“…At present, different cleanup and recovery methods for the oil spills have been developed including physical (e.g., controlled burning, skimming, and absorbing), chemical (e.g., dispersing and solidifying), and bioremediation treatments [2,8,38,50]. Generally, physical and chemical treatments should be taken as emergency measures.…”

Due to the toxicity of petroleum compounds, the increasing accidents of marine oil spills/leakages have had a significant impact on our environment. Recently, different remedial techniques for the treatment of marine petroleum pollution have been proposed, such as bioremediation, controlled burning, skimming, and solidifying. (Hedlund and Staley in Int J Syst Evol Microbiol 51: [61][62][63][64][65][66] 2001). This review introduces an important remedial method for marine oil pollution treatment-bioremediation technique-which is considered as a reliable, efficient, cost-effective, and eco-friendly method. First, the necessity of bioremediation for marine oil pollution was discussed. Second, this paper discussed the species of oil-degrading microorganisms, degradation pathways and mechanisms, the degradation rate and reaction model, and the factors affecting the degradation. Last, several suggestions for the further research in the field of marine oil spill bioremediation were proposed.

“…Biodegradation of hydrocarbons is relevant to bioremediation of oil-polluted environments (Dubinsky et al, 2013;Mason et al, 2014) as well as to understanding the mechanisms involved in microbe-enhanced oil recovery (MEOR) technologies that are based on growth and activity of hydrocarbon-degrading bacteria and microbial consortia (Bachmann et al, 2014;Bødtker et al, 2009;Kowalewski et al, 2005).…”

Abyssivirga alkaniphila gen. nov., sp. nov., an alkane-degrading, anaerobic bacterium from a deep-sea hydrothermal vent system, and emended descriptions of Natranaerovirga pectinivora and Natranaerovirga hydrolytica A strictly anaerobic, mesophilic, syntrophic, alkane-degrading strain, L81 T , was isolated from a biofilm sampled from a black smoker chimney at the Loki's Castle vent field. Cells were straight, rod-shaped, Gram-positive-staining and motile. Growth was observed at pH 6.2-9.5, 14-42 8C and 0.5-6 % (w/w) NaCl, with optima at pH 7.0-8.2, 37 8C and 3 % (w/w) NaCl. Proteinaceous substrates, sugars, organic acids and hydrocarbons were utilized for growth. Thiosulfate was used as an external electron acceptor during growth on crude oil. Strain L81 T was capable of syntrophic hydrocarbon degradation when co-cultured with a methanogenic archaeon, designated strain LG6, isolated from the same enrichment. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain L81 T is affiliated with the family Lachnospiraceae, and is most closely related to the type strains of Natranaerovirga pectinivora (92 % sequence similarity) and Natranaerovirga hydrolytica (90 %). The major cellular fatty acids of strain L81 T were C 15 : 0 , anteiso-C 15 : 0 and C 16 : 0 , and the profile was distinct from those of the species of the genus Natranaerovirga. The polar lipids were phosphatidylglycerol, diphosphatidylglycerol, three unidentified phospholipids, four unidentified glycolipids and two unidentified phosphoglycolipids. The G+C content of genomic DNA was determined to be 31.7 mol%. Based on our phenotypic, phylogenetic and chemotaxonomic results, strain L81 T is considered to represent a novel species of a new genus of the family Lachnospiraceae, for which we propose the name Abyssivirga alkaniphila gen. nov., sp. nov. The type strain of Abyssivirga alkaniphila is L81 T (5DSM 29592 T 5JCM 30920 T ). We also provide emended descriptions of Natranaerovirga pectinivora and Natranaerovirga hydrolytica.

“…The notion of recovering nutrients other than sulphur from the leachate of biofilters is not new (Dumont et al 2012a;Jung et al 2005;Rabbani et al 2015;Rabbani et al 2016;Zhang et al 2013). Removal and recovery of elemental sulphur from coal, natural gas and high sulphur crude oils is well-recognised processes, but recovery of sulphur from dilute streams of acid from wastewater treatment plants has not been previously attempted (Babich and Moulijn 2003;Bachmann et al 2014;Jiang et al 2015;Meshram et al 2015;Shu et al 2014). Dilute sulphuric acid solutions produced in industry are concentrated by energy-intensive processes using high-temperature conversion of acid to sulphur dioxide and subsequent catalytic conversion of sulphur dioxide to concentrated sulphuric acid (Smith and Mantius 1978).…”

Biofilter for generation of concentrated sulphuric acid from H2S

Biofilters are used for the conversion of odorous hydrogen sulphide to odourless sulphate in wastewater treatment plants under the right conditions of moisture and pH. One of the consequences of maintaining the suitable pH and moisture content is the production of large volumes of weakly acidic leachate. This paper presents a biofilter with a maximum H2S elimination capacity of 16.3 g m −3 h −1 and removal efficiency greater than 95 % which produces small volumes (1 mL of solution L −1 of reactor day −1 ) of sulphuric acid with a concentration greater than 5.5 M after 150 days of continuous operation. The concentrated sulphuric acid was produced by intermittently trickling a minimum amount of nutrient solution down the upflow biofilter which created a moisture and pH gradient within the biofilter resulting in an environment at the top for the bacterial conversion of H2S, while sulphuric acid was accumulated at the base. Genetic diversity profiling of samples taken from different sections of the biofilter confirms that the upper sections of the biofilter had the best environment for the bacteria to convert H2S to sulphate. The formation of concentrated sulphuric acid presents an opportunity for the recovery of sulphur from the waste stream as a usable product.
