Isolation and Identification of Molds Causing Spoilage of Bread Sold within Damaturu Metropolis, Yobe State, Nigeria.

Abstract

Bread was purchased from different shops in Damaturu. The bread was kept in different laboratory environment for three days after which fungal growth was observed. The bread was sub-cultured in Potato Dextrose Agar in 15 petri dishes and incubated for four days after which a growth was observed. Five (5) different organisms were isolated which include Aspergillus niger, Aspergillus. spp, and Rhizophus sp. The fungi isolated from this study when consumed can cause toxigenic infections in man. Proper and more sanitized methods of packaging, transportation and storage has been reported to reduce the problems of spoilage of breads, thus controlling and reducing the possibility of infections by these spoilage organisms.
