IB PRIME COMPETITION (OCTOBER 2018) WINNING PROJECT: CELTIC RENEWABLES AND NAPIER UNIVERSITY

Isolation and Characterisation of Solventogenic Clostridial Strains from Renewable Sustainable Substrates

Solventogenic clostridia have the ability to convert various biomass waste streams and low value residues into chemicals such as Acetone, Butanol and Ethanol (ABE). Success of the ABE industry relies on sustainable feedstocks and multiple robust strains capable of high productivity and feedstock utilisation. The industrial partner Celtic Renewables (CRL) employs a circular economy principal, producing ABE and high protein animal feed via fermentation of distillery by-products (draff and pot ale) and other sustainable feedstocks such as rejected potatoes.

Isolation of a novel proprietary strain could add further competitiveness and value to Scotland’s remerging ABE industry. A prospective place to isolate such strain would be from rejected potatoes and associated field soil. These strains have the potential to be specifically adapted for potato utilisation and thus for superior performance in potato fermentations. The project aims to isolate then characterise novel strains for improved feedstock utilisation and productivity.
