Orange
seed oil was extracted using the steam distillation method.
The fungi isolated from the leather samples were
Aspergillus niger, Aspergillus fumigatus,
Aspergillus flavus, Paecilomyces sp.,
Penicillium sp., Rhizopus nigricans and Alternaria
sp. However, the fungal species vary from person to
person. The orange seed oil was active against
Paecilomyces sp., Penicillium sp. and Rhizopus
nigricans at a minimum concentration of 2.0, 3.0 and
3.0%, respectively, whereas the other isolates were
inhibited at higher concentrations. There was considerable
reduction of the mycelia growth when 3% oil extract was
introduced into the medium as against growth on only
Czapek’s Agar medium. There was no inhibition against
Alternaria sp.
Key words: Sweet orange seed oil, Aspergillus
sp., Penicillium sp., extract. |
