“…An aliquot of 5 g of a composting sample was added to 50 ml of sterile water and mixed completely to generate a bacterial solution. The DNA of the solution was extracted using a TIANamp Bacteria DNA Kit (Tiangen Biotech Beijing Co., Ltd., China) followed by amplification on a real‐time PCR system (ABI 7500; Applied Biosystems, Foster City, CA, USA) with a forward primer (519F, 5‐CAGCMGCCGCGGTAATWC‐3), and reverse primer (907R, 5‐CCGTCAATTCMTTTRAGTTT‐3) (Zhang et al ., ). The qPCR products were electrophoresed on a 1% agarose gel containing ethidium bromide and visualized using a gel image processing system (Tanon‐1600; Tanon Science & Technology Co., Ltd., Shanghai, China).…”

Summary Aerobic composting is a bacteria‐driven process to degrade and recycle wastes. This study quantified the kinetics of bacterial growth and decay during pig manure–wheat straw composting, which may provide insights into microbial reaction mechanisms and composting operations. First, a propidium monoazide–quantitative polymerase chain reaction ( PMA – qPCR ) method was developed to quantify the viable bacteria concentration of composting samples. The optimal PMA concentration and light exposure time were 100 μM and 8 min respectively. Subsequently, the concentrations of total and decayed bacteria were quantified. Viable and decayed bacteria coexisted during the entire composting period (experiments A and B), and the proportion of viable bacteria finally fell to only 35.1%. At the beginning, bacteria grew logarithmically and decayed rapidly. Later, the bacterial growth in experiment A remained stable, while that of experiment B was stable at first and then decomposed. The duration of the stable stage was positively related to the soluble sugar content of composting materials. The logarithmic growth and rapid decay of bacteria followed Monod equations with a specific growth (0.0317 ± 0.0033 h −1 ) and decay rate (0.0019 ± 0.0000 h −1 ). The findings better identified the bacterial growth stages and might enable better prediction of composting temperatures and the degree of maturation.

“…FQs were found to be resistant to hydrolysis and biodegradation [31,68]. However, they are susceptible to phototransformation; hence photochemical transformation is supposed to be a great remediation strategy for surface water FQs contamination [193,208,227,229] showed complete degradation of ciprofloxacin in the presence of bismuth oxybromide (BiObR), while minimal degradation was observed without BiOBr or irradiation. This degradation occurred with an oxidation reaction.…”

Perspectives on the antibiotic contamination, resistance, metabolomics, and systemic remediation

Antibiotics have been regarded as the emerging contaminants because of their massive use in humans and veterinary medicines and their persistence in the environment. The global concern of antibiotic contamination to different environmental matrices and the emergence of antibiotic resistance has posed a severe impact on the environment. Different mass-spectrometry-based techniques confirm their presence in the environment. Antibiotics are released into the environment through the wastewater steams and runoff from land application of manure. The microorganisms get exposed to the antibiotics resulting in the development of antimicrobial resistance. Consistent release of the antibiotics, even in trace amount into the soil and water ecosystem, is the major concern because the antibiotics can lead to multi-resistance in bacteria which can cause hazardous effects on agriculture, aquaculture, human, and livestock. A better understanding of the correlation between the antibiotic use and occurrence of antibiotic resistance can help in the development of policies to promote the judicious use of antibiotics. The present review puts a light on the remediation, transportation, uptake, and antibiotic resistance in the environment along with a novel approach of creating a database for systemic remediation, and metabolomics for the cleaner and safer environment.

“…Antibiotics and antiparasitics present in manure (especially manure from animals that are given veterinary care) could potentially pose a problem for the disposal of this manure . Several studies have demonstrated the degradation of antibiotics during composting processes (Dolliver et al, 2008;Ho et al, 2013;Zhang et al, 2015) although the relative roles of (actino-)bacteria and fungi in antibiotic degradation are still poorly known. Moreover, differences between fungal species in their ability to degrade antibiotics and antiparasitics of various classes have hardly been studied.…”

In nature manure is recycled by unique fungi (coprophilic fungi), which are capable of growth on substrates with high nitrogen contents. They bind a lot of the nutrients and in a delayed release they are making these nutrients available for plants, animals and insects, thereby closing nutrient cycles. This may provide opportunities for processing of manure.Within project KB-40-005-008; Closing the loop: improving circularity with manure-loving mushrooms), part of the Investment theme Connected circularity, we have been provided with the opportunity to work on a this topic.A literature study was performed on the options that coprophilic fungi offer. It focused on the taxonomic and ecological knowledge of coprophilous mushrooms present in the Netherlands and on the threats of fungal diversity on dung. Next to this the literature study focusses on the options that coprophilous fungi offer as a source of secondary metabolites or enzymes. Furthermore it briefly focusses on an overview of genomes available of coprophilous fungi. The literature study is finalized with a brief outlook towards possibilities of using coprophilous mushrooms in a circular agriculture system.In the second part of the project we able to build a collection of coprophilic basidiomycete strains comprising of 38 strains distributed over at least 23 species. Limited tests of their ability to grow on a small range of types of manure demonstrated growth of 23 strains on chicken manure (ranging from limited growth to abundant growth). A total of 19 strains showed growth on cow manure (again ranging from limited growth to abundant growth). Pig manure was least favorite in our experiments, with only 4 strains showing growth with different abundances.We believe that this project will provide a starting point for a study of applicability of coprophilic fungi in circular agriculture..
