Erythritol Production by a Yeastlike Fungus.

Host-parasite relationships in the yeastlike form of Paracoccidioides brasiliensis strain IVIC Pb9.

The yeastlike form of Paracoccidioides brasiliensis strain IVIC Pb9 reduced the amount of alpha-1,3-glucan in its cell wall from 45 to 3% when subcultured in vitro for several years. This strain regained its alpha-1,3-glucan up to 25% of the total cell wall when grown in vivo. A mutant strain of P. brasiliensis Pb9, named IVIC Pb140, reported to have 1,3-mannan instead of alpha-glucan in the ce...

Adaptation of the Cooper Recessed-top Polystyrene Tissue Culture Dish to Identification and Investigation of Candida and Other Yeastlike Fungi.

Molecular cloning and biochemical characterization of a novel erythrose reductase from Candida magnoliae JH110

BACKGROUND Erythrose reductase (ER) catalyzes the final step of erythritol production, which is reducing erythrose to erythritol using NAD(P)H as a cofactor. ER has gained interest because of its importance in the production of erythritol, which has extremely low digestibility and approved safety for diabetics. Although ERs were purified and characterized from microbial sources, the entire prim...

Paracoccidioides brasiliensis: conversion of yeastlike forms into mycelia in submerged culture.

Details of the sequential morphological changes occurring during yeastlike to mycelial-form conversion of the dimorphic pathogen Paracoccidioides brasiliensis are described and illustrated by photomicrographs. Conversion of yeastlike to hyphal morphology was initiated by changing the temperature of incubation from 37 to 23 C. Production by the parent yeastlike cells of elongated buds developing...

Reversible and permanent effects of the carbon sources and various antibiotics on the morphology and metabolic properties of Ustilago cynodontis cells

The effects of various carbon sources and of antibiotics on the morphology of hypha cells of the fungus Ustilago cynodontis is described. Nonfermentable substrates promote readily reversible yeastlike colonies from hypha cells: all the hypha cells spread on these substrates give rise to yeastlike colonies that revert to the mycelial phenotype when transferred to glucose medium. Among the antibi...
