BIOCONVERSION OF GLYCEROL

MANDAR KARVE, JAY J. PATEL, NIRMAL K. PATEL.

Abstract
The availability of petroleum sources in the near future is limited, so nowadays search for renewable energy sources are maximized. Biodiesel is one of the most important substituted for this problem. During biodiesel production, excessive glycerol is generated asbyproducts which contains impurities such as methanol, free fatty acid and salt. Thedisposal of glycerol leads to environmental problems. Alternatively glycerol can be utilized to obtain various valuable products viz.1,3-propanediol (1,3-PDO), 1,2-propanediol (1,2-PDO), ethanol, 2,3-butanediol, dihydroxyacetone, succinic acid, propionic acid and citric acid. Utilization of crude glycerol by means of chemical synthesis requires expensive catalysts like Ir, Cr, Ag etc. Comparatively biological method for utilizing crude glycerol is best to avoid environmental problems. Bioconversion of glycerol is carried out at 30- 400
C temperature and atmospheric pressure pressure which gives different products. Different microorganisms viz. Escherichia coli, Pseudomonas, Enterobacter aerogen, Klebsiella pneumoniae, Clostridium butaricum and Clostridium pasterium are reported to grow on glycerol to produce valuable chemicals. In this review article, bioconversion of glycerol to speciality chemicals such as ethanol, 1,3-PDO, 1,2-PDO, 2,3-butanediol, dihydroxyacetone, succinic acid, propionic acid and citric acid etc. Are discussed.

Key words: Bioconversion, Glycerol, Biodiesel, Microorganisms, 1,3-propanediol.
