US EPA ATTACHMENT I--FINAL RISK ASSESSMENT FOR Aspergillus niger

(February 1997) I INTRODUCTION Aspergillus niger is a member of the genus Aspergillus which includes a set of fungi that are generally considered asexual although perfect forms (forms that reproduce sexually) have been found Aspergilli are ubiquitous in nature

What is Aspergillus niger used for?
Aspergillus niger is one of the most important microorganisms used in biotechnology. It has been in use already for many decades to produce extracellular (food) enzymes and citric acid. In fact, citric acid and many A. niger enzymes are considered GRAS by the United States Food and Drug Administration.
Can Aspergillus niger cause pneumonia?
J Med Microbiol. 2010 Jul; 59 (Pt 7): 834–838. Infections due to Aspergillus species cause significant morbidity and mortality. Most are attributed to Aspergillus fumigatus, followed by Aspergillus flavus and Aspergillus terreus. Aspergillus niger is a mould that is rarely reported as a cause of pneumonia.
Does aspergil Niger produce aflatoxins?
Despite the long history and intensive nature of Aspergil-lus research, only few cases of toxin formation by A. ni-ger have been reported. However, in no case has A. niger been proven to produce aflatoxins or trichotecenes. Two reports (Kulik and Holaday 1966; Hanssen 1969) that A. niger cultures produced aflatoxin B1 have been disproved.
Does Aspergillus niger produce citric acid?
