| Research Abstract |
A very safe and environmentally friendly solid-state material for bioremediation was prepared using a combination of Aspergillus oryzae, a porous biodegradable polymer. The novel material was capable of decomposing 200 ppm formaldehyde solution to 0 ppm within 7 days. Degradation ability was prolonged by addition of yeast extract-peptone- dextrose (YPD) medium into the composite; 200 ppm formaldehyde was decomposed to 0 ppm over 8 additional decomposition cycles and 100 days. A unique mechanism is proposed where, during degradation, the solid-state composite provides nutrients to A. oryzae.
