Rusul G.; E.G.zzar F.E.; Marth E.H., 1987: Growth and aflatoxin production by aspergillus parasiticus nrrl 2999 in the presence of acetic or propionic acid and at different initial ph values. Experiments were done to determine effects of different concentrations of acetic or propionic acid in a glucose-yeast extract-salts medium with an initial pH value of 4.5 or 5.5 on growth and aflatoxin production by Aspergillus parasiticus NRRL 29...

Buchanan, R.J.; Ayres, J., 1976: Effect of sodium acetate on growth and aflatoxin production by Aspergillus parasiticus NRRL 2999. Journal of food science: 41 (1) 128-132

E.G.zzar F.E.; Rusul G.; Marth E.H., 1987: Growth and aflatoxin production by aspergillus parasiticus nrrl 2999 in the presence of lactic acid and at different initial ph values. Twenty-five milliliters of glucose-yeast-salt medium containing 0, 0.5, 0.75, 1.0, 1.5 and 2.0% lactic acid with an initial pH of 3.5 or 4.5 were inoculated with 1 ml of a spore suspension containing 106 conidia of Aspergillus parasiticus NRRL 299...

Singh, S.N.; Chand, L., 1998: Effect of dimethyl sulfoxide and bavistin on growth, ergosterol and aflatoxin production by Aspergillus parasiticus NRRL 3240. Ergosterol and aflatoxins (B1, B2, G1 and G2) were found to increase with the age of A. parasiticus NRRL 3240 strains in synthetic high salt (SH) liquid medium. Dimethyl sulfoxide (DMSO) at 5.5 and 11.0 micro g/ml concentrations inhibited fungal g...

Reding, C.L.; Harrison, M.A., 1994: Possible relationship of succinate dehydrogenase and fatty acid synthetase activities to Aspergillus parasiticus (NRRL 5139) growth and aflatoxin production. Fatty acid synthetase (FAS) activity measured over time corresponded to aflatoxin B1 biosynthesis by A. parasiticus grown in minimal salts sucrose medium. Succinate dehydrogenase (SDH) activity, the primary metabolism indicator, decreased as FAS a...

Bhatnagar R.K.; Ahmad S.; Mukerji K.G.; Venkitasubramanian T.A., 1986: Nitrogen metabolism in aspergillus parasiticus nrrl 3240 and aspergillus flavus nrrl 3537 in relation to aflatoxin production. The relationship between nitrogen assimilation, metabolism and aflatoxin formation has been investigated in a toxigenic and a non-toxigenic strain of A. parasiticus. Ammonia from the medium is mainly assimilated via NADP-requiring glutamate dehydr...

Ratnavathi, C.V.; Sashidhar, R.B., 2007: Inhibitory effect of phenolics extracted from sorghum genotypes on Aspergillus parasiticus (NRRL 2999) growth and aflatoxin production. The inhibitory activity of bioactive polyphenols present in six sorghum genotypes - two red (AON 486 and IS 620), two yellow (LPJ and IS 17779) and two white (SPV 86 and SPV 462) varieties - on Aspergillus parasiticus (NRRL 2999) growth and aflat...

Tanuja, K.; Hemalatha, K.; Karuna, R.; Sashidhar Rao, B., 2010: Effect of various surfactants (cationic, anionic and non-ionic) on the growth of Aspergillus parasiticus (NRRL 2999) in relation to aflatoxin production. The effect of surfactants (two cationic, one anionic and three non-ionic) at 0.001, 0.01, 0.1 and 1.0 % concentrations on aflatoxin production, ergosterol content and sugar consumption by Aspergillus parasiticus (NRRL 2999) in YES liquid culture m...

Khan, S.N.; Venkitasubramanian, T.A., 1987: Cyclic AMP pool and aflatoxin production in Aspergillus parasiticus NRRL 3240 and Aspergillus flavus NRRL 3537. The relationship between levels of cyclic AMP, zinc and aflatoxin formation in Aspergillus parasiticus NRRL 3240 and Aspergillus flavus NRRL 3537 has been investigated. cAMP level was measured with the organism grown on SLS (synthetic) medium as w...

Praveen Rao, J.; Subramanyam, C., 1999: Requirement of Ca2+ for aflatoxin production: inhibitory effect of Ca2+ channel blockers on aflatoxin production by Aspergillus parasiticus NRRL 2999. Aflatoxin production by Aspergillus parasiticus NRRL 2999 was inhibited when Ca2+ channel blockers, i.e., verapamil and diltiazem (> 1 mmol 1(-1)), were included in the culture medium. Inhibition was not accompanied by growth inhibition, nor wa...
