Open Access research that shapes economic thinking...

Strathprints makes available scholarly Open Access content by the Fraser of Allander Institute (FAI), a leading independent economic research unit focused on the Scottish economy and based within the Department of Economics. The FAI focuses on research exploring economics and its role within sustainable growth policy, fiscal analysis, energy and climate change, labour market trends, inclusive growth and wellbeing.

The open content by FAI made available by Strathprints also includes an archive of over 40 years of papers and commentaries published in the Fraser of Allander Economic Commentary, formerly known as the Quarterly Economic Commentary. Founded in 1975, "the Commentary" is the leading publication on the Scottish economy and offers authoritative and independent analysis of the key issues of the day.

Abstract

Trichloroethylene (TCE) was degraded aerobically with the strain Burkholderia cepacia G4. The degradation leveled out after similar to 40 hours, while the removal efficiency depended on the optical cell density (OD540) During the experiment at an OD540 of 0.8, TCE was degraded up to 59.3%, with an isotopic difference between initial and remaining substrate of 12.3 parts per thousand. At a lower OD540 of 0.5 the amount of TCE degraded was only 40.5% and the delta(13)C(TCE) difference between initial and remaining substrate was 10.5 parts per thousand
