as a biodiesel agent: Identification of fatty acid methyl esters via microwave-assisted direct in situ transesterification.

Bioenergy Res 2018 Sep 12;11(3):528-537. Epub 2018 May 12.

Department of Biology, Morgan State University, 1700 East Cold Spring Lane, Baltimore, Maryland 21251, United States.

Increasing concerns on environmental and economic issues linked to fossil fuel use has driven great interest in cyanobacteria as third generation biofuel agents. In this study, the biodiesel potential of a model photosynthetic cyanobacterium, , was identified by fatty acid methyl esters (FAME) via direct transesterification. Total lipids in wild type (Fd33) and halotolerant (HSF33-1 and HSF33-2) strains determined by gravimetric analysis yielded 19% cellular dry weight (CDW) for HSF33-1 and 20% CDW for HSF33-2, which were comparable to Fd33 (18% CDW).

Dry Matter Losses and Greenhouse Gas Emissions From Outside Storage of Short Rotation Coppice Willow Chip.

Bioenergy Res 2016;9:288-302. Epub 2015 Oct 29.

Department of Agro-Ecology, Rothamsted Research, Harpenden, Hertfordshire AL5 2JQ UK.

This study examined the dry matter losses and the greenhouse gas (GHG) concentrations within two short rotation coppice (SRC) willow wood chip storage heaps. One heap was built on a grassland area (East Midlands) and the other (Rothamsted) on a concrete hard standing. A series of 1- and 3-m probes were embedded in the heaps in order to retrieve gas samples for analysis, and pre-weighed net bags were positioned in the core of the heap to detect dry matter losses.

Compositional Analysis of Biomass Reference Materials: Results from an Interlaboratory Study.

Bioenergy Res 2016 Mar 29;9(1):303-314. Epub 2015 Oct 29.

Chemical Sciences Division, National Institute of Standards and Technology, 100 Bureau Drive, Stop 8390, Gaithersburg, MD 20899-8390, USA.

Biomass compositional methods are used to compare different lignocellulosic feedstocks, to measure component balances around unit operations and to determine process yields and therefore the economic viability of biomass-to-biofuel processes. Four biomass reference materials (RMs NIST 8491-8494) were prepared and characterized, via an interlaboratory comparison exercise in the early 1990s to evaluate biomass summative compositional methods, analysts, and laboratories. Having common, uniform, and stable biomass reference materials gives the opportunity to assess compositional data compared to other analysts, to other labs, and to a known compositional value.

Carbon Sequestration by Perennial Energy Crops: Is the Jury Still Out?

Bioenergy Res 2015;8:1057-1080. Epub 2015 Jan 15.

Department of Sustainable Soils and Grassland Systems, Rothamsted Research, Harpenden, Hertfordshire, AL5 2JQ UK.

Soil organic carbon (SOC) changes associated with land conversion to energy crops are central to the debate on bioenergy and their potential carbon neutrality. Here, the experimental evidence on SOC under perennial energy crops (PECs) is synthesised to parameterise a whole systems model and to identify uncertainties and knowledge gaps determining PECs being a sink or source of greenhouse gas (GHG). For and willow ( spp. Read More

Effects on Lignin Structure of Coumarate 3-Hydroxylase Downregulation in Poplar.

Bioenergy Res 2012;5(4):1009-1019

Department of Wood Science, University of British Columbia, Vancouver, BC V6T 1Z4 Canada.

The lignin structural ramifications of coumarate 3-hydroxylase (C3H) downregulation have not been addressed in hardwoods. Such information is required to accompany an assessment of the digestibility and bioenergy performance characteristics of poplar, in particular. Structurally rich 2D NMR methods were applied to the entire lignin fraction to delineate lignin -hydroxyphenyl:guaiacyl:syringyl (H:G:S) levels and linkage distribution changes (and to compare with traditional degradative analyses).

Breeding for Bio-ethanol Production in L.: Association of Allelic Variation with High Water-Soluble Carbohydrate Content.

Bioenergy Res 2012;5(1):149-157

Institute of Biological, Environmental and Rural Sciences, Aberystwyth University, Gogerddan, Aberystwyth, Ceredigion SY23 3EB UK.

Increasing the extractable sugar yield from perennial crops is one strategy to generate renewable fuels such as bio-ethanol. L. (perennial ryegrass) can contain significant (>30% dry matter) water-soluble sugars in the form of polymeric fructan which is readily extracted, broken down and fermented to bio-ethanol. Read More
