ABSTRACT

The contributions of microorganisms in deterioration of African breadfruit during storage was investigated in this study. Matured breadfruit of seeded variety of African breadfruit (Artocarpus altilis) was stored under room temperature and morphological changes observed at 24hrs interval. Spoilage of breadfruit was observed after 72hrs with microbial growth. The study thus revealed that microorganisms play a substantial role in the spoilage of African breadfruit. Strains of Aspergillus spp., Penicillium spp., Molinia spp., Yeast, Rhizopus spp.  and Fusarium spp. were isolated as fungal spoilage organisms. Bacillus spp., Pseudomonas spp., Staphylococcus spp., Streptococcus spp., Escherichia coli and Proteus spp. were isolated as bacteria spoilage organisms.
