Summary: A greenhouse experiment was conducted to evaluate the effect of phytoremediation and biochar application on hydrocarbon degradation in crude oil-contaminated soils. The experiment involved four levels of biochar application (0, 5, 10, and 15 t/ha) and the presence or absence of Vigna unguiculata (cowpea; +C, -C), replicated three times in a 4 x 2 x 3 factorial design. The results showed that the highest degradation efficiency of 69.2% (7033 mg/kg) was achieved in contaminated soils amended with 15 t/ha biochar after 60 days of incubation. Significant interactions were observed between biochar x plant and biochar x days. Biochar also enhanced plant growth in contaminated soils.

Summary: This study conducted bioaugmentation of crude oil/motor oil contaminated soil using a mixture of novel strains Pseudomonas aeruginosa PP3 and Pseudomonas aeruginosa PP4. Four different bioaugmentation systems were implemented, and the effectiveness was monitored by investigating the total petroleum hydrocarbon (TPH) removal rate. The results showed that BS 4 (BS 3 + bacterial consortia) had the highest TPH removal rate of 67%, followed by BS 2 (BS 1 + bacterial consortia) with a removal rate of 52%. GCMS analysis revealed that BS 2 and BS 4 achieved 65% and 83% biodegradation efficiency (BE) of residual crude and motor oil contaminated soil, respectively. Plant cultivation experiments demonstrated that Lablab purpureus grew more rapidly in BS 2 and BS 4 systems compared to BS 1 and BS 2, indicating the suitability of the bioaugmented soil for plant growth.

Summary: In order to improve the bioremediation efficiency of petroleum-contaminated soil, five test groups were selected in this study. The results showed that there was no significant difference in the removal efficiency of TPH between native bacteria and A.V. bacteria group. However, the cultivation of Vetiveria zizanioides L. could significantly increase the removal efficiency of TPH.

Summary: This study investigated the application of bioremediation with sinusoidal alternating current electric fields for soil remediation, showing that the AC+BIO system was more efficient in removing petroleum hydrocarbons compared to BIO or AC alone. The study also found that the appropriate AC voltage gradient had an impact on microbial communities and TPH degradation efficiency. Further research and practical applications are warranted based on the insights provided by this study.

Summary: This review explores the mechanisms and effects of organic amendments in the enhanced remediation of TPH-contaminated soils, focusing on the importance of increased TPH sorption and desorption for improving soil health and facilitating biodegradation. The uncertainty of mechanisms for various organic amendments in TPH remediation processes remains a critical area for future research.

Summary: This study investigated the effects of different nitrogen sources and microorganisms on the removal of hydrocarbons and conversion of nitrogen in aqueous environments. The results showed that the combination of NO3- -N and the Meyerozyma consortium exhibited better degradation of petroleum hydrocarbons and stimulated the activity of Stenotrophomonas. Hydrocarbon transformation and nitrogen balance analysis revealed the important roles of the Meyerozyma consortium and Stenotrophomonas in hydrocarbon degradation and nitrogen cycling.

Summary: Oil-contaminated environments are enriched with microorganisms that can utilize petroleum for growth and metabolic activities. Three isolates were identified as Pseudomonas sp., Acinetobacter sp., and Enterobacter sp. respectively. The isolates showed degradation efficacy in diesel oil and burned engine oil, indicating their potential use for bioremediation purposes.

Summary: This study proposes a strategy to reduce the viscosity of crude oil by using solar-assisted chemical emulsifiers, and modify commercial sponges to achieve rapid adsorption and efficient recovery of crude oil. The modified sponge exhibits a 10% increase in absorption capacity and a three order of magnitude increase in viscous crude oil absorption rate compared to a commercial polyurethane sponge.

Summary: Crude oil contamination severely impacts soil quality. Bioremediation utilizing soil indigenous organisms offers a cost-effective and environmentally friendly approach for petroleum hydrocarbon decomposition. However, slow kinetics hinder the efficacy of this biotechnique. This study investigates the use of Fenton pre-oxidation and biostimulated iron to enhance the bioremediation process for oil-contaminated soil. Results show that the combination of Fenton pre-oxidation and biostimulated iron promotes the rapid growth of indigenous petroleum-degrading bacteria (IPDB) and increases the degradation of total petroleum hydrocarbons (TPH) in soil. However, the use of non-biostimulated iron in Fenton pre-oxidation fails to sustain IPDB propagation during subsequent bioremediation.

Summary: Halotolerant strain CO100 of Staphylococcus sp. isolated from contaminated sediments in Tunisia showed efficient hydrocarbon degradation ability and synthesized a lipopeptide biosurfactant BS-CO100 with strong tensioactive properties under various conditions, non-cytotoxic to human cells. BS-CO100 also exhibited anti-biofilm and anti-adhesive activities, making it a promising candidate for bioremediation of oil-polluted areas, even under saline conditions.
