The biosorption of heavy metals has become an attractive alternative to conventional methods and is considered feasible, environmentally friendly often low-cost option. Five microorganisms (Rhodotorula sp., Cladosporium Bacillus megaterium, Trichosporon sp. Geotrichum sp.) were isolated from different environments used for the Cd(II) aqueous solutions in batch mode expand upon existing studies generate new data related main that could be successfully applied removal wastewaters. Considering a constant biosorbent dose (5 g/L), pH (5.4) temperature (25 °C) varying contact times initial pollutant concentrations, process efficiency uptake capacity biosorbents assessed. Statistical analysis experimental results revealed time longer than 24 h did not significantly increase or by B. megaterium which means available binding sites on cell wall immediately participate metal ions. For other three biosorbents, increasing 48 led significant efficiency. A comparison values each had highest (8.53 mg/g), followed (8.21 mg/g). lowest capacity, as well after contact, was obtained (0.73 mg/g 14.97%, respectively). FTIR almost all functional groups present surface biosorbent, but their involvement differed biosorbent. phosphodiester, amide hydroxyl found Rhodotorula involved biosorption.

AbstractSoil pollution from potentially toxic elements (PTEs) is a serious environmental issue worldwide that affects agricultural safety and human health. Arbuscular mycorrhizal fungi (AMF), as ecosystem engineers, can alleviate PTE toxicity in crop plants. However, the comprehensive effects of AMF on performance PTE-contaminated soils have not yet been recognized globally. Here, meta-analysis 153 studies with 3213 individual observations was conducted to evaluate growth accumulation five staple crops (wheat, rice, maize, soybean, sorghum) contaminated soils. Our results demonstrated had strong positive shoot root biomass. This because effectively oxidative damage induced by PTEs stimulating photosynthesis, promoting nutrition, activating non-enzymatic enzymatic defense systems also decreased 23.6% increased 0.8%, demonstrating inhibited transfer uptake shoot. Meanwhile, AMF-mediated were weaker pH > 7.5. Overall, this global survey has essential implications ability enhance provides insights into guidelines for safe production worldwide.Keywords: fungipotentially elementscrop growthbioaccumulationphysiological activitiesmeta-analysisHANDLING EDITORS: Jörg Rinklebe Lena Q.

Amendments with activators or microorganisms to enhance phytoremediation in toxic-metal-polluted soils have been widely studied. In this research, the production of indoleacetic acid, siderophore, and 1-aminocyclopropane-1-carboxylate (ACC) deaminase by phosphate-solubilizing bacteria was investigated during a pure culture experiment. Pot experiments were performed using Cd-polluted soil following treatments: control (CK, only ultrapure water), orange-peel-based activator (OG), combination (Acinetobacter pitti) OG (APOG). Ryegrass plant height fresh weight, Cd content ryegrass, total available content, enzyme activity, bacterial diversity determined work.
