Propitious catalytic response of immobilized α-amylase from G. thermoleovorans in modified APTES-FeO NPs for industrial bio-processing.

Challenges in enzyme and product recovery are currently intriguing in modern biotechnology. Coping enzyme stability, shelf life and efficiency, nanomaterials-based immobilization were epitomized of industrial practice. Herein, a α-amylase from Geobacillus thermoleovorans was purified and bound effectively on to a modified 3-Aminopropyltriethoxysilane (APTES)-FeO nanoparticle.

Thermostable lipase from Geobacillus sp. Iso5: bioseparation, characterization and native structural studies.

The extracellular thermoalkaline lipase from Geobacillus sp. Iso5 was purified to homogeneity by ultrafiltration, 6% cross-linked agarose and Phenyl spehrose HIC column chromatography. The final purified lipase resulted in 8.
