Torulopsis candida (Candida famata) Endophthalmitis Simulating Propionibacterium acnes Syndrome

Archives of Ophthalmology, 1991
Four months after undergoing extracapsular cataract extraction with implantation of a posterior chamber intraocular lens, a 74-year-old woman developed granulomatous anterior uveitis. Although she initially responded well to corticosteroid therapy, she experienced multiple recurrences on discontinuation of this therapy. Slit-lamp examination showed the

Production of flavin mononucleotide by metabolically engineered yeast Candida famata

Metabolic Engineering, 2009
Recombinant strains of the flavinogenic yeast Candida famata able to overproduce flavin mononucleotide (FMN) that contain FMN1 gene encoding riboflavin (RF) kinase driven by the strong constitutive promoter TEF1 (translation elongation factor 1alpha) were constructed.

Overexpression of Riboflavin Excretase Enhances Riboflavin Production in the Yeast Candida famata

2021
Many microorganisms are capable of riboflavin oversynthesis and accumulation in a medium, suggesting that they efficiently excrete riboflavin. The mechanisms of riboflavin efflux in microorganisms remain elusive. Candida famata are representatives of a group of so-called flavinogenic yeast species that overproduce riboflavin (vitamin B2) in response to

Biochemical responses in a Candida famata strain adapted to high copper concentrations

Biometals, 2000
A strain of Candida famata adapted to high copper concentration (1.26 mM) and a number of biochemical parameters have been tested, in order to get information on the mechanisms of metal toxicity and detoxification as well as on the metabolic responses to the treatment.

Insertional Mutagenesis of the Flavinogenic Yeast Candida famata (Candida flareri)

2014
Genetic transformation is a primary prerequisite for efficient gene manipulation of a target microorganism. Here, we describe the method of electrotransformation (electroporation) of the flavinogenic yeast Candida famata (Candida flareri), available selective markers for the selection of the transformants and insertional mutagenesis for this yeast ...

Flocculation of the Yeast Candida famata (Debaryomyces hansenii): An Essential Role for Peptone

Yeast, 1996
Aggregation of Candida famata (Debaryomyces hansenii) is consistent with being a form of lectin-mediated yeast flocculation. Flocculation of C. famata is unusual in that it requires the presence of peptone, either in the growth medium or added later to harvested cells in buffer.

Development of a transformation system for the flavinogenic yeastCandida famata

FEMS Yeast Research, 2002
Riboflavin-overproducing mutants of the flavinogenic yeast Candida famata are used for industrial riboflavin production. This paper describes the development of an efficient transformation system for this species. Leucine-deficient mutants have been isolated from C. famata VKM Y-9 wild-type strain.

Unusual flocculation characteristics of the yeast Candida famata (Debaryomyces hansenii)

Letters in Applied Microbiology, 1993
Candida famata NCYC 576 cells aggregated throughout growth in YEPD. Aggregates were dispersed by Pronase E, EDTA or specific sugars. EDTA-dispersed cells reaggregated after calcium ion addition. Unlike Saccharomyces cerevisiae, C. famata cells lost the ability to flocculate with repeated EDTA washings. These cells regained flocculation when resuspended

Induced Biofilm Cultivation Enhances Riboflavin Production by an Intertidally Derived Candida famata

Applied Biochemistry and Biotechnology, 2012
The aim of the investigation was to ascertain if surface attachment of Candida famata and aeration enhanced riboflavin production. A newly designed polymethylmethacrylate (PMMA) conico-cylindrical flask (CCF) holding eight equidistantly spaced rectangular strips mounted radially on a circular disk allowed comparison of riboflavin production between ...

Effect of Gene SFU1 on Riboflavin Synthesis in Flavinogenic Yeast Candida famata

Cytology and Genetics, 2020
Abstract—Riboflavin or vitamin B2 is a necessary component for all living organisms since it is the precursor of flavin coenzymes FMN (flavin mononucleotide) and FAD (flavin adenine dinucleotide), which are involved in numerous enzymatic reactions. Flavinogenic yeast Candida famata overproduces riboflavin under iron starvation; however, regulation of ...
