“…The insights from the literature offer various ranges of the C:N ratio to achieve the adequate course of the methane fermentation process. Abbasi et al [32] give that this ratio should be 20-30 :1, whereas the work [24,33] describes an experiment conducted in the conditions when the C:N ratio was 15-30:1. However, these authors found that microorganisms should have a ration of C:N 20-30:1 to ensure their optimum growth [24,31].…”

Another range of the C:N that was found to be optimum for the composition of the input for biogas production is equal to 10-25:1.…”

Abstract. Recently, the idea of biogas production has become a popular topic in Poland. Biogas is a valuable source of renewable energy with a potential application in electricity and heat production. Numerous types of technological solutions of biogas production are closely linked to the availability of substrates in the area, as well as their quantity and their properties. The paper presents the assessment of application in biogas production selected wastes such as communal and household sewage sludge and waste from a paper production in Opole region (Poland). The annual productions of methane, biogas and electricity were estimated. Chosen physico-chemical properties important in fermentation process were taken into consideration in the assessment. The highest value of potential energy was obtained using waste from the paper industry but the most appropriate parameters for this process has sewage sludge from the municipal sewage treatment plant. The use of sewage sludge from domestic and municipal sewage and waste from the paper industry creates the opportunity to reduce the amount of waste materials.

Section: An Overview Of Antibiotic Inhibition Of Admentioning

confidence: 99%

“…The stability of an AD system depends highly upon the synergetic interactions and the delicate balance among various groups of microorganisms, namely fermentative bacteria, acidogens, acetogens, and methanogens. [43] Disruption of the metabolic dynamics by inhibitory substances could result in process failure. By studying the impacts of different antibiotics on the changes in microbial community and functions at different stages of an AD process, Mustapha et al [44] confirmed that antibiotics have little effect on the hydrolysis, acidogenesis, and acetogenesis stages, whereas lower methanogenesis activity was observed in the presence of chloramphenicol.…”

Despite the efficacy of anaerobic digestion (AD) in stabilizing animal wastes as well as alleviating global warming associated with natural decomposition of animal manure, the process is susceptible to antibiotics that commonly exist in animal manure. Although antibiotics have served veterinary purposes in large quantities for decades, knowledge concerning their impacts on methane production during AD of animal manure is still in its infancy. Antibiotics used in animal practice are recognized as one of the major contributors to the development of resistant pathogens. Their fate and long‐term environmental impacts following land application or disposal of the animal manure into the aquatic environment, with resistance development and associated risks on human health as the primary focus, are well reviewed in many previous publications. To date, to the best of our knowledge, few efforts are made on reviewing the impacts of antibiotics on AD of animal manure and the mitigation strategies. In this review, detailed summaries of earlier and recent works conducted on the inhibition of antibiotics on AD of animal manure are presented, with special interest directed toward available and new controlling strategies in terms of technical and regulatory aspects. Finally, in view of process balance and successive operation, further research should be carried out to gain insight into dynamic interactions of antibiotics and other commonly seen coexistent inhibitors/intermediates in the AD systems.

“…In third step (acetogenesis), the products of acidogenesis are converted to acetic acid, hydrogen and carbon dioxide by acetogenic bacteria. Methanogenesis is the final stage whereby methanogenes bacteria converts hydrogen, acetic acid and carbon dioxide to methane and carbon dioxide [3]. The factors that affects biogas production is: pH, temperature, the nature of the substrate, C/N ratio and the exposure of oxygen to the process [4].…”
