Abstract

1,3-Propanediol production by Klebsiella pneumoniae was studied in batch cultures under N2 flow and four airflow systems. Different byproducts were formed under different aeration conditions. An anaerobic/aerobic combined fed-batch culture was developed giving 70 g 1,3-propanediol l−1 and 16 g 2,3-butanediol l−1 with total diol yield of 0.6 mol−1 glycerol.
