“…However, nature has provided us with a remarkable solution in the form of bacterial degradation of alkanes. Bacteria have evolved the ability to utilize petroleum hydrocarbons as a carbon and energy source, playing a crucial role in mitigating the environmental impact of oil spills and petroleum pollution (Adetunji et al, 2021). This review aims to explore the ecological implications of bacterial degradation of alkanes in petroleum-contaminated environments.…”

This review explores the ecological implications of bacterial degradation of alkanes in petroleum-contaminated environments, with a focus on microbial community dynamics and functional interactions. The complex interplay between alkane-degrading bacteria and other microorganisms shapes the fate and behavior of petroleum hydrocarbons, influencing ecosystem functioning and stability. The microbial community structure in petroleum-contaminated environments is characterized by a diverse assemblage of alkane-degrading bacteria (Such as Pseudomonas sp., Alcaligenes sp., Bacillus sp., Acinetobacter sp). These bacteria exhibit varying abilities to degrade different hydrocarbon fractions, leading to distinct patterns in community composition. Factors such as hydrocarbon concentration, environmental conditions, and the presence of co-contaminants influence the abundance and distribution of alkane-degrading taxa, shaping the microbial community dynamics. Functional interactions among alkane-degrading bacteria are essential for efficient degradation processes. Synergistic interactions and metabolic cooperation between different microbial species enhance the degradation capabilities of the community as a whole. Co-metabolism and cross-feeding relationships among bacteria enable the degradation of complex hydrocarbon mixtures. Furthermore, non-degrading microorganisms contribute to the overall alkane degradation process by providing essential metabolic intermediates or modulating environmental conditions. The presence of alkane-degrading bacteria affects the diversity and abundance of other microbial communities, leading to cascading effects on the broader ecosystem. Molecular tools, such as high-throughput sequencing and metagenomics, have advanced our understanding of microbial community structure and function. This review provides valuable insights into the ecological implications of bacterial degradation of alkanes in petroleum-contaminated environments. It highlights the importance of microbial community dynamics and functional interactions in shaping the fate of petroleum hydrocarbons and emphasizes the potential of harnessing these interactions for effective bioremediation strategies. Further research is needed to unravel the complex ecological networks involved in alkane degradation and to develop innovative approaches for sustainable environmental management.
