| aflatoxin b2: chemical identity and biological activity. | aflatoxin b(2), a blue-fluorescent metabolite of aspergillus flavus, was isolated from cultures grown on crushed wheat. chemical structure of the compound was elucidated as dihydroaflatoxin b(1). biological activity was determined in day-old male white pekin ducklings. the criteria of activity were reduction in growth and liver size and the extent of bile-duct hyperplasia. | 1963 | 14072177 |
| toxin-producing aspergillus isolated from domestic peanuts. | nine species of fungi isolated from stored domestic peanuts were grown in the laboratory on sterilized peanuts and were incorporated into diets fed to ducklings. symptoms of acute toxicity resulted only after consumption of one of the diets and this one contained material incubated with the fungus, aspergillus flavus link ex fries. | 1963 | 14077036 |
| toxin from aspergillus flavus: production on food materials of a substance causing tremors in mice. | a strain of aspergillus flavus produces, on foodstuffs, a substance which causes tremors and convulsions when administered to mice and certain other animals. the tremorgen, which differs from other recognized toxins attributed to this species, is associated with a distinct, dark spot on thin-layer chromatograms viewed under ultraviolet light. | 1964 | 14107473 |

| feeding of ferrets with the raw meat and liver of chickens chronically poisoned with toxic groundnut meal. | chickens were fed a ration containing 30 per cent of toxic groundnut meal for up to six weeks. the concentration of aflatoxin (toxic metabolites of aspergillus flavus) in the above ration was 3.06 p.p.m. at the end of 2nd, 4th or 6th week the birds were killed. the meat was removed from the bones and put through a meat grinder. the livers of three groups were pooled together. three control groups of birds kept on commercial pellets were treated similarly. female ferrets, two years of age, were u ... | 1965 | 14295993 |
| the effect of feeding toxic groundnut meal to chickens on oxidized pyridine nucleotides levels of liver and serum. | the extinction coefficient at 260 mmicro (e(260)) of the acid extracts of liver homogenates and sera of chickens were measured during six weeks of feeding with a ration containing 30 per cent groundnut meal contaminated with toxic metabolites of aspergillus flavus. the data indicated a significant depression of e(260) values of liver extracts following two weeks of consumption of the toxic ration. this lowered value returned to within the normal range after four weeks of feeding and remained at ... | 1965 | 14230910 |

| the transformation and resolution of 8-aza steroids by fungi. | 1. when (+/-)-8-aza-d-homo-oestrone 3-methyl ether was added to a culture of aspergillus ochraceus, the laevo-rotatory enantiomer is reduced to a 17a alcohol. thus (+/-)-8-aza-d-homo-oestrone 3-methyl ether has been resolved into both its components, the laevo-rotatory enantiomer being obtained by chromic acid oxidation of the alcohol, and the dextro-rotatory enantiomer as residual precursor from the fermentation. 2. fungi have been found to demethylate the 3-methyl ethers of 8-aza steroids to t ... | 1965 | 16749095 |
| aflatoxins: environmental factors governing occurrence in spanish peanuts. | aflatoxins are absent from freshly harvested peanuts although aspergillus flavus infest most of the kernels from pods having visible openings. microbial competition, governed by kernel moisture, limits aflatoxin content of kernels. the toxins are subject to microbial breakdown but the amount broken down is governed by initial aflatoxin concentration. | 1965 | 17748123 |

| aflatoxin production and degradation by aspergillus flavus in 20-liter fermentors. | yields of from 200 to 300 mg per liter of aflatoxins b(1) and g(1) were produced by two strains of aspergillus flavus in 20-liter fermentors under proper conditions of inoculum (well-dispersed growth) and aeration (0.5 volume per volume per min of air, 300 rev/min, 30 psi back pressure, baffles). peak yields were usually attained in 72 hr, after which the aflatoxin concentration declined rapidly. degradation of aflatoxin depended primarily on mycelial lysis and high-aeration conditions. cultures ... | 1966 | 5970470 |
| production of aflatoxins b1 and g1 by aspergillus flavus in a semisynthetic medium. | isolates of aspergillus flavus produced 0.2 to 63 mg of aflatoxins b(1) and g(1) per 100 ml in a nutrient solution consisting of 20% sucrose and 2% yeast extract. various factors influencing the fermentation were studied. the maximal amount of toxin was produced by atcc culture 15548 in 1-liter flasks containing 100 ml of medium incubated as stationary cultures for 6 days at 25 c. | 1966 | 5970823 |

