Benefits of technology

[0007]Systems and methods of the present invention provide for efficient production of renewable energy and other carbon-based products of interest (e.g., fuels, sugars, chemicals) from C1 compounds. Furthermore, systems and methods of the present invention can be used in the place of traditional methods of producing chemicals such as olefins (e.g., ethylene, propylene), which are traditionally derived from petroleum in a process that generates toxic by-products that are recognized as

Problems solved by technology

However, the algae-based production of carbon-based products of interest relies on the relatively inefficient process of photosynthesis to supply the energy needed for production of organic compounds from carbon dioxide [Larkum, 2010].
Moreover, commercial production of carbon-based products of interest using photosynthetic organisms relies on reliable and consistent exposure to light to achieve the high productivities needed for economic feasibility; hence, photobio

Optimization of Growth Medium for Paracoccus sp. when Using Formate as the C1 Compound

[0257]Paracoccus zeaxanthinifaciens ATCC 21588, Paracoccus versutus ATCC 25364, and Paracoccus denitrificans ATCC 13534 were obtained from the American Type Culture Collection (ATCC).

[0258]Strains were tested for the ability to grow aerobically on sodium formate as a sole source of carbon and / or energy using MOPS minimal medium (Teknova, Inc.) with sodium formate as a sole carbon source at 37C. Unlike previous media used to evaluate the formate-dependent growth of Paracoccus, this medium contains defined levels of trace elements molybdenum, boron, copper, zinc, manganese, and other trace metals.

[0259]Growth was conducted in various high-throughput machinery capable of monitoring growth by light scattering at 600 nm, including a Gemini SpectraNax plate reader (Molecular Devices, Inc.), a Tecan M3000 plate reader (Tecan, Inc.), and a BioLector device (m2p-labs, Inc.). For the BioLector, the ...

Automatable Protocol for Conjugative Transfer of Plasmids from E. coli Donors to Paracoccus sp

[0267]E. coli strain 517-1 was obtained from the Yale E. coli Genetic Stock Center. Paracoccus denarificans PD1222 was obtained from Stephen Spiro (University of Texas at Dallas). E. coli S17-1 strain is tra+, meaning it is able to mobilize for conjugative transfer those plasmids harboring a mob+genotype. Plasmid pDIY313K, obtained from Dariusz Bartosik (University of Warsaw, Poland) and described by his laboratory [J Microbiol Methods, 2011, 86(2):166-74, DOI: 10.1016 / j.mimet.2011.04.016], and introduced into E. coli 517-1 by standard methods.

[0268]E. coli S17-1 was grown on Luria broth with carbenicillin overnight. Paracoccus versutus ATCC 25364 was grown overnight on MOPS minimal medium (Teknova, Inc.) with 50 mM sucrose and 40 mM sodium nitrate.

[0269]The next day, E. coli S17-1 was subcultured in antibiotic-free Luria broth for >4 hr. Paracoccus strains were subcultured in iden...

Genome Sequencing of Paracoccus Strains

[0272]Genomic DNA was isolated from Paracoccus zeaxanthinifaciens ATCC 21588, Paracoccus versutus ATCC 25364, and Paracoccus denitrificans ATCC 13534 using a Wizard Genomic DNA Isolation Kit (Promega, Inc.). The resulting DNA samples were fragmented and converted to paired-end libraries for whole-genome shotgun sequencing on a 454 pyrosequencing platform (Roche, Inc.).

[0273]For Paracoccus denitrificans, 37,585,886 paired reads, each 100 nt in length, were obtained. This represents approximately 3.7 gigabases of sequence data, or approximately 730-fold coverage of the 5.2 megabase genome of Paracoccus denitrificans PD1222 (Genbank accession numbers CP000489, CP000490, and CP000491 for chromosome 1, chromosome 2, and a 653,815 bp megaplasmid, respectively). Reads were assembled first by de-novo assembly and second by mapping the de-novo contigs to the published PD1222 genome.

[0274]The resulting reads could be assembled into a crude whole...

Abstract

The present disclosure identifies pathways, mechanisms, systems and methods to confer production of carbon-based products of interest, such as sugars, alcohols, chemicals, amino acids, polymers, fatty acids and their derivatives, hydrocarbons, isoprenoids, and intermediates thereof, in engineered and/or evolved methylotrophs such that these organisms efficiently convert C1 compounds, such as formate, formic acid, formaldehyde or methanol, to organic carbon-based products of interest, and in particular the use of organisms for the commercial production of various carbon-based products of interest.

Description
