“…They observed that the use of microwave disintegration caused the cell walls to appear somewhat damaged and the surface roughness to increase. Kovačić et al [31] observed that the use of electroporation to pretreat the lignocellulosic substrate led to changes in the cell structure in the form of pore formation and damage to the cell membrane. SEM imaging of the control sample and the samples following disintegration was performed, for which the best technological effect was achieved in methane production.…”

“…The experiments showed that the largest increase in biogas production was achieved under the following process conditions: 15 kV/120 Hz/ 60 min-26.95%. Kovačić et al [31] examined the impact of PEF on biogas and methane productivity from maize stalks and soy straw. The use of PEF for the disintegration of maize stalks resulted in an 18% increase in biogas production and a 16% increase in methane production.…”

Lignocellulosic biomass is included in the group of renewable energy sources. Its calorific value is high, owing to which it can be successfully used in the production of second-generation fuels, e.g., biogas. However, its complex structure makes it necessary to apply a pretreatment in order to increase the biogas output. This study presents the usability of a pulsed electric field in grass silage pretreatment in methane fermentation and compares it with microwave-induced disintegration. The experiment shows that substrate disintegration with a pulsed electric field (PEF) results in an increase in methane output. The productivity of methane from PEF pretreatment silage increased by 20.1% compared to the untreated control. The application of microwave disintegration, with the assumption that the same energy is used for the pretreatment, resulted in a methane output increase of 6% compared to the control. The highest biogas production output in PEF-pretreated samples was 535.57 NL/kg VS, while the highest biogas output from substrates pretreated with microwaves was 487.18 NL/kg VS.

“…They showed that the structure of the lignocellulosic substrate was disturbed by pre-treatment. They observed that electroporation led to damage to the cell membrane and the formation of pores [28]. Liu et al performed an analysis using SEM of the effect of PEF on tea leaf.…”

“…The highest value of the methane production rate (r) was observed in the disintegrated sample for 6 min, and it was 117.06 NmL/g VS d. The highest values of the reaction rate constant were observed in the disintegrated tests for 6 and 8 min (Table 2). Research on the effect of the pre-treatment of a lignocellulosic substrate with PEF was conducted by Kovačić et al [28]. In their study, they used maize and soybean straw as lignocellulosic material.…”

“…Lignocellulosic biomass consists mainly of 30-50% cellulose, 15-35% hemicellulose and 10-20% lignin, which form a heterogeneous complex characterized by a high degree of resistance to enzymatic hydrolysis [23][24][25][26][27][28]. The structure of lignocellulosic biomass means that it is underutilized and has a low conversion rate to biogas.…”

Due to the high availability of lignocellulosic biomass, which can be obtained from terrestrial plants, agricultural waste biomass, and the agro-food, paper or wood industries, its use for energy production by methane fermentation is economically and environmentally justified. However, due to their complex structures, lignocellulosic substrates have a low conversion factor to biogas. Therefore, scientists are still working on the development of new methods of the pre-treatment of lignocellulosic materials that will increase the biogas productivity from lignocellulosic biomass. The presented research focuses on the use of a pulsed electric field (PEF) to disintegrate rapeseed straw prior to the methane fermentation process. Scanning electron microscopy observation showed that, in the disintegrated sample, the extent of damage to the plant tissue was more severe than in the control sample. In the sample disintegrated for 7 min, the chemical oxygen demand increased from 4146 ± 75 mg/L to 4920 ± 60 mg/L. The best result was achieved with a 5-min PEF pre-treatment. The methane production reached 290.8 ± 12.1 NmL CH4/g VS, and the biogas production was 478.0 ± 27.5 NmL/g VS; it was 14% and 15% higher, respectively, compared to the control sample.
