Preservation of Rhizopus in Bentonite Clay as Bio-starter

Effective and efficient preservation process is necessary in terms of increasing the fungal usage for industrial scale as biostarter. The objective of this study was to identify bentonite characteristic to be carrier to preserve of Rhizopus spore and to determine its viability after preservation process. The clay of bentonite characteristics were identified by BET (Brunaeur Emmett Teller) and SEM-EDS (Scanning Electron Microscopy-Energy Dispersive Spectroscopy) for determining surface properties and elements within the minerals, XRD (X-Ray Diffraction) for identifying the mineral, and AAS (Atomic Absorption Spectroscopy) for determining chemical composition. The growth of microbial preserved in bentonite tablet after stored for 20, 40, and 60 days was identified by TPC (Total Plate Count). Bentonite has a main component as silica-SiO
