| Abstract: | Screening of Rhamnolipid-producing Pseudomonas Mutants was carried out by rhamnolipid .The fermentation conditions in shaking flask were investigated.The optimal medium and the fermentation technology were demonstrated.After mutation of rhamnolcpid,a high-yielding strain of rhamnolipcd,namely strain 322,was obtailced,whose yield was 27.5g/L,which was 57.14% higher than that by the original strain. |
