Background: Borojoa sorbilis (Ducke) is an Amazonian species with edible fruits that are widely consumed by the local population, but little studied and not yet economically explored. Thus the aim of this study was to describe the chemical composition, volatile compounds, nutritional aspects and antioxidant activity of the fruit pulp and peel of B. sorbilis.

It is a cheap natural substrate because it is a by-product of the Eucalyptus cultivation for wood and pulp production. In this study, it was evaluated the potential of three filamentous fungi in the biotransformation of 1,8-cineole.

- The β-ketoester benzyl acetoacetate was successfully reduced to benzyl (S)-3-hydroxybutanoate using various microorganisms, with Hansenula sp. achieving the highest enantiomeric excess (ee) of 97% and 85% conversion in 24 hours.
- After immobilizing the yeast Kluyveromyces marxianus in calcium alginate spheres, it demonstrated improved stability, remaining effective through two reaction cycles.
- This study highlights the potential of specific yeasts in efficiently catalyzing enantioselective reductions in biochemical applications.
Many Trichoderma species are able to produce 6-pentyl-α-pyrone (6-PP), a lactone with coconut-like aroma. In the present work, several culture parameters were studied to enhance the production of 6-PP by Trichoderma harzianum 4040 in solid-state fermentation. Green coir powder added to a nutrient solution was used as support material for fermentation.
