Iron is an essential metal for virtually all organisms. Iron acquisition is well characterized for various organisms, whereas intracellular iron distribution is poorly understood. In contrast to bacteria, plants, and animals, most fungi lack ferritin-mediated iron storage but possess an intracellular siderophore shown to be involved in iron storage. Here we demonstrate that deficiency in the in...

Abstract This work aims to investigate the role played by a model Mn-oxidizing bacterial strain and its exudates on alteration of Mn-bearing potash-lime silicate glasses representative medieval stained glass windows. Two glasses, with or without manganese, were prepared used for abiotic Pseudomonas putida inoculated dissolution experiments. Results show that presence P. slows down kinetics whil...

The potential iron siderophore transporter genes have been determined from the genome sequence of Streptomyces coelicolor A3(2). One of these gene clusters, cdtABC, was disrupted and characterized to determine its role in the uptake of the siderophores produced by S. coelicolor. Resistance to the siderophore-like antibiotics, salmycin and albomycin, was tested in the parent and cdtABC mutant, s...

Urinary tract infection is most frequently found bacterial in urinary of human beings and 75-95% infections are caused by uropathogenic . The bacteria produces several virulence factors, siderophore one them. Siderophore iron acquisition protein play significant role pathogenicity UTI’s helping to persist host cells adverse conditions. study was conducted at SRL laboratory Ujjain Center from No...

The structure of a citrate siderophore named achromobactin isolated from the culture medium of Erwinia chrysanthemi was elucidated by spectroscopic methods and chemical degradation.
