    Effect of Corn Oil and Casein on the Antimicrobial Activity of Phenolic Antioxidants (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 48 (1983), S. 0

    Notes: Several inhibitory concentrations of butylated hydroxyanisole (BHA) and tertiary butylhydroquinone (TBHQ) were tested against five microorganisms in the presence of 0, 1.5, 3.0 and 4.5% (v/v) of a lipid, corn oil, or 0, 3, 6 and 9% (w/v) of a protein, casein. In all cases, casein depressed, but did not abolish, the antimicrobial activity of BHA. However, corn oil virtually eliminated the antimicrobial properties of lethal doses of BHA. In contrast, TBHQ was affected much less by the food components than BHA, retaining considerable antimicrobial activity in most cases except with Staphylococcus aureus.

    Chemical and Nutritional Studies on Mesquite Beans (Prosopis juliflora) (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 48 (1983), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Mesquite beans (Prosopis juliflora) consisted of pericarp, hulls and kernels. With the exception of kernels, composition of beans and their fractions were protein, 10–15%; fat, 2–3%; crude fiber, 20–30%; sucrose, 21%; reducing sugars, 2–6%. Kernels contained 38% protein, 3% fat and 9% crude fiber. Bean trypsin inhibitor content was 1.4 TIU/mg. Bean protein isoelectric point was pH 5. Mesquite protein concentrate and isolate were prepared, however, by increasing solubility at the extraction pH (pH 10) with NaCl and decreasing it at the isoelectric point with (NH4)2SO4. First and second limiting amino acids for bean protein were threonine and isoleucine, respectively; the protein was high in total sulfur amino acids and tryptophan. Corrected PER was 1.4.

    Do cells treated with human interferon survive virus infection? (1983)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 20 (1983), S. 0 
    Details
    ISSN: 1574-6968
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Abstract HeLa cells pretreated with human lympho-blastoid interferon (Hu IFN-α (Ly)), at concentrations up to 100 IU / ml and infected with moderate multiplicities of encephalomyocarditis (EMC) virus (10 PFU / cell) died 1 or 2 days after infection. However, if cells were repeatedly treated with high doses of IFN (800 IU / ml) they survived infection by EMC virus for at least a month. Cells survived Semliki Forest virus (SFV) infection when even lower IFN concentrations were used. By contrast infection of IFN-treated HeLa cells with other RNA-containing viruses, such as poliovirus, vesicular stomatitis virus (VSV), Newcastle disease virus (NDV) and reovirus type 3 resulted in cell death. Similarly, infection with a number of DNA-containing viruses such as adenovirus type 5, Herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) and vaccinia virus killed cells. The results are discussed in the light of different models for the molecular mechanism of action of interferon.

    Solid state fermentation and fractionation of oat straw by Basidiomycetes (1983)
    Springer
    Applied microbiology and biotechnology 18 (1983), S. 120-123 
    Details
    ISSN: 1432-0614
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Summary Seventee white-rot and brown-rot fungi were screened for their ability to fractionate the lignocellulose structure of oat straw through the preferential attack of lignin or cellulose. Fermentations were carried out under solid-state conditions with 25 g quantities of straw. The fermented straw was analyzed for weight loss, Klason lignin loss and cellulase digestion. All the fungi attacked both lignin and carbohydrate fractions causing 3–28% weight losses and 26–34 g/100 g enzymatic digestibility. Polyporus tulipiferae, Phanerochaete chrysosporium and Polyporus sp. were tested for the effects of various nitrogen, phosphate and carbon levels, incubation temperatures and incubation time. The three fungi had different responses to these factors.

    Notes: [Auszug] SIR - In their dual aetiology hypothesis for the Spanish toxic oil syndrome1, Root-Bernstein and Westall fail to distinguish between theories and scientific facts. This is precisely one of the major problems we are encountering in Spain when dealing with the several aetiological hypotheses which ...

    Topography of the subunits of Micrococcus lysodeikticus F1-ATPase (1983)
    Springer
    Molecular and cellular biochemistry 56 (1983), S. 73-80 
    Details
    ISSN: 1573-4919
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Summary The combined use of proteolytic digestion and lactoperoxidase catalyzed labelling with [125I] applied to membrane-bound or soluble pure F1-ATPase from Micrococcus lysodeikticus has allowed us to establish the topography of its α, β, γ and δ subunits within the protein molecule and with respect to the plane of the membrane. The β subunit is most externally located to the membrane bilayer looking towards the cytoplasmic face, a position consistent with its proposed catalytic role. The α and γ subunits lie in an intermediate layer between the β subunits and the membrane, in which the γ subunit occupies a central position within the F1-ATPase molecule in contact with the α subunit. The δ subunit appears to be tightly bound to the F0 component of the ATPase complex, probably buried in the membrane bilayer. A molecular arrangement of M. lysodeikticus ATPase is proposed that, taking into account the subunit stoichiometry α3 β3 γ2 δ2 (MW 420 000), accommodates the role assigned to each subunit and most, if not all, the known properties of this bacterial energy-transducing protein.

    Binding of puromycin to E. coli ribosomes. Effects of puromycin analogues and peptide bond formation inhibitors (1973)
    Springer
    Molecular biology reports 1 (1973), S. 27-32 
    Details
    ISSN: 1573-4978
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract 3H-puromycin binds to bacterial ribosomes, in the presence of ethanol, under the experimental conditions of the fragment reaction assay. The binding is feeble, takes place at 0°C, is partially inhibited by chloramphenicol and lincomycin and totally by sparsomycin. 3H-puromycin binding is hardly affected by the 3′ aminonucleoside of puromycin, is well inhibited by the L-Phenylalanine and L-Leucine analogues of puromycin and totally blocked by L-Phenylalanyl-adenosine.

    Kinetic studies of peptide bond formation. Effect of chloramphenicol (1973)
    Springer
    Molecular biology reports 1 (1973), S. 75-79 
    Details
    ISSN: 1573-4978

    Topics: Biology
    Notes: Abstract There might be an undetermined order in the interaction of the substrates with the ribosomes in the reaction of CACCA-Leu-Ac with puromycin to form Ac-Leu-puromycin and CACCA (‘fragment reaction’). Km 0°=6×10-4 M for the puromycin · ribosome interaction. Chloramphenicol totally blocks the ‘fragment reaction’ as a consequence of a single interaction with the ribosome of Kd 0°=2.2×10-6 M. The inhibition by chloramphenicol of the ‘fragment reaction’ is mixed competitive for puromycin.
