The pUM505 plasmid, isolated from a clinical Pseudomonas aeruginosa isolate, confers resistance to ciprofloxacin (CIP) when transferred into the standard P. strain PAO1. CIP is an antibiotic of quinolone family that used treat infections. In silico analysis, performed identify genes, revealed 65-amino-acid product encoded by orf131 gene in displays 40% amino acid identity Mycobacterium smegmatis aminoglycoside phosphotransferase (an enzyme phosphorylates and inactivates antibiotics). We...
Two chromate-resistant filamentous fungi, strains H13 and Ed8, were selected from seven independent fungal isolates indigenous to Cr(VI)-contaminated soil because of their ability decrease hexavalent chromium levels in the growth medium. Morphophysiological studies identified strain as a Penicillium sp. isolate Ed8 an Aspergillus isolate. When incubated minimal medium with glucose carbon source presence 50 µg/mL Cr(VI), these caused complete disappearance Cr(VI) after about 72 h incubation....

Abstract Mucormycosis is a fungal infection caused by Mucorales, with high mortality rate. However, only few virulence factors have been described in these organisms. This study showed that deletion of rfs , which encodes the enzyme for biosynthesis rhizoferrin, siderophore, Mucor lusitanicus led to lower diabetic mice and nematodes. Upregulation correlated increased toxicity cell-free supernatants culture broth (SS) obtained under growing conditions favor oxidative metabolism, such as low...
The gene prt1 was isolated from the tomato vascular wilt fungus Fusarium oxysporum f. sp. lycopersici, whose predicted amino acid sequence shows significant homology with subtilisin-like fungal proteinases. Prt1 is a single-copy gene, and its structure highly conserved among different formae speciales of F. oxysporum. expressed constitutively at low levels during growth on carbon nitrogen sources strongly induced in medium containing collagen glucose. As shown by reverse...
Chromium pollution is potentially detrimental to bacterial soil communities, compromising carbon and nitrogen cycles that are essential for life on earth. It has been proposed intracellular reduction of hexavalent chromium [Cr(VI)] trivalent [Cr(III)] may cause death by a mechanism involves reactive oxygen species (ROS)-induced DNA damage; the molecular basis phenomenon was investigated in this work. Here, we report Bacillus subtilis cells lacking functional error prevention oxidized guanine...
The fungus Mucor circinelloides undergoes yeast-mold dimorphism, a developmental process associated with its capability as human opportunistic pathogen. Dimorphism is strongly influenced by carbon metabolism, and hence the type of metabolism likely affects virulence. We investigated role ethanol in M.
A serendipitous one pot self-assembly synthesis of hydride CNN–Pt( iv ) pincer complexes was achieved, which involves a formal C–H bond activation, with an earlier C–N formation via C–Br excision, instead the expected rollover complex.
