ABSTRACT
Six strains of  microorganisms were screened  for  Exopolysaccharide  production.  Alternaria alternata was recognized to produce high levels of the EPS. The effects of environmental parameters on polysaccharide production by Alternaria alternate were investigated.  Results showed the optimum temperature and initial pH for exopolysaccharide (EPS) production in shake flask cultures of Alternaria alternate were found to be 30℃and pH 3.0, respectively. Incubation period required for maximum production was 9days. glucose was found to be the best carbon source to production of EPS, various concentrations of glucose were applied for the screening of the suitability of EPS production. 4% glucose was favorable to production of EPS. Yeast extract gave the highest amount of EPS by Alternaria alternate, its maximum concentration for EPS was determined.
Keywords: Alternaria alternate, EPS production, physiological conditions
