LIPOLYTIC ACTIVITY OF BIOCATALYSTS OBTAINED AFTER IMMOBILISATION OF FUNGAL BIOMASS OF RHIZOPUS GENUS IN SIRAN

ABSTRACT



Siran was used as a ceramic carrier for the immobilisation of Rhizopus microsporus and Rhizopus nigricans fungi. Siran was cross-linked with glutaraldehyde or silanised to improve the capacity and stability of biomass immobilisation. The conditions of the obtained enzymatic preparations (immobilised and free) maintained in cooled (-20°C) acetone were determined.

Key words: immobilisation, Siran, Rhizopus microsporus, Rhizopus nigricans, activity of lipases, fat hydrolysis.
