Botany Department, Faculty of Science, Assiut University, Assiut, Egypt.

Fungal flora of 20 samples of lentil seeds collected from Assiut governorate, Egypt, were studied. Seventeen genera and 13 species were isolated on glucose- (15 genera and 27 species), cellulose- (15 genera and 25 species)- Czapek's agar media at 28 degrees C. The most common species were as follows: on glucose-Czapek's agar, Aspergillus fumigatus, A. niger, A. flavus, A. terreus, Penicillium notatum and Rhizopus oryzae and on cellulose agar, A. fumigatus, A. niger, A. flavus and P. notatum. Thin layer chromatographic (TLC) analysis and a biological test (Artemia salina) indicated the presence and the toxicity of aflatoxin in the extract of one sample (aflatoxins B1, B2, G1 and G2, at 20 mg/kg, total). This is the first report of the natural occurrence of aflatoxins in lentils.

UI	MeSH Term	Description	Entries
D007887	Fabaceae	The large family of plants characterized by pods. Some are edible and some cause LATHYRISM or FAVISM and other forms of poisoning. Other species yield useful materials like gums from ACACIA and various LECTINS like PHYTOHEMAGGLUTININS from PHASEOLUS. Many of them harbor NITROGEN FIXATION bacteria on their roots. Many but not all species of "beans" belong to this family.

D005658	Fungi	A kingdom of eukaryotic, heterotrophic organisms that live parasitically as saprobes, including MUSHROOMS; YEASTS; smuts, molds, etc. They reproduce either sexually or asexually, and have life cycles that range from simple to complex. Filamentous fungi, commonly known as molds, refer to those that grow as multicellular colonies.	Fungi, Filamentous,Molds,Filamentous Fungi,Filamentous Fungus,Fungus,Fungus, Filamentous,Mold
D000348	Aflatoxins	Furano-furano-benzopyrans that are produced by ASPERGILLUS from STERIGMATOCYSTIN. They are structurally related to COUMARINS and easily oxidized to an epoxide form to become ALKYLATING AGENTS. Members of the group include AFLATOXIN B1; aflatoxin B2, aflatoxin G1, aflatoxin G2; AFLATOXIN M1; and aflatoxin M2.	Aflatoxin
D001230	Aspergillus	A genus of mitosporic fungi containing about 100 species and eleven different teleomorphs in the family Trichocomaceae.
D012639	Seeds	The encapsulated embryos of flowering plants. They are used as is or for animal feed because of the high content of concentrated nutrients like starches, proteins, and fats. Rapeseed, cottonseed, and sunflower seed are also produced for the oils (fats) they yield.
