Bacterial cellulose is a strong, highly pure form of cellulose that is used in a range of applications in industry, consumer goods and medicine. Gluconacetobacter hansenii ATCC 53582 is one of the highest reported bacterial cellulose producing strains and has been used as a model organism in numerous studies of bacterial cellulose production and studies aiming to increased cellulose productivit...

A 65-yr-old female developed cough, fever and dyspnoea following repeated exposure to a home ultrasonic humidifier. High-resolution computed tomography showed ground-glass opacity in both lung fields. Arterial blood gas analysis gave an oxygen tension of 8.38 kPa (63 Torr). Pulmonary function testing revealed restrictive ventilatory impairment with a reduction in the diffusing capacity. The dia...

Waste cobs from variously processed (premature, uncooked, roasted, cooked salted, cooked unsalted) maize (Zea mays) were used as raw materials to prepare growth agar media for six moulds: Rhizopus nigricans, Aspergillus niger, Trichoderma viride, Alternaria tenuis, Fusarium sp, Penicillium sp. and one yeast: Debaryomyces sp. All the formulated media supported the growth of the microorganisms te...

Two genes encoding Na(+)-ATPases from Debaryomyces hansenii were cloned and sequenced. The genes, designated ENA1 from D. hansenii (DhENA1) and DhENA2, exhibited high homology with the corresponding genes from Schwanniomyces occidentalis. DhENA1 was expressed in the presence of high Na(+) concentrations, while the expression of DhENA2 also required high pH. A mutant of Saccharomyces cerevisiae ...

The inhibitory effects of three topical anesthetics of various concentrations on the growth of Pullularia pullulans, Debaryomyces hansenii, and on pigment production by P. pullulans were investigated. The topical anesthetics were benoxinate hydrochloride, proparacaine hydrochloride, and tetracaine hydrochloride. In decreasing order, the inhibiting effects of the drugs on growth were benoxinate,...

The two biotechnologically important Ascomycetes, Pichia membranifaciens and Debaryomyces hansenii, were tested (in active and inactive form), in the present study for efficient bioreduction of trivalent aurum to gold nanoparticles. Strong surface plasmon resonance was observed, between 530 and 540 nm, from the gold nanoparticles recovered from the test Ascomycetes. The characterization of the ...

Debaryomyces hansenii is a halotolerant yeast that produces and assimilates a wide variety of polyols. In this work we evaluate polyol transport in D. hansenii CBS 767, detecting the occurrence of polyol/H(+) (and sugar/H(+)) symporter activity, through the transient extracellular alkalinization of unbuffered starved cell suspensions. From the D. hansenii genome database, we selected nine ORFs ...

Background: Psoriasis is an immune mediated skin disorderwhich is mainly characterized by abnormal proliferation anddifferentiation of keratinocytes. It is believed that Debaryomyceshansenii (Candida famata) can colonize skin and mucous membranesof psoriatic patients and exacerbate psoriatic lesions via toxins,antigens, and proteins. The aims of this study were to evaluateDebaryomyces hansenii ...

Desalter effluent (DE) is typically discharged into a petroleum wastewater treatment plant, but its high salt concentration deteriorates the biological treatment. This study used various dilution rates to investigate of synthetic DE containing dodecane under saline conditions using halotolerant yeast, Debaryomyces hansenii, determine optimum substrate for use in continuous stirred-tank reactors...

The Gram-negative bacterium Gluconacetobacter hansenii is considered a model organism for studying cellulose synthesis. We have determined the genome sequence of strain ATCC 23769.
