“…Aspergillus flavus is one of the major spoilage organisms of intermediate moisture foods (Nielsen and Rios 2000;Batista et al 2003;González et al 2005). It is notable for the secondary metabolites (aflatoxins) that are potent hepatotoxins and carcinogens (Cullen and Newberne 1994;Roebuck and Maxuitenko 1994).…”

The cell-free culture filtrate (CCF) was prepared from a culture of an Aspergillus flavus antagonist, Bacillus subtilis B-FS06. The CCF inhibited the growth and spore germination of A. flavus at a series of concentrations (10, 25, 50%) (v/v). It still retained the activity after treatment at pH values ranging from 2 to 12 for 24 h or at 100°C for 30 min. The antifungal activity, however, was reduced by 30% after treatment at 121°C for 20 min. After purification by anion exchange chromatography, gel filtration chromatography and HPLC, the active compounds revealed six ion peaks: [M-H] m/z = 1006. 78, 1020.71, 1034.74, 1049.54, 1056.78, and 1071.64 by using electrospray ionization mass spectrometry (ESI-MS) analysis. In the presence of the active compounds at 200 lg/g, the growth of A. flavus on peanuts was completely inhibited.

KAČÁNIOVÁ, M., SUDZINOVÁ, J., KADÁSI-HORÁKOVÁ, M., VALŠÍKOVÁ, M., KRÁČMAR, S.:The determination of microscopic fungi from Chestnut (Castanea sativa Mill.) fruits, leaves, crust and pollen. Acta univ. agric. et silvic. Mendel. Brun., 2010, LVIII, No. 4, pp. 73-78 The plant-microbial interactive relations with respect to determination of the mycofl ora of the Castanea sativa Mill. nuts, crust, leaves and pollen and their eff ect on the host organism in four Slovak regions were studied. In the experiments were isolated 7 genera and 10 species of microscopic fungi from the nut, crust and leaves. It was found, that isolates from the Castanea sativa Mill. pollen were represented by 8 genera and 11 species of microscopic fungi. Alternaria, Cladosporium, Mucor and Rhizopus appeared to be the most frequently occurring genera of nuts, leaves and crust. Acremonium, Alternaria, Cladosporium, Fusarium, Penicillium and Trichoderma are the most frequently fungi of pollen. On the base of further taxonomic determination from the genera Aspergillus were isolated and identifi ed representatives of species A. fl avus, A. fumigatus, A. ochraceus, A. terreus and A. versicolor. From the genera Fusarium was isolated F. oxysporum and from Penicillium genera were isolated P. crustosum and P. glabrum. It is necessary to underline that the isolated genera Aspergillus, Fusarium and Penicillium are considered as the most important producers of mycotoxins.

“…But still more this question revealed about entomophilous pollen than anemophilous (Bogdanov, 2004(Bogdanov, , 2005González et al, 2005;Kačániová and Fikselová, 2007;Campos et al, 2008;Brovarskij and Brindza 2010;Brindza et al, 2010;Kačániová et al, 2011;Hani et al, 2012;Feás et al, 2012;Estevinho et al, 2012;Kačániová et al, 2014). These knowledges can be interesting from the point of view -microorganisms as an adjuvant factor of initiation of allergic immune responses; microbiological quality of pollen for its consumption as a source of nutrients and medicinal substances; the nature of the mutual relations of microorganisms/pollen grains.…”

“…The presence of endophytic bacteria in a tissue for extended periods of time suggests a possible symbiotic-like interaction (Madmony et al, 2005). Taking into account the nutrient content of pollen, it is a reliable and desired food source for a variety of microorganisms (González et al, 2005;Madmony et al, 2005). Also, an association microorganisms-pollen can protect microorganisms from environmental stresses (Madmony et al, 2005).…”

Quantitative microbiological analysis by dilution plating method of pollen and additional male and female catkins, leaves of Betula verrucosa Ehrh. and its two cultivars: 'Purpurea' and 'Youngii' relatively of fl owering period of Betula has been realized with the aim to provide new knowledge of the microbiological quality of anemophilous pollen for processing and its further application. Qualitative microbiological analysis with MALDI-TOF MS Biotyper was used in the identifi cation of aerobic, anaerobic mesophilic bacteria and coliforms. Mixed microbiota was determined, consisting of aerobic (4.68-4.89 log cfu/g) and anaerobic (3.30-3.48 log cfu/g) mesophilic bacteria, lactobacilli (0-3.48 log cfu/g), coliform bacteria (0-4.57 log cfu/g), fungi and yeast (3.78-3.95 log cfu/g) on the pollen grains, that indicates acceptable quality in comparison with the microbiological quality parameters for bee pollen. Pantoea agglomerans was found associated with pollen of Betula verrucosa Ehrh. Recommendations on the collection of anemophilous pollen were established.
