Ochratoxin A was quantitatively monitored in grain extracts by indirect solid-phase enzyme immunoassay with the use of an immobilized conjugate of the toxin with gelatin and polyclonal rabbit antibodies raised against the ochratoxin A-BSA conjugate.
This monitoring found that 1.7 to 18.5% of the samples were contaminated with the toxin at a concentration of 25.9-291.7 μg/kg.
It has been demonstrated in model experiments that the decrease in the content of BET in the culture fluid is accounted for by the toxin interaction with an attendant product, the exogenous metabolite (EM).
Primary Structure of a Short Toxin from the Venom of a Vietnamese Scorpion (Buthus sp.)
The complete amino acid sequence of an important toxin (toxin 14) from the venom of a Vietnamese scorpion (Buthus occitanus sp.) has been determined, which includes 35 amino acid residues and three disulfide bridges (molecular weight, 3843 Da).
Ecological mechanisms and prospects for utilization of toxins from parasitic hymenopterans
Insects in the order Hymenoptera defend themselves, attack prey and regulate hosts using toxins that are effective in small quantities.
In this study, advances in the researches on parasitic hymenopteran toxins are summarized in terms of the production, categories, components, properties, ecological functions and mechanisms.
The components of insect toxins are very complicated, and hymenopteran venoms contain alkanes, alcohols, aldehydes, ketones, organic acids, esters, lactones, proteins, polypeptides, enzymes, amines and other compounds.
Toxins of parasitic hymenoptera play an important adaptive role.
Eleven of these 17 phytotoxin producers belonged to the genus Pseudomonas.
Ozone is a gaseous pollutant and acts as a phytotoxin.
In vitro screening of rice germplasm for resistance to brown spot disease using phytotoxin
This is the first report about a disease resistant mutation obtained successfully in rice by tissue culture and in vitro screening with phytotoxin.
Embryogenic nucellar cultures of two polyembryonic mango cultivars, 'Hindi' and 'Carabao', were selected for resistance to the culture filtrate and phytotoxin of a virulent strain of Colletotrichum gloeosporioides Penz.
Tenuazonic acid, toxin of rice blast fungus, induces disease resistance and reactive oxygen production in plants
For barley, wheat, and potato somaclones have been found that were less susceptible to a toxin of Helminthosporium, fusaric acid, Fusarium coeruleum, F.
Differential responses of citrus calli and protoplasts to culture filtrate and toxin of Phoma tracheiphila
Pollen selection for Alternaria resistance in oilseed brassicas: responses of pollen grains and leaves to a toxin of A.
The effects of destruxin B, a host-specific toxin of Alternaria brassicae that causes black spot disease in oilseed brassicas, were studied on in vitro pollen germination and pollen-tube growth of Brassica campestris var "brown sarson", B.
