Bacteriological Analysis of Deteriorated Persea Americana (Pear Fruit)

The Avocado pear (Perseaamericana) is a member of the family Lauraceae. This fruit has a short shelf-life, it can be averagely stored 3-6days before spoilage. This study was aimed at analysing bacteriologically deteriorated Avocado pear (Perseaamericana). The sample was collected and allowed to spoil before serial dilution was conducted. There was growth of five (5) bacteria organism that was identified. Bacillus species had very high growth (5.1 x 105 cfu/g) followed by shigellaspecies, staphylococcus aureus which were moderate and salmonella sp. which was few. Biochemical analysis was carried out, which include gram staining, catalase test and Indole test. This research work should be encouraged for more parasitic organisms such as fungi and virus contamination. This project work was achieved.
