DT values are the geometric means ± standard deviations of the log concentrations of RNA/g of DT determined on the basis of three separate extractions (each analyzed in triplicate), except for two values based on one extraction (indicated by an asterisk [*]) whose results were compromised due to technical problems (extraction failure and lack of DT). The percent extraction efficiency coefficient (Ext. ef.) represents the average value from the 6 extractions. LQ, limit of quantification.
