“…Monitors and co-management measures must be implemented to minimize the public health, ecological, and socioeconomic effects of this extensive spill. To elucidate the magnitude of the disaster and to contribute to the adequate restoration, we emphasize the urgent need for research focusing on the following issues: (1) levels and effects of contamination in tropical food webs; (2) environmental toxicity (PAHs -polycyclic aromatic hydrocarbons) from oil and its residues in populations and ecosystems not evaluated to date (e.g., fishes, oysters, rhodolith beds, and coral reefs) (Miranda et al 2020;Müller et al 2021;Soares et al 2021); (3) biomonitors, biomarkers (Almeida et al 2021), and microbial remediation of the oil spill (Appolinario et al 2019;Rodrigues et al 2020); and (4) monitoring of the acute and chronic ecological and socioeconomic impacts on traditional human communities and coastal ecosystems. Finally, there is a global concern regarding the impacts of mapping, exploitation, transportation, and uses of fossil fuels in the threatened world by climate change and the biodiversity crisis.…”

This article presents a synthesis of information about the massive oil spill in Brazil (2019/2020). The event affected 11 states; however, the majority of the oil residue was collected (~ 5380 tons) near nine states (99.8%) in northeastern Brazil. This spill was not the largest in volume (between 5000 m 3 and 12,000 m 3 ) recorded in tropical oceans, but it was the most extensive (2890 km). This spill develops an overwashed tar that remains mostly in the undersurface drift (non-floating oil plume) below 17 m of depth while on the continental shelf. Ten ecosystems were impacted, with potentially more severe effects in mangroves and seagrasses. Certain negative effects are still understudied, such as effects on tropical reefs and rhodolith beds. A total of 57 protected areas in seven management categories were affected, most of which (60%) were characterized as multiple-use regions. The spill affected at least 34 threatened species, with impacts detected on plankton and benthic communities. Acute impacts were reported on echinoderms, coral symbionts, polychaetes, and sponges with evidence of oil ingestion. Socioeconomic impacts were detected in food security, public health, lodging, gender equality, tourism, and fishing, with reduced sales, prices, tourist attractiveness, gross domestic product, and employment. Moreover, chemical contamination was detected in some states by toxic metals (Hg, As, Cd, Pb, and Zn) and polycyclic aromatic hydrocarbons (acenaphthalene, fluoranthene, fluorene, naphthalene, and phenanthrene). This summary aims to aid in the design of science-based strategies to understand the impacts and develop strategies for the most extensive spill observed in tropical oceans.

“…Solid inoculants of LZ-2 bacteria were found to degrade hydrocarbons found in crude oil (Li et al 2021 ). Bioaugmentation was also the rationale behind the use of bacterial strains Rhodococcus rhodochrous and Nocardia farcinia to successfully break down crude oil in water bodies (Rodrigues et al, 2020 ). Exiguobacterium sp.…”

Crude oil exploration in Africa: socio-economic implications, environmental impacts, and mitigation strategies

et al. 2021

Crude oil exploration is a source of significant revenue in Africa via trade and investment since its discovery in the mid-19th Century. Crude oil has bolstered the continent’s economy and improved the wellbeing of the citizenry. Historically, Africa has suffered from conflicts due to uneven redistribution of crude oil revenue and severe environmental pollution. Advancements in geophysical survey techniques, such as magnetic and gravity methods, to seismic methods, have made the commercial exploration of crude oil possible for some other countries in Africa apart from Nigeria, Angola, Algeria, Libya, and Egypt. The occurrence of organic-rich, oil-prone Type I, II, and mixed II/III kerogens in sedimentary basins and entrapment within reservoir rocks with intrinsic petrophysical properties are majorly responsible for the large deposits of hydrocarbon in Africa. The unethical practices by some multinational oil corporations have resulted in social movements against them by host communities and human rights groups. The unscrupulous diversion of public funds, award of oil blocks, and production rights to certain individuals have impaired economic growth in Africa. The over-dependence on crude oil revenues has caused the economic recession in oil-producing countries due to plummeting oil prices and global pandemic. Most host communities of crude oil deposits suffer from a lack of infrastructure, arable soils, clean water, and their functioning capabilities are violated by crude oil exploratory activities, without adequate compensations and remedial actions taken by oil companies and the government. Thus, this review examines crude oil exploration in Africa and provides insight into the environmental and socio-economic implications of crude oil exploration in Africa. Furthermore, this report highlights some recommendations that may ensure ethical and sustainable practices toward minimizing negative impacts and improving the quality of life in affected communities.

“…Additionally, the carbon source had a great influence on changes in bacterial physiology, including cell hydrophobicity, fatty acid profiles and biofilm formation 32 – 34 . Previous studies have focused on changes in bacterial properties in response to stress after exposure to toxic hydrocarbons 33 , 35 , 36 , but the preparation of toxic tolerant cells for enhanced biodegradation activity has not been reported. Moreover, types of bioreactors have gained considerable importance for large-scale production 37 .…”

For economic feasibility, sugarcane molasses (0.5%, w/v) containing K2HPO4 (0.26%, w/v) and mature coconut water, low value byproducts, were used in cultivation of Rhodococcus ruber S103 for inoculum production and immobilization, respectively. Physiological changes of S103 grown in low-cost media, including cell hydrophobicity, saturated/unsaturated ratio of cellular fatty acids and biofilm formation activity, enhanced stress tolerance and crude oil biodegradation in freshwater and even under high salinity (5%, w/v). Biobooms comprised of S103 immobilized on polyurethane foam (PUF) was achieved with high biomass content (1010 colony-forming units g−1 PUF) via a scale-up process in a 5-L modified fluidized-bed bioreactor within 3 days. In a 500-L mesocosm, natural freshwater was spiked with crude oil (72 g or 667 mg g−1 dry biobooms), and a simulated wave was applied. Biobooms could remove 100% of crude oil within only 3 days and simultaneously biodegraded 60% of the adsorbed oil after 7 days when compared to boom control with indigenous bacteria. In addition, biobooms had a long shelf-life (at least 100 days) with high biodegradation activity (85.2 ± 2.3%) after storage in 10% (w/v) skimmed milk at room temperature. This study demonstrates that the low-cost production of biobooms has potential for future commercial bioremediation.
