    Description: The main objective of AIRP-SD was to address the urgent need to stimulate innovation in Research, Technological development and Demonstration (RTD) processes in order to enhance the prospects of RTD contributing positively to processes and strategies leading to radical improvements in the sustainability of production-consumption systems. This Milestone One Report was the first of three status reports, summarising the interim findings of the first three work packages since the start of the project in January 2002.

    Notes: Abstract Thirty-three wild type strains of Rhodopseudomonas capsulata were examined for ability to engage in genetic recombination through mediation by “gene transfer agent” (GTA) particles. The genetic exchange assays were based on capacity of strains to produce or receive GTA required for restoration of photosynthetic growth competence to a non-photosynthetic “white” mutant or for acquisition of resistance to rifampicin. A majority of the strains could either produce or receive GTA, and it was demonstrated that the agent is species specific. Possible relations between GTA and bacteriophages or bacteriocins were investigated. Sixteen types of virulent phages active on Rps. capsulata were isolated and their host ranges determined. Tests for transduction by the phages gave uniformly negative results. The viruses showed strict species specificity, but there was no apparent correlation between capacity of the Rps. capsulata strains to donate or receive GTA and susceptibility to the phages. A comparable survey disclosed that most of the bacterial strains were sensitive to or capable of producing bacteriocins; the latter also appear to be unrelated to GTA activity. The collection of bacterial strains was also screened for detection of lysogenic properties. None of the isolates is a “true” lysogen, but phages were detected in cultures of two strains, which may be “phage carriers” or pseudolysogens.

    Notes: Abstract Thirty-three strains of Rhodopseudomonas capsulata have been studied in order to develop a more comprehensive characterization of the species. On the basis of morphological, nutritional, physiological and other properties, the characteristics of an “ideal biotype” have been defined, which can be used to distinguish Rps. capsulata from similar purple bacteria. In this connection, two properties of Rps. capsulata are of particular note: a) sensitivity to penicillin G is 103–105 times greater than that shown by closely related species, and b) all strains examined are susceptible to lysis by one or more strains of host species-specific virulent bacteriophages. It appears that members of the species Rps. capsulata form a stringent taxonomic grouping.

    Notes: [Auszug] Mutants of Rps. capsulata unable to fix N2 were isolated from wild type strain BIO (obtained from Dr B. Marrs; see ref. 4) as follows. Cells were grown photosynthetically (anaerobically) at about 30 C in a synthetic medium containing DL-malate and 0.1 % ammonium sulphate as the carbon and nitrogen ...

    Notes: Abstract In this paper, we propose a methodology, based on materials accounting and operational research techniques, to assess different industry configurations according to their life cycle environmental impacts. Rather than evaluating a specific technology, our methodology searches for the feasible configuration with the minimum impact. This approach allows us to address some basic policy-relevant questions regarding technology choice, investment priorities, industrial structures, and international trade patterns. We demonstrate the methodology in the context of the European pulp and paper industry. We are able to show that current environmental policy's focus on maximizing recycling is optimal now, but that modest improvements in primary pulping technology may shift the optimal industry configuration away from recycling toward more primary pulping with incineration. We show that this will have significant implications for the amount and type of environmental damage, for the location of different stages in the production chain, and for trade between European member states. We caution policy makers that their single-minded focus on recycling may foreclose investment in technologies that could prove environmentally superior. Finally, we hint that member state governments may be fashioning their environmental policy positions at least in part on some of the trade and industrial implications we find.
