G Prasada Babu, D Chakravarthy, K Jaya Kumar and Chinthala Paramageetham

Pseudomonas cichoriiisolates were obtained from forest soils in Seshachalm hills using selective medium. The isolates were screened for phosphate activity and all the isolates were gram negative and showed bright fluorescence under UV light. The cultural and biochemical characteristics confirmed that the isolates were P.cichorii. Carbohydrates utilization profiles confirmed that the isolates were able to utilize Lactose, Xylose, Fructose, Glycerol, Trehalose, Mannitol and Ribose. However, the isolates were unable to utilize glucose and sucrose. The isolates showed positive results for levan production, oxidase and HCN. However they were negative for citrate utilization, ONPG and Gelatin hydrolysis.
