Biotechnological production of 1,3-propanediol from crude glycerol
1,3-Propanediol (1,3-PD) is one of the important products used in chemical industry, in particular for polyesters production (e.g. polyethers and polyurethanes). Using crude glycerol for producing 1,3-PD is a good solution from the economical as well as ecological point of view. Glycerol produced by cleavage of natural fats can be microbially converted to 1.3-propanediol by, among others, Citro...
متن کاملVasconcelos Production of 1 , 3 - propanediol by Clostridium butyricum VPI 3266 using a synthetic medium and raw glycerol
Growth inhibition of Clostridium butyricum VPI 3266 by raw glycerol, obtained from the biodiesel production process, was evaluated. C. butyricum presents the same tolerance to raw and to commercial glycerol, when both are of similar grade, i.e. above 87% (w/v). A 39% increase of growth inhibition was observed in the presence of 100 g l 1 of a lower grade raw glycerol (65% w/v). Furthermore, 1,3...
متن کاملProduction of 1,3-Propanediol from Glycerol by Clostridium acetobutylicum and Other Clostridium Species.
Glycerol was fermented with the production of 1,3-propanediol as the major fermentation product by four strains of Clostridium acetobutylicum, six of C. butylicum, two of C. beijerinckii, one of C. kainantoi, and three of C. butyricum. 1,3-Propanediol was identified by its retention times in gas chromatography and high-pressure liquid chromatography and by its mass spectrum. During growth of C....
متن کامل1,3-propanediol production by Escherichia coli expressing genes of dha operon from Clostridium butyricum 2CR371.5.
1,3-propanediol is used as a monomer in the production of some polymers e.g. polytrimethylene terephthalate used in the production of carpets and textile fibers and in the thermoplastics engineering. However, the traditional chemical synthesis is expensive, generates some toxic intermediates and requires a reduction step under high hydrogen pressure. Biological production of 1,3-propanediol cou...
متن کاملMetabolic engineering of Clostridium acetobutylicum for the industrial production of 1,3-propanediol from glycerol.
Clostridium butyricum is to our knowledge the best natural 1,3-propanediol producer from glycerol and the only microorganism identified so far to use a coenzyme B12-independent glycerol dehydratase. However, to develop an economical process of 1,3-propanediol production, it would be necessary to improve the strain by a metabolic engineering approach. Unfortunately, no genetic tools are currentl...
