The results showed that rotting wood collected from the Atlantic Rainforest is a valuable source of yeasts able to grow in sugarcane bagasse hydrolysate, including species with promising biotechnological properties.In nature, microorganisms often exhibit competitive behavior for nutrients and limited space, allowing them to alter the virulence determinants of pathogens. The human pathogenic yeast Cryptococcus neoformans can be found organized in biofilms, a complex community composed of an extracellular matrix which confers protection against predation. The aim of this study was to evaluate and characterize antagonistic interactions between two cohabiting microorganisms C. neoformans and the bacteria Serratia marcescens. The interaction of S. marcescens with C. neoformans expressed a negative effect on biofilm formation, polysaccharide capsule, production of urease, and melanization of the yeast. These findings evidence that competition in mixed communities can result in dominance by one species, with direct impact on the physiological modulation of virulence determinants. Such an approach is key for understating the response of communities to the presence of competitors and, ultimately, rationally designing communities to prevent and treat certain diseases.Mucor circinelloides is an opportunistic dimorphic pathogen, with the dimorphic process controlled in parts by fermentative and oxidative metabolisms, which lead to yeast or mycelial growth, respectively. Dimorphic transition is important for pathogenesis since the mycelium represents the virulent morphology. We previously reported that the deletion of arl1 or arl2 stimulate anaerobic germination in M. circinelloides, suggesting an augmented fermentative metabolism. In the present study, we demonstrate that the heterokaryon Δarl1(+)(-) and homokaryon Δarl2 strains contain low number of mitochon
