Background: Ashbya gossypii is a filamentous fungus widely utilized for industrial riboflavin production and has a great potential as a microbial chassis for synthesizing other valuable metabolites such as folates, biolipids, and limonene. Engineered strains of A. gossypii can effectively use various waste streams, including xylose-rich feedstocks.

Background: Limonene is a cyclic monoterpene that has applications in the food, cosmetic, and pharmaceutical industries. The industrial production of limonene and its derivatives through plant extraction presents important drawbacks such as seasonal and climate issues, feedstock limitations, low efficiency and environmental concerns. Consequently, the implementation of efficient and eco-friendly bioprocesses for the production of limonene and other terpenes constitutes an attractive goal for microbial biotechnology.

Article Synopsis
  • The text discusses a filamentous fungus that is used industrially for riboflavin production and has engineered strains capable of synthesizing metabolites like folic acid and nucleosides.
  • It highlights the importance of effective gene expression systems for both native and foreign genes, emphasizing the need for novel promoters to enhance bioproduction capabilities.
  • The study introduces a modified Dual Luciferase Reporter Assay that identified 10 new promoters, including three strong and seven medium/weak ones, improving gene expression and influencing sporulation in mutant strains.

The co-utilization of mixed (pentose/hexose) sugars constitutes a challenge for microbial fermentations. The fungus Ashbya gossypii, which is currently exploited for the industrial production of riboflavin, has been presented as an efficient biocatalyst for the production of biolipids using xylose-rich substrates. However, the utilization of xylose in A.
