Growth kinetic of rhizopus sp. immobilised on loofah sponge for whole-cell biocatalyst in different cultivation media / Azlin Suhaida Azmi … [et al.]

Immobilisation of filamentous fungi such as Rhizopus sp. onto biomass support particles (BSP) surface was studied as whole-cell biocatalyst. The function was to aid fermentation process. By using the microbial immobilisation process, the complex procedures of isolation, purification and immobilisati...
