“…Firstly, BS molecules can dissolve contaminants, making them more accessible to microorganisms and increasing their bioavailability. Secondly, BS can alter microorganisms' hydrophobicity, allowing them to adhere to the contaminants directly [70,77]. This helps to promote better contact between the microbes and pollutants, resulting in increased metabolic activity and improved contaminant degradation [78].…”

This study aims to assess the impact of HydroBreak PLUS biosurfactant on the phytoremediation of diesel-contaminated soil by three legume plant species: Medicago sativa, Lotus corniculatus, and Melilotus albus. Legumes were grown in soil contaminated with diesel (4.0 g kg−1, 6.0 g kg−1) for 90 days, and the changes in soil diesel and nutrient concentrations, plant growth, and physiological parameters were measured. Diesel negatively affected the biomass production of all legumes, though the reduction in growth rate was observed only in L. corniculatus and M. albus. L. corniculatus had the highest diesel removal rate of 93%, M. albus had the lowest of 87.9%, and unplanted treatments had significantly lower diesel removal rates (up to 66.5%). The biosurfactant mitigated diesel-induced reduction in plant shoot and root weight and an increase in L. corniculatus root biomass (24.2%) were observed at 4.0 g kg−1 diesel treatment. The use of biosurfactant accelerated diesel removal from the soil, though the effect was diesel soil concentration and plant species-dependent. In unplanted treatments, the diesel removal rates increased by 16.4% and 6.9% in the treatments with 4 and 6 mg kg−1, respectively. The effect of biosurfactants on diesel removal by plants was less pronounced and reached 4.6% and 3.2% in the treatments with 4 and 6 mg kg−1, respectively. The study revealed that the phytoremediation efficiency could not be directly linked to plant physiological parameters as only M. sativa changes in plant growth corresponded well with photosystem II performance. Implementation of legumes and biosurfactants has a positive effect on soil quality by its enrichment with inorganic P and soluble phenols, while no enrichment in NO3− and NH4+ was observed.

“…Por otra parte, el suelo experimental resultó ser franco arenoso (tabla III) por lo que los contaminantes derivados del petróleo pueden permanecer durante mucho tiempo y acumularse gradualmente ya que este suelo se caracteriza por ser más poroso que los demás y permite la absorción de los hidrocarburos [28]. Las características iniciales en el suelo sin contaminar (tabla IV) presentaron un pH de 8.2 ligeramente alcalino, la C.E.…”

Resumen-Soil contamination by hydrocarbons generates serious impacts on the fertility, properties and use of the soil; it can also affect human health, flora and fauna. The main objective of this research was to evaluate the degradation of total petroleum hydrocarbons (TPH) in a soil modified with manure from Cavia porcellus and Helianthus annuus. For this, 4 treatments were carried out with 3 repetitions in each one consisting of 1.6 kg soil + 0.8 kg sand + 20,000 ppm B5 S-50 diesel and a sunflower specimen, treatments 2, 3 and 4 added 100, 200 and 300 g of guinea pig manure respectively. Physical-chemical analyzes of the soil and manure were carried out, the HTP concentrations were measured in a gas chromatograph. The results of the treatments showed highpercentages of HTP remediation with 75.47%, 99.76%, 99.43% and 99.39% in treatment 1; 2; 3 and 4 respectively. Finally, it was concluded that the incorporation of guinea pig manure and sunflower plantation in a soil contaminated by B5 S-50 diesel turned out to be an effective method in the degradation of HTP, considering that these variables had positive results after obtaining percentages absorption greater than 99%.

“…The V3 to V4 region of the 16S ribosomal RNA (rRNA) gene was amplified with primer 338F (5′-ACTCCTACGGGAGGCAGCAG-3′) and 806R (5′-GGACTACHVGGGTWTCTAAT-3′) ( Bao et al, 2022 ). Polymerase chain reaction (PCR) cycles were performed as follows: initial denaturation at 95 ° C for 3 min, followed by 27 cycles of heat and cooling, 95 ° C for 30 s, 55 ° C for 30 s, 72 ° C for 45 s, and kept at 72 ° C for 10 min.…”

The gut microbiome and its interaction with host have been implicated as the causes and regulators of colorectal cancer (CRC) pathogenesis. However, few studies comprehensively investigate the compositions of gut bacteria and their interactions with host at the early inflammatory and cancerous stages of CRC. In this study, mouse fecal samples collected at inflammation and CRC were subjected to microbiome and metabolome analyses. The datasets were analyzed individually and integratedly using various bioinformatics approaches. Great variations in gut microbiota abundance and composition were observed in inflammation and CRC. The abundances of Bacteroides, S24-7_group_unidifineted, and Allobaculum were significantly changed in inflammation and CRC. The abundances of Bacteroides and Allobaculum were significantly different between inflammation and CRC. Furthermore, strong excluding and appealing microbial interactions were found in the gut microbiota. CRC and inflammation presented specific fecal metabolome profiling. Fecal metabolomic analysis led to the identification and quantification of 1,138 metabolites with 32 metabolites significantly changed in CRC and inflammation. 1,17-Heptadecanediol and 24,25,26,27-Tetranor-23-oxo-hydroxyvitamin D3 were potential biomarkers for CRC. 3α,7β,12α-Trihydroxy-6-oxo-5α-cholan-24-oic Acid and NNAL-N-glucuronide were potential biomarkers for inflammation. The significantly changed bacterial species and metabolites contribute to inflammation and CRC diagnosis. Integrated microbiome and metabolomic analysis correlated microbes with host metabolites, and the variated microbe-metabolite association in inflammation and CRC suggest that microbes facilitate tumorigenesis of CRC through interfering host metabolism.
