Crude glycerol by transesterification process from used cooking oils: Characterization and potentialities on hydrogen bioproduction
(2016-09-07)
This study evaluated the potential bioconversion of crude glycerol from biodiesel production, applying used cooking oil for biohydrogen production by fermentative bacteria consortia. The pretreatment of crude glycerol was ...
Performance evaluation and phylogenetic characterization of anaerobic fluidized bed reactors using ground tire and pet as support materials for biohydrogen production
(2011)
This study evaluated two different support materials (ground tire and polyethylene terephthalate [PET]) for biohydrogen production in an anaerobic fluidized bed reactor (AFBR) treating synthetic wastewater containing glucose ...
Hydrogen bioproduction with anaerobic bacteria consortium from brewery wastewater
(2018-01-01)
Biohydrogen production is a cheap and clean way to obtain hydrogen gas. In subtropical countries such as Brazil the average temperatures of 27 °C can favor the hydrogen producing bacteria growth. A mixed culture was obtained ...
Hydrogen bioproduction with Enterobacter sp. isolated from brewery wastewater
(2017-01-05)
Hydrogen-producing bacterial strains were isolated from granular sludge from a UASB reactor that treats brewery wastewater. Most of the isolated strains were related to the Enterobacter genus through a phylogenetic analysis ...
Obtenção de consórcio de bactérias fotoheterotróficas geradoras de H2 visando sua produção em reator anaeróbio em batelada
(Universidade Estadual Paulista (UNESP), 2016)
Determination of alcohols and volatile organic acids in anaerobic bioreactors for H2 production by near infrared spectroscopy
(2017-08-10)
In recent years, near infrared (NIR) spectroscopy has been investigated as a tool for monitoring anaerobic digesters, but several adversities in its application have been reported. This study proposes the application of ...
Obtenção de consórcio de bactérias fotoheterotróficas geradoras de H2 visando sua produção em reator anaeróbio em batelada
(Universidade Estadual Paulista (Unesp), 2016-04-04)
A bioconversão de diferentes materiais orgânicos em hidrogênio é uma tecnologia sustentável. Inóculos de climas tropicais, como o Brasil, com temperaturas médias de 25°C podem favorecer o crescimento bacteriano. A geração ...
Acidic and thermal pre-treatments for anaerobic digestion inoculum to improve hydrogen and volatile fatty acid production using xylose as the substrate
(2020-01-01)
Xylose is a by-product of lignocellulosic biomass processing for production of second-generation biofuels and could be suitable for bioproduct manufacturing. This paper describes an innovative approach that enables the ...
Supported ruthenium catalysts for the aqueous-phase selective hydrogenation of furfural to furfuryl alcohol
(Elsevier Science, 2022-07-23)
One of the products that can be obtained from biomass by thermal dehydration of sugars is furfural which has great potential as a renewable chemical platform for obtaining bioproducts. Through hydrogenation of furfural, ...
