For phytoremediation two different plants, rye (Secale cereale) and nitrogen fixing blue fenugreek (Trigonella caerulea) were chosen and cultivated using 10 seeds in each pot.
In comparison, blue fenugreek cultivation had positive effect on TNT-degradation only in the variant with inoculum and amendments.
The second PCA axis separated samples according to the plant treatment; samples with blue fenugreek plants were discernible from both non-planted samples and from samples with rye cultivation.
Cultivation of blue fenugreek also enhanced the total abundance of Pseudomonas and Stenotrophomonas groups (up to 16.
Even though the cultivation of nitrogen-fixing blue fenugreek greatly enhanced the total bacterial abundance in soil, it had no significant enhancing effect on the overall proportions of the studied phylogenetic groups, resulting in less efficient removal of TNT.
Plants enhanced the total microbial community abundance, but in the case of blue fenugreek, cultivation did not significantly affect the TNT degradation rate.
It calls for fresh skimmed cow's milk to be blended with a special herb, Schabziger blue fenugreek
, which gives Sap Sago its soft herb-green hue and distinctive taste.
