“…revealed the presence of various genes encoding enzymes involved in hydrocarbon degradation such as oxygenases, dehydrogenases, hydroxylases as well as different transporters and related transcriptional regulators (He et al, 2018;Das et al, 2020). Similarly, hydrocarbon degradation by numerous Stenotrophomonas strains have been reported (Behera et al, 2020;Larik et al, 2019). Kumari et al (2017) isolated a Stenotrophomonas sp.…”

We studied the biodegradation of oily sludge generated by a petroleum plant in Bahrain by a bacterial consortium (termed as AK6) under different bioprocess conditions. Biodegradation of petroleum hydrocarbons in oily sludge (C11-C29) increased from 24% after two days to 99% after 9 days of incubation in cultures containing 5% (w/v) of oily sludge at 40°C. When the nitrogen source was excluded from the batch cultures, hydrocarbon biodegradation dropped to 45% within 7 days. The hydrocarbon biodegradation decreased also by increasing the salinity to 3% and the temperature above 40°C. AK6 tolerated up to 50% (w/v) oily sludge and degraded 60% of the dichloromethane-extractable oil fraction. Illumina-MiSeq analyses revealed that the AK6 consortium was mainly composed of Gammaproteobacteria (ca. 98% of total sequences), with most sequences belonging to Klebsiella (77.6% of total sequences), Enterobacter (16.7%) and Salmonella (5%). Prominent shifts in the bacterial composition of the consortium were observed when the temperature and initial sludge concentration increased, and the nitrogen source was excluded, favoring sequences belonging to Pseudomonas and Stenotrophomonas. The AK6 consortium is endowed with a strong oily sludge tolerance and biodegradation capability under different bioprocess conditions, where Pseudomonas spp. appear to be crucial for hydrocarbon biodegradation.

“…In this study, the petroleum refinery sludge (PRS) was collected from Indian oil corporation limited Haldia, West Bengal, India. The PRS sample was stored in a closed container at 4 ℃ to avoid volatilization and to avoid any light exposure (Behera et al 2020). The process of PRS collection and the physicochemical properties of the sample has been reported in the earlier study (Behera et al 2020).…”

This research work demonstrated the comparative study of the efficacy of poultry litter extract (PLE) and inorganic fertilizer (NPK) as biostimulating agents for enhancing total petroleum hydrocarbon (TPH) degradation of petroleum refinery sludge (PRS) with bioaugmentation of an indigenously developed bacterial consortium. In this study, six sets of treatments such as natural attenuation, bioaugmentation with the indigenously developed bacterial consortium, and various biostimulation strategies with (MSM100, PLE100, NPK100, MSM50+PLE50, and MSM50+NPK50) were performed to meet 100% nutrient source for bacterial growth to enhance TPH degradation. Among all, the combined sources of MSM50+PLE50 showed the best performance by degrading the TPH up to 91.3 ± 4.1% within 28 d of the incubation period. The GC-FID analysis confirmed the efficacy of TPH degradation of PRS when PLE amendment with MSM. Further, the removal of maltene and asphaltene was also achieved 92 ± 3.7% and 52 ± 2.2% during this treatment. TPH degradation fitted to first-order kinetics with a rate constant 0.09 d-1 and half-life period of 7.7 d for MSM50+PLE50 amendment treatment along with bacterial consortium as bioaugmentation. This study revealed the implementation of the PLE amendment not only preferred as a nutrient source for bacterial growth but also enhanced TPH biodegradation in an eco-friendly strategic way by dropping the practice of inorganic salts.
