Abstract

Microbial pectinolytic enzymes are known to play a commercially important role in a number of industrial processes. The objective of this study was to investigate the extracellular polygalacturonases of yeasts isolated from Brazilian semi-arid environments. Among the 250 colonies tested, only 33 produced extracellular polygalacturonases: Aureobasidium pullulans (18 isolates), Candida boidinii (one isolate), Trichosporonoides sp. (three isolates), Kluyveromyces marxianus (one isolate), Cryptococcus liquefaciens (one isolate), Pseudozyma sp. (four isolates), and yeast-like related to fungal endophyte (five isolates). The highest activity of polygalacturonase was observed in Pseudozyma sp. CCMB 300 (14.17±0.08 µmol acid galacturonic released/min/mg protein). This study shows the potential of yeasts and yeast-like organisms isolated from Brazilian semi-arid environments to produce pectinolytic enzymes.