| biological breakdown of benzylpenicillin by preformed mats of penicillin-producing organisms. | 1. penicillium chrysogenum and aspergillus flavus degraded benzylpenicillin in the same way. 2. degradation of the antibiotic was initiated by the cleavage of phenylacetic acid from 6-aminopenicillanic acid. 3. phenylacetic acid was left unchanged whereas 6-aminopenicillanic acid was degraded into cysteine and valine. this reaction is probably complex. 4. cysteine was not utilized but valine was cleaved into acetone and glycine. catabolism of valine by the preformed mats of the two moulds confir ... | 1966 | 16742463 |
| effect of aeration on growth and aflatoxin production by aspergillus flavus in submerged culture. | aspergillus flavus atcc 15517 produced up to 212 mg per liter of total aflatoxin in submerged culture in aerated (3,000, 6,000, 9,000, and 12,000 ml/min) and agitated medium in 14-liter fermentors with 10 liters of medium consisting of 2% yeast extract and 10% sucrose. aflatoxin production increased with time. a maximum of 212 mg/liter was produced at 9,000 ml/min aeration, whereas the yield decreased substantially at the lower aeration rates. two other strains of a. flavus synthesized aflatoxin ... | 1966 | 16349672 |
| aflatoxin production by aspergillus flavus as related to various temperatures. | two aflatoxin-producing isolates of aspergillus flavus were grown for 5 days on wort media at 2, 7, 13, 18, 24, 29, 35, 41, 46, and 52 c. maximal production of aflatoxins occurred at 24 c. maximal growth of a. flavus isolates occurred at 29 and 35 c. the ratio of the production of aflatoxin b(1) to aflatoxin g(1) varied with temperature. aflatoxin production was not related to growth rate of a. flavus; one isolate at 41 c, at almost maximal growth of a. flavus, produced no aflatoxins. at 5 days, ... | 1967 | 16349720 |

| effect of glucose on the oxidation of beta-nitropropionic acid by aspergillus flavus. | the rate of oxidation of beta-nitropropionic acid (bnp) to nitrate by replacement cultures of aspergillus flavus was linear. for each micromole of bnp assimilated, 1 mumole of nitrate was detected. bnp was readily oxidized at ph 3.8, but not at ph 6.8. in the presence of glucose, nitrate was not detected until after all of the glucose had been utilized. the effect of glucose is attributed to its inhibition of bnp uptake and also to its role as an electron donor for a nitrate reductase. | 1967 | 6027999 |
| aflatoxin-producing potential of isolates of the aspergillus flavus-oryzae group from peanuts (arachis hypogaea). | seventy-eight samples of farmer stock peanuts, representing peanuts grown in nine different geographical areas during 1964, were assayed for aflatoxin and examined for associated microflora. only two samples contained more than 50 ppb of aflatoxin. infestation by members of the aspergillus flavus-oryzae group varied from 35 to 100% of the kernels per area and from 1 to 100% of the kernels per sample. aflatoxin production by individual isolates ranged from 0 to 349,143 ppb under the test conditio ... | 1967 | 6031427 |
| production of aflatoxin on wheat and oats: measurement with a recording densitometer. | a method has been developed for the production of aflatoxin by growing aspergillus flavus nrrl 3145 on solid substrate wheat. optimal yields of 900 mug of aflatoxin g(1) and 900 mug of aflatoxin b(1) per g of substrate were obtained in 4 to 5 days at 28 c. a study of aflatoxin production on hulls and groats of oats and on whole oats by a. flavus strains nrrl 2999, nrrl 3000, and nrrl 3145 revealed that aflatoxin was produced on all three substrates, although production was very slight on hulls. ... | 1967 | 6031432 |
