纸浆和造纸工业(PPI)污泥中的重金属植物修复是通过在SaccharummunjaL.的根际区使用与根相关的Brevundimonassp(PS-4MN238722.1)进行解毒的。该研究旨在研究SaccharummunjaL.通过细菌相互作用去除重金属的效率以及理化参数。PPI污泥的理化检查显示生化需氧量(8357±94mgkg-1),电导率(2264±49μmhoscm-1),总酚(521±24mgkg-1),总溶解固体(1547±23mgkg-1),总氮(264±2.13mgkg-1),pH值(8.2±0.11),化学需氧量(34756±214mgkg-1),颜色(2434±45Co-Pt),总悬浮固体(76±0.67mgkg-1),硫酸盐(2462±13mgkg-1),氯青素(597±13.01mgkg-1),K+(21.04±0.26mgkg-1),总固体(1740±54mgkg-1),磷,Cl-,Na+。重金属,如铁,其次是锌,Mn,Cd,Cu,Ni,Pb,As,Cr和Hg高于允许的限度。甘蔗的根和芽显示出最高的Cd浓度,其次是Mn,Ni,Fe,Zn,Cu,As,Cr,Hg,和Pb。测试金属(Fe,Mn,Pb,Cd,Cr,Cu,Zn,Ni,As,和Hg)的生物积累和易位因子也分别显示为<1和>1,证明这些植物具有相当大的吸收和转运能力。促进植物生长的活动,如木质素分解酶,水解酶,吲哚乙酸,和Brevundimonassp.的铁载体生产活性。(PS-4MN238722.1)也注意到更高。这些发现支持将Brevundimonassp(PS-4MN238722.1)与SaccharummunjaL.植物结合使用,作为污染地区工业污泥的跨学科管理,以防止工业场地附近的土壤。
Heavy metals phytoremediation from pulp and paper industry (PPI) sludge was conducted by employing root-associated Brevundimonas sp (PS-4 MN238722.1) in rhizospheric zone of Saccharum munja L. for its detoxification. The study was aimed to investigate the efficiency of Saccharum munja L. for the removal of heavy metals along with physico-chemical parameters through bacterial interactions. Physico-chemical examination of PPI sludge showed biochemical oxygen demand (8357 ± 94 mg kg-1), electrical conductivity (2264 ± 49 μmhoscm-1), total phenol (521 ± 24 mg kg-1), total dissolve solid (1547 ± 23 mg kg-1), total nitrogen (264 ± 2.13 mg kg-1), pH (8.2 ± 0.11), chemical oxygen demand (34756 ± 214 mg kg-1), color (2434 ± 45 Co-Pt), total suspended solid (76 ± 0.67 mg kg-1), sulphate (2462 ± 13 mg kg-1), chlorolignin (597 ± 13.01 mg kg-1), K+ (21.04 ± 0.26 mg kg-1), total solid (1740 ± 54 mg kg-1), phosphorous, Cl-, and Na+. Heavy metals, such as Fe followed by Zn, Mn, Cd, Cu, Ni, Pb, As, Cr and Hg were above the permissible limit. Root and shoot of Saccharum munja L. revealed highest concentrations of Cd followed by Mn, Ni, Fe, Zn, Cu, As, Cr, Hg, and Pb. Tested metals (Fe, Mn, Pb, Cd, Cr, Cu, Zn, Ni, As, and Hg) bioaccumulation and translocation factors were also revealed to be < 1 and >1, respectively, demonstrating that these plants have considerable absorption and translocation abilities. Plant growth-promoting activity, such as ligninolytic enzymes, hydrolytic enzymes, indole acetic acid, and siderophore production activity of Brevundimonas sp. (PS-4 MN238722.1) were also noted to be higher. These findings support the use of Brevundimonas sp (PS-4 MN238722.1) in combination with Saccharum munja L. plant as interdisciplinary management of industrial sludge at polluted areas for the prevention of soils near the industrial site.
