Two case studies will be used during the training. The participant will receive an abridged description of the case study as well as links to background information and the data-set that will be used during the practical sessions. The main differences with the respect to editions of this course offered at previous IAIA conferences are:

View similar case studies Summary of the impact University of Huddersfield research into the microbial production and metabolism of polysaccharides has had a significant impact in two distinct areas.

In the food and health care industry it has driven developments in the use of bacterial starter cultures, leading to the adoption of new techniques to produce fermented products with proven functionality.

In the policy arena, in modelling gas production by microorganisms, it has made a major contribution to the safety case for the disposal of nuclear waste, highlighting the economic and environmental benefits of underground storage.

In each instance the reach of the research's impact has been international with the biggest beneficiaries residing in Europe and North America.

Underpinning research An understanding of the potential health benefits associated with probiotic bacteria has led to commercial interest in related research. Work by the University of Huddersfield's Department of Biological Sciences has focused on relating the biological activity of the polysaccharides secreted by probiotic organisms exopolysaccharides — EPSs to their structure and, working with international collaborators, to correlate variation in EPS structures with changes in the sequence of the EPS synthesis genes.

This work is only possible because of our development of methods for production and isolation of pure EPSs for use in characterization studies and in measurement of biological activity [1, 2, 3].

Huddersfield's early Case study analysis nuclear decommissioning authority in this area were funded by two large European Framework grants, spanning to [G1, G2].

Rhodia and Biolacta's focus was on the development of EPS cultures with specific functionality-texture attributes. InDr Paul Humphreys Senior LecturerReader in Microbiology joined the research team and work was extended to include probiotic strains of bifidobacteria.

New characterization techniques were developed including real-time measurement of polysaccharide chain length. The probiotic team at IPLA-CSIC is recognized as one of the leading government funded research groups studying the biological activity and genetics of bifidobacteria.

With IPLA, the Huddersfield microbiology team has jointly published work describing both the gene sequence and the structure of an EPS from a bifidobacterium [3].

In related research, the team has also used its expertise to study microbial polysaccharide metabolism — particularly gas and small molecule generation during microbial-catalysed cellulose decomposition. This work, initiated by Humphreys in and carried out by both Humphreys and Laws sincehas helped provide a comprehensive understanding of the fate of cellulosic materials in waste facilities, which is widely regarded as a key factor in the safety case for proposed underground nuclear waste repositories.

The research investigated the microbial production of highly mobile gases such as methane, carbon dioxide and hydrogen. Being radioactive and highly flammable, these gases pose a threat to the safe storage of intermediate and low-level radioactive waste if directly released into the environment [4] The team also studied the production and subsequent fate of small organic molecules, generated during cellulose hydrolysis, that can complex with radionuclides and potentially escape into the geosphere through water courses.

The UK Nuclear Decommissioning Authority released a study analysing the economics of various management options for the UK uranium and plutonium stockpile. The stockpile comprises: 25, t U in depleted UF 6 tails from enrichment of natural uranium. However, the Nuclear Decommissioning Authority’s (NDA) remit does not extend to consideration of new nuclear power stations (NDA ). When formulating a management strategy for the UK’s plutonium stockpile, the Government must.

The principal outcome was a computational model, developed by Humphreys [6a, b], for estimating gas production during the microbial decomposition of cellulosic waste. Carbohydrate Research, 17 Gas Generation and Transport Code Canada: The work on exopolysaccharide production was supported by either the European Community or directly by European Research institutes with Huddersfield coordinating the work of Internationally recognised research teams [Grants to Marshall and Laws G1-G3].

The work on microbial gas production has been supported by government funding agencies in Canada and Europe, again, demonstrating the international excellence of our research outputs G4-G6. Details of the impact Huddersfield's research into the microbial production and metabolism of polysaccharides has had a significant impact in two distinct areas.

Firstly, research into EPS production has impacted on manufacturing industry, both the dairy industry and manufacturers of personal care products, where it has driven developments in the use of bacterial starter cultures.

Secondly, work on microbial gas production has impacted the policy arena surrounding the disposal of nuclear waste, where it has informed the debate on safety and helped deliver economic and environmental benefits. Throughout the impact period the methods established for screening LAB cultures for EPS production have been adopted by industry.

Initially applied to fermented milks, the techniques are now used for various fermented products with functional properties.

For example the personal care industry has recruited EPSs as agents for modifying the viscosity and performance of personal care products.

The work has also guided government research organisations outside the UK. A number of patents have also cited the research, including United States patent number US B2, which was granted in January to Luc De Vuyst and Bart Degeest, of Vrije Universiteit Brussel, for a method for preparing yoghurt and other fermented milk products using a starter culture with an EPS-producing micro-organism [C].

A number of agencies with responsibility for developing the safety case for proposed underground storage facilities for nuclear waste have drawn on Huddersfield's expertise in modelling the microbial decomposition of cellulose and gas generation. As a result, Huddersfield's work has helped shaped UK and Canadian government policy in this increasingly important area.

Huddersfield's work has been crucial to what OPG has described as "a thorough, traceable, step-wise assessment process" to identify the potential environmental repercussions of all phases of the project. Humphreys' modelling has helped to demonstrate the likely effects of microbial decomposition in the years following closure, leading to the conclusion that the repository will take "hundreds of thousands or even millions of years" to re-saturate.

A public hearing into the project, which was the first of its kind in Canada, took place in September If approved, the DGR is expected to be operational by In the UK the NDA has suggested the building of such facilities will bring about not just major environmental benefits but considerable economic impacts.

It has been estimated that the initial work to investigate the potential geology at a selected candidate site would require an average of around staff and take around 10 years to complete; construction would require staff; and operation would require staff. Huddersfield's work in this field is therefore helping to lay the foundations for what experts believe will be a major new industry.
