(MDPI, 2022-03-14)[Abstract] The impetus to predicting future biomass consumption focuses on sustainable energy, which concerns the non-renewable nature of fossil fuels and the environmental challenges associated with fossil fuel burning. ... -
Advances in the development of electrode materials for improving the reactor kinetics in microbial fuel cells
Agrahari, Roma; Bayar, Büşra; Nalakath Abubackar, Haris; Giri, BS; Rene, Eldon R.; Rani, Radha (Elsevier, 2021-12-07)[Abstract] Microbial fuel cells (MFCs) are an emerging technology for converting organic waste into electricity, thus providing potential solution to energy crises along with eco-friendly wastewater treatment. The electrode ... -
Bioconversion of carbon monoxide-related volatile compounds into ethanol in bioreactors
Nalakath Abubackar, Haris (2015)[Resumen]Los problemas ambientales asociados al uso de combustibles fósiles, así como su esperada escasez en un futuro próximo, exigen la búsqueda de nuevos combustibles alternativos, como el bioetanol obtenido a partir ... -
Biological conversion of carbon monoxide to ethanol: Effect of pH, gas pressure, reducing agent and yeast extract
Nalakath Abubackar, Haris; Veiga, María Carmen; Kennes, Christian (Elsevier, 2012-06)A two-level full factorial design was carried out in order to investigate the effect of four factors on the bioconversion of carbon monoxide to ethanol and acetic acid by Clostridium autoethanogenum: initial pH (4.75–5.75), ... -
Biological conversion of carbon monoxide: rich syngas or waste gases to bioethanol
Nalakath Abubackar, Haris; Veiga, María Carmen; Kennes, Christian (Wiley-Blackwell, 2011)Bioconversion of syngas/waste gas components to produce ethanol appears to be a promising alternative compared to the existing chemical techniques. Recently, several laboratory-scale studies have demonstrated the use of ... -
Bioprocesses for resource recovery from waste gases: Current trends and industrial applications
Khanongnuch, Ramita; Nalakath Abubackar, Haris; Keskin Gundogdu, Tugba; Güngörmüşler, Mine; Duman, Gozde; Agrawal, Ayushi; Behera, Shishir Kumar; Li, Lu; Bayar, Büşra; Rene, Eldon R. (Elsevier, 2021-12-27)[Abstract] Air pollution is a topic of important global concern because it has contributed significantly to an increase in the earth's global warming potential and contributed to severe health and environmental impacts. ... -
Carbon monoxide fermentation to ethanol by Clostridium autoethanogenum in a bioreactor with no accumulation of acetic acid
Nalakath Abubackar, Haris; Veiga, María Carmen; Kennes, Christian (Elsevier, 2015-06)[Abstract] Fermentation of CO or syngas offers an attractive route to produce bioethanol. However, during the bioconversion, one of the challenges to overcome is to reduce the production of acetic acid in order to minimize ... -
Design of Low-Cost Ethanol Production Medium From Syngas: An Optimization of Trace Metals for Clostridium Ljungdahlii
Sertkaya, Simge; Azbar, Nuri; Nalakath Abubackar, Haris; Keskin Gundogdu, Tugba (MDPI, 2021-10-25)[Abstract] Syngas fermentation via the Wood-Ljungdahl (WL) pathway is a promising approach for converting gaseous pollutants (CO and CO2) into high-value commodities. Because the WL involves several enzymes with trace metal ... -
Effect of pH, Yeast Extract and Inorganic Carbon on Chain Elongation for Hexanoic Acid Production
San-Valero, Pau; Nalakath Abubackar, Haris; Veiga, María Carmen; Kennes, Christian (Elsevier, 2019-12-29)[Abstract] Several anaerobic bioconversion technologies produce short chain volatile fatty acids and sometimes ethanol, which can together be elongated to hexanoic acid (C6 acid) by Clostridium kluyveri in a secondary ... -
