube. Protein digestion and tagging with iTRAQ-4-plex® reagent: The total protein concentration was determined using RC/DC protein assay (Bio-Rad, Madrid, Spain). For digestion, 20 μg of protein from each condition (UV+EVOH and UV-TiO2-coated EVOH) was precipitated by the methanol/chloroform method. Protein pellets were resuspended and denatured in 20 µl of 6 M guanidine hydrochloride/100 mM 4-(2-hydroxyethyl)piperazine-1ethanesulphonic acid (HEPES), pH 7.5, (SERVA Electrophoresis GmbH), reduced with 1 µl of 50 mM Tris(2-carboxyethyl) phosphine (TCEP, AB SCIEX, Foster City, CA, USA), pH 8.0, at 60°C for 30 min and then treated with 2 µl of 200 mM cysteine-blocking reagent (methyl methanethiosulphonate (MMTS; Pierce, IL, USA) for 10 min at room temperature. Samples were diluted up to 120 µl with 50 mM TEAB to reduce guanidine concentration. Digestions were initiated by adding 1.5 µl (1 µg/µl) sequence grade-modified trypsin (Sigma Chemical Co.; St. Louis, MO, USA) to each sample in a ratio 1/10 (w/w), which were then incubated at 37°C overnight on a shaker. The digested samples were evaporated to dryness. Each peptide solution was labelled at room temperature for 2 hours with a half unit of iTRAQ 2 Reagent Multi-plex kit (AB SCIEX, Foster City, CA, USA) that had been previously reconstituted with 80 μl of 70% ethanol/50 mM TEAB. In iTRAQ labelling, tags 114 and 115 were used to label UV+EVOH and UV-TiO2-coated EVOH condition, respectively. Afterwards, both labelled samples were combined and the labelling reaction was stopped by the addition of 100 µl of 50% acetonitrile (ACN) and evaporation in a Speed Vac. The digested, labelled and pooled peptide mixture was desalted using a Sep-PAK C18 Cartridge (Waters, MA, USA), the following manufacturer’s instructions. Lastly, the cleaned tryptic peptides were evaporated to dryness and stored at -20°C for further analysis. Liquid chromatography and mass spectrometer analysis: A 2.5-µg aliquot of the resulting mixture was subjected to 2D-nano LC ESI-MSMS analysis using a nano liquid chromatography system (Eksigent Technologies nanoLC Ultra 1D plus, AB SCIEX, Foster City, CA) coupled to high speed Triple TOF 5600 mass spectrometer (AB SCIEX, Foster City, CA) with a duo spray ionisation source. The analytical column used was a silica-based reversed phase column C18 ChromXP (75 µm × 15 cm) with a 3-µm particle size and a 120Å pore size (Eksigent Technologies, AB SCIEX, Foster City, CA). The trap column was a C18 ChromXP (Eksigent Technologies, AB SCIEX, Foster City, CA) with a 3-µm particle diameter and a 120-Å pore size, and it was switched on-line with the analytical column. The loading pump delivered a solution of 0.1% formic acid in water at 2 µl/min. The nano-pump provided a flow-rate of 300 nl/min and was operated under gradient elution conditions, using 0.1% formic acid in water as mobile phase A and 0.1% formic acid in ACN as mobile phase B. Gradient elution was performed according the following scheme: isocratic conditions of 98% A: 2% B for 1 minutes, a linear increase to 30% B in 210 minutes, a linear increase to 40% B in 10 minutes, a linear increase to 90% B in 5 minutes, isocratic conditions of 90% B for 5 minutes and a return to the initial conditions in 2 min. The injection volume was 5 µl. Data acquisition was performed with a TripleTOF 5600 System (AB SCIEX, Concord, ON). Data were acquired using an ion spray voltage floating (ISVF) 2800 V, curtain gas (CUR) 20, interface heater temperature (IHT) 150, ion source gas 1 (GS1) 20, declustering potential (DP) 85 V. All data were acquired using information-dependent acquisition (IDA) mode with Analyst TF 1.5 software (AB SCIEX, Foster City, CA, USA). For the IDA parameters, 0.25 s MS survey scan in the mass range of 350–1250 Da were followed by 15 MS/MS scans of 250 ms in the mass range of 100–1800 (total cycle time: 4.04 s). The switching criteria were set to ions with mass to charge ratio (m/z) greater than 350 and smaller than 1250 with a charge state of 2–5 and an abundance threshold of more than 90 counts (cps). Former target ions 3 were excluded for 20 s. IDA rolling collision energy (CE) parameters script was used for automatically controlling the CE. Data analysis: MS and MS/MS data obtained for pooled samples were processed using Analyst® TF 1.5.1 Software (AB SCIEX, Foster City, CA, USA). Raw data file conversion tools generated mgf files, which were also searched against a customised UniProtKB/SwissProt database from P. aeruginosa (taxonid:208964), containing 5,572 protein coding genes and their corresponding reversed entries