UK and Australian researchers discover how plants produce cellulose

UK and Australian researchers discover how plants produce cellulose

June 9, 2016 |

In the UK, scientists led by the University of Cambridge and the University of Melbourne have identified new steps in the way plants produce cellulose, the component of plant cell walls that provides strength, and forms insoluble fiber in the human diet. The findings could lead to improved production of cellulose and guide plant breeding […]

Patent awarded for cellulose-digesting bacteria that make ethanol 

Patent awarded for cellulose-digesting bacteria that make ethanol 

November 29, 2015 |

In Maryland, The US Patent and Trademark Office issued patent number 9,193,979 for ethanol-tolerant microorganisms that convert cellulosic biomass to ethanol.  The patent describes using the microorganisms to produce ethanol from crop or waste biomass like food waste, crop residues (e.g. corn stalks), algae, or leaves.  In contrast to most current biochemical methods to produce […]

US poised for biobased chemicals breakout, says National Research Council

US poised for biobased chemicals breakout, says National Research Council

April 5, 2015 |

Though challenges remain, particularly in affordable feedstock, the US National Research Council says “Despite impressive recent and projected growth, the manufacturing of chemicals using biological synthesis and engineering could expand even faster.” The Digest looks at the Report. In Washington, the National Research Council arm of the National Academies has released its report, “Industrialization of […]

Swiss researchers make breakthrough in cellulose pre-treatment

Swiss researchers make breakthrough in cellulose pre-treatment

May 7, 2014 |

In Switzerland, researchers at the Transport Processes and Reactions Laboratory, ETH Zurich, have found and patented a method to pretreat the plant parts in order to break up wood structures. Pretreatment increased the efficacy of the enzymes and the sugar yield increased twofold compared to steam pretreatment with no naphthol admixture.

Chip Energy breaks ground on pellet plant, to be completed this year

Chip Energy breaks ground on pellet plant, to be completed this year

July 22, 2013 |

In Illinois, Chip Energy has broken ground on a biomass recycling and pelletizing plant. The plant will produce up to 100 tons per day of condensed biomass, and is scheduled to be completed by the third quarter of this year. “I’m expecting my large clients to be utility companies that want a predictable emission briquette […]

Researchers find new method to convert cellulose for better biofuel production

Researchers find new method to convert cellulose for better biofuel production

July 2, 2013 |

In New Mexico, researchers at the Los Alamos National Laboratory (LANL) and the Great Lakes Bioenergy Research Center have determined that cellulose III has a less sticky surface, which means that a smaller quantity of enzymes get stuck to it non-productively. The GLBRC team had found that using one method of pretreatment to convert cellulose […]

Leafcutter ant enzyme beneficial to cellulosic producers

Leafcutter ant enzyme beneficial to cellulosic producers

June 20, 2013 |

In Wisconsin, researchers at the University of Wisconsin-Madison are researching an enzyme produced by leafcutter ants. The team has been able to isolate and identify the enzyme used by these critters to break down leaves and plant matter. The research, which could have tremendous implications for cellulosic producers, has encouraged several private companies to approach […]

Horse enzymes may hold key for cellulosic biofuels

Horse enzymes may hold key for cellulosic biofuels

April 15, 2013 |

In Louisiana, enzymes from fungi from the feces and intestinal tracts of horses have been discovered to break down lignin and produce cellulose effectively, and could hold the key to cutting down costs on cellulosic processes. The University of California Santa Barbara team of researchers is trying to identify the most active enzyme and working […]

UnNintendoed Consequences: Biofuels and the feedstock challenge

UnNintendoed Consequences: Biofuels and the feedstock challenge

December 12, 2012 |

It’s been years of struggle to get cellulosic feedstock supply chains downfield. Now, companies like Woodland Biofuels, Sweetwater Energy, Ceres, Delta BioRenewables and Commonwealth Agro-Energy are moving the chains. For grownups of a certain age, memories of December past take us back to childhoods before Madden Football and XBox, when Electric Football sets were found […]

ISU team deconstructs the crystalline structure of cellulose

ISU team deconstructs the crystalline structure of cellulose

March 5, 2012 |

In Iowa, Iowa State researchers are studying methods for breaking down the crystalline structure of cellulose in plants to ease the process of breaking down cellulose into sugar. Their research, which was funded by the DOE and the National Science Foundation, has recently been published in the Proceedings of the National Academy of Sciences.
