“…This may have long-term consequences on the ecosystem. Proper monitoring plans and restoration counteraction are required, as severe toxicological effects of oil on the marine communities, from the microbial communities to the mammals, have been already detailed by several studies (reviewed in [10]).…”

In light of the recent marine oil spill that occurred off the coast of Mauritius (Indian Ocean), we comment here the incident, the containment method used by the local population, the biological impact of oil spill on two sensitive tropical marine ecosystems (coral reefs and mangrove forests), and we suggest monitoring and restoration techniques of the impacted ecosystems based on recent research advancements.

“…The pair-wise alignment of the obtained sequence with sequences in the database showed that the obtained sequence was identical to Streptomyces macrosporeus (Accession # HQ607420) with a homology sequence of about 98.65%. The phylogenetic tree presented in Figure (1) corresponds to the partial 16S rDNA gene phylogeny of the order bacteria.…”

“…This caused an increased accumulation of CO2, unburnt hydrocarbons, particulate matter, oxides of sulfur and nitrogen, and other persistent organic pollutants. Yuewen and Adzigbli [1] indicated that oil pollutants in the marine environment have diverse effects on marine organisms. One of the most widespread organic environmental pollutants is polycyclic aromatic hydrocarbons (PAHs) which pose a potential risk to human health via marine biota [2] .…”

Samples from the River Nile, the Mediterranean, and the Red Sea were chemically and microbiologically evaluated. The chemical analysis proved that cations and anions concentrations were of higher values in seawater samples in comparison with those of the Nile water. The microbiological analysis showed that Cairo University Nile Bus Station samples (GCB-19) recorded the increased total viable microbial counts (1.6x10 4 CFU/ml). Total coliforms highest counts were analyzed in GCB-19 samples (110 cells/ml), whereas fecal coliforms highest counts (15 cells/ml) were recorded in Cairo University Nile Bus Station samples (GCB-17) and (GCB-19). PAHs were determined in the collected samples using GC/MS. Seawater samples had increased concentrations of PAHs in comparison with River Nile water ones. Fluorene was the major PAH in all water samples, for it ranged from 25 to 50 ppt. An actinomycetes isolate from the collected samples underwent molecular identification through the pair-wise alignment of its 16S rDNA sequence with sequences in the database. It was indicated that it was identical to Streptomyces macrosporeus with a 98.65% homology sequence. Streptomyces macrosporeus was examined for degradation efficiency of 0.1, 0.05, 0.025, and 0.0125 ppm of PAHs standard mix and 200 ppm of naphthalene, fluorene, and anthracene, individually for 5 days/37 o C. It degraded all the detectable concentrations of the chemicals in the PAHs standard mix except for some non-degradable traces of naphthalene. Furthermore, it degraded naphthalene, fluorene and anthracene individually with a percentage of 99.99%, 94.88%, and 96.33%, respectively. Thus, the results of the current study reflected the biodegradation capability of Streptomyces macrosporeus for different PAHs.

“…Oil spills are described as the release of hydrocarbon compounds of oil and other chemical traces (sulfur and heavy metals) by accident into the marine environment. The discharge of oil into the seawater can cause harmful impacts on the environment and interfere with the ecological system, which affects the quality of life of living organisms [ 3 , 4 , 5 ]. Various remediation methods have been used to remove oil in contaminated water, e.g., floating oil booms, skimmers, pumps, in situ burning, dispersants, adsorbents, and bioremediation [ 1 ].…”

A Silica–Lignin Hybrid Filler in a Natural Rubber Foam Composite as a Green Oil Spill Absorbent

Oil spills in the marine environment are a rising concern due to their adverse impacts on living creatures and the environment. Hence, remediation methods have been used to remove the oil from the contaminated water. A sorbent material is considered the best method for oil spill absorption. However, commonly used commercial sorbents are made from nonrenewable and nonenvironmentally friendly materials. In this research, natural rubber foam (NRF) was used as a sorbent material with the addition of a filler, i.e., silica and a silica–lignin hybrid, to increase its oil sorption capacity and reusability. The silica and silica–lignin hybrid were extracted from rice husk waste by means of the precipitation method. The silica–lignin hybrid-filled NRF exhibited excellent hydrophobicity, with a water contact angle of 133°, and had more stable reusability compared to unfilled NRF and silica-filled NRF. In addition, the optimum oil absorption capacity of silica–lignin hybrid-filled NRF was 1.36 g g−1. Overall, the results showed that silica–lignin hybrid-filled NRF has the potential to be developed as a green oil absorbent material and is promising in terms of economic and environmental aspects.
