Interactions between glyphosate and autochthonous soil fungi surviving in aqueous solution of glyphosate
The survival of autochthonous fungi in soil treated with 1mM aqueous solution of glyphosate was investigated. Significant differences in the total number of fungi in the studied objects were observed, and additionally significant qualitative changes were encountered. The dominating group of fungi belonged to genus Fusarium: Fusarium solani H30, Fusarium solani H50 and Fusarium oxysporum H80. Interactions between the isolated strains of fungi and varying concentrations of glyphosate were determined. The studied strains possessed high tolerance against the applied doses of glyphosate (0.5-2.0 mM). In the presence of glyphosate (as a sole source of phosphorus) applied in concentrations of 1.0-…
Influence of Galvanic Microcells on Growth of Pathogenic Bacteria and Candida Yeast
The aim of the study was to evaluate the influence of electrodes on growth of pathogenic bacteria and Candida albicans yeast. In the study, following references bacteria strains were used: Staphylococcus aureus ATTC 6538; Enterococcus faecalis ATTC 29212 (V); Enterococcus hirae ATTC 105441 (VI) and yeast strain Candida albicans ATTC 10231 (C40). Microelectrodes were prepared by ALCOR Center. Estimation of the biocidal effect of electrodes was carried out by medium poisoning method. The assessment of adhesion to the surface was performed by a modified Hawser’s method. Presence of adhesion was assessed by SEM analysis. The highest inhibition zones were obtained for Staphylococcus aureus ATTC …
