In order to describe the transformations of tannic acid during its degradation (under aerobic and anaerobic conditions) incubations were performed. To evaluate the oxygen consumption, the tannic acid was added to 1 L of water sample from Monjolinho's reservoir (22º00'S and 47º54'W); these solutions were aerated and the dissolved oxygen was monitored for 16 days, the anaerobic process was avoided. For the anaerobic and aerobic degradation, the dissolved organic carbon and the acid tannic concentrations were estimated on the samples days. The results were fitted to first-order kinetic model, being possible to verify that during the 16 days the oxygen uptake was 3.6 mg.L-1, the deoxygenation rate (kD)of this process was 0.39 day-1. The degradation coefficients were calculated through the decay of the tannic acid and organic carbon concentrations. In the aerobic process, the global decay coefficient (kG) was 0.36 day-1 and in the anaerobic 0.28 day-1. Overall, the obtained degradation coefficients suggest that the bacterioplankton of the Monjolinho's reservoir possess a high capacity of polyphenols degradation.

Tetrabromobisphenol-A (TBBPA) is a pollutant which has a devastating impact on our environment and should be removed from earth. This research aims to evaluate the aerobic and anaerobic TBBPA degradation and bacterial community changes in mangrove sediments. TBBPA degradation in the sediments was enhanced with a microcapsuled enzyme extract of spent mushroom compost (MC) under aerobic conditions and with zerovalent iron under anaerobic conditions. The TBBPA aerobic or anaerobic degradation rates were enhanced for three time additions. Four bacterial genera (Bacillus, Erythrobacter, Pseudomonas, Rhodococcus) were associated with TBBPA aerobic degradation; and four other bacterial genera (Desulfovibrio, Pseudomonas, Sphaerochaeta, Sphingomonas) were associated with TBBPA anaerobic degradation in the sediment. Moreover, nine methanogens were identified under anaerobic conditions that might also be involved in TBBPA anaerobic degradation in the sediment. Our results demonstrate two feasible methods toward TBBPA bioremediation for mangrove sediments under aerobic and anaerobic conditions.
