“…There are more and more reports about the spread and harmful manifestation of Alternaria blight in various crops [11][12][13][14][15][16], in this connection, the study of the features of pathogenesis and the development of measures to combat these diseases is becoming more relevant. The world is actively searching for effective producers of biological products -strains of antagonistic bacteria.…”

Species of the genera Bacillus Cohn and Pseudomonas Migula are successfully used as biocontrol agents for many mycopathogens, including Alternaria sp. To assess the bacteria antagonistic potential against Alternaria sp, we used the method of counter cultures on various nutrient media – universal and specialized. Of the 24 bacterial strains of the genus Bacillus, 18 strains were developed antagonistic activity to Alternaria sp. after 10 days of co-cultivation on the Tylona-3 medium. The maximum sterile zone (8.0 mm) was formed by bacterial strains (R-9, 5B-1, 01 cor f Bacillus sp.). 3 strains of 9 bacteria of the genus Pseudomonas, developed antagonistic activity to Alternaria sp. on Kinga B medium - 14-3 Pseudomonas sp., Oif 2-1 Pseudomonas sp., 14-4 Pseudomonas sp. The maximum antibiotic activity on potato-sucrose agar was established in strains 3-3 Bacillus sp., and K 1-1 Bacillus sp. (sterile zone 7.5 mm). All the tested bacteria most often caused one sign of antagonism – antibiosis.

“…Among Alternaria species, especially Alternaria (A.) alternata and A. tenuissima are frequently associated with several plant diseases of small grain cereals (black point, kernel and leaf blight) [7,8,9,10] and both of them are capable to produce a variety of mycotoxins [8,9,10,11,12,13]. Alternaria toxins can be grouped into five different structural classes: dibenzopyrone derivatives—alternariol (AOH), alternariol monomethyl ether (AME) and altenuene (ALT); tetramic acid derivatives—tenuazonic acid (TeA) and iso-tenuazonic acid (iso-TeA); perylene derivatives—altertoxins I (ALX-I), altertoxin II (ALX-II) and alertoxin III (ALX-III) and stemphyltoxin III, a cyclic tetrapeptide—tentoxin (TEN) and Alternaria alternata f. sp.…”

Alternaria toxins are mycotoxins produced by various Alternaria species which, besides the Fusarium species, represent the principal contaminants of wheat worldwide. As currently, only limited information on the behaviour of Alternaria toxins during processing of cereals is available, the objective of this study was to investigate the effect of the dry milling process of wheat on Alternaria toxins distribution. Alternariol (AOH), alternariol monomethyl ether (AME) and tenuazonic acid (TeA) content were analysed by high performance liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) in all milling fractions of untreated (control), fungicide-treated, Alternaria tenuissima inoculated and commercial wheat sample. After dry milling process, in last break and milling flows and by-products, increased concentration of examined Alternaria toxins was detected. TeA was quantified in almost all milling fractions in all tested wheat samples, while AOH and AME were detectable mostly in last break and milling flows and by-products. In respect to the contamination with Alternaria toxins, white flour can be considered as relatively safe product. Since Alternaria toxins are concentrated mainly in the peripheral parts of the kernel, a special attention should be given to their content in low-grade flours and milling by-products.
