Effect of microbial growth rate on temperature and metabolic water recorded in 18O/16O ratios of PO4 in DNA

It has been recently demonstrated that both temperature and intracellular/metabolic water are recorded by the PO4 moieties comprising the backbone of DNA in microbial cells as well as in total microbial biomass PO4 (Blake et al., 2016; Li et al., 2016). Temperature and intracellular water composition are reflected in the 18O/16O ratio of PO4 (δ18OP) in DNA (Blake et al., 2016). To determine whether the reported temperature recording by microbial...
