Phase partition of gaseous hexane and surface hydrophobicity of Fusarium solani when grown in liquid and solid media with hexanol and hexane

Elimination of hydrophobic volatile organic compounds in fungal biofilters: Reducing start‐up time using different carbon sources

“…In experiments B2, B3, and B4, n-hexane feed was initiated when the fungus had entered the stationary phase as seen by the CO 2 production. This strategy was followed after preliminary tests showed that the presence of a more available substrate inhibited the uptake of n-hexane (Vergara-Fernández et al (2006). To evaluate the influence of n-hexane load, different concentrations of n-hexane between 0.5 and 12 g m À3 were tested, maintaining for 3 days a constant gas flow rate.…”

“…However, this obstacle may be reduced using fungi as the biological agent (Davison et al, 2000;Kennes and Veiga, 2004;Vergara-Fernández et al, 2006). Fungi have several advantages for the abatement of hydrophobic volatile organic compounds (VOC) in gas phase biofilters including their ability to degrade a large number of VOCs (Qi et al, 2002), their resistance to low humidity and pH, their capacity to colonize unoccupied space with the aerial hyphae and to penetrate the solid support increasing the availability of nutrients.…”

Biological treatment of contaminated air with toluene in an airlift reactor

“…This increase in the biomass concentration creates a greater bioavailability of toluene. The increase in bioavailability of toluene is generated by reducing the partition coefficient in the liquid phase (greater solubility), produced by the presence of proteins, lipoproteins and the same biomass that is generated, generating a change in medium hydrophobicity, according to Vergara-Fernández et al (2006) and Davison et al (2000). This suggests that it is possible to eliminate greater quantities of toluene by increasing the concentration of suspended biomass in the reactor.…”

Production of Valuable Lipophilic Compounds by Using Three Types of Interface Bioprocesses: Solid–Liquid Interface Bioreactor, Liquid–Liquid Interface Bioreactor, and Extractive Liquid-Surface Immobilization System

“…The same phenomenon was also confirmed in cells that adhered onto the surface of hydrophobic synthetic polymers such as styrene-divinylbenzene copolymer and polytetrafluoroethylene 97 . It was reported that the growth rate of Staphylococcus epidermidis and Pseudomonas aeruginosa 98 , the cell surface hydrophobicity of Fusarium solani 99 , and the morphology of Cylindrocarpon and Acremonium cells 100 were significantly affected by the adhesion onto hydrophobic solid surfaces. In addition to the phenomena described previously, researchers have found that the subterminal hydroxylation activity of Monilliera sp.…”
