What is aflatoxin B1 used for?

Aflatoxin B1 (AFB1) is one of the most potent carcinogens in foods, and it was postulated to account for the prevalence of hepatocellular carcinoma (HCC) in high exposure areas.

Is Aspergillus parasitic?

A number of species from the genus Aspergillus are facultative parasites and have been reported as agents of stonebrood (Shoreit and Bagy, 1995, Gilliam and Vandenberg, 1988).

What is the effect of Aspergillus flavus in the food industry?

Aspergillus flavus is a soil-borne opportunistic fungal pathogen that infects important agricultural crops such as maize, peanut, and cotton, and produces the most carcinogenic naturally occurring mycotoxin known as aflatoxin, which causes hundreds of millions of dollars in economic losses and serious illnesses in …

What is Aspergillus flavus complex?

Aspergillus flavus is an opportunistic pathogen of both plants and animals, and it produces one of the most potent naturally occurring carcinogens known. Developing seeds of corn, peanuts, cotton and tree nuts and many other crop plants are susceptible to infection by A. flavus under certain environmental conditions.

Is Aspergillus flavus and aflatoxin?

The main fungi that produce aflatoxins are Aspergillus flavus and Aspergillus parasiticus, which are abundant in warm and humid regions of the world. Aflatoxin-producing fungi can contaminate crops in the field, at harvest, and during storage.

What is Aspergillus flavus agar?

This chapter discusses Aspergillus flavus and A. parasiticus agar (AFPA) is a selective medium for the enumeration in foods of the mycotoxin producing fungi Aspergillus flavus and Aspergillus parasiticus.

Is Aspergillus parasiticus a carcinogen?

Aspergillus parasiticus is a plant pathogen that produces aflatoxins, a liver carcinogen. This fungus produces aflatoxins B1, B2, G1, G2, and mycotoxins, which are all potent carcinogens. Of these, aflatoxin B1 is considered to be the most potent, naturally occurring carcinogen known.

Does Aspergillus parasiticus produce norsoloronic acid?

Aspergillus parasiticus is a mold known to produce aflatoxins within the section Flavi. A mutant strain of Aspergillus parasiticus was reported as producing norsoloronic acid ( Lee et al., 1971 ). Norsoloronic acid was previously identified in another fungal strain, Aspergillus versicolor ( Hamasaki et al., 1967 ).

How long does it take for Aspergillus flavus to develop color?

Further formulation is refined, producing AFPA, which gives sufficient color development to enable recognition of Aspergillus flavus (or Aspergillus parasiticus) colonies within 42–48 h at 30º C.
