Abstract

The comparative study of microorganisms associated with the spoilage of banana. “Banana is a general term embracing a number of species or hybrid in the genus musa, family bacteria organisms, small pieces of decayed tissue from the leading edge of the lesion was transferred, by means of sterile techniques, to the SDA contained in covered dishes and incubated at room temperature (28-370c). The fungal and bacterial growth visible within 2-7 days. Each observed fungal and bacterial growth based on their morphological and cultural microscopic examination and this microscopic examination was done using the lactophenol staining technique. Some organisms like Erwinia species has been incriminated as pathogen, saprophyte or constituent of epiphyic flora of plants.

INTRODUCTION
rn
rn Banana may be defined as a personal seed plant that produces an edible fruits, usually seedless, belong to the species M. acuminata, or are hybrids M. acuminata, M. balbisnna. They are perennial herbs with long, the bases of these leaves (petioles) remain tightyly fused and form the trunk (Pseudostem) of a plant 2-9m (6-30-ft) in height (Ploetz, 1994),
rn
rn “Banana” is a general term embracing a number of species or hybrids in the genus musa, family musceae. In some areas of the world bananas are grown only as ornamental plants or for fiber.
rn
rn It is found in tropical regions. The banana is monocarpic, flowering and setting fruit once before sit dies. The inflorescence protective flag leaf. The flower stalk of most banana varieties is positively geotropic and bends from the vertical until its stop points towards vertical flower stalks are from 30 – 90 cm (1-3ft) along, tapered and covered in a sheath of over- lapparing bracks the flower are parthenogenic (self-fertile). And occur in group of 12-20 beneath the bracks.
rn
rn At first, individual fruiots called fingers, make up the groups (hands) which are arranged in a spiral around the flower stalk, forming a bunch.
rn
rn At fruit set, a healthy banana plant will have 8-12 leaves, fruits mature in 60-100 days after flowers first appears depending on the season and cultivan. New banana plants arise as suckers from an underground rhizone. As old planted die and new sucher are formed the rhizome expands and is called a mat. Banana are propagated by suckens, pieces of the Bluzome and by tissue culture (Ploetz 1994)
