Biodegradation of 3 different biological materials (trichodesmium erythraeum, Lucifer and mixed plankton) was studied to estimate their rate and extent of decomposition in surface sea water under controlled laboratory conditions. Rate of decomposition during the first 20 days was approximated by the 1st order Kinetics. Rate constants for the degradation suggested that there were 3 stages in the microbial decomposition and that 2 labile organic fractions and a refractory organic fraction could be identified. Approximately, 15-20% of the initial dissolved organic matter (DOM; fraction F1) was oxidized. The other labile fraction F2 was about 30-45% of the total DOM. The refractory portion was about 40% and it was resistant to biological oxidation. Rate constant for F1 of T. erythraeum was 0.0331 day-1 and of Lucifer was 0.0723 day-1 and for mixed plankton, it was 0.1188 day-1. |
