Nanoparticle-mediated Impact on Growth and Fatty Acid Methyl Ester Composition in the Cyanobacterium .

Bioenergy Res 2019 Jun 8;12:409-418. Epub 2019 Mar 8.

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

Insufficient light supply is a major limitation in cultivation of cyanobacteria for scaled up biofuel production and other biotechnological applications, which has driven interest in nanoparticle-mediated enhancement of cellular light capture. In the present study, wild type (Fd33) and halotolerant (HSF33-2) strains were grown in solution with 20, 100, and 200 nm-diameter gold nanoparticles (AuNPs) to determine their impact on biomass accumulation, pigmentation, and fatty acid methyl ester (FAME) production. Results revealed a significant increase in growth of Fd33 (0. Read More

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).

In Situ Enzymatic Conversion of IMET1 Biomass into Fatty Acid Methyl Esters.

Bioenergy Res 2017 Jun 20;10(2):438-448. Epub 2016 Dec 20.

Institute of Marine and Environmental Technology, University of Maryland Center for Environmental Science and University of Maryland Baltimore County, Baltimore, MD 21202, USA.

Conventionally, production of methyl ester fuels from microalgae occurs through an energy-intensive two-step chemical extraction and transesterification process. To improve the energy efficiency, we performed in situ enzymatic conversion of whole algae biomass from an oleaginous heterokont microalga IMET1 with the immobilized lipase from . The fatty acid methyl ester yield reached 107. Read More

Bioethanol Production from Brewers Spent Grains Using a Fungal Consolidated Bioprocessing (CBP) Approach.

Bioenergy Res 2017 8;10(1):146-157. Epub 2016 Aug 8.

1Brewing Science Section, Division of Food Sciences, The University of Nottingham, Sutton Bonington Campus, Loughborough, Leicestershire LE12 5RD UK.

Production of bioethanol from brewers spent grains (BSG) using consolidated bioprocessing (CBP) is reported. Each CBP system consists of a primary filamentous fungal species, which secretes the enzymes required to deconstruct biomass, paired with a secondary yeast species to ferment liberated sugars to ethanol. Interestingly, although several pairings of fungi were investigated, the sake fermentation system ( and NCYC479) was found to yield the highest concentrations of ethanol (37 g/L of ethanol within 10 days).

Testing the Use of Static Chamber Boxes to Monitor Greenhouse Gas Emissions from Wood Chip Storage Heaps.

Bioenergy Res 2017 9;10(2):353-362. Epub 2016 Nov 9.

1Department of Agro-Ecology, Rothamsted Research, Harpenden, Hertfordshire AL5 2JQ UK.

This study explores the use of static chamber boxes to detect whether there are fugitive emissions of greenhouse gases (GHGs) from a willow chip storage heap. The results from the boxes were compared with those from 3-m stainless steel probes inserted into the core of the heap horizontally and vertically at intervals. The results from probes showed that there were increases of carbon dioxide (CO) concentrations in the heap over the first 10 days after heap establishment, which were correlated with a temperature rise to 60 °C.

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

Dry Matter Losses and Methane Emissions During Wood Chip Storage: the Impact on Full Life Cycle Greenhouse Gas Savings of Short Rotation Coppice Willow for Heat.

Bioenergy Res 2016 13;9(3):820-835. Epub 2016 Apr 13.

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

A life cycle assessment (LCA) approach was used to examine the greenhouse gas (GHG) emissions and energy balance of short rotation coppice (SRC) willow for heat production. The modelled supply chain includes cutting multiplication, site establishment, maintenance, harvesting, storage, transport and combustion. The relative impacts of dry matter losses and methane emissions from chip storage were examined from a LCA perspective, comparing the GHG emissions from the SRC supply chain with those of natural gas for heat generation.

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
