Acoustic backscatter strength and turbulence data from Vobster Quay (24-28 June 2016)

The dataset provides backscatter strength data from a 500-kHz ADCP by Nortek deployed in Vobster Quay, a 40-m quarry in South-West England (UK). Acoustic data shows the Diel Vertical Migration of small zooplankton at dusk and sunrise on 24-28 June 2016. The dataset also contains 10 turbulence profiles acquired with a microstructure profiler (SCAMP, manufactured by PME) in the same lake during the day. The ensemble-averaged profile shows small dissipation of turbulent kinetic energy in the lake interior, where turbulence is generally suppressed by the summer temperature stratification. Note: This dataset was originally published for a draft of the paper "Can small zooplankton mix lakes?" in Limnology and Oceanography Letters (DOI: 10.1002/lol2.10047). However, the final version of the paper does not refer any more to this dataset. Access to the data is still available upon request

WBE - European multi-city study

The project in question analysed wastewater in over 60 European cities and towns (hereinafter referred to as ‘cities’) to explore the drug-taking habits of those who live in them. The results provide a valuable snapshot of the drug flow through the cities involved, revealing marked geographical variations

Cross-metathesis of microbial oils for the production of advanced biofuels and chemicals

A range of microbial oils were cross-metathesized with ethene using Hoveyda-Grubbs 2nd generation catalyst. The products formed from the microbial oils were compared to alternative first and second generation oils. Upon separation, three separate fractions were produced: an alkene hydrocarbon fraction or aviation fuel fraction (AFF), a shorter chain triglyceride fraction that upon transesterification was suitable as a road transport fuel (RTF) and a volatile short-chain alkene fraction (gas phase fraction, GPF). The fuel fractions were purified through distillation and compared to the relevant fuel standards. Though there was variation for the road transport fuel fraction due to the presence of long chain saturates, all the RTF produced fell within the ASTM standard for biodiesel. The AFF was found to be highly suitable for aviation, falling entirely within the DEF-STAN fuel standard. In addition the AFF possessed a higher energy density than Jet A-1 while 1-decene was found to have a higher oxidative stability than jet fuel. Finally, the GPF was found to predominantly contain propene, butene and pentadiene isomers, all of which have application in the polymer industry. With further development, this process could provide the basis for a microbial oil biorefinery for the production of sustainable biofuels and polymer precursors

Production of lipid from depolymerised lignocellulose using the biocontrol yeast, Rhodotorula minuta: The fatty acid profile remains stable irrespective of environmental conditions

The oleaginous yeast Rhodotorula minuta has been used previously as a biocide agent and for the production of β-carotene. In addition, R. minuta has been shown to produce up to 40% lipids, while demonstrating a faster growth rate than the similar oleaginous yeasts; Lipomyces starkeyii and Rhodotorula glutinis. In this study this promising yeast was evaluated for its potential to produce glyceride lipids under the harsh conditions and complex sugar mixtures produced from depolymerised lignocellulose. The fatty acid profile of R. minuta was not found to change significantly irrespective of the environmental conditions and contained approximately 20% palmitic acid, 5% stearic acid, 60% oleic acid and 15% linolenic acid. R. minuta was found to grow on a range of sugars, and could consume xylose and glucose when both sugars were present, however, R. minuta was found to be highly sensitive to inhibitors, such as furfurals and organic acids, formed under the harsh lignocellulose depolymerisation conditions. Accordingly R. minuta did not grow well on biomass depolymerised with an acid pre-treatment stage. However, R. minuta was cultured successfully on food waste depolymerised with no additional acids, producing up to 19 g /L cell mass with a lipid content of up to 25% of the dry cell weight
