In the present study, an iron(II)-nanoscale organic complex (Fe-NO) was used as enhancement factor by two different Rhodopseudomonas species of purple non-sulphur bacteria (PNSB) to produce hydrogen (H2). The Fe-NO synthesised using FeSO4·7H2O and Eucalyptus viminalis—a native Australian plant leaf extract—in a 1:2 2:1 concentration ratio. Besides, also source iron(II) for comparison with compl...

Natural compounds from certain timber trees are highly valued and recommended to protect wood and wood products against mold fungi. This study highlighted the use of some natural extracts and Paraloid B72 against the growth of two mold fungi, namely Alternaria tenuissima and Fusarium culmorum. From the in vitro experiment, the methanol extracts of Callistemon viminalis bark were effective again...

The objective of this study was to screen extracts of twenty Eastern European medicinal plants, using wild-type and reporter Chromobacterium violaceum bioassays, for novel components that target bacterial cells and their quorum sensing (QS) communication systems. Three types of activity and their combinations were revealed: (i) direct antimicrobial growth-inhibitory activity, (ii) non-specific ...

Whereas metal effects on plants have been well studied, much less is known about plant effects on metal mobilization in soils. We investigated metal mobilization and speciation with a resolution of a few cm in soil columns planted with willows (Salix viminalis). In the presence of plants, the concentration profiles of dissolved organic carbon (DOC), major ions (e.g., Ca), Cu, and Zn exhibited m...

اثر تغییرات فصلی در شکل ظاهری گیاهان خزان کننده به‌خوبی قابل مشاهده است. علاوه بر این، فرایندهای فیزیولوژیکی گیاهان خزان کننده و همچنین گیاهان همیشه سبز از فصلی به فصل دیگر دستخوش تغییراتی می‌شوند. افزایش و کاهش شدت عواملی نظیر درجه حرارت، خشکی و شوری موجب تغییر در فعالیت برخی آنزیمها می‌شود. گیاهان می‌توانند با تغییر در میزان فعالیتهای آنزیمی، خود را با شرایط محیط سازگار ‌نمایند. در این پژوهش ...
