Jual Culture Aspergillus niger Telp. 087731375234 Aspergillus niger is a fungi and one of the most common species of the genus Aspergillus. It causes a disease called black mould on certain fruits and vegetables such as grapes, apricots, onions, and   eanuts, and is a common contaminant of food. It is ubiquitous in soil and is commonly reported from indoor environments, where its black colonies can be confused with those of Stachybotrys (species of which have also been called "black mould"). Some strains of A. niger have been reported to produce potent mycotoxins called ochratoxins; other sources disagree, claiming this report is based upon misidentification of the fungal species. Recent evidence suggests some true A. niger strains do produce ochratoxin A. It also produces the isoflavoneorobol. A. niger is included in Aspergillus subgenus Circumdati, section Nigri. The section Nigri includes 15 related black-spored species that may be confused with A. niger, inc

Jual Culture dan Starter Aspergillus oryzae Telp. 087731375234 Aspergillus oryzae, along with most other members of the Aspergillus family, has a hyphae that is hyaline and septate, and conidiophore, which ends at a round-shaped vesicle. From the vesicle extend long filaments called a conodial chain, which appear as long fluffy strands on the surface of the substrate. The spore-bearing cells, or asci, are produced within the ascocarp, or the fruiting body. The primary enzyme secreted by the filamentous fungi is called amylase, which lends a sweet taste to the food it is fermented into. This enzyme is most efficient at a temperature of 35-40 degrees Celsius. Most other enzymes found in A. oryzae grow at a temperature of around 30-35 degrees Celsius. Members of the Aspergillus genus are distinct from other microbes due to the fact that they utilize both a primary and secondary metabolic system. The functionality of the Aspergillus metabolism depends on its carboxylic acids, wh
