“…Finally, Thalassospira is a genus that was recently created in 2002, and currently have eight validated species belonging to the Rhodospirillaceae family. There is one study that reported a Thalassospira strain as lipase producer [46], and some for biodegradation of oil sludge [47]. Thalassospira are known to possess powerful oxidizing enzymes, and certain species have even been reported to degrade hydrocarbons such as hexadecane, benzene, toluene, naphthalene, phenanthrene, anthracene, benzo(a)pyrene, and crude oil [48] and polyvinyl‐alcohols [49].…”

Microbial communities capable of hydrocarbon degradation linked to biosurfactant (BS) and bioemulsifier (BE) production are basically unexplored in the Gulf of México (GOM). In this work, the BS and BE production of culturable marine bacterial hydrocarbonoclasts consortia isolated from two sites (the Perdido Fold Belt and Coatzacoalcos area) was investigated. The prospection at different locations and depths led to the screening and isolation of a wide variety of bacterial consortia with BS and BE activities, after culture enrichment with crude oil and glycerol as the carbon sources. At least 55 isolated consortia presented reduction in surface tension (ST) and emulsifying activity (EI24). After colony purification, bacteria were submitted to polyphasic analysis assays that resulted in the identification of different strains of cultivable Gammaproteobacteria Gram (−) Citrobacter, Enterobacter, Erwinia, Pseudomonas, Vibrio, Shewanella, Thalassospira, Idiomarina, Pseudoalteromonas, Photobacterium, and Gram (+) Staphylococcus, Bacillus, and Microbacterium. Overall, the best results for ST reduction and EI24 were obtained with consortia. Individually, Pseudomonas, Bacillus, and Enterobacter strains showed the best results for the reduction of ST after 6 days, while Thalassospira and Idiomarina strains showed the best results for EI24 (above 68% after 9 days). Consortia isolates from the GOM had the ability to degrade crude oil by up to 40–80% after 24 and 36 months, respectively. In all cases, biodegradation of crude oil was related to the reduction in ST and bioemulsifying activity and was independent from the depth in the water column.

“…All sludges showed low C11-C22 aromatic fraction concentrations, 1% -8% (Figure 3). In fact, the aliphatic fraction concentrations in oil sludges are usually higher than the aromatic fractions (Ward et al, 2003, Jasmine and Mukherji, 2015, Kadiev et al, 2015, Shahidi Rizi et al, 2017.…”

potentially toxic elements (PTEs) are believed to come from oil additives (de Souza et al., 2014).da Silva et al. (2012) reported that the composition of oil sludge is about 30 to 90% water, 4 to 7% sediments, and to 60% oil. However, Saikia et al. (2003) stated that the typical composition of oil sludge is 30-50% water, 10-12% sediments and solids, 30-50% oil. Yang et al. (2005), Zhang et al. (2012), and Long et al. (2013 have agreed that oil sludge is usually composed of 30-70% water, 2 to 15% sediments and solids, and 30-90% oil. Moreover, Egazar'yants et al. (2015) mentioned that oil sludges can have approximately 10 to 56 wt.% organic materials, 30 to 85 wt.% water and 1 to 46 wt.% solids or sediments. This shows that there is no uniform agreement among authors on the detailed oil sludge composition. This is not surprising since each oil sludge composition is unique, and depends on the origin of the oil sludge (Viana et al., 2015). Consequently, the physicochemical characteristics vary according to the nature of the oil (Oliveira et al., 2015) and the formation process and storage of the oil sludge (Kadiev et al., 2015). Generally, the sediment content is less than the oil and water contents. The oil usually had higher aliphatic hydrocarbon percentages (40-60%) than the aromatic hydrocarbon percentages (25-40%) (Shie et al., 2004, Speight, 2006. This wide variation in the composition of oil sludges has significant implications on the characterisation of oil sludges because different procedures and methods have been applied to study different types of sludges (Heidarzadeh et al., 2010, Wang et al., 2010, Zhang et al., 2011, Jasmine and Mukherji, 2015. In turn, this is extremely relevant for quick decision-making purposes regarding the appropriate treatment of this waste. Currently, the treatment of oil sludges is aimed to either reduce the contaminants in the sludge or to recover the oil. The former includes some methods such as encapsulation (Johnson et al., 2015), bioremediation (Wang et al., 2016, Roy et al., 2018), and incineration (Gong et al., 2017 whereas the latter, the oil recovery methods, include freeze/thawing (Hu et al., 2015), solvent extraction (Hu et al., 2017, * These elements are potentially toxic elements (PTEs) (Shaheen et al., 2016).Values in bold are over the limit of the acceptable standards of landfilling of hazardous waste established by the European Union: As (25 µg•g -1 ), Cd (5), Cr (70), Cu (100), Ni (40), Pb (50), Zn (200) (Kriipsalu et al., 2008). The mean values with the standard deviation (in parentheses) are shown (n = 3).
