Degradative potential

In contrast, cells grown anaerobically with nitrate and vanillate were able to oxidize vanillate under both aerobic and anaerobic conditions. The cells were also able to demethylate a much wider spectrum of aromatic methoxy compounds under anaerobic conditions than under aerobic conditions (Taylor 1983). Such subtleties should be clearly appreciated and taken into consideration in evaluating the degradative potential of comparable organisms under different physiological conditions. 

In the second procedure, organisms with an established degradation potential for TCE were injected at the site.

Though extensive research has been recently reported in the open literature concerning biodegradation of azo-dyes, there is still a need for additional research. The close link between dye structure and reaction pathways and rates makes it difficult to extrapolate results obtained with one dye to that with others, even belonging to the same class. Dye-specific assessment of process rates and yields is therefore required. Also, the degradation potential of several bacteria or consortia active toward xenobiotics in dye degradation is far from being fully assessed. 

The studies with sediment cultures indicate natural degradation potential for aquatic sediments exposed to anthropogenic CP pollution. However, in situ remediation rates for CP-contaminated sediments may be difficult to enhance. Possibilities involve nutrient and electron donor/acceptor amendments. Ex situ remediation could involve sediment dredging and application of methods developed for soil decontamination, such as slurry reactors and composting. 

Enzymatic degradation of carbohydrates that form insoluble gels was approximately 50 times slower than degradation of polymers composed of the same monomer hnkages, but not forming gels (Alderkamp et al. 2007). If this difference is exemplary of the difference in degradation potential of free polymers and polymers embedded in a gel, turnover times may slow down from days to years.
