Impact of protein-, lipid- and cellulose-containing complex substrates on biogas production and microbial communities in batch experiments

Effects of organic composition on mesophilic anaerobic digestion of food waste

“…Anaerobic digestion (AD) has been widely used for treating food waste (FW), and the digestion performance (e.g. biogas production, organic reduction, inhibition characteristics and process stability) is highly dependent on the feedstock's characteristics (Wagner et al, 2013). FW consists of three principal organic components: carbohydrates, proteins and lipids, and the volatile solid to total solid (VS/TS) ratios typically range from 80 to 97% (Jin et al, 2015;Zhang et al, 2014;Zhang et al, 2007).…”

Biological pre-treatment: Enhancing biogas production using the highly cellulolytic fungus Trichoderma viride

“…Some basic parameters and running conditions can be found in Wagner et al (2014). The DFS used as inoculum in the present investigations was prepared anaerobically as described previously (Wagner et al, 2013a). The anaerobic incubation period extended over 14 days in total at 52°C, with samples withdrawn on day 0, 1, 2, 4, 7, 10, 12 and 14 from the bottles headspace and analyzed on CH 4 , CO 2 and H 2 by gas chromatography on a Shimadzu GC 2010 as described in Wagner et al (2011).…”

Biochemical and chemical technology for a virtuous bio-waste cycle to produce biogas without ammonia and speciality bio-based chemicals with reduced entrepreneurial risk

“…This process is run to recover the heat value of the bio‐waste organic matter as biomethane. Indeed, the process converts the polysaccharide, fat and protein fraction of the bio‐waste organic matter to biogas, whereas the lignin fraction remains in the digestate . Unfortunately, the process requires a secondary treatment of the digestate.…”
