    Notes: Recent accounts of the significance of consumption and commodities in the constitution of femininity have stressed the fluidity of consumption practices and the indeterminacy of their meaning for the oppression of women. The role of place in the construction of femininity has not been considered in these accounts, and as such uni-dimensional portraits of the consumption-femininity nexus have prevailed. In this article I offer an alternative place-based account of the construction of femininity through consumption, demonstrating the constitution of gendered relations of consumption in place. In so doing, some of the contradictions in the consumption-femininity nexus are highlighted. Using a case study of one facet of consumption - retailing - I demonstrate the importance of place and context in the construction of femininity through consumption, in three substantive ways. First, the selling of commodities by retail institutions entails the creation of place. Second, the construction of femininity - shopping as an important component of domestic labor and shopping as feminine, is part of this creation of place. Third, this environment and the process of shopping influence the meaning of commodities and associated constructions of femininity.

    Notes: Abstract In order to validate unusual fatty acids as biomarkers for sulphate-reducing bacteria, selective conditions were arranged for the enrichment of a marine glutamate-fermenting bacterium which made hydrogen and acetate available for oxidation via the respiration of sulphate. Under these conditions the complete oxidation of glutamate via sulphate reduction accounted for 84% of the available electron equivalents. Fatty acid biomarkers for hydrogen-oxidizing Desulfovibrio sp. (iso 17:1w7c and branched monoenoics) and for acetate-oxidizing Desulfobacter (10 methyl 16:0) were detected in the enrichment. These biomarkers were demonstrated in pure cultures of Desulfovibrio sp. and Desulfobacter sp. obtained from the enrichment. The predominant glutamate-fermenting bacterium isolated from the consortium contained no branched ester-linked phospholipid fatty acids, and produced acetate and hydrogen. With energy limitation the enriched consortium produced increased amounts of extracellular polysaccharide and the endogenous storage lipid poly-beta-hydroxybutyrate as detected with Fourier transform/infra-red (FT-IR) spectroscopy.

    Notes: The bphK gene encoding glutathione S-transferase (GST) is located in the bph operon (PCB co-metabolism) in Burkholderia sp. strain LB400 and the enzyme has recently been shown to have dechlorination activity in relation to 4-chlorobenzoate (4-CBA). Alignments using other glutathione S-transferase sequences found in PCB degradation operons identified a highly conserved region in the C-terminal domain of these enzymes that included a conserved motif implicated in protein folding in eukaryotic GSTs. Site-directed mutagenesis indicated that the region is indirectly involved in the catalytic activity and substrate specificity of BphK. Predicted hydrogen bond interactions involving Asp155 play an important role in the enzymatic properties of this glutathione S-transferase.

    Notes: Abstract Broad host-range RK2-based cosmid vectors (‘costramids’) are increasingly used in molecular genetic studies of Gram-negative soil bacteria such as Rhizobium spp. we describe a simple modification of existing methods, whereby a genomic library constructed in a stringently replicated vector can be screened for genes which are undetectable by colony hybridization due to background cross-hybridization. This method allows the use of ‘heterologous’ probes (interspecies hybridization) to isolate several presumptive genes of interest from a gene bank of Rhizobium sp. NGR234 made in the costramid pRK7813. These are a gene with homology to the citrate synthase gene (gltA) or Escherichia coli, the gene encoding δ-aminol evulinic acid synthase (hemA), and a gene or genes regulating dicarboxylate transport.

    Notes: Abstract The iron-regulated PbrA sigma factor dictates the production of the siderophore, pseudobactin Ml 14, and its cognate outer membrane receptor, PbuA, in Pseudomonas fluorescens M114. However, the siderophore molecule also has a role in regulating the expression of the siderophore biosynthetic and siderophore receptor genes in P. fluorescens M114. This is based on the fact that β-galactosidase levels from lacZ fusions of M114 siderophore promoters (biosynthetic and receptor) were reduced in M114 siderophore biosynthetic mutants compared to wild-type M114. Expression of both promoters was increased by the addition of pseudobactin M114 to the growth medium. This effect was widespread and applicable to all but one of the siderophore negative strains of M114 tested. Furthermore, it was demonstrated that transcription of the pbrA sigma factor gene was not reduced in the siderophore biosynthetic mutants. This excludes the possibility that reduced expression of the siderophore biosynthetic and receptor promoters in the siderophore biosynthetic mutants is mediated at the level of expression of the pbrA gene itself. In addition, it was noted that the siderophore regulated response was applicable to promoters with and without the DNA sequence motif, (G/C)CTAAATCCC, which is required for iron-regulated expression of some pseudomonad promoters.

    Notes: Abstract In this report we describe the development and construction of a DNA module which encodes bph genes for the metabolism of PCBs and which is capable of stable integration into the chromosome of Gram negative bacteria. Introduction of the bph-module into Pseudomonas putida KT2442, Pseudomonas sp. strain B13 and its genetically engineered derivative B13FR1 expanded the biodegradative ability of these strains to include biphenyl and 4-chlorobiphenyl. The bph operon was stably inherited under laboratory conditions. Behavior of the genetically engineered strains was evaluated under simulated natural habitat conditions in lake sediment microcosms with respect to survival and removal of 4-chlorobiphenyl. The genetically engineered strains persisted under these conditions and were effective in degrading 4-chlorobiphenyl over a five day incubation period.

    Notes: SUMMARY— The sensory and stability properties of neohesperidin dihydrochalcone were evaluated. Combinations of neohesperidin dihydrochalcone with saccharin and cyclamate were tested for their effect on taste qualities in soft drink type products. A mixture in which neohesperidin dihydrochalcone contributed 25% of the total sweetness (saccharin 64% and cyclamate 11%) gave a taste sensation that was considered to be of good quality. Tests indicated that the presence of neohesperidin dihydrochalcone gave, for most tasters, an apparent increase in flavor. The ethoxy homolog, homoneohesperidin dihydrochalcone, gave the same effect as the neohesperidin dihydrochalcone.The stabilities of neohesperidin dihydrochalcone under a variety of conditions of manufacture, storage and use were studied. Research showed that the glycosidic compound was resistant to hydrolysis of the sugar moieties in solutions of various acids above pH 2 at normal temperatures.
