Aspergillus fischeri is a species of fungus in the genus Aspergillus. And is widely distribute in soil,[1] grain and canned food world wide. In the other hand Aspergillus fischeri is a BSL-1 plant pathogen.

About 64% of species in genus Aspergillus lack knowned sexual reproduction in their life cycle,[2] causing them were classfied into Fungi imperfecti before, producing the teleomorph name Neosartorya fischeri when the sexual reproduction were discoverd. But after the abolish of the Fungi imperfecti nomenclature, Aspergillus which is the anamorph name of should be the holomorph name when we discuss this species.

Reproduction

[edit]

The reproduction of Aspergillus fischeri could be divided into three way sexual, asexual and parasexual.

Asexual and parasexual are two nonsexual way when fungi reproducing. The distinction between them are where is the parent hyphae come from. When the mycelium comes from different individual occasionally fuse. The onset of fuse become the beginning of the parasexual stage.[3] And the two haploid nuclei from each mother cell will in one cell, dividing mitotically and experience random cross-over event until restore the haploid choromosome number.

There are two mating type when fungi reproducing when fungi reproduce in a sexual way. According to the number of mating type produced by individual, fungi thus to classfied into homothallic and heterothallic. And Aspergillus fischeri is homothallic, which can producing both mating type within one individuals.

Pathogenetic contrast to Aspergillus fumigatus

[edit]

Although Aspergillus fumigatus , which is highly relative with Aspergillus fischeri is the mainly pathogen of Aspergillosis. Aspergillus fischeri is regard as non-pathogenetic.

Recent research [4] has show that the difference between these two species, such as the progression when treating on immune depress rat. And find out that in most stress under common circumstance, Aspergillus fischeri survival rate is lower than Aspergillus fumigatus

Plastic degrading

[edit]

Members in Aspergillus are commonly used to survey the primary and secondary metabolism in fungi, for example, Aspergillus nidulans to be a type creature. And because of the exclusive range they can degrade, the name cell factory can be use to describe them. As the result, scientists have research many fungi that can degrde plastic. And find out Aspergillus fischeri can degrade Polycaprolactone (PCL).[5]
