Aspergillus niger Assembly and Gene Annotation

About Aspergillus niger

Aspergillus niger is a mold classified within the Nigri section of the Aspergillus genus. The Aspergillus genus consists of common molds found throughout the environment within soil and water, on vegetation, in fecal matter, on decomposing matter, and suspended in the air. Species within this genus often grow quickly and can sporulate within a few days of germination. A combination of characteristics unique to A. niger makes the microbe invaluable to the production of many acids, proteins and bioactive compounds. Characteristics including extensive metabolic diversity, high production yield, secretion capability, and the ability to conduct post-translational modifications are responsible for A. niger's robust production of secondary metabolites. A. niger's capability to withstand extremely acidic conditions makes it especially important to the industrial production of citric acid.

The Department of Energy (DOE) Joint Genome Institute (JGI)](http://genome.jgi-psf.org/Aspni1/Aspni1.home.html) sequenced the genome of Aspergillus niger strain ATCC 1015 at 8.9X coverage using whole genome shotgun (WGS) sequencing. The version 3.0 of the assembly (June 30, 2008) contains 8 chromosomes, made up of 21 scaffolds, and 3 unmapped scaffolds. The 7 of the 8 chromosomes and 1 unmapped scaffold contain telomeres making A. niger's genome 34.85 MB in size.
