Screening of environmental samples for bacteria producing 1,3-propanediol from glycerol.
نویسندگان
چکیده
Twenty nine environmental samples were screened for the presence of anaerobic microorganisms fermenting glycerol with 1,3-propanediol as a final product. Seven samples were then selected for the next step of our research and eight bacteria strains were cultured anaerobically. Seven of them produced 1,3-propanediol with a yield of 0.47-0.58. Six of the the isolated microorganisms were then classified as Clostridium butyricum (four strains), C. lituseburense (one strain), and C. sartagoforme (one strain). We suggest that of all these strains C. butyricum 2CR371.5 is the best 1,3-propanediol producer as producing no lactate as a by-product and growing well on a glycerol-containing medium.

Isolation and partial characterization of a new strain of Klebsiella pneumoniae capable of high 1,3 propanediol production from glycerol
Glycerol is a promising feedstock for microbial cultivation and production of 1,3 propanediol (1,3 PDO). Here we report a newly isolated bacterial strain BA11 from soil, capable of fermenting glycerol to 1,3 PDO, and has been identified to be a strain of Klebsiella pneumoniae. Strain BA11 was fast growing showing peak 1,3 PDO production in 6 h of cultivation with productivity of 1.2 g/...
متن کاملGenome Sequence of Klebsiella pneumoniae HSL4, a New Strain Isolated from Mangrove Sediment for Biosynthesis of 1,3-Propanediol
Klebsiella pneumoniae HSL4 is a 1,3-propanediol-producing bacterium strain isolated from mangrove sediment. We present here a 5,221,448-bp assembly of its genome sequence. Genome analysis revealed that it contains 10 coding sequences (CDSs) responsible for glycerol fermentation to 1,3-propanediol, 19 CDSs encoding glycerol utilization, and 140 CDSs related to its virulence.
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 کاملGenome Sequence of Klebsiella pneumoniae Strain ATCC 25955, an Oxygen-Insensitive Producer of 1,3-Propanediol
Klebsiella pneumoniae strain ATCC 25955 is a 1,3-propanediol-producing bacterium that is insensitive to oxygen. Here, we present a 5.29-Mb assembly of its genome sequence. We have annotated 10 coding sequences (CDSs) for 1,3-propanediol fermentation and 18 CDSs for glycerol uptake. The CDSs related to virulence and by-product formation were also annotated.
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....
