“…In addition, several SRPs, assigned to Deltaproteobacteria, Firmicutes, Nitrospira, Thermodesulfobacteria, Euryarchaeota, and Crenarchaeota, have been reported in oil reservoirs (Varjani and Gnansounou, 2017). Among them, thermophilic SRPs Desulfotomaculum, Desulfonauticus, Thermodesulforhabdus, Thermodesulfobacterium, Thermodesulfovibrio, and Archaeoglobus were more represented in high-temperature reservoirs (Singh and Choudhary, 2021;Zhou et al, 2023). In our sulfate-amended culture, Archaeoglobus was the most abundant, followed by other SRPs belonging to the candidate family Nap2-2B and Thermodesulfovibrio.…”

“…Genes involved in anaerobic hydrocarbon degradation were searched against a previously curated database using BlastP (e-value, 1e-10; identity, 30%) (Dong et al, 2019). Hydrogenases were identified by DIAMOND BlastP via a comparison with HydDB (e-value, 1e-50; qcover, 90%; identity, 50%) (Ju and Zhang, 2015;SøNdergaard et al, 2016).…”

“…They can utilize hydrocarbons, volatile fatty acids (VFAs), and H 2 while reducing sulfate to produce sulfide. This process contributes to reservoir corrosion and souring, increased refining costs, and health risks (Li et al, 2017;Vigneron et al, 2017;Singh and Choudhary, 2021). Although there have been studies on the diversity and distribution of SRPs in oil reservoirs (Guan et al, 2013;Fan et al, 2017), information on the interactions between SRPs and other community members during petroleum degradation is still limited.…”

While pressure is a significant characteristic of petroleum reservoirs, it is often overlooked in laboratory studies. To clarify the composition and metabolic properties of microbial communities under high-pressure conditions, we established methanogenic and sulfate-reducing enrichment cultures under high-pressure conditions using production water from the Jilin Oilfield in China. We utilized a metagenomics approach to analyze the microbial community after a 90-day incubation period. Under methanogenic conditions, Firmicutes, Deferribacteres, Ignavibacteriae, Thermotogae, and Nitrospirae, in association with the hydrogenotrophic methanogen Archaeoglobaceae and acetoclastic Methanosaeta, were highly represented. Genomes for Ca. Odinarchaeota and the hydrogen-dependent methylotrophic Ca. Methanosuratus were also recovered from the methanogenic culture. The sulfate-reducing community was dominated by Firmicutes, Thermotogae, Nitrospirae, Archaeoglobus, and several candidate taxa including Ca. Bipolaricaulota, Ca. Aminicenantes, and Candidate division WOR-3. These candidate taxa were key pantothenate producers for other community members. The study expands present knowledge of the metabolic roles of petroleum-degrading microbial communities under high-pressure conditions. Our results also indicate that microbial community interactions were shaped by syntrophic metabolism and the exchange of amino acids and cofactors among members. Furthermore, incubation under in situ pressure conditions has the potential to reveal the roles of microbial dark matter.

“…The critical anaerobic pathways associated with microbial oil reservoir consortia are the sulphate-reducing pathway (SRP), nitrate-reducing pathway (NRP), and methanogenic pathway [8,12]. SRP involves SRB such as Desulfovibrionales, Desulfuromonadales, and Desulfobacterales [128], which consume sulphate and sulphite, together with hydrocarbons and fatty acids in the form of terminal electron acceptors (TEA), to reduce them to H 2 S gas, and thus leading to crude oil saturation and corrosion in the reservoir [52,75].…”

Exploiting Microbes in the Petroleum Field: Analyzing the Credibility of Microbial Enhanced Oil Recovery (MEOR)

Crude oil is a major energy source that is exploited globally to achieve economic growth. To meet the growing demands for oil, in an environment of stringent environmental regulations and economic and technical pressure, industries have been required to develop novel oil salvaging techniques. The remaining ~70% of the world’s conventional oil (one-third of the available total petroleum) is trapped in depleted and marginal reservoirs, and could thus be potentially recovered and used. The only means of extracting this oil is via microbial enhanced oil recovery (MEOR). This tertiary oil recovery method employs indigenous microorganisms and their metabolic products to enhance oil mobilization. Although a significant amount of research has been undertaken on MEOR, the absence of convincing evidence has contributed to the petroleum industry’s low interest, as evidenced by the issuance of 400+ patents on MEOR that have not been accepted by this sector. The majority of the world’s MEOR field trials are briefly described in this review. However, the presented research fails to provide valid verification that the microbial system has the potential to address the identified constraints. Rather than promising certainty, MEOR will persist as an unverified concept unless further research and investigations are carried out.

foi usado em testes de atividade antifúngica contra onze linhagens de fungos fitopatogênicos, onde foi observada completa inibição do crescimento das hifas em Moniliophthora perniciosa, Phytophthora sojae e Lasidiplodia euphorbicola e inibição parcial em Ceratocystis paradoxa, Sclerotinia sclerotiorum, Rhizopus microsporus, Aspergillus flavus e Aspergillus niger. A atividade do tensoativo também foi testada contra as linhagens bacterianas Bacillus subtilis (ATTC 6633 e 21332), Staphylococcus epidermidis (ATTC 12228 e 35984), Pseudomonas fluorescens (ATTC 13525), Escherichia coli (ATTC 25922) e Desulfovibrio marinus BRS-1. Nos testes de microdiluição o biossurfactante causou uma inibição inicial pronunciada no crescimento de B. subtilis 6633, S. epidermidis (12228 e 35984), e moderada em P. fluorescens 13525. Sobre a bactéria redutora de sulfato D. marinus BRS-1 o biossurfactante mostrou ação bacteriostática e bactericida nas concentrações 2.250e 2.500 µg/mL, respectivamente. O tensoativo semipurificado teve sua capacidade de recuperação de óleo em meio poroso avaliada pelo método de lavagem de areia, sendo capaz de remover, aproximadamente, 30% do óleo de motor (10W40) presente na amostra. O bissurfactante produzido pela linhagem estudada mostrou potencial aplicação em processos de MEOR e biorremediação de óleo, além de ser capaz de inibir o crescimento de fungos e bactérias, podendo ter utilidade com agente de biocontrole.
