The two distinct domains of flavocytochrome b2 (L-lactate:cytochrome c oxidoreductase) are connected by a typical hinge peptide. The amino acid sequence of this interdomain hinge is dramatically different in flavocytochromes b2 from Saccharomyces cerevisiae and Hansenula anomala. This difference in the hinge is believed to contribute to the difference in kinetic properties between the two enzym...

Results: Overall agreement rates within ±1 dilution between the 2 methods were 86.7% (24 h) and 94.1% (48 h) for amphotericin B, and 85.5% (24 h) and 73.3% (48 h) for fluconazole. All C. albicans, C. pelliculosa, C. glabrata, and C. kefyr isolates were inhibited by ≤1 μg mL−1 of amphotericin B, and fluconazole resistance was not observed in C. albicans or C. tropicalis isolates according to the...

Abstract Aim of this study is to analyse the microbiological composition grapes and soil from a home vineyard located in Rzeszów. During research, following tasks were undertaken: determination total number microorganisms, isolation microbial cultures soil, identification bacterial strains yeast using MALDI-TOF MS Biotyper mass spectrometry. Natural microbiota are very diverse. Microbiological ...

Improvement of production of an extracellular β-glucosidase with high activity by Brettanomyces anomalus PSY-001 was performed by using recursive protoplast fusion in a genome-shuffling format. The initial population was generated by ultraviolet irradiation, ultrasonic mutagenesis and, then, subjected to recursive protoplast fusion. Mutant strains exhibiting significantly higher β-glucosidase a...

A yeast strain designated as Y-1 was isolated and characterized from wine yeast ("Jiuqu"). Based on the morphological and biochemical results, along with the rDNA internal transcribed spacer region (ITS), Y-1 was identified to be a Pichia anomala strain. Y-1 is an ethanol-tolerant strain, enduring ethanol concentrations of up to 14 %. Y-1 growth medium conditions were optimized, results showing...

Sidnie Manton became best known for her work on arthropod locomotion, and for proposing radical views on the evolution of arthropods that were accepted for a generation. However, her early training was as an embryologist, and the work that she carried out at the beginning of her career still stands as one of the major twentieth century contributions to the study of crustacean embryology. Here, ...
