“…The genera Bacillus , Stenotrophomonas , Microbacterium , Pseudoxanthomonas , Ochrobactrum , and Flavobacterium were also identified, with each of them occurring as either a single isolate or two isolates and clustering into a single OTU. Each of these genera of isolates have previously been associated with PAH degradation in different environmental matrices [ 14 , 35 , 36 ]. This study reported culturable PAH-degrading bacteria isolates.…”

Restoration of polycyclic aromatic hydrocarbon- (PAH-) polluted sites is presently a major challenge in agroforestry. Consequently, microorganisms with PAH-degradation ability and soil fertility improvement attributes are sought after in order to achieve sustainable remediation of polluted sites. This study isolated PAH-degrading bacteria from enriched cultures of spent automobile engine-oil polluted soil. Isolates' partial 16S rRNA genes were sequenced and taxonomically classified. Isolates were further screened for their soil fertility attributes such as phosphate solubilization, atmospheric nitrogen fixation, and indoleacetic acid (IAA) production. A total of 44 isolates were obtained and belong to the genera Acinetobacter, Arthrobacter, Bacillus, Flavobacterium, Microbacterium, Ochrobactrum, Pseudomonas, Pseudoxanthomonas, Rhodococcus, and Stenotrophomonas. Data analysed by principal component analysis showed the Bacillus and Ochrobactrum isolates displayed outstanding IAA production. Generalized linear modelling statistical approaches were applied to evaluate the contribution of the four most represented genera (Pseudomonas, Acinetobacter, Arthrobacter, and Rhodococcus) to soil fertility. The Pseudomonas isolates were the most promising in all three soil fertility enhancement traits evaluated and all isolates showed potential for one or more of the attributes evaluated. These findings demonstrate a clear potential of the isolates to participate in restorative bioremediation of polluted soil, which will enhance sustainable agricultural production and environmental protection.

“…Total petroleum hydrocarbons (TPHs), defined as a mixture of aromatic and aliphatic hydrocarbons coming from crude oil products used in industry and transportation, can be both toxic for soil microorganisms as well as beneficial as a carbon source (Maliszewska-Kordybach 2003 ; Sutton et al 2013 ). Some soil bacteria, i.e., Pseudomonas genus, are known to effectively degrade the hydrocarbons and are used in oil-polluted soil bioremediation (Pacwa-Płociniczak et al 2014 ; de la Cueva et al 2016 ).…”

Various inorganic and organic pollutants in industrial soils may adversely affect soil microorganisms and terrestrial ecosystem functioning. The aim of the study was to explore the relationship between the microbial activity, microbial biomass, and functional diversity of soil bacteria and the metals and total petroleum hydrocarbons (TPHs) in the Upper Silesian Industrial Region (Poland). We collected soil samples in pine-dominated forest stands and analyzed them according to a range of soil physicochemical properties, including metal content (cadmium, lead, and zinc) and TPH content. Metal concentrations were normalized to their toxicity to soil microorganisms and integrated in a toxicity index (TI). Soil microbial activity measured as soil respiration rate, microbial biomass measured as substrate-induced respiration rate, and the bacterial catabolic activity (area under the curve, AUC) assessed using Biolog® ECO plates were negatively related to TPH pollution as shown in multiple regressions. The canonical correspondence analysis (CCA) showed that both TPH and TI affected the community-level physiological profiles (CLPPs) of soil bacteria and the pollutants’ effects were much stronger than the effects of other soil properties, including nutrient content.Electronic supplementary materialThe online version of this article (doi:10.1007/s11270-016-2966-0) contains supplementary material, which is available to authorized users.

“…This result indicates that these two strains present different genetic attributes involved in hydrocarbon degradation or different adaptability to the soil used in the experiment. Cueva et al (2016) also found an increased species richness and abundance of the genus Acinetobacter during the bioremediation of a hydrocarbons-contaminated soil. According to these authors, some species of this genus have the ability to use straight-chain alkanes as carbon and energy sources owing to the presence of the genes alkM, Ruba, Rubb, alkR, and xcpR in their genome, whose products act as regulators of hydrocarbon metabolism (Decorosi, Mengoni, Baldi, & Fani, 2006).…”

“…The correlation between TPH biodegradation and microbial populations' dynamics helps to explain long-term bioremediation process, which may contribute to increase bioremediation efficiency in soils exposed to recurrent contamination (Cueva, Rodríguez, Cruz, Contreras, & Miranda, 2016). According to Kaplan and Kitts (2004), specific bacteria are associated with different stages of hydrocarbon biodegradation in soils.…”

The effect of successive soil contamination with diesel oil was evaluated on population dynamics of a bacterial consortium (Acinetobacter baumannii LBBMA 04, Pseudomonas aeruginosa LBBMA 58, Ochrobactrum anthropi LBBMA 88b, Acinetobacter baumannii LBBMAES11, and Bacillus subtilis LBBMA 155) and on biodegradation of petroleum hydrocarbons (n-C12-C22). After each contamination with diesel oil, soil samples were collected for assessment of bacterial population and sequence of petroleum hydrocarbons degradation. At 20 and 40 days, the highest percentage of degradation was observed for the higher carbon chain hydrocarbons (n-C21 and C22). After the third contamination, there was a considerable reduction of n-C21degradation and a high degradation of hydrocarbons n-C13-15, C17 and C19, which contrasts with the low values of degradation of these hydrocarbons in the two previous phases. The highest growth rate of all members of the consortium occurred from 0 to 20 days, but population increase continued up to the end of the experiment (except for B. subitillis strain, whose population stabilized after 20 days). Our results show that the recurrent contamination by hydrocarbons affected the population structure of bacterial consortium and increased the total population density of the bacterial consortium.
