“…NPEO x and its derivative degrading bacterial strains have been isolated from several natural environments and wastewater treatment plants [1, 5, 21, 30, 57–59]. In this paper the reported data indicated that indigenous bacterial strains, isolated from soil, are able to use NPEO 15 as the sole carbon source.…”

Polyethoxylated nonylphenols, with different ethoxylation degrees (NPEOx), are incorporated into many commercial and industrial products such as detergents, domestic disinfectants, emulsifiers, cosmetics, and pesticides. However, the toxic effects exerted by their degradation products, which are persistent in natural environments, have been demonstrated in several animal and invertebrate aquatic species. Therefore, it seems appropriate to look for indigenous bacteria capable of degrading native NPEOx and its derivatives. In this paper, the isolation of five bacterial strains, capable of using NPEO15, as unique carbon source, is described. The most efficient NPEO15 degrader bacterial strains were identified as Pseudomonas fluorescens (strain Yas2) and Klebsiella pneumoniae (strain Yas1). Maximal growth rates were reached at pH 8, 27°C in a 5% NPEO15 medium. The NPEO15 degradation extension, followed by viscometry assays, reached 65% after 54.5 h and 134 h incubation times, while the COD values decreased by 95% and 85% after 24 h for the Yas1 and Yas2 systems, respectively. The BOD was reduced by 99% and 99.9% levels in 24 h and 48 h incubations. The viscosity data indicated that the NPEO15 biodegradation by Yas2 follows first-order kinetics. Kinetic rate constant (k) and half life time (τ) for this biotransformation were estimated to be 0.0072 h−1 and 96.3 h, respectively.

“…The same steps were followed in the effect of temperature, but the temperature was fixed at 37 ° C, with different concentrations (0.5, 1, 1.5, 2 & 3%) of crude oil incubated at 37 °C in a shaker incubator of 150 rpm for 12 days. After the incubation period, the biodegradation of the crude oil for both control and bacterial isolates was determined by spectrophotometry at 600 nm wavelength (Gupta, 2012).…”

In this study, the ability of bacteria presents in soils contaminated with crude oil to degrade petroleum hydrocarbons at the study sites (Al-Fatha and AL-Qayyarah) is investigated. Ten bacterial isolates are isolated from the soils of the study area, collected from different areas of Al-Fatha near the North Refineries in Salah-Din Governorate and AL-Qayyarah Refinery in Nineveh Governorate. These bacterial isolates show uneven growth in the mineral medium prepared with crude oil. Three new bacterial genera and two species are obtained, one of which belongs to the genus Bacillus and the other to the genus Exiguobacterium. The new bacterial isolates are recorded in the National Center for Biotechnology Information (NCBI) for the first time with the following numbers:(LC596402, LC596403& LC596406) for the genus (AM-I-1, AM-I- 2, and AM-I-5), respectively and (LC596404, LC596405) for the species (AM-I-3 and AM-I-4), respectively. The results show the ability of the isolates (AM-I-1, AM-I-2, AM-I-3, AM-I-4, and AM-I-5) to consume Polyaromatic Hydrocarbons (PAHs) compounds in the mineral medium prepared with crude oil with different concentrations and degrees, temperatures and pH conditions. The optimum conditions are pH 7, temperature 40°C and 2% crude oil concentration with a period of 12 days. The bacteria (AM-I-3) has outperformed the rest of the bacterial isolates with a consumption of (PAHs) compounds of 86.5%, followed by bacterial isolates and their mixture with a consumption rate of (84.42%, 78.19%, and 75.20%) (AM-I-1, AM-I-4, & mix of isolates), respectively.

Polluted sites often contain both heavy metals and organic xenobiotic contaminants. This warrants the use of either a great number of bacterial degraders or bacteria having the ability to detoxify several toxicants simultaneously. In this research, the ability of a molybdenum-reducing (Mo-reducing) bacterium isolated from contaminated soil to decolorize various phenolics independent of Mo reduction was screened. Studies showed that this bacterium was able to grow on 4-nonylphenol and reduced molybdate to Mo-blue. The optimal condition for this activity was pH between 6.3 and 6.8 and temperature of 34EC. Glucose proved to be the best electron donor for supporting molybdate reduction followed by galactose, fructose, and citrate in descending order. Other requirements included a phosphate concentration between 2.5 mM and 7.5 mM and a molybdate concentration between 20 and 30 mM. The absorption spectrum of the Mo-blue produced was similar to numerous previously described Mo-reducing bacteria, closely resembling a spectrum of the reduced phosphomolybdate. Mo reduction was inhibited by mercury (II), silver (I), copper (II), cadmium (II), and chromium (VI) at 2 ppm by 79.6%, 64.2%, 51.3%, 28.1%, and 25.0%, respectively. The biochemical analysis resulted in a tentative identification of the bacterium as Pseudomonas aeruginosa strain Amr-11. The ability of this bacterium to detoxify Mo and grow on nonylphenol makes this bacterium an important tool for bioremediation.
