Abstract In the present study, three potentially Pb(II)-resistant and biosurfactant-producing bacterial strains were isolated from a total of 23 strains using various screening methods, investigated for their biosorption of Pb(II) and used for the biodegradation of used motor oil. The results show that strain E1 (Bacillus haynesii) has significantly high efficiency in biodegradation of used motor oil, up to 82 % in the first three days. Maximum Pb(II) biosorption capacities of 238.09 mg/g and 99.01 mg/g were determined for strains E1 and F5 (Pseudomonas aeruginosa), respectively. The biosorption process was found to be in good agreement with the Langmuir isotherm for both E1 (R2 = 0.9614) and F5 (R2 = 0.9646), suggesting monolayer biosorption. The four common screening methods, namely the haemolytic assay, the determination of surface tension, the emulsifying activity and the foam test, were also correlated with the Pearson correlation method.

Road deterioration inspires researchers to enhance the properties of asphalt binder for better performing mixes. Recycled tire rubber, or crumb rubber modifier (CRM), and used motor oil (UMO) are two modifiers that enhance asphalt binder performance through two different mechanisms. CRM affects high-temperature properties while UMO modifies low-temperature properties. Potential environmental concerns arising from the use of UMO have been raised in the literature. In this paper, the two recycled materials were investigated for their ability to complement each other. Both performance benefits of using both materials and the environmental concerns of using UMO were studied. Four CRM asphalt binders were investigated: two with UMO and two without UMO. Environmental impacts were evaluated using gas chromatography to check air emissions for benzene, toluene, ethyl-benzene, and xylenes (BTEX). The potential for toxic leaching of elements from modified hot mix asphalt (HMA) were checked using the US Environmental Protection Agency (EPA) Toxicity Characteristic Leaching Protocol (TCLP). For asphalt binders modified by CRM-UMO combinations, CRM decreased the amounts of released BTEX components, presumably by absorbing UMO and slowing the release of BTEX. Leaching results concluded that UMO mixtures showed a notable percentage of sulfur (S) as compared to non-UMO mixes. All these leachate components were under EPA limits.
