“…Surprisingly, the no-antibiotic azide treatment resulted in the highest methane production rate, consistently 15.8% greater than its corresponding no-azide surrogate. While it is common practice to use sodium azide for establishing sterile microbiological conditions, there have been several studies reporting the limited efficacy of azide addition within environmental matrices such as anaerobic swine manure (Kolz et al, 2005a), soil-manure slurries (Ingerslev and Halling-Sorensen, 2001), and soil-organic contaminant systems (Baek et al, 2003;Chefetz et al, 2006;Goel et al, 2003;Ro et al, 1995). In particular, the findings by Baek et al (2003) regarding the insensitivity of gram-positive bacteria and their associated periplasmic bound nitrate reductase, appears relevant to our results.…”

“…Freundlich coefficients presented here are given to indicate that our sorption results can be modeled using the Freundlich equation, and to provide a relative comparison between our data and previous studies. However, as discussed in Bowman (1981) and elsewhere (Chen et al 1999;Gunasekara and Xing 2003;Chefetz et al 2006), it is not possible to directly compare K f values when values of N are not equal.…”

Veterinary antibiotic sorption to agroforestry buffer, grass buffer and cropland soils

et al. 2010

The potential of veterinary antibiotics (VAs) to impact human and environmental health requires the development and evaluation of land management practices that mitigate VA loss from manuretreated agroecosystems. Vegetative buffer strips (VBS) are postulated to be one management tool that can reduce VA transport to surface water resources. The objectives of this study were to (1) investigate oxytetracycline (OTC) and sulfadimethoxine (SDT) sorption to agroforestry buffer, grass buffer, and cropland soils, (2) evaluate differences in VA sorption to soils collected from different vegetative management and soil series, and (3) elucidate relationships between soil properties and VA sorption. Sorption/extraction isotherms for OTC were well-fitted by the Freundlich isotherm model (r 2 [ 0.86). OTC was strongly adsorbed by all soils and the VA was not readily extractable. OTC and SDT solid to solution partition coefficients (K d ) values are significantly greater for soils planted to VBS relative to grain crops. Significant differences in OTC and SDT K d values were also noted among the soil series studied. Linear regression analyses indicate that clay content and pH were the most important soil properties controlling OTC and SDT adsorption, respectively. Results from this study suggest that agroforestry and grass buffer strips may effectively mitigate antibiotic loss from agroecosystems, in part, due to enhanced antibiotic sorption properties.

“…The microbial activity was controlled by the addition of 0.01 mol L −1 NaN 3 as a bacterial inhibitor. Sodium azide is one of the most common compounds used to inhibit microbial activity (Maagd et al, 1998; Goel et al, 2003; Chefetz et al, 2006 and references therein). The azide ion, N 3 − , is a powerful reducing agent (E 0 = −3.1 V), which indicates that thermodynamically it would be completely consumed (producing nitrogen gas) (Lide, 2004) while reducing iron (III) to iron (II), sulfate to sulfite/sulfide, etc.…”

The release of trace metals (Mn, Ni, Co, Cu, Zn, Pb, and Cd) and inorganic compounds (As) from initially anoxic Trepangier Bayou sediments, Louisiana and the sources of the released metals were investigated. After 1 to 2 d aeration, significant amounts of trace metals (Mn, Zn, Cd, Ni, and Co) were released to the aqueous phase with increased acidity, primarily due to the oxidation of acid-volatile sulfide and ferrous iron and iron sulfide minerals. The addition of a bacterial inhibitor, NaN,, to the Trepangier sediment during resuspension inhibited metal release, suggesting that microbial catalysis can regulate metal mobilization during sediment resuspension. In a well buffered system, oxidation of iron sulfides alone did not appear to induce trace metal release. Moreover, when Trepangier sediment was resuspended in anoxic conditions at neutral pH, <1% of the trace metal content was released, whereas a significant release of metal was observed under acidic anoxic conditions. Although oxidation of iron sulfide minerals is an essential prerequisite for the release of Zn, Co, Cd, and Ni, carbonates and oxides also play a role. The trace metals and inorganic compounds investigated could be classified into three groups according to their release characteristics: (i) Mn, Zn, Cd, Ni, and Co; (ii) Fe, Pb, and As; and (iii) Cu. The groupings appeared to depend on the sources of compounds and their relative affinity, after oxidation, to iron oxyhydroxides or organic matter.
