Abstract

Microorganisms are used in several industrial processes, such as the production of exopolysaccharides. The importance of exo-polysaccharides  is increasing especially microbial enzymes which are of indefinite industrial purposes. Liquid state fermentation is an economical alternative for the large scale production of enzymes which produced by microorganisms. Six fungal species and eight bacterial genera were screened for the ability to produce exo-polysccarides. Maximum production was recorded by B. amyloliquefacien. (98.44%) followed by Escherichia coli (35.88%) and Aspergillus flavus (30.11%). However, low values for exo-polysaccharides production were recorded by Trichoderma viridi (1.77%) and Cladosporium sp. (1.08 %). The results also showed that the production of exo-polysaccharides of each individual was always correlated with the density on the isolation plates and their frequencies. Based on the above results,  B. amyloliquefacien was selected as the highest producer of  exo-polysaccharides.
