Bacterioplankton Activity in a Meso-eutrophic Subtropical Coastal Lagoon

Table 2

Bacterial growth rates (hour⁻¹ and day⁻¹) and coefficient of determination (R²), production rates (hour⁻¹ and day⁻¹) and coefficient of determination (R²), and doubling time for light, dark-control, and dark C + N + P treatments. Bacterial growth and production rates were determined from the slope of the linear regression of ln-transformed bacterial abundance or biomass versus time (from time zero to the end of the exponential growth phase).

Treatment	Growth rate (h^−1)	Growth rate (d^−1)	R^2	Production rate (h^−1)	Production rate (d^−1)	R^2	Doubling time
Light	0.026^b	0.626	0.86	0.018^b	0.437	0.98	1.106
Dark-control	0.033^b	0.789	0.74	0.021^a,b	0.500	0.62	0.878
Dark C + N + P	0.056^a	1.346	0.74	0.047^a	1.128	0.67	0.515
