“…UCC 0009, full degradation of phenol at initial concentrations of 1800-2100 mg L −1 required more than 12 days (Nawawi et al 2017), whereas our R. aetherivorans UCM Ac-602 achieved full phenol assimilation at an initial concentration of 1750 mg L −1 after only 4 days. The best phenol degrading performance in terms of highest initial phenol concentrations of 2500 and 2600 mg L −1 was recorded for Acinetobacter lowffii UW7 with 61.1% degradation after 3 days (Liu et al 2011) and Pseudomonas aeruginosa NIBGE MB with 100% degradation after 7 days (Afzal et al 2007) (Table 3). The phenol-assimilating activity of freely-suspended cells of our R. aetherivorans UCM Ac-602 was limited by an initial phenol concentration of 2000 mg L −1 , although the cells remained viable over 6 days cultivation.…”

Microbe-based decontamination of phenol-polluted environments has significant advantages over physical and chemical approaches by being relatively cheaper and ensuring complete phenol degradation. There is a need to search for commercially prospective bacterial strains that are resistant to phenol and other co-pollutants, e.g. oil hydrocarbons, in contaminated environments, and able to carry out efficient phenol biodegradation at a variable range of concentrations. This research characterizes the phenol-biodegrading ability of a new actinobacteria strain isolated from a lubricant-contaminated soil environment. Phenotypic and phylogenetic analyses showed that the novel strain UCM Ac-603 belonged to the species Rhodococcus aetherivorans, and phenol degrading ability was quantitatively characterized for the first time. R. aetherivorans UCM Ac-603 tolerated and assimilated phenol (100% of supplied concentration) and various hydrocarbons (56.2–94.4%) as sole carbon sources. Additional nutrient supplementation was not required for degradation and this organism could grow at a phenol concentration of 500 mg L−1 without inhibition. Complete phenol assimilation occurred after 4 days at an initial concentration of 1750 mg L−1 for freely-suspended cells and at 2000 mg L−1 for vermiculite-immobilized cells: 99.9% assimilation of phenol was possible from a total concentration of 3000 mg L−1 supplied at daily fractional phenol additions of 750 mg L−1 over 4 days. In terms of phenol degradation rates, R. aetherivorans UCM Ac-602 showed efficient phenol degradation over a wide range of initial concentrations with the rates (e.g. 35.7 mg L−1 h−1 at 500 mg L−1 phenol, and 18.2 mg L−1 h−1 at 1750 mg L−1 phenol) significantly exceeding (1.2–5 times) reported data for almost all other phenol-assimilating bacteria. Such efficient phenol degradation ability compared to currently known strains and other beneficial characteristics of R. aetherivorans UCM Ac-602 suggest it is a promising candidate for bioremediation of phenol-contaminated environments.

And Guosheng Liu [7]find Acinetobacter lwoffii is good to treat high concentration of phenol wastewater. These strains were found in wastewater had ability to degraded phenols and polycyclic aromatic hydrocarbons, also verified the principle of removing organic pollutants.…”

In order to provide an effective and economic method for the yeast wastewater′s treatment, this study taken yeast wastewater as objection, and applied immobilized micro-aerobic microorganism technology into yeast wastewater′s treatment, then explored the degradation effect of major pollutants in yeast wastewater. The immobilized carrier was analyzed by scanning electron microscope (SEM) and Fourier transform infrared spectrometer (FTIR), and dominant species in immobilized carrier were identified. The results showed that immobilized carrier was a composite carrier with porous structure, and removal rate of chemical oxygen demand (COD), ammonia nitrogen (NH3-N), total nitrogen (TN) and total organic carbon (TOC) of yeast wastewater by using the immobilized micro-aerobic microorganism technology were 71.1%, 99.7%, 61.4% and 67.0%, respectively. Moreover, the dominant bacteria which attached in the carrier included Sphingomonaspaucimobilis, Pseudomonas putida, Acinetobacterlwoffii and Pseudomonas stutzeri.

This article provides an overview about the microbes selecting, types of bioreactors, the treatment condition, etc. which influence the odors abatement effect. In the recent past, many highly efficiency microorganisms on the actual governance of malodorous gases have been selected and trained. Among different bioreactor configurations, biofilters, biotrickling filters and bioscrubbers are most common ones. The membrane bioreactor and the three phase fluidised bed bioreactor as new bioreactors have broad development prospects. Finally, this review also provides how to insights into future R&D needs in this area.
