“…When seeds are stored, Penicillium spp. can penetrate the wheat grain aleurone layer and endosperm cells, damage the germ, reduce vitality, contaminate with toxins, and change the colour of the seed (Chelkowski and Cierniewski 1983). Therefore, it would be most effective to treat the acorns before Penicillium penetration into deeper tissues.…”

Effective and environmentally friendly methods of protection to reduce seed contamination from fungi are constantly sought. The use of thermal impulses of 100 °C wet water steam to reduce fungal contamination has not been sufficiently investigated, and the potential of this physical approach has not been estimated.The aim of the study was to investigate what impact 100 °C wet water steam with different time durations had on acorn contamination with fungi, acorn germination and biometric indicators of English oak (Quercus robur) seedlings during the first year of growth. Different treatment durations with wet water steam were used: 2, 4, 6, 8, 10, 12 and 14 s.Research showed that 6 seconds impact of wet steam on the surface of the oak acorn destroyed Alternaria spp., 8 seconds impact destroyed Penicillium spp. and 14 seconds impact destroyed Mucor spp. Using 14 seconds water steam treatment Penicillium, Alternaria and Mucor spp. fungi were eliminated.Wet water steam treatment for 2 - 4 seconds not only stimulated the acorns germination by 4.0 - 7.6%, but also had positive influence on the root collar diameter of seedlings. Wet water steam treatment for 2 - 12 seconds had a positive effect on the root development of oak seedlings, however, high temperature environment had a suppressive effect on the oak seedling height.

“…Grain offers a nutrient rich and favourable growth environment for filamentous fungi (mould) as they can profit both from the nutrients secreted on the grain surface, or invade the endosperm of broken kernels and penetrate undamaged grain [3]. Mould growth in grain is influenced by the availability of water ( a w ), gas composition (O 2 and CO 2 ), and by the temperature of the storage environment.…”

A diploid and a haploid strain of Pichia anomala were tested for their biocontrol ability against the spoilage mould Penicillium roqueforti in glass tubes filled with grain at two water activities (aw). At aw 0.98, the two yeast strains grew and inhibited mould growth equally well and showed similar patterns of ethyl acetate production, reaching maximum values of 10-14 microg ml(-1) headspace. At aw 0.95, both growth and biocontrol performance of the haploid strain were reduced. Ethyl acetate formation was also substantially reduced, with maximum headspace concentrations of 4 microg ml(-1). We conclude that ethyl acetate is a major component of the anti-mould activity. The inhibitory effect of ethyl acetate was confirmed in a bioassay where the pure compound reduced biomass production of P. roqueforti.

Toxigenic Fusaria, producing zearalenone, appeared in 31% of cereal grain samples. However zearalenone was present only in 0.5% of 584 cereal samples assayed during 1979-1981 at level 0.2-1.2 mg/kg. Fungi able to form zearalenone were present mainly in grain collected from breeding stations. Fusarium culmorum was dominant among toxigenic isolates from domestic cereals and yield of zearalenone was up to 700 mg/kg.
