Aspergillus aculeatus [1] is a fungus species in the genus Aspergillus . It has been implicated as the causative agent in plant disease. A. aculeatus belongs to the group of black Aspergilli which are important industrial workhorses. [2] [3] [4] A. aculeatus belongs to the Nigri section.

Aspergillus aculeatus is considered to be a ubiquitous species that could be usually isolated from rotting fruits and soil. Morphological characteristics such a color, size, shape and ornamentation of conidia are crucial for the classification of strains of black-spored Aspergillus species. Modern biochemical and molecular identification techniques are helpful in the identification of Aspergillus isolates, as black-spored Aspergillus species may have significant variations in their morphological and physiological characteristics.

Aspergillus can rapidly degrade cell walls of plants they infect, and isolates of A. aculeatus have been used to produce a number of important industrial enzymes, including cellulases, hemicellulases and proteases. These by-products are broadly used in the food and feed industries.

Due to its industrial value, the biochemical and catalytic properties of several hydrolases from A. aculeatus have been extensively studied. Also, structural studies using X-ray crystallography have been carried out on several polysaccharide degrading enzymes from Aspergillus aculeatus. (Luis M. Chong L.)

The genome of A. aculeatus was sequenced and published in 2010. The genome assembly size was 36.01 Mbp.

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.
