contaminated site, to induce growth of microorganisms whose enzymes can degrade both the co-substrate and the original pollutant. Even inherently toxic inducers, such as phenol or toluene, are sometimes added to stimulate bacterial production of enzymes to degrade polyaromatic hydrocarbons and chlorinated aliphatics.

Table 11.17.2 lists important treatment data needs for biological treatments.

This section describes biological processes applicable to hazardous waste.
