Due to the large number of areas contaminated with TPH, there is significant interest in biological remediation technology research, offering a comprehensive and sustainable approach soil decontamination health recovery at same time. This study aimed investigate effectiveness remediating TPH-contaminated (6120 mg kg−1) using Lotus corniculatus along microorganism consortium (GTC-GVT/2021) isolated from historic sites. evaluated removal TPH through changes nutrient content, enzymatic activity, microbiological community. The growth L. was reduced soil, particularly affecting root biomass by 52.17%. Applying inoculum positively affected total plant uncontaminated (51.44%) (33.30%) soil. GTC-GVT/2021 significantly enhanced degradation after 90 days 20.8% conjunction 26.33% compared control. activity more pronounced treatments, most cases, presence led higher activity. cultivation resulted an increased concentration inorganic P, NH4+, water-soluble phenols while no rise NO3− observed.

Contamination of soil by spills crude oil and oilfield brine is known to affect the species composition functioning microbial communities. However, effect such contamination on nitrogen cycling, an important biogeochemical cycle in tallgrass prairie soil, less well known. Detecting nitrate-reducing (NR) denitrifying (DN) bacteria via PCR amplification genes essential for these processes depends how primers match sequences bacteria. In this study, we enriched NR DN from oil/brine contaminated 5-10 years previously versus those cultured uncontaminated confirmed capacity 75 strains isolated enrichments reduce nitrate and/nitrite, then screened with specific seven functional genes. The comprised a phylogenetically diverse group bacteria, proportionately more γ-Proteobacteria oil-contaminated sites Bacilli brine-contaminated sites, suggesting some residual contaminants distribution. Around 82% shown nitrate/nitrite would not be identified as battery used. Our results indicate urgent need expand NR/DN gene primer database first identifying novel through their nitrate/nitrite.

Abstract With the rapid development of global oil industry, problem oil‐contaminated soil has become increasingly prominent, posing a serious threat to natural environment and human health. Therefore, bioremediation technology as an environmentally friendly cost‐effective solution been widely studied concerned. This paper reviewed progress application status for soil, analyzed classification principle technology. Through comprehensive analysis actual cases at home abroad, effects challenges are comprehensively evaluated. These not only show remarkable effect this in treatment but also reveal problems existing its practical application. On basis, future direction is prospected.

Respiration activities, growth kinetics, changes composition during biodegradation process elucidated using gas chromatography with mass spectrometry, respirometry, Bradford analysis. Growth conditions optimised for improved by cells multifactor They included simultaneous addition 1.3 g·L−1 granular sugar 0.25 yeast extract. twofold stimulation individual hydrocarbons (n-pentadecane, n-hexadecane n-heptadecane) demonstrated when glycolipid Rhodococcus-biosurfactants added 1.4 g·L−1.
