library_construction_protocol: After each sample reached its desired A600 range, cells were centrifuged for 10 min. at 4,063 x g. The supernatant was removed and 1 mL of TRIzol (p/n: 15596026, Thermo) was added. The pellet was re-suspended by vortexing and the tubes were immediately frozen at -80°C. The cell pellets were later thawed, transferred to a Lysing Matrix B 2mL tube (p/n: 116911050, MPBio, Santa Ana, CA), and disrupted using a Mini-Beadbeater. The lysate was subjected to a chloroform organic extraction and followed by purification using RNeasy Mini Kit (p/n: 74104, Qiagen, Hilden, Germany). Quality checks and quantifications of the isolated RNA were carried out on the Agilent 2100 Bioanalyzer (Agilent Technologies, Santa Clara, CA). Ribosomal RNA was removed prior to library construction using Ribo-Zero rRNA Removal Kit Gram-Positive Bacteria (p/n: MRZGP126, Illumina). Stranded cDNA libraries were prepared using TruSeq Stranded mRNA Kit (p/n: 20020594, Illumina), quantitated by Agilent TapeStation, pooled quimolarly, and sequenced on one flowcell lane for 75 cycles using paired-end 75 basepair sequencing on Illumina 2500 HiSeq Rapid Cluster Kit v. 2 (p/n: PE-402-4002, Illumina) and HiSeq Rapid SBS Kit v. 2 (p/n: FC-402-4021, Illumina).
