The killer toxin from Pichia membranifaciens CYC 1106, a yeast isolated from fermenting olive brines, binds primarily to the (136)-b-D-glucan of the cell wall of a sensitive yeast (Candida boidinii IGC 3430). The (136)-b-D-glucan was purified from cell walls of C. boidinii by alkali and hot-acetic acid extraction, a procedure which solubilizes glucans. The major fraction of receptor activity re...

Nowadays, our knowledge of the fungal biodiversity in fermented vegetables is limited although these microorganisms could have a great influence on the quality and safety of this kind of food. This work uses a metagenetic approach to obtain basic knowledge of the fungal community ecology during the course of fermentation of natural Aloreña de Málaga table olives, from reception of raw material ...

BACKGROUND Absence or severe reduction in the amount of ergosterol in the fungal membrane and its replacement with other sterols have been described as potential antifungal resistance mechanisms in fungi. AIMS AND METHODS The ergosterol content in a collection of 51 clinical yeast isolates, including susceptible and resistant strains to amphotericin B and azoles, was estimated by a simple chr...

The killer toxin from Pichia membranifaciens CYC 1106, a yeast isolated from fermenting olive brines, binds primarily to the (1-->6)-beta-D-glucan of the cell wall of a sensitive yeast (Candida boidinii IGC 3430). The (1-->6)-beta-D-glucan was purified from cell walls of C. boidinii by alkali and hot-acetic acid extraction, a procedure which solubilizes glucans. The major fraction of receptor a...

the aim of this study was to evaluate the performances of methods such as sequencing of the internal transcribed spacer (its) and 26s (d1/d2) regions of ribosomal dna, rflp analysis of the its region and commercial biochemical test kit for the identification of the yeasts isolated during spontaneous fermentation of fresh crushed pineapple juice. the experiments were conducted in thailand and au...

Cultures of Penicillium expansum produce a musty, earthy odor. Geosmin [1,10-trans-dimethyl-trans(9)-decalol] was identified by gas chromatography-mass spectrometry from headspace samples of P. expansum cultures. Olfactory comparison of P. expansum cultures with a geosmin standard indicated geosmin is the primary component of the odor associated with P. expansum.

Pichia membranifaciens KS47-1 is capable of growing on hydrolysate containing high concentrations of acetate and other growth inhibitors. To reveal the acetate-resistant associate genes of strain KS47-1, we present the 11.4-Mb draft genome sequence.
