Figure 5From: Methodological approaches to help unravel the intracellular metabolome of Bacillus subtilisCell leakage during liquid nitrogen cooling. Relative amount (related to the integral of the internal standard ribitol) of extracellular metabolites in the supernatant after direct sterile filtration compared to those in the supernatant after liquid nitrogen cooling. Light grey: direct filtration, and dark grey: after liquid nitrogen cooling.Back to article page
