Summary
Researchers screened 89 yeast cultures for alpha-galactosidase biosynthesis. The yeast Schwanniomyces alluvius 1167 demonstrated the highest activity, which was enhanced 4.8-fold through optimized cultivation.
Area of Science:
- Microbiology
- Enzymology
- Industrial Biotechnology
Context:
- Investigating microbial enzyme production is crucial for industrial applications.
- Dry whey is a common byproduct with potential for bioprocessing.
- Screening diverse yeast genera is essential for identifying novel enzyme producers.
Purpose:
- To identify yeast strains capable of synthesizing alpha-galactosidase.
- To optimize cultivation conditions for enhanced enzyme activity.
- To evaluate the potential of Schwanniomyces species in industrial enzyme production.
Summary:
- A study examined alpha-galactosidase biosynthesis in 89 yeast cultures across 21 genera using submerged cultivation with dry whey.
- The enzyme production capacity was exclusively identified within the Schwanniomyces genus.
- The strain Schwanniomyces alluvius 1167 exhibited the highest alpha-galactosidase activity, which was subsequently increased 4.8-fold by optimizing cultivation conditions.
Impact:
- Identifies Schwanniomyces as a key genus for alpha-galactosidase production.
- Demonstrates a significant increase in enzyme activity through process optimization.
- Highlights potential for utilizing dry whey in yeast fermentation for enzyme biosynthesis.
