Large amount of glycerol production from biodiesel industries as byproduct has substantially decreased its cost. This attracted many fermentation industries to use glycerol as carbon source. The production of industrially important chemicals such as 1,3-propanediol (1,3-PDO), 3-hydroxypropionic acid (3-HP) etc. from glycerol will be an value added contribution to biodiesel industries. Citrobacter amalonaticus Y19, a chemoheterotrophic enterobacter well documented for its ability to convert carbon monoxide to biohydrogen was studied for its capability to assimilate glycerol as the sole carbon source [1]. C. amalonaticus Y19 when cultivated under controlled conditions in presence of glycerol produced significant amount of various industrially important metabolites such as 1,3-PDO, 3-hydroxypropanealdehyde, 3-HP, pyruvate and ethanol by consuming glycerol at high rate. The contig sequencing and genome annotation revealed the presence of glycerol assimilating genes similar to E. coli along with coenzyme B12 synthesizing and 1,2- propanediol degrading genes. Vitamin B12 synthesis and faster glycerol consumption rate made C. amalonaticus Y19 a more promising strain for 1,3-PDO production.
