Project description:Although the biodegradation of biodegradable plastics in soil and compost is well-studied, there is little knowledge on the metabolic mechanisms of synthetic polymers degradation by marine microorganisms. Here, we present a multiomics study to elucidate the biodegradation mechanism of a commercial aromatic-aliphatic copolyester film by a marine microbial enrichment culture. The plastic film and each monomer can be used as sole carbon source. Our analysis showed that the consortium synergistically degrades the polymer, different degradation steps being performed by different members of the community. Analysis of gene expression and translation profiles revealed that the relevant degradation processes in the marine consortium are closely related to poly(ethylene terephthalate) biodegradation from terrestrial microbes. Although there are multiple genes and organisms with the potential to perform a degradation step, only a few of these are active during biodegradation. Our results elucidate the potential of marine microorganisms to mineralize biodegradable plastic polymers and describe the mechanisms of labor division within the community to get maximum energetic yield from a complex synthetic substrate.

Project description:In the present study, we were interested in gene expression changes in the pectoralis muscle of juvenile king penguins during the transition from terrestrial to marine life. Strictly terrestrial during their first year after hatching, king penguin chicks must then depart to sea to reach nutritional emancipation and pectoralis muscle is largely involved in penguin adaptation to the marine environment. To compare these transcriptomic profiles, we realized heterologous hybridization on Affymetrix GeneChip Chicken Genome Arrays, as the chicken is the closest model species for which microarrays are available. The development of a new algorithm, MaxRS, allow us to determine differentially expressed genes implicated in energetic metabolism or involved in cellular defense against reactive oxygen species and associated injuries. We compared muscle sample biopsy from 4 penguin juveniles captured just before they undergone their first immersion to cold water (named NI for Never Immersed) and 3 penguin juveniles that had completly accomplished their acclimation to marine life (named SA for Sea Acclimated).

Project description:Marine is one of the most important resources of microorganisms, including bacteria, actinomycetes, and fungi. As marine and terrestrial environments differ a lot in many aspects it is not surprising that the species and characteristics of microorganisms living there are very different. Interestingly, many marine microorganisms can find their congeners of the same species from terrestrial resources. The aim of this work is to evaluate the intraspecies differences between marine and terrestrial actinomycetes on metabolic level and to uncover the mechanism responsible for the differences. To address this, we carried out comparative metabolomics study on Nesterenkonia flava strains isolated from marine and terrestrial environments. The results showed that marine strains were clearly distinguished from their terrestrial congeners on the principal components analysis (PCA) scores plot of intracellular metabolites. The markers responsible for the discrimination of marine and terrestrial strains were figured out using loading plot from partial least squares discrimination analysis (PLS-DA). Pathway analysis based on PLS-DA, univariate analysis, and correlation analysis of metabolites showed that the major differential metabolites between the terrestrial N. flava and the marine ones were involved in osmotic regulation, redox balancing, and energy metabolism. Together, these insights provide clues as to how the previous living environment of microbes affect their current metabolic performances under laboratory cultivation conditions.

Project description:The diversity and environmental distribution of the nosZ gene, which encodes the enzyme responsible for the consumption of nitrous oxide, was investigated in marine and terrestrial environments using a functional gene microarray. The microbial communities represented by the nosZ gene probes showed strong biogeographical separation, with communities from surface ocean waters and agricultural soils significantly different from each other and from those in oceanic oxygen minimum zones. Atypical nosZ genes, usually associated with incomplete denitrification pathways, were detected in all the environments, including surface ocean waters. The abundance of nosZ genes, as estimated by quantitative PCR, was highest in the agricultural soils and lowest in surface ocean waters.
