Abstract

Bioaugmentation represents a remarkable success story of applied research, and future research should lead to more successful applications. This chapter provides an introduction to the future potential of bioaugmentation (and bioremediation in general), and seeks to identify the research needs that, if addressed, will help realize this potential. First, a discussion of bioremediation at the molecular, organismal, community and ecosystem scales is presented. Cultivating a deeper understanding and/or developing new techniques at any of these levels may lead to advances and novel discoveries, and some future initiatives are suggested. Three linchpin concepts that will likely direct the future of bioremediation are examined in detail: niche specialization as a means to enhance bioremediation specificity; microcosms as valuable tools for directed research; and the enrichment paradox, which enacts a balance between research ideals, regulatory requirements and remediation activities. From these three concepts, an optimal scenario for successful bioremediation is proposed. Some practical applied research needs are outlined, and finally, future perspectives are described. While not presently feasible or in practice, these ideas give hints as to what may eventually be possible within the field of bioremediation.
