Abstract

Fed-batch fermentation conditions of Brevndimonas diminut JNPP-NSS for L-proline production were studied.The results showed that the synthetic concentration of the L-proline was improved under the conditions as follows: the initial precursor glutamic acid concentration was 50 g/L,the optimal original glucose concentration was 100 g/L,the glucose was fed with 3.0 g/(L·h) at 35 h,and the total glucose concentration was 120 g/L.As a result,the concentration of L-proline increased to 54.40 g/L with a yield of 0.45 g/g.

Key words： L-proline; Brevndimonas diminut; precursor; carbon source; fed-batch fermentation
