“…Moreover, when SA concentration ranged from 5 to 10 mM the heat flow curves showed two picks, as for a diauxic event (Braissant et al, 2013), suggesting a possible utilization of SA by P. fluorescens IMA 19/5. On the other hand, the ability of strains belonging to Pseudomonas spp, to degrade SA was already reported by other authors (Filonov et al, 2000;Kesseru et al, 2005).…”

“…Salicyclic acid has a strong EDG (-OH) and a moderate electron withdrawing group (EWG) (-COOH) (Supplementary data). The proposed pathways of salicyclic acid biodegradation under nitrate-reducing conditions were (1) via direct reduction of the aromatic ring, or (2) by reductive ortho-dehydroxylation(Bonting & Fuchs, 1996) Kesserű et al (2005). demonstrated the nitratedependent salicyclic acid degradation under anaerobic condition, in which nitrate reduction provides oxygen for the oxidation of salicylic acid (ring cleavage of catechol).…”

A pilot-scale study was conducted to investigate the fate of trace organic contaminants (TrOCs) during anaerobic digestion of primary sludge. Of the 44 TrOCs monitored, 24 were detected in all primary sludge samples. Phase distribution of TrOCs was correlated well with their hydrophobicity (>67% mass in the solid phase when LogD>1.5). The pilot-scale anaerobic digester achieved a steady performance with a specific methane yield of 0.39-0.92 L/gVS removed and methane composition of 63-65% despite considerable variation in the primary sludge. The fate of TrOCs in the aqueous and solid phases was governed by their physicochemical properties. Biotransformation was significant (>83%) for five TrOCs with logD<1.5 and electron donating functional groups in molecular structure. The remaining TrOCs with logD<1.5 were persistent and thus accumulated in the aqueous phase. Most TrOCs with logD>1.5 were poorly removed under anaerobic conditions. Sorption onto the solid phase appears to impede the biodegradation of these TrOCs.

The toxic and growth inhibiting effects of methyl tert-butyl ether (MTBE) on the hydrocarbon-degrading Pseudomonas veronii T1/1 strain (isolated from gasoline contaminated soil) were studied. In our experiments, the MIC of MTBE was found to be 60 mM and the EC 50 was 51.7 mM. In the concentration range 0-30 mM, MTBE did not significantly influence the growth parameters of this bacterium, but at concentrations over 30 mM MTBE exerted a significant growth inhibiting effect. In the presence of 70 mM MTBE, the specific growth rate dropped from 0.4731 to 0.1201 h -1 , while the length of the lag period increased from 5.41 to 17.01 h and the yield coefficient declined from 0.2652 to 0.0718 g g -1 . MTBE at 100 mM inhibited the growth of this strain completely. These findings may have important environmental implications, as high concentrations of MTBE could influence the efficiency of soil and groundwater bioremediation processes significantly.
