The thin pili of acinetobacter sp. strain BD413 mediate adhesion to biotic and abiotic surfaces

Article Abstract:

The thick and thin pile are found in members of the genus acinetobacter and to characterize the role of different pili in the physiology of Acinetobacter the thin pile was isolated from the cell surface of Acinetobacter sp. strain BD413. The study provided clear evidence that the thin pili re not essential for motility on solid surfaces but for adhesion to hydrophobic surfaces.

Poly(3-hydroxybutyrate) (PHB) depolymerase PhaZa1 is involved in mobilization of accumulated PHB in Ralstonia eutropha H16

Article Abstract:

Four candidate genes of poly(3-hydroxybutyrate) (PHB) representing the four classes are selected and the physiological function of the gene products with recombinant Escherichia coli strains and with Ralstonia eutropha null mutants are examined. The evidence is given for weak but significant PHB depolymerase activity of PhaZha1.

Poly(3-hydroxybutyrate) granules at the early stages of formation are localized close to the cytoplasmic membrane in Caryophanon latum

Article Abstract:

The confocal laser scanning fluorescence microscopy of Nile read-stained cells and by transmission electron microscopy (TEM) are used to determine the localization of newly synthesized poly(3hydroxybutyrate) (PHB) granules. The results have shown that newly synthesized PHB granules are close with the cytoplasmic membrane.
