“…With the increase of the incubation time (340 d), biodegradation percentages gradually increased from 20.40% to 60.62% for Phen and from 15.55% to 49.21% for Pyr, and the stored-PAHs in the fungal bodies gradually decreased by 5.89% for Phen and by 15.18% for Pyr at 40-d, which suggested that PAHs both in solution and fungal body can be biodegraded. The degradation process is consistent with the biosorption behavior of fungal body, which was controlled by partition and the process of sorption-desorption was reversible [15,22].…”

“…The biosorption of Phen and Pyr by heat-killed mycelial pellets reached apparent equilibrium within 3 d, and 40.23%± 0.11% of Phen and 74.71%±0.60% of Pyr were removed from solution. It is reported that biosorption mechanism of nonpolar organic pollutants by dead biomass is partition [15,22]. The respective partition coefficients of phenanthrene and pyrene are 4040 and 17500 L/kg.…”

“…In the process of bioremediation, microorganisms can be viewed both as a bio-sorbent that accommodates organic pollutants and as a bioreactor that degrades them [15]. Biosorption is a physic-chemical process involved in the sorption of a chemical substance in/on a biological matrix/ surface [16,17].…”

“…Ding et al [22] reported that the biosorption mechanism of phenanthrene and pyrene by dead white-rot fungi was dominated by partition into fungal bio-mass and biosorption-desorption was reversible. Most studies about bioremediation are focused on biodegradation of organic pollutants; however, the biosorption of soil indigenous microbial body and their impact on biodegradation are still unknown, because it is difficult to distinguish biosorption of microbial body and sorption of soil in the complex system [15]. Recently, the influences of biosorption and biodegradation on the transport, fate and pollution control of POPs in the environment have been increasingly concerned.…”

“…Stringfellow and Alvarez-Cohen [23] suggested that biosorption can decrease the rate of polycyclic aromatic hydrocarbons (PAHs) biodegradation in short term, and contributed to the immediate removal of PAHs from polluted solution. Chen et al [15] quantitatively described the contribution of biosorption and biodegradation to the total bio-dissipation of PAHs, and suggested that the ratio of apparent partition coefficients in live fungal systems (K d * ) to the partition coefficient of heat-killed fungi (K d ) can be employed to illustrate the relative contributions of biosorption and biodegradation under different nutrient conditions. Biosorption reduced biodegradation percentage, while nitrogen limitation and co-existing of PAHs improved biodegradation.…”

Biosorption and biodegradation of phenanthrene and pyrene by live and heat-killed Phanerochaete chrysosporium are investigated to elucidate the bio-dissipation mechanisms of polycyclic aromatic hydrocarbons (PAHs) in aqueous solution and its regulating factors. The effects of nutrient conditions (carbon source and nitrogen source concentrations), the co-existing Cu 2+ , and repeated-batch feed of PAHs on the biosorption and biodegradation are systematically studied. The removal of PAHs by dead bodies of P. chrysosporium is attributed to biosorption only, and the respective partition coefficients of phenanthrene and pyrene are 4040 and 17500 L/kg. Both biosorption and biodegradation contribute to the dissipation of PAHs by live P. chrysosporium in water. After a 3-d incubation, the removal percentage via biosorption are 19.71% and 52.21% for phenanthrene and pyrene, respectively. With the increase of the incubation time (340 d), biodegradation gradually increases from 20.40% to 60.62% for phenanthrene, and from 15.55% to 49.21% for pyrene. Correspondingly, the stored-PAHs in the fungal bodies decrease. Under the carbon-rich and nitrogen-limit nutrient conditions, the removal efficiency and biodegradation of phenanthrene and pyrene are significantly promoted, i.e. 99.55% and 92.77% for phenanthrene, and 99.47% and 83.97% for pyrene after a 60-d incubation. This phenomenon is ascribed to enhanced-biosorption due to the increase of fungal biomass under carbon-rich condition, and to stimulated-biodegradation under nitrogen-limit condition. For the repeated-batch feed of phenanthrene, the pollutant is continuously removed by live P. chrysosporium, and the contribution of biodegradation is enhanced with the repeated cycles. After 3 cycles, the biodegradation percentage is up to 90% with each cycle of a 6-d incubation.biosorption, biodegradation, Phanerochaete chrysosporium, polycyclic aromatic hydrocarbons, bioremediation Citation:Ding J, Chen B L, Zhu L Z.

Phenanthrene Removal from Aqueous Solution on Sesame Stalk‐based Carbon

This work explored the performance of sesame stalk-based carbon prepared at different carbonization temperatures and activated by potassium hydroxide in the removal of phenanthrene from an aqueous solution. At a carbon concentration of 10 mg/32 mL and a carbonization temperature of 7008C, the removal efficiency of phenanthrene approached 100%. Furthermore, with the presence of acenaphthene and naphthalene as co-contaminants, the removal efficiency of phenanthrene by the prepared carbon was 99.60%, which was comparable to that by the commercial carbon. Hydrophobic interactions influenced phenanthrene removal, and partitioning appeared to be the dominant mechanism for phenanthrene removal from aqueous solution by sesame stalk-based carbon. The results obtained from this work should provide insight into the reuse of agricultural residues, and also suggest a new avenue for the removal of polycyclic aromatic hydrocarbons from contaminated water utilizing carbon prepared from agricultural residue.

BACKROUND: In Izmir, Turkey, wastewaters from the petrochemical industry are treated using conventional activated sludge systems. A significant proportion of poly-aromatic hydrocarbons (PAHs) with high-molecular weights remains in this treatment system and inhibits the biological activity. Biosurfactants increase PAHs degradation by enhancing the solubility of the petroleum components. The aerobic inhibition kinetics of PAHs has not previously been investigated in the presence of biosurfactants for a real petrochemical industry wastewater. RESULTS: Among the kinetic models used (Monod-type, zero, first-order and second-order) it was found that the Monod kinetic was effective for describing the biodegradation of PAHs in petrochemcal industry wastewater in the presence of three biosurfactants, namely Rhamnolipid (RD), Surfactine (SR) and Emulsan (EM) in an aerobic activated sludge reactor (AASR). The maximum PAH removal rate (R max ) and specific growth rate of PAH degrading bacteria (µ max ) increased, while the half saturation concentration of PAH (K
