Biochemical and biological evaluation of L-glutaminase from Aspergillus tamarii AUMC 10198 via solid-state fermentation.

Introduction: Fungal L-glutaminase has recently attracted growing interest due to its potential applications in medical therapy and biotechnology. This study aimed to develop a cost-effective bioprocess for L-glutaminase production using agricultural by-products under solid-state fermentation (SSF). Several fungal isolates were screened for extracellular L-glutaminase production, and the native isolated strain Aspergillus tamarii AUMC 10198 was identified as a potent high-yield producer.
