| Organism |
Bacillus subtilis subsp. subtilis str. 168 |
| Characteristics |
genotype: prsA-je1
experimental group: control
|
| Growth protocol |
B. subtilis strain 168 ΔspoIIAC ΔamyE Δapr ΔnprE ΔsrfAC was maintained on LBPG medium at room temperature and not placed at 4 C. Two different substrains were generated, one with a codon-optimized α-amylase JE1 sequence (prsA+je1zyn), and one with the wild-type sequence (prsA+je1). The genomic sequences for both substrains were retrieved in a separate experiment by Novozymes A/S. If not indicated otherwise, strains were cultivated at 37 C in erythromycin (1 µg/ml)-supplemented triptone-yeast (TY) medium when appropriate. The bacterial enzyme production fermentations were conducted in duplicates in custom Novozymes made 5L tanks.

| Extracted molecule |
total RNA |
| Extraction protocol |
Samples were harvested by mixing 5 ml cell culture with 5 ml 100% ethanol, immediately storing on dry ice before transferring to -80°C. RNA was isolated using phenol-chloroform extraction.
Bacterial RNA library preparation was prepared from rRNA-depleted total RNA as described in https://doi.org/10.1002/cpnc.55
Single-end sequencing on an Illumina NextSeq 500. The read lengths were 76 bp.
