Zwei homoleptische Kupfer(II)-Komplexe [Cu(L1)2] und [Cu(L2)2] mit anionischen redoxaktiven Liganden wurden synthetisiert, einer dem Harnstoffazin-Ligand (L1) der andere Thioharnstoffazin-Ligand (L2). Die Einelektronen-Oxidation Komplexe löst einen seltenen redox-induzierten Elektronentransferprozess aus, welcher zu den monokationischen Kupfer(I)-Komplexen [Cu(L1)2]+ [Cu(L2)2]+ zwei oxidierten ...

In this study, it was aimed to investigate that the effect of drying process on rainbow trout (Oncorhynchus mykiss Walbaum, 1792) roes in terms proximate composition, aw, pH, TVB-N, TBARs, microbiological counts and color parameters. Drying lasted 42 hours including, 18 at 30oC 24 45oC. The dried fish were vacuum-packed (vacuum degree 0.02MPa) stored 4oC for 90th days. crude lipid, protein, ash...

A DNA genomic library constructed from Bacillus stearothermophilus, a gram-positive, facultative thermophilic aerobe that secretes a thermostable b-mannanase, was screened for mannan hydrolytic activity. Recombinant b-mannanase activity was detected on the basis of the clearing of halos around Escherichia coli colonies grown on a dye-labelled substrate, Remazol brilliant blue-locust bean gum. T...

As an obligate aerobe, Mycobacterium tuberculosis uses its electron transport chain (ETC) to produce energy via oxidative phosphorylation. This pathway has recently garnered a lot of attention and is a target for several new antimycobacterials. We tested the respiratory adaptation of M. tuberculosis to phenoxyalkylbenzimidazoles (PABs), compounds proposed to target QcrB, a component of the cyto...

Anthrax is an infectious zoonotic disease. It is transmitted to humans via infected animals and infected animal products. It was estimated that worldwide between 20,000 and 100,000 cases occurred annually. Anthrax can be seen in Africa, Central America, Albania, Central Asia, the Middle East, Spain, Greece, Romania, and Turkey. Anthrax is rare in the United States and Canada. The prevalence is ...

In aerobic, circumneutral environments, the essential element Fe occurs primarily in scarcely soluble mineral forms. We examined the independent and combined effects of a siderophore, a reductant (ascorbate), and a low-molecular-weight carboxylic acid (oxalate) on acquisition of Fe from the mineral hematite (alpha-Fe(2)O(3)) by the obligate aerobe Pseudomonas mendocina ymp. A site-directed Delt...

The effects of Orbit sugar-free chewing gum in plaque acid attack neutralisation, food debris removal, and saliva secretion rate stimulation, have already been clinically proven. Sugar alcohols, which have since recently been considered to have a direct impact on bacterial cells, are among the ingredients of this chewing gum. The objective of this study was to gain knowledge of the effects of O...

Infectious disease accounts for the major cause of mortality and morbidity in past decays which create a serious and growing concern to treat communicable disease. P. aeruginosa ‘superbug’ responsible for hospital acquired nosocomial infections is versatile gram negative aerobe and pathogenecity caused by this ubiquitous organism is quite difficult to treat due to its rapid developing inherent ...

Sunnnary-Tooth surface plaque was removed from 11 institutional~ed individuats and cultured on agar plates in an anaerobic chamber. The recovery of organisms on a dilute trypticase yeast extract medium (MMIO), incubated anaerobically, averaged 33 & 26 per cent of the microscopic count. Growth on MMlO, under aerobicconditions averaged 8 i: 5 per cent. The anaerobe to aerobe recovery ratio on med...
