Exploring microbial consortia from various environments for plastic degradation.

ABSTRACT

Many complex natural and synthetic compounds are degraded by microbial assemblages rather than single strains, due to usually limited metabolic capacities of single organisms. It can therefore be assumed that plastics can be more efficiently degraded by microbial consortia, although this field has not been as widely explored as plastic degradation by individual strains. In this chapter, we present some of the current studies on this topic and methods to enrich and cultivate plastic-degrading microbial consortia from aquatic and terrestrial ecosystems, including substrate preparation and biodegradation assessment. We focus on both conventional and biodegradable plastics as potential growth substrates. Cultivation methods for both aerobic and anaerobic microorganisms are presented.
