Relevant indicators of guanosine production by engineered B. subtilis strains.
a Guanosine production. b Guanosine yield. c Biomass. d Transcriptional expression levels of relevant genes in strains BSK756G2, BSK814G2 and BSF1G2. The strains were cultivated in 100 ml LBG medium at 37 °C under constant orbital shaking at 220 rpm. Biomass yields were measured at 28 h
