It was isolated from marine and freshwater sediments and can use acetylene (ethyne) as sole source of carbon and energy.[2] MetabolismP. acetylenicus can grow on acetylene, acetoin, ethanolamine, choline, propylene glycol (1,2-propanediol), or glycerol, although the latter two support growth only in the presence of small amounts of acetate. P. acetylenicus ferments substrates by disproportionation to acetate and ethanol or the respective higher acids and alcohols.[2]GenomeThe genomes of several strains have been sequenced. The genome of P. acetylenicus strain DSM 3247 was assembled into a 3,176,363-bp circular chromosome while strain DSM 3246 has a circular chromosome of 3,192,352-bp. Annotation of DSM 3246 identified 2,774 protein-coding genes, 16 rRNAs, 53 tRNAs, five noncoding RNAs, and 132 pseudogenes. DSM 3247 encodes 2,805 proteins, nine rRNAs, 51 tRNAs, five noncoding RNAs, and 44 pseudogenes.[3] References1. ^{{cite journal|last1=Parte|first1=A.C.|title=Pelobacter|website=www.bacterio.net|url=http://www.bacterio.net/pelobacter.html}} 2. ^1 {{Cite journal|last=Schink|first=Bernhard|date=1985-08-01|title=Fermentation of acetylene by an obligate anaerobe, Pelobacter acetylenicus sp. nov.|journal=Archives of Microbiology|language=en|volume=142|issue=3|pages=295–301|doi=10.1007/bf00693407|issn=0302-8933|url=http://nbn-resolving.de/urn:nbn:de:bsz:352-opus-25179}} 3. ^{{Cite journal|last=Sutton|first=John M.|last2=Baesman|first2=Shaun M.|last3=Fierst|first3=Janna L.|last4=Poret-Peterson|first4=Amisha T.|last5=Oremland|first5=Ronald S.|last6=Dunlap|first6=Darren S.|last7=Akob|first7=Denise M.|date=2017-02-09|title=Complete Genome Sequences of Two Acetylene-Fermenting Pelobacter acetylenicus Strains|journal=Genome Announcements|volume=5|issue=6|doi=10.1128/genomeA.01572-16|pmc=5331499|pmid=28183759}} External links
