Two-liquid-phase mesophilic and thermophilic biotrickling filters for the biodegradation of α-pinene

Antioxidative, anticancer and genotoxic properties of α-pinene on N2a neuroblastoma cells

“…α-Pinene has high potential for human exposure since it was applied in various industries, such as pulp and paper industry, forest production, pharmaceutical industry, food industry, colour printing and paint process (Linares et al 2009;Montes et al 2010;Rene et al 2010;Wu et al 2012). In the current study, we evaluated the antiproliferative effects of α-pinene on both cultured primary rat neurons and N2a NB cells via the MTT assay for the first time.…”

Mesophilic and thermophilic biofiltration of gaseous toluene in a long-term operation: Performance evaluation, biomass accumulation, mass balance analysis and isolation identification

“…spry paint) and waste treatment (i.e. dry activated sludge cake) frequently demonstrate high temperatures (40-70 • C), which is higher than the temperature ranges corresponding to the optimum activity of mesophilic microorganisms [7,8]. One option for the treatment of high temperature gases is cooling these exhausts below 40 • C prior to biological reactors, which is quite expensive [9].…”

Novel Bioreactors for Waste Gas Treatment

“…It is important to add only low amounts of organic phase to the system, since that additional phase will also result in an additional cost. A recent study has shown that the addition of only 5% silicone oil to the recirculating medium can easily increase the performance of mesophilic and thermophilic biotrickling fi lters for the removal of a -pinene in gas-phase (Montes et al 2010 ) .…”

“…In order to overcome mass transfer constraints, the addition of a water-immiscible organic solvent, such as silicone oil, oleyl alcohol, decane, n-hexadecane, dodecane, diethyl sebacate, 1-octadecane, isopropyl myristate, 2-undecanone, has been suggested (Daugulis 1997(Daugulis , 2001Kennes and Veiga 2001 ;Muñoz et al 2006 ;Mahanty et al 2008 ;Fazaelipoor 2009 ;Bailón et al 2009 ;Kennes et al 2009a ;Montes et al 2009Montes et al , 2010 . Silicone oil, commercially known as polydimethylsiloxane [(H 3 C) [SiO(CH 3 ) 2 ] n Si(CH 3 )], has shown to serve the intended purpose by its addition in waste-gas treatment systems.…”
