| genetic engineering of enterobacter asburiae strain jdr-1 for efficient production of ethanol from hemicellulose hydrolysates. | dilute acid pretreatment is an established method for hydrolyzing the methylglucuronoxylans of hemicellulose to release fermentable xylose. in addition to xylose, this process releases the aldouronate methylglucuronoxylose, which cannot be metabolized by current ethanologenic biocatalysts. enterobacter asburiae jdr-1, isolated from colonized wood, was found to efficiently ferment both methylglucuronoxylose and xylose in acid hydrolysates of sweet gum xylan, producing predominantly ethanol and ac ... | 2009 | 19617386 |
| genetic engineering of enterobacter asburiae strain jdr-1 for efficient d(--) lactic acid production from hemicellulose hydrolysate. | in the dilute acid pretreatment of lignocellulose, xylose substituted with alpha-1,2-methylglucuronate is released as methylglucuronoxylose (megax), which cannot be fermented by biocatalysts currently used to produce biofuels and chemicals. enterobacter asburiae jdr-1, isolated from colonized wood, efficiently fermented both megax and xylose in acid hydrolysates of sweetgum xylan. deletion of pflb and als genes in this bacterium modified the native mixed acid fermentation pathways to one for hom ... | 2009 | 19504045 |

| hydrogen production from formic acid in ph-stat fed-batch operation for direct supply to fuel cell. | enterobacter asburiae snu-1 harvested after cultivation was used as a whole cell biocatalyst, for the production of hydrogen. formic acid was efficiently converted to hydrogen using the harvested cells with an initial hydrogen production rate and total hydrogen production of 491 ml/l/h and 6668 ml/l, respectively, when 1 g/l of whole cell enzyme was used. moreover, new ph-stat fed-batch operation was conducted, and total hydrogen production was 1.4 times higher than that of batch operation. for ... | 2010 | 19364642 |
| complete fermentation of xylose and methylglucuronoxylose derived from methylglucuronoxylan by enterobacter asburiae strain jdr-1. | acid pretreatment is commonly used to release pentoses from the hemicellulose fraction of cellulosic biomass for bioconversion. the predominant pentose in the hemicellulose fraction of hardwoods and crop residues is xylose in the polysaccharide methylglucuronoxylan, in which as many as one in six of the beta-1,4-linked xylopyranose residues is substituted with alpha-1,2-linked 4-o-methylglucuronopyranose. resistance of the alpha-1,2-methylglucuronosyl linkages to acid hydrolysis results in relea ... | 2009 | 19011070 |
