“Different pretreatments of beach-cast seaweed for biogas production”

Prediction of methane yield and pretreatment efficiency of lignocellulosic biomass based on composition

“…Sugar detection and quantification (glucose, xylose, arabinose) was carried out by means of high performance liquid chromatography (HPLC, Shimadzu, USA) equipped with a refractive index detector (Lymperatou et al, 2017). The CH 4 content in biogas samples was determined by means of a gas chromatograph (GC82-22, Mikrolab Aarhus, Denmark) equipped with a thermal conductivity detector (Lymperatou et al, 2022).…”

Effects of different treatments of manure on mitigating methane emissions during storage and preserving the methane potential for anaerobic digestion

“…According to the results of BMP tests, pasteurization enhanced the CH 4 potential after storage. In order to assess at which extent pasteurization affected the hydrolysis rate of the solid matrix, as it has been reported for other treatments as well (Lymperatou et al, 2020(Lymperatou et al, , 2021(Lymperatou et al, , 2022, BMP experiments of the solid fraction of the control sample and of the solid fraction of one of the pasteurized samples (70 • C, 90 min) were carried out. The experiment was performed using a pasteurized sample and a control sample that had not been stored, in order to isolate the effect of the treatment from any potential effect from the storage.…”

Sustainable enhancement of biogas and methane yield of macroalgae biomass using different pretreatment techniques: A mini-review

“…38 In another study, beach-cast seaweed was digested in a lab-scale batch reactor at mesophilic conditions (37 ± 2 °C), and a methane yield of 106 ± 1 mL/g VS added was recorded after 35 days of retention time. 39 Red macroalgae Palmaria palmata was investigated for biogas production potential in a batch digester at mesophilic conditions, and it was reported that 308 ± 9 mL g −1 VS was obtained. 40 Different species of macroalgae were studied for their biogas production potential by Tedesco et al, and these include Pelvetia caniculata, Fucus serratus, Gracilaria gracilis, Ffucus vesiculosus linnaeus, and Laminaria digitat.…”
