Our results demonstrate the power of single cell genomics to reconstruct representative microbial genomes from complex communities, independent of their cultivability.
They found that the microbial genomes from some patients differed widely from one another, just as you'd expect with environmental infections.
However, the application of novel cultivation strategies is slow and will not enable cultivation of the extant diversity of microbial genomes from extreme environments, necessitating new approaches to exploit natural products from as-yet-uncultured microbes for industrial application (Daniel 2004).
The studies open up new opportunities to uncover microbial genomes from other environments, revealing how microbes alter global carbon and nitrogen cycles, how microbial metabolism evolved, and how so many different kinds of microbes can coexist, says biological oceanographer Paul Falkowski of Rutgers University in New Brunswick, New Jersey.
We obtained data relating to the GC content, genome size, number of replicons, number of rRNAs and number of tRNAs for a sample of 895 microbial genomes from the Genome Atlas Database (http://www.cbs.dtu.dk/services/GenomeAtlas-3.0/).
Despite these recent reports that indicate significant progress by integrating Illumina and 454 technologies, complete de novo assembly of microbial genomes from only short reads and without aid from Sanger sequencing still remains an unsolved challenge.
IMG/M integrates metagenome datasets with isolated microbial genomes from the IMG system.
The simulated communities consist of 113 microbial genomes from a collection of genomes given by the FAMeS dataset [ 45, 46].
IMG/M provides support for such analyses by integrating metagenome datasets with isolated microbial genomes from the IMG system [23].
The lacking of sufficient reference genomes and also the computational burden of assembling microbial genomes from metagenome data hinders the wider application of such technology.
