Crosstalk between Yeast Cell Plasma Membrane Ergosterol Content and Cell Wall Stiffness

Crosstalk between Yeast Cell Plasma Membrane Ergosterol Content and Cell Wall Stiffness | iBB | Scoop.it

A BSRG-iBB research paper just published in Journal of Fungi (special issue “Yeast Biorefineries”) provides a comprehensive view of the effect that the content of ergosterol at yeast plasma membrane, associated to membrane ABC transporter Pdr18 activity, influences cell wall biophysical properties under acetic acid-induced stress,  as part of a coordinated response to counteract the deleterious effects of this important stress factor in lignocellulosic biorefineries. This research work is first-authored by the PhD student of the PhD programme in Biotechnology and Biosciences Ricardo Ribeiro (FCT_DP AEM fellowship), performed under the supervision of Isabel Sá-Correia and is also co-authored by Cláudia P. Godinho, also from the BSRG-iBB team. This is a collaborative study with Fábio Fernandes (BSIRG-iBB) and Mário S. Rodrigues and his team (BioISI, Faculty of Sciences, ULisboa).

Ricardo Ribeiro Delivers Oral Presentation at the 7th Conference on Physiology of Yeast and Filamentous Fungi | iBB | Scoop.it

Ricardo Ribeiro, PhD student from the PhD program AEM - Applied

Environmental Microbiology delivered an oral presentation at the 7th Conference on Physiology of Yeast and Filamentous Fungi titled “Yeast response and tolerance to acetic acid: focus on the cell envelope” The work involves a collaboration between researchers from BSRG-iBB and BioISI. The meeting brought together researchers to exchange knowledge in the field of applied

physiology of yeasts and filamentous fungi, boosting the  understanding of these systems, envisaging their application in biotechnological, food, beverage and pharmaceutical industries. The conference took place in Milan, Italy, on the 24th-27th June.

Ricardo Ribeiro, IST PhD student in Biotechnology and Biosciences
from the FCT doctoral programme in Applied and Environmental
Microbiology (DP_AEM), at iBB-BSRG, presented his work during the symposium on “Molecular Microbiology and Microbial Physiology” of the Congress of Microbiology and Biotechnology 2019 (Microbiotec’19) which was held between the 5th and 7th of December 2019 in Coimbra, Portugal. The presentation was entitled “Yeast response and tolerance to acetic acid: focus on the cell envelope” This work was carried out under supervision of Prof. Dr. Isabel Sá- Correia (iBB-BSRG) and the collaboration of Dr. Mário Rodrigues’s team (BioISI), for the atomic force microscopy characterization of cell wall properties.
