Abstract

Microbes are the oldest, most abundant, and widespread form of life on Earth that have evolved and adapted to survive in diverse environments. Microbial diversity and their great importance are now widely recognized as they are key players in several ecosystem processes. However, many pathways, enzymes and molecular strategies employed by microbial assemblages to adapt and prosper in environments contaminated with one of humanity's most devastating sources of pollution, plastics, remain elusive. The goal here is to establish and investigate microbial-enriched plastic-degrading communities to understand microbial dynamics and to uncover novel enzymatic strategies for processing synthetic plastics-derived contaminants. We propose to employ an integrative approach combining ultra-deep time-resolved metagenomics and complementary omics as metatranscriptomics, metabolomics and single cell genomics, coupled with computational and data mining analyses to decipher microbes and microbial molecular strategies to allow their adaptation and processing of synthetic pollutants. As results, we expect to unveil unprecedented metabolic capabilities that ultimately may inspire the design and development of environmental-friendly routes to overcame urgent humanity challenges such as the over plastic pollution we face nowadays and thereby enhance carbon cycle dynamics.
