“…From all these studies a clear dose response relationship cannot be established. However, recent experiments showed a positive impact of the polypeptide antibiotic colistin sulfate on both cumulative biogas and methane production (Riemenschneider et al, 2014). In case of this study, no uniform pattern was observed which contradicts a general negative influence of the antibiotics investigated on the fermentation process.…”

“…Studies have shown the elimination of selected veterinary antibiotics during the anaerobic fermentation (Álvarez et al, 2010;Cetecioglu et al, 2013;Mitchell et al, 2013;Mohring et al, 2009;Riemenschneider et al, 2014). Thus, the process in biogas plants is discussed as potential sink for veterinary antibiotics.…”

“…Additionally, Li et al [ 42 ] used “recycled water derived from a beef farm.” Within one publication, lagoon sediment was mixed with water down to a dry matter content of 2.7 % [ 2 ]. Cetecioglu et al [ 14 ] and Angenent et al [ 4 ] took manure for transformation experiments out of a continuously running anaerobic sequencing batch reactor (ASBR), whereas Mohring et al [ 50 ] and Riemenschneider et al [ 57 ] took it directly out of a biogas plant.…”

The spread of veterinary medicinal products (VMPs) and biocides via manure onto agriculturally used areas represents a very important emission into the environment for these product groups. Within this literature study, publicly available transformation studies with liquid manure are summarized. Transformation studies were evaluated regarding the transformation fate of tested substances, the origin and characteristics of used manure, the experimental setup, and the measured parameters. As main topics within the 42 evaluated transformation studies, the high dependency of transformation on temperature, redox potential, dry matter content, and other parameters is reported. Test duration throughout the studies ranged from 2 to 374 days and study temperature ranged from 5 to 55 °C. Only seven publications gave information on the redox potential of the manure. Further, the characterization of the matrix in many cases was inadequate due to missing parameters such as dry matter content or pH. Only three publications studied transformation of biocides. To allow for a consistent assessment of studies within the registration process, a harmonized internationally accepted and validated test method is needed. Additionally, monitoring data of VMPs in manure were collected from literature and evaluated regarding the origin and characteristics of the manure, the minimum/maximum found concentrations, and the percentage of identified compounds. Within the 27 evaluated publications, 1568 manure samples were analyzed and 39 different active substances for VMPs and 11 metabolites and transformation products of VMPs could be found in manure. Most often, the samples were analyzed for sulfonamides, tetracyclines, and fluoroquinolones. Not one study searched for biocides or worked with a non-target approach. For sulfadiazine and chlortetracycline, concentrations exceeding the predicted environmental concentrations were found.

“…Among the enzyme classes mentioned, there are ureases (EC 3.5.1.5), catalases (EC 1.11.1.6), peroxidases (EC 1.11.1.7) and polyphenol oxidases (EC 1.10.3.1). These enzymes have high sensitivity to various exposures and perform important functions in the organic matter transformation which the N cycle depends on [11][12][13]. The urease activity is associated with urea ammonification and nitrogen conversion into the plant-available form.…”

Soil amendment with biochar has been proposed as a tool to mitigate soil N 2 O emissions by altering soil physical, chemical and biological properties. Little work has been focused on the effect of biochar on the soil enzymatic activity as the most sensitive indicator to diagnose the changes in soil quality. The 90-day laboratory experiment to study the effect of biochar on the dynamics of some soil enzymes and cumulative N 2 O emissions from the loamy sand Spodosol was conducted with the aim to justify the sensitiveness of the enzymes to soil amendments with biochar. The experimental setup was a randomized block design with 9 replicates and included the soil control (K), the soil with biochar (BC), the soil with mineral fertilizer (N 16 P 16 K 16 , N 90) and the soil with fertilizer and biochar mixture (N 90 + BC). The hydrolases (urease) and oxidoreductases (catalase, peroxidase and polyphenol oxidase) were selected due to their high sensitivity to the changes in the soil quality and the significance in the nitrogen cycle. The results of the experiment have shown that the soil amendment with 10 t/ha of biochar significantly (p < 0.05) reduced (1.4-fold) cumulative N 2 O emissions from the soil compared to the K and N 90 treatments. The presence of biochar in the soil had no significant effect on the urease activity, while activity of the catalase, peroxidase and polyphenol oxidase was significantly (p < 0.05) higher (1.2 times in average) due to the changes in the physical properties of the soil (aeration in particular). There was high positive correlation between N 2 O flux and catalase activity (r = 0.85 and 0.87 for BC and N 90 + BC, respectively). Based on the calculation of the humification coefficient (polyphenol oxidase activity to peroxidase activity) revealed that soil mineralization increased by 10-13 % after soil amendment with BC, compared to the treatments without BC. The soil amendment with biochar significantly changed the red-ox soil conditions. That was reflected in the changes of enzymatic activity, N 2 O emission and mineralization of humic substances. All the studied enzymes, except urease, were sensitive bio-indicators of soil conditions and could be used in the environment assessment methodology for land-use systems with biochar amendments.
