Microbial strategies driving low concentration substrate degradation for sustainable remediation solutions

npj Clean Water, Journal Year: 2024, Volume and Issue: 7(1)

Published: June 25, 2024

Abstract Microbial metabolism upholds a fundamental role in the sustainability of water ecosystems. However, how microorganisms surviving low-concentration substrate environments, including existence emerging compounds interest, remains unclear. In this review, microbial strategies for concentrating, utilizing, and metabolizing low concentration substrates were summarized. Microorganisms develop substrate-concentrating at both cell aggregate levels substrate-limited settings. Following, uptake transport are facilitated by adjusting physiological characteristics shifting affinities. Finally, metabolic pathways, such as mixed-substrate utilization, syntrophic metabolism, dynamic response to nutrient variation, population density-based mechanisms allow efficiently utilize adapt challenging oligotrophic environments. All these will underpin devising new approaches tackle environmental challenges drive ecosystems, particularly managing contaminants (i.e., micropollutants).

Exometabolomic exploration of culturable airborne microorganisms from an urban atmosphere

Atmospheric chemistry and physics, Journal Year: 2025, Volume and Issue: 25(3), P. 1805 - 1829

Published: Feb. 10, 2025

Abstract. The interactions of metabolically active atmospheric microorganisms with cloud organic matter can alter the carbon cycle. Upon deposition, influence microbial communities in surface Earth systems. However, metabolic activities cultivable settled habitats remain less understood. Here, we cultured typical bacterial and fungal species isolated from urban atmosphere using tryptic soy broth (TSB) Sabouraud dextrose (SDB), respectively, investigated their exometabolites to elucidate potential roles biogeochemical cycles. Molecular compositions were analyzed ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry. Annotation through Kyoto Encyclopedia Genes Genomes database helped identify processes. Results showed that strains produced lower H / C higher O ratios compared both consumed resistant compounds. As CHON compounds are abundant TSB (85 %) SDB (78 %), also constituted over 50 % identified exometabolite formulas. Bacterial more CHONS (25.2 while rich CHO (31.7 %). These predominantly comprised aliphatic/peptide-like carboxyl-rich alicyclic molecule (CRAM)-like Significant variations metabolites observed among different strains.
