“…The methane yields were below 50 L/kg-VS. Digesters with the third-harvest biomass had normal pH conditions and produced 171.80 ± 4.82 L of methane per kg-VS at a TS of 4%, as shown in Figure 2A and Table S1, which is still lower than reported methane yields from the other lignocellulosic biomass. For example, previous studies have reported methane yields of 187, 182-285, and 179-274 L/kg-VS from cereal rye [55], corn stover [56,57], and wheat straw [58,59], respectively. Measured methane yields at a F/I ratio of 2, from biomass cut to 2.54 cm lengths (A) or to 1.27 cm lengths (B).…”

Pennycress (Thlaspi arvense L.) is an annual cover crop known for its exceptional cold tolerance and high oil and protein yields. Pennycress can be integrated into a corn–soybean rotation in the U.S. However, the utilization of pennycress biomass remains largely unexplored, including assessing compositional changes through its growth and organic matter digestibility. This study harvested pennycress at three growth stages, characterized the biomass for anaerobic digestion (AD), and tested the effects of concurrent alkali pretreatment and ensiling on the biomass methane yield. Results showed that the biomass harvested when the plants were undergoing senescence (“third-harvest”) had higher contents of acid detergent fiber, neutral detergent fiber, and lignin, while the biomass harvested when 80–90% of the pods were fully-sized (“second-harvest”) had the highest protein content. The AD experiments showed that the first-harvest biomass (90% of flowers opened) failed to produce biogas due to a drop in the pH and alkalinity, the second-harvest biomass was inhibited for methane production (45.74 ± 0.20 L/kg-VS), and the third-harvest biomass had a methane yield of 171.80 ± 4.82 L/kg-VS. After the alkali pretreatment and ensiling, a methane yield of 270.4 ± 3.10 L/kg-VS was obtained from the second-harvest biomass, representing a significant 4.5-fold increase (adjusted for the organic matter loss) relative to the untreated second-harvest biomass.

“…Various biomass sources, including agricultural and forestry waste as well as aquatic sources, have been proposed for biofuel production, such as biodiesel, bioethanol, biohydrogen, bio-oil, and biogas. However, the environmental impact and limited availability of these biomass sources have raised concerns about sustainability and forest destruction [54,89,[98][99][100][101][102][103]. This has led to a focus on algal biomass as a promising alternative for biofuel production.…”

“…To produce biofuels like biodiesel, bioethanol, biohydrogen, bio-oil, and biogas, a variety of biomass sources have been suggested. These sources include aquatic sources as well as agricultural and forestry waste [54,[98][99][100][101]126]. However, the negative effects on the environment and the scarcity of these biomass sources have prompted questions about sustainability and the loss of forests [28,102,103].…”

Bioenergy productions from microalgae have received wide attention recently and have a high potential to replace fossil fuels. Moreover, due to the high photosynthetic efficiency, microalgae mass cultivation and scale-up are believed to efficiently reduce the impact of greenhouse gas emissions. This review article explores the potential of microalgae as a reliable and sustainable source of bioenergy feedstock. The current review article contains an in-depth discussion of the various methods of producing energy using microalgae, viz. algal fuel cell (AFC), microbial fuel cell (MFC), bioethanol and biodiesel, and various other applications. This article discussed the different aspects of AFC and MFC, such as fuel cell configurations, reaction mechanisms at electrodes, reactor design factors affecting the efficiencies, and strategies to enhance the efficiencies. Moreover, microalgae cultivation, value-added compounds (pigments, polysaccharides, unsaturated fatty acids), liquid fuel production, limitations, the global scenario of microalgae biomass-based energy, and significant advancements in this field. In a nutshell, this review serves as a valuable resource for identifying, developing, and harnessing the potential of microalgae as a promising biofuel source.

“…Recent reports of the Intergovernmental Panel on Climate Change (IPCC) have reported the projected production of bioenergy to 100 EJ by 2050, which will account for almost 20% of the total energy needs [2][3][4][5]. Correspondingly, biogas is one of the sources of bioenergy produced through the anaerobic digestion (AD) of an organic matter in a cost-effective manner using a group of microorganisms [6][7][8]. It has gained attention in the past few decades to meet the demands for heat, electricity, and transportation fuel whilst reducing the environmental impact.…”

Thermophilic Anaerobic Digestion: An Advancement towards Enhanced Biogas Production from Lignocellulosic Biomass

et al. 2023

View full text Add to dashboard Cite

Thermophilic anaerobic digestion (TAD) technology has been adopted worldwide mainly due to it being a pathogen-free process in addition to the enhanced biogas yield and short hydraulic retention time (HRT). Taking the high metabolic rate of the thermophilic microbial community with highly efficient enzymatic systems into consideration, thermophiles are being widely explored as efficient inocula for lignocellulosic biomass (LCB) degradation and improved biomethane production. The advantages of TAD over mesophilic anaerobic digestion (MAD), including improved kinetics, efficient degradation of organic matter, and economic and environmental sustainability, make it one of the best strategies to be operated at moderately high temperatures. This review sheds light on the relevant role of thermophilic microorganisms as inocula in the anaerobic digestion of organic matter and factors affecting the overall process stability at high temperatures. Further, the discussion explains the strategies for enhancing the efficiency of thermophilic anaerobic digestion.