using the Mascot Server v. 2.3.02 (Matrix Science, London, UK). Search parameters were set as follows: enzyme, trypsin; allowed missed cleavages, 1; fixed modifications, iTRAQ4plex (N-term and K) and beta-methylthiolation of cysteine; variable modifications, oxidation of methionine. The peptide mass tolerance was set to ± 20 ppm for precursors and 0.05 Da for fragment masses. The confidence interval for protein identification was set to ≥ 95% (p<0.05), and only peptides with an individual ion score above the 1% false discovery rate (FDR) threshold were considered correctly identified. Only proteins having at least two quantified peptides and pvalues of ≤ 0.1 were considered in the quantitation62. Metabolomic analysis by CE-TOF-MS. The samples were centrifuged for 1 min at 16,000 x g and 4°C, and the cell pellets immediately mixed with 1.2 ml of cold (-80ºC) HPLC-grade methanol (Sigma Chemical Co.; St. Louis, MO, USA). The samples were then stored at -80ºC for 60 min. Then, the samples were vortex-mixed (for 10 seg) and sonicated for 30 s (10 watts) on ice (5 cycles x 0.5 min). After sonication, the pellet was removed by centrifugation at 16,000 g for 20 min at 4ºC and the methanol solution was stored at -80ºC until use. Immediately, 1.2 ml milli-Q H2O was added to the cell pellet, and, after re-suspension, the samples were sonicated for 30 s (10 watts) on ice (5 cycles x 0.5 min). After sonication, the pellet was removed by centrifugation at 16,000 x g for 20 min at 4ºC and the water solution was separated. Finally, equal volumes (1 ml) of each of the methanol and H2O solutions were mixed and stored at -80ºC until analysis. The analysis was performed as follows: Samples for CE-MS analysis were prepared from a volume of 100 µl by evaporating to dryness using a Speedvac Concentrator (Thermo Fisher Scientific Inc., Waltham, MA). Each sample was then reconstituted in 100 µl of MilliQ® water with the internal standard (0.4 mM L-methionine sulphone) and 0.1 M formic acid. A capillary electrophoresis system (7100 Agilent) coupled with a TOF Mass Spectrometer (6224 Agilent) was employed for the CE-MS analysis of the samples. The CE mode was controlled by ChemStation software (B.04.03, Agilent) and MS mode by Mass Hunter Workstation Data Analysis (B.02.01, Agilent). The separation occurred 4 in a fused-silica capillary (Agilent) (total length, 100 cm; i.d., 50 μm). All separations were carried out in normal polarity with a background electrolyte containing a 0.8 M formic acid solution in 10% methanol (v/v) at 20ºC. New capillaries were pre-conditioned with a flush of 1.0 M NaOH for 30 min followed by MilliQ® water for 30 min and background electrolyte for 30 min. Before each analysis, the capillary was conditioned with a flush of background electrolyte for 5 min. The sheath liquid (6 µl/min) was MeOH:H2O (1:1) containing 1.0 mM formic acid with two reference masses: m/z 121.0509 ([C5H4N4+H]+) and m/z 922.0098 ([C18H18O6N3P3F24+H]+), which allowed correction and higher mass accuracy in the MS. The samples were hydrodynamically injected at 50 mBar for 50 s. The stacking was carried out by applying background electrolytes at 100 mBar for 20 s. The separation voltage was 30 kV, the internal pressure was 25 mBar and the analyses were carried out for 35 min. The MS parameters were as follows: fragmentor, 100 V; skimmer, 65 V; octopole, 750 V; drying gas temperature, 200 ºC; flow rate, 10 l/min; and capillary voltage, 3500 V. The data were acquired in positive mode with a full scan from m/z 85 to 1000 at a rate of 1.41 scan/s. The resulting data files were cleaned of background noise and unrelated ions by Mass Hunter Qualitative Analysis software (B.05.00, Agilent). This tool was used to look for the target list of the compounds (±20 ppm) that were interesting for the project in the corresponding electropherograms. The identity of each compound was confirmed in a second analysis by adding the corresponding standard (10 ppm) to the samples. Then, each sample was checked for an increase in the peak; the result was positive in all cases. The following reagents have been used for the metabolomic analysis: formic acid (MS grade - Sigma-Aldrich, Steinheim, Germany), L-methionine sulphone (Sigma-Aldrich, Taufkirchen, Germany), sodium hydroxide (Panreac-Montcada I Reixac, Spain), and the reference masses were purine and hexakis (1H,1H,3H-tetrafluoropropoxy)phosphazine (HP)) from Agilent (API-TOF reference mass solution kit). All solutions were prepared using MilliQ® water (Millipore, Billerica, MA, USA). Supplementray references 59. Gentleman, R. C. et al.
