ON A NEW FLAVIN MONONUCLEOTIDE PRODUCED BY RHIZOPUS ORYZAE

Flavin mononucleotide enzyme electrode amplified by a bioelectrocatalytic cycle.

Purification of flavin mononucleotide-dependent enzymes by column chromatography on flavin phosphate cellulose compounds.

The chemical syntheses of monoand dimethyl esters of riboflavin phosphate were accomplished by allowing riboflavin to react with the appropriate monoand dimethylchlorophosphoric acids. Riboflavin monomethyl phosphate was found to be coenzymatically active with nicotinamide adenine dinucleotide phosphate-cytochrome c aporeductase, pyridoxine (or pyridoxamine) phosphate apooxidase, and glycolate ...

A biomimetic redox flow battery based on flavin mononucleotide

The versatility in design of redox flow batteries makes them apt to efficiently store energy in large-scale applications at low cost. The discovery of inexpensive organic electroactive materials for use in aqueous flow battery electrolytes is highly attractive, but is thus far limited. Here we report on a flow battery using an aqueous electrolyte based on the sodium salt of flavin mononucleotid...

An unusual case of nasal mucormycosis caused by Rhizopus oryzae in a German shepherd dog

This study represents an unusual case of mucormycosis localized in nasal cavity of a German shepherd dog. The patient was a 1-year-old male guard dog with unilateral nasal epistaxis, mucopurulent nasal discharge, sneezing and nose pawing. The dog had a history of head trauma about 2 months before admission, which was associated with mild self-limited epistaxis. Initial nasal rhinoscopy showed s...

Subcutaneous mucormycosis caused by Rhizopus oryzae probable nosocomial acquired infection.

The Authors present a case of subcutaneous mucormycosis occurring in a patient with clinical and biochemical evidence of diabetic ketoacidosis. The clinical, mycological and histopathological features are described, emphasizing the relevance of a rapid diagnosis in order to stablish early treatment. The clinical forms of mucormycosis and the main associated conditions are briefly reviewed as we...
