Summary: This review examines the current knowledge and potential of yeasts in bromeliads, highlighting the existing knowledge gaps. While some yeast species with biotechnological potential have been isolated, there is still much to be explored in understanding the diversity of yeasts in bromeliads. Furthermore, bromeliads serve as a valuable model for studying the interaction between plants and yeasts, with the yeast community varying among different plant compartments.

Summary: The yeast strain Cy. xylosilytica UFMG-CM-Y309 has been found to reduce acetic acid concentration in sugarcane bagasse hemicellulosic hydrolysate while producing xylitol. The research evaluated the influence of volumetric oxygen transfer coefficient (k(L)a) on xylitol production and acetic acid consumption. It was found that a lower k(L)a value (21 h(-1)) resulted in higher xylitol production and slower acetic acid consumption, while a higher k(L)a value (35 h(-1)) led to faster acetic acid consumption but lower xylitol production.

Summary: Riparian forests provide plant litter for terrestrial and aquatic ecosystems, and this study explored the traits of litter from riparian forests in three South American biomes. The findings showed similarities and differences in litter traits, with litter from drier biomes being more chemically defended and lower in nutritional quality than litter from humid biomes. The study also found that trait differences across biomes were primarily determined by environmental factors rather than phylogenetics.

Summary: This study investigated the microbiota associated with the mucus and tissue of an endemic coral species, Siderastrea stellata, in Brazilian northeast coral reefs. The results showed that the microbial community structure was influenced by seasonality and the health status of the coral. Additionally, the impact of river runoff on the coral microbiota was not as significant as expected.

Summary: Two novel species of the genus Sugiyamaella were discovered in passalid beetles and their habitats in the Amazonian Forest in Brazil. These species, Sugiyamaella amazoniana and Sugiyamaella bielyi, are phylogenetically related to other Sugiyamaella species but exhibit distinct differences. They appear to have a close association with passalid beetles and their ecological niches in the Amazonian biome.

Summary: Tropical rainforests and related biomes are tremendous sources of novel yeasts. Tropical yeasts participate in several ecological interactions that contribute to the health of these ecosystems. Most studies of yeast diversity in tropical forests were carried out using culture-dependent methods. Yeasts from tropical rainforests are rich sources for bioinnovation.

Summary: By studying the genetic characteristics of different industrial yeast strains used in Brazil for fuel ethanol and cachaca production, it was found that invertase activity may not limit sucrose fermentation. A modified industrial yeast strain with altered sucrose metabolism was able to consume the disaccharide directly and achieve higher ethanol production.
