The biological availability of contaminating and naturally occurring organic compounds can be estimated by finding their solubility in water. The more soluble the compound, the more available it is for decomposition. While this is true for most organic compounds, there are some that are soluble but also recalcitrant to decomposition. This is the result of complex, sometimes multi-cyclic, structures that inhibit decomposition, such as those of polysaccharides and lignins [2],... 

In Figure 2 the further reactions of the lignin decomposition products, which involve biological oxidation in the soil or in cultures or microorganisms, are summarized. All of the secondary reaction products could be identified.
