IMMOBILIZED ASPERGILLUS-SYDOWII PRODUCES XYLANASE

Spores of Aspergillus sydowii, immobilized in 2.5% calcium alginate was used as inoculum in batch cultures for production of xylanase enzyme using xylan as the sole carbon source. Partially germinated mycelium from these entrapped spores produced significant amount of the enzyme in a short period of 24 hours and the same inoculum could be used repeatedly for at least 5 cycles with less than 10% loss of enzyme activity.
