    Notes: Abstract The cpcA and cpcB genes, which encode the α- and β-subunit apoproteins of Synechococcus 7002 phycocyanin (PC), respectively, are efficiently expressed in Escherichia coli. Studies performed with a series of deletions produced from the parental plasmid pAQPR1 suggest that transcription of these genes in E. coli is initiated from a promoter located not more than 384 bp upstream from the translation start of cpcB. An examination of the nucleotide sequence of this region reveals a consensus E. coli promoter centered approx. 374 bp upstream from the cpcB translation start. The cyanelle-encoded allophycocyanin α- and β-subunit apoprotein genes (apcA and apcB) of Cyanophora paradoxa are also expressed in E. coli.

    Notes: Abstract The region of the cyanelle genome of Cyanophora paradoxa which codes for ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBis-CO) has been cloned and partially characterized. The large subunit gene (rbcL) is located adjacent to, and upstream from the small subunit gene (rbcS). The rbcS, containing 318 nucleotides, codes for a polypeptide that exhibits greater homology to small subunits of cyanobacteria than to those of angiosperms. Immediately downstream from the rbcS termination codon is an apparent transcription termination site consisting of an inverted repeat followed by a T cluster. The spacer region separating rbcL and rbcS is 105 nucleotides in length and lacks an obvious RNA polymerase promoter sequence suggesting that the genes are cotranscribed. Northern blot analysis has confirmed the cotranscription of both genes as a single transcript of approx. 2500 nucleotides.

    Storage Stability of Soybean Oil-Based Salad Dressings: Effects of Antioxidants and Hydrogenation (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 51 (1986), S. 0 
    Details
    ISSN: 1750-3841

    Notes: Flavor deterioration of salad dressings was investigated to determine the effect of hydrogenation of the oil, additives and storage conditions. Flavor quality tests were developed and correlated with gas chromatographic analyses of volatile compounds in oils separated from the dressings. Hydrogenation of soybean oil with copper and nickel catalysts effectively increased the storage stability of salad dressings at 21°C but not at 32°C. The use of BHA as an antioxidant in the oil or EDTA as a metal inactivator in the starch base as well as nitrogen packaging were effective in prolonging the storage stability of salad dressings made with unhydrogenated soybean oil. Therefore, these additives or nitrogen packaging may provide economic substitutes for hydrogenation of soybean oil used in salad dressings.

    Notes: Alaska pollock was headed, gutted, and frozen at sea in pre- and postrigor condition. Surimi made from this fish held at - 29°C showed a gradual loss in gel-forming ability with time of storage. This loss in gel-forming ability was accompanied by a loss in viscosity and Ca++-ATPase activity of the surimi over the 9-month storage period. The gel strength of kamaboko gels showed an inverse linear relationship with gel moisture over a limited moisture range. Simply freezing and thawing pollock resulted in surimi with significantly lower gel strength than that from fresh pollock.

    Flow and Containment of Injected Wastes (1986)

    Notes: Proper design, construction, testing and maintenance of Class 1 (hazardous waste) injection wells can guarantee that all waste is delivered to the injection zone. To assess the effects of waste injection, analytical models were developed which predict waste movement and pressure increases within the injection zone, and describe upward permeation through confining layers.A basic plume model was used to track waste from several injection wells with varied injection history at DuPont's Victoria Texas site. To determine the maxi-mum distance that any portion of the waste might travel, special purpose models were employed to account for (1) density differences between the waste and the native formation brine, and (2) layered permeability variation within the injection zone. The results were generalized to a “multiplying factor concept,” which facilitates development of a worst-case scenario.A pressure distribution model based on the Theis (1935) equation for radial flow was applied to the Victoria site, with modifications to account for multiple wells, injection history and geological complexities.Permeation into an intact confining layer was investigated by a new technique based on the Hantush and Jacob (1955) “leaky aquifer” theory. The model defines the maximum permeation distance, taking into account post-injection pressure decay.Defects within confining layers, such as faults, fractures and abandoned wells, have been considered. Studies to evaluate their detailed characteristics are continuing. Initial results indicate that faults and fractures are not likely to provide conductive pathways in Gulf Coast settings, and site-specific evaluations are required to assess the impact of abandoned wells.

    Protozoa in Planktonic Food Webs, (1985)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 32 (1985), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Protozoa are now being recognized as important members of planktonic food webs. This is due to the inclusion of microbial links in our paradigm of trophic relationships. Heterotrophic microflagellates and ciliates are major grazers of bacteria. They can stimulate production through nutrient recycling and can transform microbial production into larger particles, which are then available for macroconsumers. In this paper we add new groups, the small (〈 20 μm) ciliates and myxotrophic flagellates, to the planktonic food web.

