Dataset of elemental composition of LB Lennox (buffered) medium with and without glucose supplementation

But, the metals and metalloids concentrations of growth medium may be important for understanding the growth behaviour of microorganisms in the medium, as well as for purposes of quality control. This dataset reports the elemental concentrations of buffered LB Lennox medium with and without glucose supplementation detected by Agilent 7500a inductively coupled plasma mass spectrometry (ICP-MS) operated in hot plasma mode (1260 W).

Results revealed elevated concentrations of boron (31-40 ppm), magnesium (123-126 ppm), aluminium (15-19 ppm), calcium (101-140 ppm), chromium (19-23 ppm), manganese (227-285 ppm), iron-56 (196-255 ppm), iron-57 (896-945 ppm), nickel (2-3 ppm), and copper (45-46 ppm) in both glucose supplemented and unsupplemented LB Lennox (buffered) medium. Relatively high concentrations of chromium and copper may pose toxicity to microbial cells and affect their growth and biomass formation.
