“…In addition, the emulsification test is one of the standard assays for biosurfactant production assessment. These molecules have a beneficial interest in microbial-enhanced oil recovery as they lower the surface tension at the oil–water interface, resulting in enhanced pollutants’ availability to microorganisms [ 7 ].…”

“…Therefore, without proper waste-handling systems, the extensive range of vehicular waste from maintenance activities and derived petroleum products comprising used motor oil, brake lubricants, gasoline, and diesel are usually directly dumped onto the soil [ 1 , 2 , 3 , 4 , 5 ]. Moreover, the hydrocarbon molecules constitutive of petroleum products are persistent in the environment and bioaccumulate in living organisms with harmful after-effects [ 6 , 7 ]. The contaminants are also subjected to leaching phenomena due to rains or domestic water that drain them underground and outside the mechanic workshop area, therefore expanding the pollution [ 3 ].…”

“…Finally, an attempt to recover strains usable in future bioaugmentation strategies involving allochthonous microorganisms was conducted by isolating bacteria able to grow using petroleum hydrocarbons as carbon sources and producing biosurfactants. Indeed, biosurfactant molecules enhance hydrocarbon bioavailability, a critical factor for the successful degradation of these compounds [ 7 ]. The use of biosurfactants-producing bacteria is advantageous for implementing a bioaugmentation strategy.…”

Bioaugmentation is a valuable technique for oil recovery. This study investigates the composition and functions of microbial communities in gasoline- and diesel-contaminated soils of garages Matoko (SGM) and Guy et Paul (SGP) originating from auto mechanic workshops as well as the concentration of soil enzymes β-glucosidase, β-glucosaminidase, and acid phosphatase. The work aimed to evaluate the presence of petroleum-hydrocarbon-degrading bacteria for the development of foreseen bioremediation of oil-contaminated soils. Microbial diversity, as given by shotgun metagenomics, indicated the presence of 16 classes, among which Actinobacteria and Gammaproteobacteria dominated, as well as more than 50 families, including the dominant Gordoniaceae (26.63%) in SGM and Pseudomonadaceae (57.89%) in SGP. The dominant bacterial genera in the two soils were, respectively, Gordonia (26.7%) and Pseudomonas (57.9%). The exploration of the bacterial metabolic abilities using HUMANn2 allowed to detect genes and pathways involved in alkanes and aromatic hydrocarbons in the two contaminated soils. Furthermore, enzymes β-glucosidase, β-glucosaminidase, and acid phosphatase were found in high concentrations ranging between 90.27 ± 5.3 and 804.17 ± 20.5 µg pN/g soil/h, which indicated active microbial metabolism. The high diversity of microorganisms with a hydrocarbon degradation genetic package revealed that the bacteria inhabiting the two soils are likely good candidates for the bioaugmentation of oil-contaminated soils.

“…-Genetic bioaugmentation. Genetically modified organisms have also been shown to improve stability and resistance to environmental stressors, and their prolonged viability results in greater effectiveness [ 49 , 50 , 51 ]. Bioaugmentation with Pseudomonas putida KT2440, harbouring the transferrable triclocarban-catabolic plasmid pDCA-1- gfp-tccA2 , rapidly converted 50 μM triclocarban in WW into 3,4-dichloroaniline and 4-chloroaniline, which were further mineralised more easily [ 52 ].…”

Bioaugmentation is widely used in soil bioremediation, wastewater treatment, and air biofiltration. The addition of microbial biomass to contaminated areas can considerably improve their biodegradation performance. Nevertheless, analyses of large data sets on the topic available in literature do not provide a comprehensive view of the mechanisms responsible for inoculum-assisted stimulation. On the one hand, there is no universal mechanism of bioaugmentation for a broad spectrum of environmental conditions, contaminants, and technology operation concepts. On the other hand, further analyses of bioaugmentation outcomes under laboratory conditions and in the field will strengthen the theoretical basis for a better prediction of bioremediation processes under certain conditions. This review focuses on the following aspects: (i) choosing the source of microorganisms and the isolation procedure; (ii) preparation of the inoculum, e.g., cultivation of single strains or consortia, adaptation; (iii) application of immobilised cells; (iv) application schemes for soil, water bodies, bioreactors, and hydroponics; and (v) microbial succession and biodiversity. Reviews of recent scientific papers dating mostly from 2022–2023, as well as our own long-term studies, are provided here.

Oil/water separation is an important pursuit because of the increasing worldwide oil pollution. The key to solving this problem is to develop high-performance materials and improve their separation efficiency. Polyurethane composite foam (PUCF) possesses large specific surface area, high open porosity, and good mechanical properties which have been developed for oil/water separation. This paper mainly summarizes the research progress of PUCF materials in oil/water separation, including the surface-wetting theory, the intrinsic wetting threshold theory, the main factors affecting the separation performance of foam materials, and the recent research status of the PUCF materials in oil/water separation. Finally, we look forward to the research focus on urgent problems that should be addressed for PUCF in oil/water separation, which will provide new strategies for further developing next-generation high-performance foam materials for oil/water separation.
