Autor: Iván Paredes, Julián Quintero, Karlo Guerrero, Roberto Gallardo, Silvia Mau, Raúl Conejeros, Juan Carlos Gentina, German Aroca

Publikováno v: Electronic Journal of Biotechnology, Vol 56, Iss , Pp 12-21 (2022)

Background: In solvent-producing Clostridium species, several physiological conditions and morphological forms can be observed during batch ABE fermentation. Currently, the contribution made by each condition or form to the production of acids and so

Sticky Bacteria: Understanding the Behavior of a D-Galactose Adapted Consortium of Acidophilic Chemolithotroph Bacteria and Their Attachment on a Concentrate of Polymetallic Mineral

Autor: Paulina Aguirre, Albert Saavedra, Eduardo Moncayo, Sabrina Hedrich, Karlo Guerrero, Juan Carlos Gentina

Publikováno v: Frontiers in Microbiology, Vol 12 (2021)

Various strategies to accelerate the formation of biofilms on minerals have been studied, and one of them is the use of D-galactose as an inducer of EPS production in planktonic cells of biooxidant bacteria. With the aim to evaluate the influence on

Release of formaldehyde during the biofiltration of methanol vapors in a peat biofilter inoculated with Pichia pastoris GS115

Autor: Karlo Guerrero, Alejandra Arancibia, Manuel Caceres, German Aroca

Publikováno v: Electronic Journal of Biotechnology, Vol 40, Iss , Pp 10-16 (2019)

Background: Methanol can be effectively removed from air by biofiltration. However, formaldehyde is one of the first metabolic intermediates in the consumption of methanol in methylotrophic microorganisms, and it can be released out of the cell const

Release of formaldehyde during the biofiltration of methanol vapors in a peat biofilter inoculated with Pichia pastoris GS115

Autor: Karlo Guerrero, Alejandra Arancibia, Manuel Caceres, German Aroca

Publikováno v: Electronic Journal of Biotechnology, Vol 44, Iss , Pp 58-59 (2020)

Background: Methanol can be effectively removed from air by biofiltration (Shareefdeen et al., 1993; Babbitt et al., 2009 [1,2]). However, formaldehyde is one of the first metabolic intermediates in the consumption of methanol in methylotrophic micro

Continuous biohydrogen production by a degenerated strain of Clostridium acetobutylicum ATCC 824

Autor: Karlo Guerrero, Iván Paredes, Raúl Conejeros, Roberto Gallardo, Julián Quintero, Silvia Mau, Juan Carlos Gentina, Germán Aroca

Publikováno v: International Journal of Hydrogen Energy. 46:5100-5111

Degenerated strains of Clostridium acetobutylicum lack the ability to produce solvents and to sporulate, allowing the continuous production of hydrogen and organic acids. A degenerated strain of Clostridium acetobutylicum was obtained through success

Kinetic model of Clostridium beijerinckii's Acetone-Butanol-Ethanol fermentation considering metabolically diverse cell types

Autor: Germán Aroca, Iván Paredes, Juan Carlos Gentina, Silvia Mau, Raúl Conejeros, Julián A. Quintero, Karlo Guerrero, Marcelo Rivas-Astroza

Publikováno v: Journal of biotechnology. 342

Clostridium beijerinckii population branches into metabolically diverse cell types in batch cultures. Here, we present a new kinetic model of C. beijerinckii’s Acetone-Butanol-Ethanol fermentation that considers three cell types: producers of acids

Making sticky cells: effect of galactose and ferrous iron on the attachment of Leptospirillum ferrooxidans to mineral surfaces

Autor: Karlo Guerrero, Aminael Sánchez-Rodríguez, Paulina Aguirre, Axel Schippers, Juan Carlos Gentina

Publikováno v: Research in Microbiology. 169:569-575

The purpose of this study was to compare the efficacy of galactose and high initial ferrous iron concentrations as inducers for extracellular polymeric substances (EPS) production in planktonic cells of Leptospirillum ferrooxidans and to study cell a
