Periplasmic space is the key location for Pb(II) biomineralization by Burkholderia cepacia

Journal of Hazardous Materials, 2022
Phosphate solubilizing bacteria (PSB) induced phosphate precipitation is considered as an effective method for Pb(II) removal through the formation of stable Pb(II)-phosphate compound, but the location of end-products is still unclear. Herein, the PSB strain of Burkholderia cepacia (B.

The charasome periplasmic space

Protoplasma, 1981
Charasome structure, with special attention to the periplasmic space, is examined using various techniques. The periplasmic space appears electron lucent in sections stained with 2% aqueous uranyl acetate and lead citrate. When sections are stained with saturated methanolic uranyl acetate a densely staining central core can be seen within the ...

Expression in periplasmic space of Shewanella oneidensis

Protein Expression and Purification, 2007
A Shewanella expression system has been used for an overproduction of c-type multiheme proteins. The proteins were exported to the periplasmic space for the maturation. Since the periplasmic expression system is attractive, especially for protease-sensitive proteins, an expression vector containing a signal peptide was constructed for expressions in ...

Periplasm, Periplasmic Spaces, and Their Relation to Bacterial Wall Structure: Novel Secretion of Selected Periplasmic Proteins from Pseudomonas aeruginosa .

Microbial Drug Resistance, 1996
ABSTRACT A brief overview of thin sections of cryopreserved walls from select eubacteria will be presented to suggest that all bacteria have functional periplasms, but that these are not necessarily confined to a periplasmic space such as found in typical gram-negative bacteria.

Multilayered Distribution of Peptidoglycan in the Periplasmic Space of Escherichia coli

Microbiology, 1989
When a staining technique using phosphotungstic acid (PTA) in 10% (w/v) chromic acid was applied to cells of Escherichia coli, the periplasmic space was seen as a dark 15-nm-thick layer of uniform appearance and constant width. Our observations are consistent with peptidoglycan being the main material stained.

Periplasmic Space and Rigid Layer

2002
The region between cytoplasmic and outer membrane of the Gram-negative bacteria is called the periplasmic space. It contains a concentrated gel-like matrix, the periplasm. Embedded in it is a rigid layer (peptidoglycan). Its width has been electron microscopically determined as 13–25 nm, a variation range that may be explained by differences in ...

The Biophysics of the Gram-Negative Periplasmic Space

Critical Reviews in Microbiology, 1998
When subject to an osmotic 'up-shock', water flows outward from bacterial cytoplasm of the bacterium. Lipid bilayers can shrink very little in area and therefore must wrinkle to accommodate the smaller volume. The usual consequence is that all the layers of the cell envelope must become wrinkled together because they adhere to each other and must now ...

Glycan ligation reactions in the periplasmic space

2020
The biosynthesis pathways of bacterial glycoconjugate molecules, especially of those molecules that traffic across the cytoplasmic membrane and reside extracytoplasmically has biologically conserved features including the saccharides are formed as lipid-linked glycans anchored to cell membranes, the lipid anchors are polyisoprenoid phosphates, and the ...

Secretion into the bacterial periplasmic space of chicken ovalbumin synthesized in Escherichia coli

Gene, 1981
Ovalbumin is secreted by the tubular gland cells without cleavage of a signal sequence at the N-terminus. In Escherichia coli strains which produce a chicken ovalbumin-like protein (OLP) from a plasmid-cloned gene, the OLP is synthesized on membrane-bound polysomes and secreted without cleavage into the periplasmic space. In contrast, a deleted protein,
