Unravelling the Molecular Responses of the Yeast Schwanniomyces etchellsii to Hyperosmotic Stress in Seawater Medium Using Omic Approaches

Cecilia Andreu, Èlia Obis, Marcel·lí del Olmo

is an unconventional, halotolerant microorganism. Like some other yeasts, it can efficiently perform various biocatalytic transformations of organic compounds in seawater more effectively than in freshwater. In seawater, conversion rates are higher, by-product production is minimized, greater substrate loading is possible, and …

Current Status of the Application of Antimicrobial Peptides and Their Conjugated Derivatives

Marcel·lí del Olmo, Cecilia Andreu

A significant issue in healthcare is the growing prevalence of antibiotic-resistant strains. Therefore, it is necessary to develop strategies for discovering new antibacterial compounds, either by identifying natural products or by designing semisynthetic or synthetic compounds with this property. In this context, …

Strategies Used for the Discovery of New Microbial Metabolites with Antibiotic Activity

Pablo Dasí-Delgado, Cecilia Andreu, Marcel·lí del Olmo

The discovery of new microbial metabolites is essential to combat the alarming rise in antimicrobial resistance and to meet emerging medical needs. This work critically reviews current strategies for identifying antimicrobial compounds, emphasizing the potential of microorganisms as a rich source of …

Biocatalysis with Unconventional Yeasts

Cecilia Andreu, Marcel·lí del Olmo

Biocatalysis is a green and sustainable technology based on the use of natural substances to catalyze chemical reactions. Humans have been unconsciously using biocatalysis for thousands of years to produce food and alcoholic beverages, but it is only since the 19th century …

Proteomics characterization of biofilm formation by salt-tolerant Schwannyomyces etchellsii in seawater-based growth medium

Cecilia Andreu, Marcel·lí del Olmo

Microbial biofilms are complex communities with cells embedded in an extracellular matrix. We previously discovered that salt-tolerant yeasts Debaryomyces fabryi, Schwanniomyces etchellsii, Schwanniomyces polymorphus and Kluyveromyces marxianus were able to form biofilms when grown in seawater- but not in freshwater-based media. The …

Antimicrobial Properties of New Polyamines Conjugated with Oxygen-Containing Aromatic Functional Groups

Mario Inclán, Neus Torres Hernández, Alejandro Martínez Serra, Gonzalo Torrijos Jabón et autres

Antibiotic resistance is now a first-order health problem, which makes the development of new families of antimicrobials imperative. These compounds should ideally be inexpensive, readily available, highly active, and non-toxic. Here, we present the results of our investigation regarding the antimicrobial activity …
