“…Furthermore, marine cyanobacteria like Microcoleus chthonoplastes, Phormidium corium, and A. quadruplicatum can remove phenanthrene [161]. Another Phormidium species from coastal environments in Todoa Santos Bay, Mexico, effectively removed 45% of hexadecane and 37% of diesel oil from seawater in 10 days [162]. Additionally, Isochrysis galbana and Nannochloropsis oculata are promising candidates for eliminating hydrocarbons from contaminated seawater, achieving an impressive 80% removal rate [163].…”

In an era of rising population density and industrialization, the environment confronts growing challenges. Soil, agricultural land, and water bodies are becoming increasingly polluted by petroleum waste and hydrocarbons. While hydrocarbons are naturally present in crude oil, refining processes compound the complexity and toxicity of hydrocarbons. This is particularly evident in polycyclic aromatic hydrocarbons (PAHs) found in the air and soil, known for their carcinogenic, mutagenic, and teratogenic properties. In response, biodegradation emerges as an eco-friendly, cost-effective solution, especially in petroleum-contaminated settings. Biodiverse microbial communities play a pivotal role in managing hydrocarbon contamination, contingent on location, toxicity, and microbial activity. To optimize biodegradation, understanding its mechanisms is essential. This review delves into varied bioremediation techniques, degradation pathways, and the contributions of microbial activities to efficiently removing hydrocarbon pollutants. Recent research spotlights specific microorganisms like bacteria, microalgae, and fungi adept at hydrocarbon degradation, offering a contemporary perspective on petroleum hydrocarbon pollutant bioremediation. These microorganisms efficiently break down petroleum hydrocarbons, with enzymatic catalysis markedly accelerating pollutant breakdown compared to conventional methods. Given the intricate nature of hydrocarbon contamination, cooperative bacterial consortia are instrumental in effective cleanup, driven by specific genes guiding bacterial metabolism. For cost-effective and efficient removal from compromised environments, it is advisable to adopt an integrated approach that combines biostimulation and bioaugmentation.

“…To this aim, marine cyanobacteria A. quadruplicatum , Microcoleus Chthonoplastes , and Phormidium corium have been reported as capable of removing phenanthrene [ 161 ]. Another marine taxon belonging to the genus Phormidium , isolated from microalgal mats of coastal environments of Todoa Santos Bay (Mexico), was effective for hydrocarbon removal, being able to remove about 45% and 37% of hexadecane and diesel oil from seawater within 10 days, respectively [ 162 ]. Moreover, Nannochloropsis oculata (eustitgmatophyte) and Isochrysis galbana (haptophyte) have been described as promising candidates for the removal of hydrocarbons from contaminated seawater (removal yield of about 80% [ 163 ]).…”

Bacteria, Fungi and Microalgae for the Bioremediation of Marine Sediments Contaminated by Petroleum Hydrocarbons in the Omics Era

Petroleum hydrocarbons (PHCs) are one of the most widespread and heterogeneous organic contaminants affecting marine ecosystems. The contamination of marine sediments or coastal areas by PHCs represents a major threat for the ecosystem and human health, calling for urgent, effective, and sustainable remediation solutions. Aside from some physical and chemical treatments that have been established over the years for marine sediment reclamation, bioremediation approaches based on the use of microorganisms are gaining increasing attention for their eco-compatibility, and lower costs. In this work, we review current knowledge concerning the bioremediation of PHCs in marine systems, presenting a synthesis of the most effective microbial taxa (i.e., bacteria, fungi, and microalgae) identified so far for hydrocarbon removal. We also discuss the challenges offered by innovative molecular approaches for the design of effective reclamation strategies based on these three microbial components of marine sediments contaminated by hydrocarbons.
