Journal ArticleDOI
Effect of selected aldehydes on the growth and fermentation of ethanologenic Escherichia coli.
TL;DR: Of the aldehydes tested, only furfural strongly inhibited ethanol production in vitro, and a comparison with published results for other microorganisms indicates that LY01 is equivalent or more resistant than other biocatalysts to the aaldehydes examined in this study.
Journal ArticleDOI
Detoxification of dilute acid hydrolysates of lignocellulose with lime
Alfredo Martinez,María Eugenia Rodríguez,María Eugenia Rodríguez,Melissa L. Wells,Sean W. York,James F. Preston,Lonnie O. Ingram +6 more
TL;DR: Using ethanologenic Escherichia coli LY01 as the biocatalyst, the results indicate that the optimal lime addition for detoxification varies and depends on the concentration of mineral acids and organic acids in each hydrolysate.
Journal ArticleDOI
Effects of Ca(OH)(2) treatments ("overliming") on the composition and toxicity of bagasse hemicellulose hydrolysates.
Alfredo Martinez,María Eugenia Rodríguez,María Eugenia Rodríguez,Sean W. York,James F. Preston,Lonnie O. Ingram +5 more
TL;DR: Titration of acids, measurement of pH before and after treatment, and furan analyses are proposed as relatively simple methods to monitor the reproducibility of hydrolysate preparations and the effectiveness of overliming treatments.
Journal ArticleDOI
Enteric bacterial catalysts for fuel ethanol production
Lonnie O. Ingram,Henry C. Aldrich,A. C. C. Borges,T. B. Causey,Alfredo Martinez,Fernando Martinez Morales,Alif Z. Saleh,S. A. Underwood,Lorraine P. Yomano,Sean W. York,Jesus Zaldivar,Shengde Zhou +11 more
TL;DR: The general approach for the genetic engineering of new biocatalysts using the PET operon has been most successful with Enteric bacteria but was also extended to Gram positive bacteria, which have other useful traits for lignocellulose conversion.
Journal ArticleDOI
Effect of alcohol compounds found in hemicellulose hydrolysate on the growth and fermentation of ethanologenic Escherichia coli.
TL;DR: Alcohol components which are formed during hemicellulose hydrolysis are less toxic for growth than the aldehydes and organic acids either on a weight basis or a molar basis.
