TABLE 2.
The estimated activation energy (Ea in eV) and temperature coefficient, Q10, for bioavailable dissolved carbon (BDOC), bacterial growth (BG), productivity (BPInt), cell-specific bacterial production (Cell BP), alkaline phosphatase (APaseInt), β-glucosidase (BGaseInt), and leucine aminopeptidase (LAPaseInt) enzymatic activity integrated over the 4 days incubation period in the different experiments (control, glucose, seagrass, and mangrove). Average values ± standard errors.
