Natural Hydrocarbon-Contaminated Springs as a Reservoir of Microorganisms Useful for Bioremediation: Isolation and Multilevel Analysis of Hydrocarbonoclastic Bacteria from the Agri Valley (Southern Italy)

Sustainability, Journal Year: 2025, Volume and Issue: 17(7), P. 3083 - 3083

Published: March 31, 2025

This research aimed to characterise hydrocarbonoclastic bacteria isolated from naturally hydrocarbon-contaminated springs and the surrounding soils in Agri Valley (Southern Italy) assess effectiveness of bioaugmentation using a four-strain microbial consortium for removing hydrocarbons artificially diesel-contaminated lake waters mesocosm experiments. Four novel bacterial strains were selected experimentation: Gordonia amicalis S2S5, Rhodococcus erythropolis S2W2, Acinetobacter tibetensis S2S8, puyangensis S1W1. The four isolates can use diesel oil as their sole carbon source, some exhibited relatively high emulsifying capacity ability adhere hydrocarbons. Furthermore, genome analyses revealed presence genes associated with degradation, detoxification, transport various contaminants. Mesocosm experiments demonstrated that enhanced capacities native communities remove hydrocarbons, although drastic changes composition (analysed through Next-Generation Sequencing—NGS) observed. Taken together, these results suggest contaminated environments serve valuable reservoir microorganisms significant biotechnological potential, particularly field bioremediation. However, complete understanding efficiently degrade contaminants requires further fully capabilities limitations across different settings.

Ecological Shifts and Functional Adaptations of Soil Microbial Communities Under Petroleum Hydrocarbon Contamination

Water, Journal Year: 2025, Volume and Issue: 17(8), P. 1216 - 1216

Published: April 18, 2025

Petroleum hydrocarbon contamination has emerged as a significant global environmental issue, severely impacting soil microbial communities and their functions. This study employed high-throughput sequencing to systematically analyze the bacterial community structure functional genes in soils with varying levels of petroleum contamination. The results demonstrated that led decline diversity, while enhancing abundance specific genes, such those involved polycyclic aromatic (PAH) degradation, methane production, denitrification. Phylogenetic analysis further revealed highly contaminated tended form clustered specialized groups, simultaneously promoting coexistence phylogenetically distant microorganisms. Mantel test identified correlations between ammonium ion concentration, moisture content, metabolic pathways, particularly related degradation These findings suggest not only disrupts carbon nitrogen metabolism balance but also profound implications for greenhouse gas emissions cycling, potentially destabilizing ecosystem. provides novel insights into ecological functions petroleum-contaminated highlights potential key factors pollution management restoration.
