Enhancement of Biogas Production from Sewage Sludge with the Addition of Geobacillus sp. Strain AT1 Culture

Disintegration of Wastewater Activated Sludge (WAS) for Improved Biogas Production

“…Enzymatic lysis by the enzyme catalysing the reaction leads to the breaking down of bonds and compounds constituting the cell wall of the microorganisms. The enzymes can help decompose the organic matter, i.e., turn it into smaller molecules [27,38,39,[49][50][51][52][53][54][55][56][57][58][59][60][61][62]. Recently, Prajapati et al [63] successfully used a bio-electrochemical process to enhance the methane production from sewage sludge by augmenting it with food waste.…”

Alkali pretreatment enhances biogas production in the anaerobic digestion of pulp and paper sludge

“…These pretreatment methods that achieve a significant result in a lysis or disintegration of sludge cell have the potential to enhance the biogas production. Several methods have been studied in literatures with respect, including thermal [8][9][10], chemical [11][12][13], ultrasonic [14], mechanical [15] and biological [16][17][18][19][20]. While thermal pretreatment of sludge results in an increase in biodegradability, the thermal process consumes a substantial amount of energy in comparison to chemical consumption.…”

Stimulation of long-term ammonium nitrogen deposition on methanogenesis by Methanocellaceae in a coastal wetland

“…4B). Previous study showed that degradation of macromolecular hydrocarbons by Geobacillus may even lead to an increase in methane production due to a direct interaction with methanogens (Miah et al, 2004). Some methanogenic archaea can get substrates or electrons from other symbiotic bacteria, such as Clostridium (Ban et al, 2016;Jain and Zeikus, 1989).…”
