Microbes have evolved ways of interference competition to gain advantage over their ecological competitors. The use of secreted antagonistic compounds by yeast cells is one of the prominent examples. Although this killer behavior has been thoroughly studied in laboratory yeast strains, our knowledge of the antagonistic specificity of killer effects in nature remains limited. In this study, yeas...

We describe a case of bloodstream infection caused by a Candida krusei strain that developed echinocandin resistance during caspofungin therapy. Three mutations were found in the HS1 region of the fks1 gene, two of them have never been reported either in C. krusei nor in C. albicans.

A truncated form of surface antigen 2 (SAG2) of the protozoan parasite Toxoplasma gondii was cloned and expressed in the methylotrophic yeast Pichia pastoris. This recombinant antigen, designated as recSAG2-N, contained only the N-terminal half of the native SAG2. The recSAG2-N was secreted by the Pichia pastoris into the culture supernatant, and it was harvested by using the trichloroacetic ac...

cheese 13 RUNNING TITLE: Candida cabralensis sp. nov. from Cabrales cheese 14 15 Abstract 24 Three yeast strains, 1AD8, 3AD15 and 3AD23, belonging to a previously unknown 25 yeast species were isolated from two independent batches of the Spanish blue-veined 26 Cabrales cheese, a traditional cheese manufactured without the addition of starter and 27 mould cultures. Physiological characterisation...

An efficient method for Pichia cell disruption that employs an aminopropyl magnesium phyllosilicate (AMP) clay-assisted glass beads mill is presented. AMP clay is functionalized nanocomposite resembling the talc parent structure Si8Mg6O20(OH)4 that has been proven to permeate the bacterial membrane and cause cell lysis. The recombinant capsid protein of cowpea chlorotic mottle virus (CCMV) expr...

The discovery of six specimens of the enigmatic order Siphoniulida, including for the first time males, prompted a modern re-analysis of current phylogenetic schemes for the class Diplopoda derived from traditional morphological and developmental characters. The data matrix was constructed and analysed using paup. The resulting phylogenetic hypotheses corroborated the longest standing, traditio...

Microbial activity is an integral part of agricultural ecosystems and can influence the quality food commodities. During on-farm processing, coffee growers use a traditional method fermentation to remove cherry pulp surrounding beans. Here, we investigated farm microbiome resulting process conducted with selected starter cultures (Pichia fermentans YC5.2 Pediococcus acidilactici LPBC161). The m...

Marine fungi are important sources of new metabolites including certain enzymes medical interest due to their enormous capacity adapt themselves extreme environments. Living in a highly competitive ecological niche, they produce unusual chemical moieties. biological resources green, abundant, renewable and aid economic development. The present study investigates the production L-Glutaminase whi...

Recombinant protein production in Pichia pastoris is based on alcohol oxidase promoterswhich are regulated by methanol. However, the use of methanol has several disadvantages,which is why current trends in bioprocess development with Pichia pastoris (P. pastoris) arefocusing on methanol mixed feeding strategies. This work aimed to develop a new experimentalmethod and compare the effect of vario...

Background and Purpose: By using advanced detection/identification methods, the list of emerging uncommon opportunistic yeast infections is rapidly expanding worldwide. Our aim in the present study was sequence-based species delineation of previously unidentified yeasts obtained from a clinically yeast collection. Materials and Methods: A total of twenty three out of the 855 (5.7%) yeast isolat...
