Antibiotic residues in substrates and output materials from biogas plants – Implications for agriculture

Effects of Ciprofloxacin Alone or in Mixture with Sulfamethoxazole on the Efficiency of Anaerobic Digestion and Its Microbial Community

“…The digestate remaining after AD treatment is commonly spread on the soil as a replacement for conventional mineral fertilizers. In the last decade, AD treatment has also been attracting interest for its potential to degrade some organic pollutants and emerging contaminants like pharmaceuticals commonly found in animal manure [ 5 , 6 ], although much research is needed to verify the effectiveness of the process. Veterinary antibiotics are widely used to treat and prevent animal diseases in husbandry practices.…”

“…Livestock manure is commonly applied to land as an organic fertilizer, and it is generally recognized that by adding it, antibiotic residues from treating cattle infections can be introduced into soils [ 12 , 13 ]. Sulfonamides, fluoroquinolones, tetracyclines and macrolides are the antibiotics most commonly used in veterinary practices [ 5 , 11 , 14 ]. Among them, ciprofloxacin (CIP) and sulfamethoxazole (SMX), belonging to the class of fluoroquinolones and sulfonamides, respectively, are the most frequently detected in manure and consequently in agroecosystems [ 15 , 16 , 17 ].…”

“…Among them, ciprofloxacin (CIP) and sulfamethoxazole (SMX), belonging to the class of fluoroquinolones and sulfonamides, respectively, are the most frequently detected in manure and consequently in agroecosystems [ 15 , 16 , 17 ]. CIP and SMX differ in their environmental mobility and persistence [ 5 ]. CIP shows a high persistence in soil and water [ 18 ] due to its recalcitrance to biodegradation [ 19 ] and high affinity for the soil matrix.…”

Nanocomposites of zirconia@activated carbon derived from a hazelnut shell for the adsorption of tetracyclines from water

“…2 The tetracycline antibiotics have often been detected in animal manures and farm wastewaters. 3 For example, Zhi et al 4 reported the high prevalence of CTC in pig manure (206.25 mg kg −1 ) and dairy farm wastewater (25.01 mg L −1 ). The untreated agricultural wastewater or excreted liquid manure from the production of livestock and poultry has become a major contamination source of antibiotics.…”

Combined Dairy Manure-Food Waste Digestate as a Medium for Pleurotus djamor—Mineral Composition in Substrate and Bioaccumulation of Elements in Fruiting Bodies

“…Among various agro-industrial wastes, the possible utilisation of original digestate (OD) derived from combined dairy manure-food waste can stand out due to the nutritional composition [35], easy availability [32] and relatively low price. On the other hand, depending on the input to the biogas digesters, the digestate can be rich in mineral elements such as nonessential elements, trace elements and heavy metals, various organic pollutants as well as other unwanted compounds which make its usefulness in direct food production (including vegetables and mushrooms) questionable [36][37][38][39]. In line with these opportunities and challenges, the lack of scientific information on the valorisation of such digestate is prominent.…”
