Biofoams with untapped enzymatic potential produced from beer bagasse by indigenous fungal strains.

White rot fungi are promising organisms for the production of mycelial-based biofoams, providing a sustainable means of valorizing lignocellulosic wastes. This study explores the utilization of two indigenous fungal species, isolated from Argentina and belonging to the genera Trametes, for producing biofoams from brewery waste. The resulting biofoams exhibited an average density of 0.

Broadening the repertoire of microbial aldo-keto reductases: cloning and characterization of AKR3B4 from Rhodotorula mucilaginosa LSL strain.

Aldo-keto reductases (AKRs) are nicotinamide-dependent enzymes that catalyze the transformation of aldehydes and ketones into alcohols. They are spread across all phyla, and those from microbial origin have proved to be highly robust and versatile biocatalysts. In this work, we have discovered and characterized a microbial AKR from the yeast Rhodotorula mucilaginosa by combining genome-mining and expression assays.
