Analytical characterization methods including SEM, FT-IR, TGA/DTG, and XRD were used to analyze the studied samples. The images of the extracted lignin displayed a rough feature. After functionalization of lignin with branched polyethyleneimine, the surface became rougher with the presence of many cavities.

The XRD diffractograms revealed a wide area under the curve, confirming the amorphous characteristic of the lignin samples. The functionalization with branched polyethyleneimine does not affect the crystallinity of lignin. TGA/DTG exhibited several degradation stages in a wide range of degradation temperature due to the complex molecular structure of lignin. The thermal decomposition of the modified lignin samples occurred at more elevated temperature values compared to unmodified extracted lignin.

This study aimed to develop metal-resistant microbial consortium loaded biochar (MCLB) by inoculating tannery solid waste biochar (BC) with consortium of ten <i>Bacillus</i> and/or five <i>Trichoderma</i> strains and their effect was evaluated on the morphological and biochemical attributes of sunflowers including metals immobilization. The soil amendment with BC at 2% rate improved the shoot height, dry biomass, and chlorophyll content in sunflowers but not in higher doses. However, the application of MCLB even at its highest concentration <i>i.e.,</i> 10% dose showed a significant increase in shoot length (61.2%) and dry weight (656.9%) over BC only. The findings of metal bioavailability indicated that the application of MCLB having metal-resistant strains decreased the mobility of Cd, Cr, Cu, Ni, Pb and Zn into the sunflower tissues compared to BC. Moreover, MCLB enhanced the uptake of Fe and Mg which are beneficial to the plant. In addition to that, the results for phenolic and proline content demonstrated a considerable decrease by MCLB indicating less stress response as compared to BC. Therefore, these findings highlight the potential of MCLB as a sustainable soil amendment for improving the growth attributes of oil-yielding sunflower varieties by using tannery solid waste biochar while decreasing the uptake of nonessential metals.
