| aflatoxin and sterigmatocystin contamination of pistachio nuts in orchards. | aspergillus flavus and a. versicolor were both shown to be weak pathogens of developing pistachio fruits, producing aflatoxin and sterigmatocystin, respectively. aflatoxin concentrations approached those reported in cereal and legume seeds. fungus lesions on the first hulls were followed by invasion of seeds despite the sclerified shell. infections and mycotoxins present before harvest would presumably lead to further build-up after harvest if drying was slow or storage was under high humidity. | 1976 | 823868 |

| [peptidases of preparations of proteolytic enzymes from several species of bacteria, molds and actinomycetes]. | the activity of carboxy- and aminopeptidases of enzymic preparations obtained from bacteria bacillus subtilis 1 m, 17, bacillus mesentericus 100/26, 100/56, 16; pseudomonas aeruginosa 1/7a, 1/4; bacillus thermophilicus s. sp. nov b-22, moulds aspergillus oryzae 1-746, aspergillus flavus 716 and actinomycete streptomyces griseus 32-13 was studied. in the bacterial preparations the proteolytic activity was 1.5-2.5 times lower than in the fungal and actinomycete preparations. the carboxypeptidase a ... | 1976 | 825850 |
| [isolation of a toxicogenic strain of the fungus, aspergillus flavus, and characteristics of the produced aflatoxins]. | the authors demonstrate the production of the b1 aflatoxin by means of a strain of the fungus aspergillus flavus which was captured on cereal feed in spring 1975. besides the production of the mycotoxin, this fungus strain showed a very quick and intensive growth and development, in comparison with the laboratory strains of aspergillus flavus. the obtained and isolated aflatoxin b1 could be identified by chromatography and spectral photometry only when the fungus strain was cultivated on a suita ... | 1976 | 826000 |

| studies on the interaction between sclerotium bataticola and aspergillus flavus. | metabolic products of aspergillus flavus link had a toxigenic effect upon sclerotium bataticola maub., decreasing its radial expansion and dry weight and enhancing sclerotial production. metabolites of s. bataticola significantly lowered conidial output, slightly decreased the mycelial harvest but did not influence the linear spread of a. flavus. a. flavus, elaborating aflatoxin b1 (rf 0.56), showed fluorescent spots identical to the original but with lower rf value of 0.25 upon treatment with m ... | 1976 | 827707 |
| the stimulatory effect of kojic acid on the production of aflatoxin by isolates of aspergillus flavus link. | kojic acid at the levels of 0.01, 0.1, and 1.0% (w/v) was incorporated in the growth media of aspergillus flavus. in the presence of 0.01% of kojic acid, isolates i, ii, and iii produced 157, 113, and 135% aflatoxin, respectively, as compared to the control. at the highest level of kojic acid, i.e. 1%, aflatoxin production was inhibited to 74% in isolate i, but was little affected in isolate ii (104%) and strongly inhibited in isolate iii (54%). kojic acid, at a concentration of 0.1%, was still ... | 1976 | 827867 |
| toxicity of aspergillus flavus cultures isolated from egypt. | aflatoxin produced by 61.14% of the aspergillus flavus cultures, isolated from egypt. a wide potential range for aflatoxins b and g groups was obvious among the isolates. the concentration of aflatoxin b, produced by toxigenic cultures, ranged from 1,500 to 81,000 p.p.b. (mug/kg substrate), corresponding to 1,900 to 184,000 p.p.b. for aflatoxin g. however, 7.59% of the isolates produced more than 50,000 p.p.b. of aflatoxins b + g. | 1976 | 827868 |

(4) bothast and fennell (2) and reiss (5) for the detection of aflatoxin forming aspergillus flavus in bread was tested in comparison. the first two media allowed the most precise identification of this mold who was among eight common bread molds the sole producer of aflatoxins (as confirmed by thin-layer chromatography). because of its simple mode of preparation and handling the "aspergillus differential medium" (adm) of bothast and fennell (2) is rec ... | 1976 | 828368 |

| aflatoxin occurrence on raw and cooked york soybeans inoculated with three aspergillus isolates. | raw and cooked soybean media were inoculated in separate experiments with aspergillus flavus nrrl 3251, a. flavus atcc 15548, and a. parasiticus nrrl 2999 isolates. the toatl quantity of aflatoxins produced and the percentage distribution of aflatoxins b1, b2, g1, and g2 varied with the state of the medium (raw or cooked) and with the fungal isolate used. cooked soybean medium supported higher aflatoxin productions by a. flavus nrrl 3251 and a. parasiticus nrrl 2999 than did raw medium. larger q ... | 1976 | 944693 |
| fungal air spora at ibadan, nigeria. | the fungal air spora at ibadan, nigeria, was investigated by using casella slit samplers. three sites, incorporating three locations at each site, were selected for the exposure of replicate plates during sampling. to provide data on a wide range of saprophytic and pathogenic fungal spores, isolations were made on sabouraud dextrose agar and malt agar plates incubated at 26 and 37 c. altogether over 60,000 fungal colonies were isolated and counted during the 12-month sampling period. the prevale ... | 1975 | 1124919 |
| bright greenish-yellow fluorescence and aflatoxin in agricultural commodities. | the corn milling industry has widely accepted the presence of bright greenish-yellow fluorescence under a black light as a presumptive indicator of aflatoxin (a poison produced by the mold aspergillus flavus). this test was applied to wheat, oats, barley, rice, coconut, white corn, yellow corn, peanuts, sorghum, and soybeans, and evaluated in the laboratory. our study supported the use of bright greenish-yellow fluorescence as a presumptive test for aflatoxin in wheat, oats, barley, corn, and so ... | 1975 | 1172410 |
