In the current study, two molds, Aspergillus flavus (ACC# LC325160) and Penicillium chrysogenum (ACC# LC325162) were inoculated into two types of wood to be examined using scanning electron microscopy-energy dispersive X-ray (SEM-EDX) and computerized tomography (CT) scanning. Ficus sycomorus, a non-durable wood, and Tectona grandis, a durable wood, were the two wood blocks chosen, and they were inoculated with the two molds and incubated for 36 months at an ambient temperature of 27 ± 2 °C and 70 ± 5% relative humidity (RH). The surface and a 5-mm depth of inoculated wood blocks were histologically evaluated using SEM and CT images. The results showed that A. flavus and P. chrysogenum grew enormously on and inside of F. sycomorus wood blocks, but T. grandis wood displayed resistance to mold growth. The atomic percentages of C declined from 61.69% (control) to 59.33% in F. sycomorus wood samples inoculated with A. flavus while O increased from 37.81 to 39.59%. P. chrysogenum caused the C and O atomic percentages in F. sycomorus wood to drop to 58.43%, and 26.34%, respectively. C with atomic percentages in Teak wood's C content fell from 70.85 to 54.16%, and 40.89%, after being inoculated with A. flavus and P. chrysogenum. The O atomic percentage rose from 28.78 to 45.19% and 52.43%, when inoculated with A. flavus and P. chrysogenum, respectively. Depending on how durable each wood was, The examined fungi were able to attack the two distinct types of wood in various deterioration patterns. T. grandis wood overtaken by the two molds under study appears to be a useful material for a variety of uses.
