Ionic liquid-mediated technology to produce cellulose nanocrystals directly from wood.
Carbohydr. Polym. 134 , 609-16, (2015) We report for the first time the direct extraction of cellulose nanocrystals (CNCs) from wood by means of a 1-ethyl-3-methylimidazolium acetate ([EMIM][OAc]) treatment. A native cellulosic product could be recovered in 44% yield with respect to wood cellulose... |

Imaging with the fluorogenic dye Basic Fuchsin reveals subcellular patterning and ecotype variation of lignification in Brachypodium distachyon.
J. Exp. Bot. 66 , 4295-304, (2015) Lignin is a complex polyphenolic heteropolymer that is abundant in the secondary cell walls of plants and functions in growth and defence. It is also a major barrier to the deconstruction of plant biomass for bioenergy production, but the spatiotemporal detai... |

Ab initio study of the barriers to methyl torsion and torsional frequencies of acetyl molecules.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 61(7) , 1471-7, (2005) A wide range of ab initio and hybrid density functional methods and basis sets have been employed to calculate the barriers to methyl internal rotation in a range of molecules with the acetyl moiety. Comparison is made of the computed torsional frequency with... |

Rapid, microscale, acetyl bromide-based method for high-throughput determination of lignin content in Arabidopsis thaliana.
J. Agric. Food Chem. 56(16) , 6825-34, (2008) The acetyl bromide method has been modified to enable the rapid microscale determination of lignin content in Arabidopsis with the goal of determining the genes that control lignin in plants. Modifications include reduction in sample size, use of a microball ... |

Laser microdissection and genetic manipulation technologies to probe lignin heterogeneity and configuration in plant cell walls.
Methods Mol. Biol. 908 , 229-50, (2012) Single and multiple T-DNA knockouts of genes encoding arogenate dehydratases (ADTs) in Arabidopsis were obtained in homozygous form. These were analyzed for potential differences in lignin contents and compositions, as well as for distinct phenotypes over gro... |

Formal synthesis of (±)-methyl rocaglate using an unprecedented acetyl bromide mediated Nazarov reaction.
J. Am. Chem. Soc. 134(14) , 6140-2, (2012) To date the prototype Nazarov cyclization of a cross-conjugated pentadienone to the core structure of the rocaglate natural products has not been successful (9 into 12). It has been found that this conversion can be achieved by the use of acetylbromide in exc... |

Accurate and reproducible determination of lignin molar mass by acetobromination.
J. Agric. Food Chem. 60(36) , 8968-73, (2012) The accurate and reproducible determination of lignin molar mass by using size exclusion chromatography (SEC) is challenging. The lignin association effects, known to dominate underivatized lignins, have been thoroughly addressed by reaction with acetyl bromi... |

Comparison of the acetyl bromide spectrophotometric method with other analytical lignin methods for determining lignin concentration in forage samples.
J. Agric. Food Chem. 52(12) , 3713-20, (2004) Present analytical methods to quantify lignin in herbaceous plants are not totally satisfactory. A spectrophotometric method, acetyl bromide soluble lignin (ABSL), has been employed to determine lignin concentration in a range of plant materials. In this work... |

Extraction and isolation of lignin for utilization as a standard to determine lignin concentration using the acetyl bromide spectrophotometric method.
J. Agric. Food Chem. 49(7) , 3133-9, (2001) Lignin extracted with acidic dioxane was investigated as a possible standard for quantitatively determining lignin content in plant samples using the spectrophotometric method employing acetyl bromide. Acidic dioxane lignins were analyzed for carbohydrate, to... |