    Sedimentology of an ancient erg margin: the Lower Jurassic Aztec Sandstone, southern Nevada and southern California (1987)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 34 (1987), S. 0

    ISSN: 1365-3091

    Topics: Geosciences
    Notes: The Lower Jurassic Aztec Sandstone is an aeolian-deposited quartzose sandstone that represents the western margin of the southerly-migrating Navajo-Nugget sand sea (or erg). Vertical and lateral facies relations suggest that the erg margin encroached upon volcanic highlands, alluvial fan, wadi and sabkha environments.In southern Nevada, 700 m thick facies successions record the arrival of the Aztec sand sea. Initial erg sedimentation in the Valley of Fire consists of lenticular or tongue-shaped aeolian sand bodies interstratified with fluvially-deposited coarse sandstone and mudstone. Above, evaporite-rich fine sandstone and mudstone are overlain by thick, cross-stratified aeolian sandstone that shows an upsection increase in set thickness. The lithofacies succession represents aeolian sand sheets and small dunes that migrated over a siliciclastic sabkha traversed by ephemeral wadis. These deposits were ultimately buried by large dunes and draas of the erg. In the Spring Mountains, a similar facies succession also contains thin, lenticular volcaniclastic conglomerate and sandstone. These sediments represent the distal margin of an alluvial fan complex sourced from the west.Thin aeolian sequences are interbedded with volcanic flow rocks, ash-flow tuffs, debris flows, and fluvial deposits in the Mojave Desert of southern California. These aeolian strata represent erg migration up the eastern flanks of a magmatic arc. The westward diminution of aeolian-deposited units may reflect incomplete erg migration, thin accumulation of aeolian sediment succeptible to erosion, and stratigraphic dilution by arc-derived sediment.A two-part division of the Aztec erg is suggested by lithofacies associations, the size and geometry of aeolian cross-strata, and sediment dispersal data. The leading or downwind margin of the erg, here termed the fore-erg, is represented by a 10–100 m thick succession of isolated pods, lenses, and tongues of aeolian-deposited sediment encased in fluvial and sabkha deposits. Continued sand-sea migration brought large dunes and draas of the erg interior into the study area; these 150–500 m thick central-erg sediments buried the fore-erg deposits. The trailing, upwind margin of the erg is represented by back-erg deposits in northern Utah and Wyoming.

    Molecular evolution of the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) (1986)

    Notes: Abstract The evolutionary relationship of the RuBisCO large subunit gene(s) (rbcL) of several prokaryotes was examined using the technique of heterologous DNA hybridization. Restriction fragments of cloned rbcL from Anacystis nidulans 6301, Chlamydomonas reinhardtii, Rhodospirillum rubrum, and maize were nick-translated and used as probes. The C. reinhardtii and maize probes hybridized with restriction fragment(s) only from cyanobacteria: Agmenellum quadruplicatum, Fremyella diplosiphon, and Mastigocladus laminosus. In addition, the A. nidulans probe hybridized with restriction fragment(s) from Alcaligenes eutrophus, Chromatium vinosum, Nitrobacter hamburgensis, Paracoccus denitrificans, Pseudomonas oxalaticus, Rhodomicrobium vannielii, Rhodopseudomonas capsulata, Rhodopseudomonas palustris, Rhodopseudomonas sphaeroides, Thiobacillus intermedius, Thiobacillus neapolitanus, and Thiothrix nivea. The elucidated fragment of Rhodopseudomonas species is presumably for the Form I RuBisCO LSU of these organisms. The R. rubrum probe hybridized only to a restriction fragment(s) from R. capsulata, R. palustris, R. sphaeroides, T. neapolitanus, and T. nivea. The fragment(s) of Rhodopseudomonas species is the Form II rbcL of these organisms. The restriction fragments of T. neapolitanus and T. nivea were also different from those elucidated by the A. nidulans probe, suggesting the presence of a second (different) rbcL in these organisms. Positive hybridization was not obtained using any of the probes with DNA from Beggiatoa alba, Chlorobium vibrioforme or Chloroflexus aurantiacus. It appears that all rbcL have evolved from a common ancestor. Our data are consistent with and supportive of the evolutionary scheme for RuBisCO proposed by Akazawa, Takabe, and Kobayashi [1].
