RAPD discrimination of Agaricus bisporus mushroom cultivars
RAPD analyses can assist mushroom strain identification and could play a role in the protection of novel cultivars, many of which appear to be essentially derived varieties from two original hybrid cultivars. Expand
ColV plasmid-mediated, colicin V-independent iron uptake system of invasive strains of Escherichia coli.
Evidence is presented that ColV plasmid-mediated iron uptake, an important component of the virulence of invasive strains of Escherichia coli, is independent of colicin V synthesis and activity. AExpand
Use of Lactobacillus plantarum LPCO10, a Bacteriocin Producer, as a Starter Culture in Spanish-Style Green Olive Fermentations.
Results indicated that L. plantarum LPCO10 may be useful as a starter culture to control the lactic acid fermentation of Spanish-style green olives. Expand
ColV plasmid-specific aerobactin synthesis by invasive strains of Escherichia coli.
Reconstruction experiments involving a chelator-deficient mutant growing with exogenous chelator suggested that association of a small fraction of the total siderophore synthesized with cellular material is due to transient binding of aerobactin to membrane receptors during active bacterial growth.

Purification and partial amino acid sequence of plantaricin S, a bacteriocin produced by Lactobacillus plantarum LPCO10, the activity of which depends on the complementary action of two peptides.
Plantaricin S, one of the two bacteriocins produced by Lactobacillus plantarum LPCO10, which was isolated from a green-olive fermentation, has been purified to homogeneity by ammonium sulfate precipitation, by binding to SP-Sepharose fast-flow, phenyl- Sepharose CL-4B, and C2/C18 reverse-phase chromatographies.

Molecular Analysis of the Locus Responsible for Production of Plantaricin S, a Two-Peptide Bacteriocin Produced byLactobacillus plantarum LPCO10
A third ORF, ORF5, shows homology with gene agrB from Staphylococcus aureus, which is involved in the mechanism of regulation of the virulence phenotype in this species, and anagr-like regulatory system for the production of plantaricin S is postulated. Expand
Genetics of Lactic Acid Bacteria
This chapter discusses the Genetics of Phage Resistance in Lactococcus Lactis, and the Ratio between Benefits and Risk of Fermented Foods Produced by Genetically Modified Lactic Acid Bacteria. Expand
Sphaeroplast and electroporation‐mediated transformation of Lactobacillus plantarum
Two techniques for transformation of the organism are described: firstly, sphaeroplast transformation and secondly, electroporation‐mediated transformation, which appear to be plasmid‐ and strain‐specific and therefore may be complementary in the development of genetic manipulation of this organism.

Development of a disposable pyruvate biosensor to determine pungency in onions (Allium cepa L.).
A disposable prototype pyruvate biosensor was constructed using pyruvate oxidase immobilised on mediated meldolas blue electrodes to determine pungency in onions (Allium cepa L.). The optimumExpand
