Filamentous fungi are important due to their high enzymes production potential. Many enzymes produced by fungi have related to biotechnological applications in several industrial sectors. The purpose of this study was to isolate filamentous fungi from different sources and to screen for amylases production potential. Fifteen fungal isolates of three genera, Aspergilus, Penicillium and Trichoder...

Goal. To develop a comparative correlation model of the interconnections ecological-trophic groups soil microorganisms with agrophysical, physicochemical indicators, humus condition, productivity degraded chernozem and to determine energy efficiency use intensive, low-intensive, organic fertilizer systems using by-products crops as fertilizers in 5-field grain-spray crop rotation for conditions...

Recently, strategies for controlling <i>Fusarium oxysporum</i> f. sp. <i>lycopersici</i> (<i>Fol</i>), the causal agent of Fusarium wilt tomato, focus on using effective biocontrol agents. In this study, an analysis and plant growth promoting (PGP) attributes 11 isolates loamy soil <i>Bacillus</i> spp. has been conducted. Among them, B.PNR1 B.PNR2...

Maltooligosaccharides, up to maltooctaose, were converted to the corresponding 4-nitrophenylhydrazones and in this form effectively resolved by paper chromatography. A method of determination of maltooligosaccharides in mixtures was elaborated which includes elution of the separated 4-nitrophenylhydrazones from the paper and their spectrophotometric measurement. The analytical procedure was emp...
