Abstract Aspergillus strains were isolated from Hungarian mills in order to get information on the appearance of sterigmatocystin (ST) producing moulds, whose presence has never been demonstrated Hungary. Fungal isolates classified into nine morphotypes, sections Nigri , Nidulantes Versicolores (two morphotypes), Circumdati Flavi Clavati and Terrei by classical mycological assays. ST could be s...

background and aims: viral hepatitis is a global health problem with a high mortality rate. recently, a new flavi-like virus, provisionally named hepatitis g virus (hgv), has been described. hgv does not induce an immune response that is consistently detectable by using recombinant proteins from prokaryotic expression, therefore studies have been conducted by using polymerase chain reaction (pc...

Abstract Background The biological control mechanism of Aspergillus flavus (aflatoxigenic) strains in groundnuts with atoxigenic from the same species through competitive exclusion employed use endemic and well-adapted within agro-ecological zones Zimbabwe. selected elite non-aflatoxigenic isolates A. native to Zimbabwe were evaluated for their capability reduce aflatoxin contamination under la...

Plants of the genus Calathea possess many leaf colors, and they are economically important because they are widely used as ornamentals for interior landscaping. Physiological performances and photosynthetic capacities of C. insignis and C. makoyana were investigated. The photosynthetic efficiencies of C. insignis and C. makoyana were significantly increased when the photosynthetic photon flux d...
