Recovery of 6-pentyl-alpha-pyrone fromTrichoderma viride culture medium by perevaporation

  • Published:
Biotechnology Techniques

Summary

Cultivation ofTrichoderma viride yields the volatile lactone 6-pentyl-alpha-pyrone (6-PP) as principal metabolite in concentration of up to 1 g/l. Separation and enrichment of 6-PP from the culture medium is effected by pervaporation through hydrophobic membranes. Virtually complete removal of 6-PP from inactive culture medium is achieved by batch pervaporation. Unlike steam distillation, pervaporation may be directly coupled to the active fermenter.
