Growth of engineered Pseudomonas putida on glucose, xylose and arabinose

Growth of engineered Pseudomonas putida on glucose, xylose and arabinose

January 25, 2019 |

In Germany, researchers from Ulm University engineered Pseudomonas putida KT2440 as microbial biocatalyst for the utilization of xylose and arabinose in addition to glucose as sole carbon sources. What they found was surprising in that both recombinant strains were able to grow on xylose as well as arabinose with high cell densities and growth rates […]

Arizona State University researchers make breakthrough on breaking down xylose

Arizona State University researchers make breakthrough on breaking down xylose

July 3, 2017 |

In Arizona, researchers at Arizona State University wanted to squeeze out more energy from xylose sugars. To do so, they challenged E. coli bacteria that could thrive comfortably on glucose — and switch out the growth medium broth to grow solely on xylose. The bacteria would be forced to adapt to the new food supply […]

C5 is the new C6

C5 is the new C6

Goodbye glucose, hello xylose. The X-Factor in the advanced bioeconomy might just be a sugar that starts with an X. You’ve long noticed that water gathers in beads — on a leaf in the morning, for example, or dripping from a faucet. That’s surface tension, which is to say that the water is more attracted […]

Researchers develop better microbial conversion pathway for xylose

Researchers develop better microbial conversion pathway for xylose

December 30, 2014 |

In New York state, a researcher from Hofstra University has led a team that discovered a microbial conversion pathway using Clostridium clariflavum to better degrade xylan to xylooligomers and xylose which also appears to allow higher utilization of unused biomass. The research used switchgrass as feedstock.

Xylitol Canada completes technology demonstration of xylose production process

Xylitol Canada completes technology demonstration of xylose production process

June 18, 2013 |

In Canada, Xylitol Canada announced they have completed pilot demonstration of its cellulosic xylose process. The successful three month campaign proved out critical process and economic metrics needed to advance into commercial scale detailed engineering.  The recently completed trial builds on previously completed pilot scale work by integrating the Xylitol Canada process from end-to-end in […]

New yeast boosts xylose-to-ethanol efficiencies

New yeast boosts xylose-to-ethanol efficiencies

February 1, 2012 |

In Brazil, researchers from the University of Sao Paolo have successfully developed a new fermentation process with 63% efficiency for producing ethanol from xylose using the yeast Pichia stipitis. Pichia stipitis NRRL Y-7124 was able to grow and produce ethanol from xylose in a stirred tank bioreactor under different aeration and agitation conditions.

Ethanol from xylose: new paths from Sweden

Ethanol from xylose: new paths from Sweden

[ 0 ] March 11, 2011 |

In Sweden, Lund University research Nadia Skorupa Parachin has extracted enzymes from garden soil to convert xylose, the world’s second most common sugar, to ethanol.  If successful, ethanol production could possibly increase by 20%. Ms Skorupa Parachin explains, “In order for carbohydrates in forestry, plant and waste products to be used for ethanol production, enzymes […]
