    Description / Table of Contents: In the climate change discussion, non-CO2 greenhouse gases (NCGGs) received official political recognition for the first time in 1997, when agreement was reached on the Kyoto Protocol. As a result methane, nitrous oxide, HFCs, PFCs and SF6 now provide attractive options for detailing the national targets for the reduction of greenhouse gas emissions meant to control climate change. This book is the second volume in this area and addresses three main topics. Firstly, it documents progress with respect to our knowledge of the sources and sinks of NCGGs. Information on this subject is essential in order to reduce the uncertainties in national emissions inventories which serve as the reference values for commitments of countries in the framework of the Kyoto Protocol. Secondly, this volume deals with the control options for the NCGGs and contains a wealth of information in this area. Emerging technologies here provide business opportunities, in particular in connection with the flexible mechanisms for mitigation projects in developing countries which have been agreed in Kyoto. Thirdly, the book treats the policy implementation of mitigation options for greenhouse gas emissions. Tools for control policies, both on the national and international level, and for different sectors of industry are discussed. National integrated approaches, including the ones from the United States Environmental Protection Agency and the Netherlands Ministry of Environment which both sponsored the conference, provide guidance for defining the most effective greenhouse gases mitigation plans in different situations. This volume is being published in support of the IPCC Process and will serve as a reference for IPCC's Third Assessment Report.

    Notes: Abstract  In this paper, we review the work done in forensic toxicological analysis during about the last 30 years in Europe and to some extent in other parts of the world to assure the quality of toxicological investigations. Guidelines for carrying out toxicological analyses set up by professional bodies in the United States (AAFS/SOFT), Europe (GTFCh) and worldwide (TIAFT) are mentioned, and the problems of complying with the regulations set up in EN 45 000/ISO 9000 are discussed in detail. There are still diverging opinions as to whether toxicological laboratories should comply with good laboratory practice or with EN 45 000, and, as fas as Germany, Switzerland and Austria are concerned, a working group of the GTFCh is discussing which procedure should be adopted. Apart from having this discussion, the group aims to standardize suitable methods and is planning the organization of suitable round robins.

    Notes: Abstract The CcmH protein of Escherichia coli is encoded by the last gene of the ccm gene cluster required for cytochrome c maturation. A mutant in which the entire ccmH gene was deleted failed to synthesize both indigenous and foreign c-type cytochromes. However, deletion of the C-terminal hydrophilic domain homologous to CycH of other gram-negative bacteria affected neither the biogenesis of indigenous c-type cytochromes nor that of the Bradyrhizobium japonicum cytochrome c 550. This confirmed that only the N-terminal domain containing a conserved CXXC motif is required in E. coli. PhoA fusion analysis showed that this domain is periplasmic. Site-directed mutagenesis of the cysteines of the CXXC motif revealed that both cysteines are required for cytochrome c maturation during aerobic growth, whereas only the second cysteine is required for cytochrome c maturation during anaerobic growth. The deficiency of the point mutants was complemented when 2-mercapto-ethanesulfonic acid was added to growing cells; other thiol compounds did not stimulate cytochrome c formation in these strains. We propose a model for the reaction sequence in which CcmH keeps the heme binding site of apocytochrome c in a reduced form for subsequent heme ligation.

    Notes: Abstract The genome of the slow-growing Bradyrhizobium japonicum (strain 110) was mutagenized with transposon Tn5. A total of 1623 kanamycin/streptomycin resistant derivatives were screened in soybean infection tests for nodulation (Nod) and symbiotic nitrogen fixation (Fix). In this report we describe 14 strains possessing a stable, reproducible Nod+Fix- phenotype. These strains were also grown under microaerobic culture conditions to test them for free-living nitrogen fixation activity (Nif). In addition to strains having reduced Fix and Nif activities, there were also strains that had reduced symbiotic Fix activity but were Nif+ ex planta. Analysis of the genomic structure revealed that the majority of the strains had a single Tn5 insertion without any further apparent physical alteration. A few strains had additional insertions (by Tn5 or IS50), or a deletion, or had cointegrated part of the vector used for Tn5 mutagenesis. One of the insertions was found in a known nif gene (nifD) whereas all other mutations seem to affect different, hitherto unknown genes or operons. Several mutant strains had an altered nodulation phenotype, inducing numerous, small, widely distributed nodules. Light and electron microscopy revealed that most of these mutants were defective in different stages of bacteroid development and/or bacteroid persistence. The protein patterns of the mutants were inspected by two-dimensional gel electrophoresis after labelling microaerobic cultures with l-(35S)methionine. Of particular interest were mutants lacking a group of proteins the synthesis of which was known to be under oxygen control. Such strains can be regarded as potential regulatory mutants.
