“…Phenol degradation results show typical substrate inhibition phenomena especially at high phenol concentrations as well at low temperature. Although this is the first reporting of low temperature biodegradation study for R. glutinis, similar behavior are also reported for other yeast species in the literature [13][14][15][16][17][18][19]. Glucose concentrations used in this study are significantly lower than the studies which used Rhodotorula glutinis for industrial purposes (e.g.…”

“…Furthermore, little is known about the biodegradability of phenol by yeasts at colder temperatures [13,14] which is more significant for in-situ applications, compared to mesophilic temperatures [15]. Phenol is a well-known and used disinfectant therefore the species that can biodegrade phenol (especially at high concentrations) are limited since it inhibits the microbial growth [16].…”

Biotoxicity and low temperature are among the challenges of biodegradation as well as microbial transport in in-situ bioremediation applications. This study investigates the effect of low temperature, high and low concentrations of phenol, on biodegradability and the surface properties of Rhodotorula glutinis which may be instrumental to develop control mechanisms in engineering applications. Results showed that Rhodotorula glutinis is able to grow at low phenol (< 0.5 g/L) and glucose (1.0 g/L) concentrations. Microbial growth rates of Rhodotorula glutinis is the highest at 25°C for phenol fed reactors. Temperature and type of carbon source affected the total amount of extracellular polymeric substances (EPS) and the relative amounts of EPS constituents. Phenol fed Rhodotorula glutinis, at 4°C, were found to be hydrophobic whereas Rhodotorula glutinis showed less hydrophobic characteristics at 25°C, regardless of the carbon source. Surface hydrophobicity of Rhodotorula glutinis is related to the distribution of carbohydrate and proteins in the EPS.

“…The capability of alkane degradation is often attributed to their ability of biosurfactants production (Ganesh and Lin, 2009). Margesin et al (2013) also reported most efficient n-alkane degraders belonged to genus Rhodococcus that were able to deplete C12eC22, with the best efficiency for C12eC18.…”

a b s t r a c tThis research is part of a multidisciplinary research program to develop a bioremediation protocol for a solid waste management (SWM) site in Northern California -a site which is heavily contaminated with petroleum hydrocarbons. In this initial study, 30 bacterial strains were isolated and evaluated for their efficiencies to deplete crude oil. The 3 most efficient bacterial isolates for crude oil depletion were designated as S1BD1, OPKDS2, and OSDS1; they were identified as Serratia proteamaculans, Alcaligenes sp. and Rhodococcus erythropolis, respectively, based on partial 16S rRNA gene sequences. Determination of crude oil depletion efficiency by gas chromatographyemass spectrometry (GC-MS) revealed that Serratia proteamaculans S1BD1 was the most efficient (68.0 ± 1.78%), followed by Alcaligenes sp. OPKDS2 (63.7 ± 3.28%), and Rhodococcus erythropolis OSDS1 (54.9 ± 5.07%). S. proteamaculans S1BD1 was able to deplete a wide spectrum of carbon compounds within the individual components of crude oil. Alcaligenes sp. OPKDS2 was the most efficient at depleting BTEX (91.2 ± 1.90%), and R. erythropolis OSDS1 exhibited a substrate preference of n-alkanes. All three strains exhibited unusually high crude oil depletion efficiencies and tolerated a wide range of salinity and pH levels, which makes them excellent candidates for bioaugmentation of the SWM site.

“…Compared with physical and chemical methods, bioremediation d using organisms to remove and degrade crude oil d is recognized as more economical, efficient and environmentally friendly (Margesin et al, 2013;McGenity, 2014;Wang et al, 2011a,b). As degraders, numerous microorganisms that utilize crude oil as their carbon source have been isolated, such as Acinetobacter (Lin et al, 2014), Pseudomonas (Zhang et al, 2011), Rhodococcus (Van Hamme andWard, 2001) and Alcanivorax (Liu et al, 2010).…”

a b s t r a c tA bacterial strain, CN-3, was isolated from petroleum-contaminated sediment in Bohai Bay, China. Morphological, physiological and phylogenetic analyses indicated that the strain belonged to the genus Dietzia. It was capable of utilizing a wide range of alkanes (C 14 eC 31 ), aromatic compounds and crude oil as the sole carbon and energy sources. The bacterium showed high degradation rate (>80%) of the saturated hydrocarbons of crude oil in the pH range of 6e9. The degradation rate was hardly affected at a NaCl concentration up to 85 g L À1 , indicating that the strain can tolerate high salinities. The real-time quantitative Polymerase Chain Reaction (PCR) results showed that the CYP153 genes could be significantly induced by C 14 , C 15 , C 16 , C 26 and pristane, whereas the transcription level of alkB gene was increased moderately with C 14 , C 15 , C 16 , C 26 and pristane induction condition. A high degradation extent, wide substrate range and facile conditions enhanced the potential for this bacterial strain to be used in the bioremediation of crude oil pollution.
