Increase in the incidence of Insulin Dependent Diabetes Mellitus (IDDM) among people from developed and developing countries has created a large global market for insulin. Moreover, exploration of new methods for insulin delivery including oral or inhalation route which require very high doses would further increase the demand of cost-effective recombinant insulin. Various bacterial and yeast s...

Dietary restriction is generally assumed to increase the lifespan in most eukaryotes, including the simple model organism Saccharomyces cerevisiae. However, recent data questioned whether this phenomenon is indeed true for yeast. We studied the effect of reduction of the carbon source concentration on the chronological lifespan of the yeast Hansenula polymorpha using four different carbon sourc...

Pichia kudriavzevii NG7 is a multistress-tolerant yeast, isolated from grape skins. Here, we report the draft genome sequence of P. kudriavzevii NG7, to understand its biochemical regulation and metabolic pathways.

BACKGROUND Non-conventional yeasts present a huge, yet barely exploited, resource of yeast biodiversity for industrial applications. This presents a great opportunity to explore alternative ethanol-fermenting yeasts that are more adapted to some of the stress factors present in the harsh environmental conditions in second-generation (2G) bioethanol fermentation. Extremely tolerant yeast species...

The present work is initiated to investigate whether a defined culture comprising a mixture of three yeast species, Kluyveromyces marxianus, Saccharomyces cerevisiae, and Pichia stipitis can ferment a mixture of sugars to produce bioethanol at rates higher than those achieved by pure cultures of the same. For this purpose, we develop models of single species based on the hybrid cybernetic model...

to accomplish the worldwide demand for recombinant human erythropoietin (rhuepo) as a therapeutic, application of cost-efficient expression system of methylotrophic yeast pichia pastoris (p. pastoris) rather than mammalian cells is indispensable. herein, a report on high levels secreted-expression of pichia-derived rhuepo by batch fermentation in a ph stabilized format is presented. the full le...

phytic acid is the dominant form of phosphorous in plant seeds. however, phytic acid cannot beutilized by animals and causes them serious phosphate deficiency. utilization of phytase as ananimal feed additive can affect liberation of phosphor and its mineral availability. in this study,heterologous expression of the a. niger phya gene was investigated in the methylotrophic yeastsp. pastoris and...
