Abstract

Daripada 9 pencilan kulat yang disaring, didapati pencilan USM F4 mampu menghasilkan aktiviti mannanase yang lebih tinggi berbanding dengan 8 pencilan lain. Pengecaman melalui morfologi dan mikroskopik menunjukkan kulat tersebut mempunyai ciri-ciri Aspergillus niger. Penghasilan mannanase oleh A. niger USM F4 dioptimumkan berdasarkan keadaan pengkulturan dan medium pemfermentasian dalam dua sistem utama; sistem kelalang goncangan dan dulang. From the 9 isolates of fungi that were screened, the isolate USM F4 was found capable to produce higher mannanase activity than the other 8 of fungal isolates. The colony and microscopic morphologies identification showed that this fungal was very identical to Aspergillus niger. The production of mannanase by A. niger USM F4 was futher optimised based on the cultural conditions and fermentation medium in two main systems; flask and tray systems.
