“…Due to the different cell wall structures, Bacillus subtilis is more likely to bind with metals than gram-negative bacterium. Teichoic acid associated with the cell wall is unique to gram-positive cells, and its phosphate group is a key component of metal uptake [ 2 , 37 ]. In this study, the soil available Cd concentration decreased by 74.34% ( P < 0.05 ) after the application of compound Bacillus biofertilizer with Bacillus as the main component (Fig.…”

“…Soil enzyme activity is an important biological indicator to evaluate soil quality, especially to the evaluation of soils contaminated by heavy metals [ 39 ]. The urease, alkaline phosphatase, and catalase are the most sensitive to heavy metals [ 2 , 40 ]. Microorganisms secrete large amounts of urease.…”

“…The decomposition of urease and the formation of bicarbonate, ammonium, and hydroxyl ions could increase the pH. All the urease-producing isolates could increase the pH of medium, which may greatly impact the bioavailability of soil heavy metals [ 2 ]. The reason for the decrease of soil enzyme activity after the application of exogenous Cd is that the molecular reaction between heavy metals and enzyme-substrate complexes or protein active groups denatures enzyme protein and reduces enzyme activity [ 41 , 42 ].…”

Background Cd seriously threatens soil environment, remedying Cd in farmland and clearing the response of soil environment to modifiers in Cd-contaminated soils is necessary. In this study, the effects of cotton straw biochar and compound Bacillus biofertilizer used as modifiers on the biochemical properties, enzyme activity, and microbial diversity in Cd-contaminated soils (1, 2, and 4 mg·kg−1) were investigated. Results The results showed that both cotton straw biochar and compound Bacillus biofertilizer could improve the soil chemical characteristics, including the increase of soil C/N ratio, electrical conductance (EC) and pH, and the most important decrease of soil available Cd content by 60.24% and 74.34%, respectively (P < 0.05). On the other hand, adding cotton straw biochar and compound Bacillus biofertilizer in Cd stressed soil also improved soil biological characteristics. Among them, cotton straw biochar mainly through increasing soil alkaline phosphatase activity and improve bacteria abundance, compound Bacillus biofertilizer by increasing soil invertase, alkaline phosphatase, catalase, and urease activity increased bacterial community diversity. On the whole, the decrease of soil available Cd was mainly caused by the increase of soil pH, C/N, urease and alkaline phosphatase activities, and the relative abundance of Acidobacteria and Proteobacteria. Conclusions In summary, the applications of cotton straw biochar and compound Bacillus biofertilizer could decrease soil available Cd concentration, increase soil bacterial community diversity and functions metabolism, and reduce the damage of Cd stress, compared with cotton straw biochar, compound Bacillus biofertilizer was more effective in immobilizing Cd and improving soil environmental quality.

“…The bioaccumulation of metals, as a result of chronic exposure, within humans could lead to an array of physical and mental disorders. Moreover, the increased concentrations of heavy metals in the soil can considerably affect important soil functions as well as soil microbiological and biochemical properties resulting in the reduction of plants' growth, performance, and yield (Tauqeer et al, 2021).…”

2400 mg/kg), pH (8.3-8.7), COD (39-1995 mg/ kg), and sulfate levels (17.8-301.6 mg/kg) were altered by the dumpsites. Heavy metal concentrations varied between dumpsites; however, the most commonly prevalent metals across all dumps were Fe (992-41,500 mg/kg), Cr (17.4-139.5 mg/kg), Zn (24.1-177.4 mg/kg), Cu (9.42-148.2 mg/kg), and Mn (25.2-776.5 mg/kg), though recorded concentrations exceeded permissible limits only in certain instances. Evidently, soil samples collected at dumpsites had higher concentrations compared to the samples collected away from dumpsites reaching 27 times more in certain locations. The altered parameters have a direct effect on soil fertility and, if biomagnified, could disrupt crop yields and impact human health. Physiochemical properties and heavy metal concentrations in water samples were not significantly altered and were found to be within permissible limits. However, it is crucial to develop a monitoring and remediation plan to decrease the percolation of leachate to water resources.

“…One of the most widely used techniques for the remediation of soils contaminated with heavy metals involves reducing mobilization by means of an organic or inorganic sorbent. Indeed, there are several recent publications related to these applications (Tauqeer et al, 2021a(Tauqeer et al, , 2021bTuran, 2021). Microorganism-based technologies are considered to be feasible alternatives for this purpose, since the physical and chemical treatments of heavy metalcontaining effluents is often expensive and generates large amounts of sludge and cannot usually be used to treat metal concentrations below 100 mg L −1 (Volesky, 2007).…”

The treatment of metal-polluted wastes is a challenging issue of environmental concern. Metals can be removed using microbial biomass, and this is an interesting approach towards the design of eco-friendly technologies for liquid waste treatment. The study reported here aimed to optimize nickel and cobalt biosorption from aqueous solutions using three native metal–resistant Serratia marcescens strains. Ni(II) and Co(II) biosorption by S. marcescens strains was found to fit better to Langmuir’s model, with maximum uptake capacities of 13.5 mg g−1 for Ni(II) ions and 19.9 mg g−1 for Co(II) ions. Different experimental conditions of initial metal concentration, pH, initial biomass, and temperature were optimized using the Plackett–Burman method, and, finally, biomass and metal concentration were studied using the response surface methodology (RSM) to improve biosorption. The optimum uptake capacities for Co(II) ions by the three biosorbents used were obtained for initial metal concentrations of 35–40 mg L−1 and an initial biomass of 6 mg. For Ni(II) ions, the optimum uptake capacity was achieved with 1 mg of initial biomass for S. marcescens C-1 and C-19, and with 7 mg for S. marcescens C-16, with initial concentrations of 20–50 mg L−1. The results obtained demonstrate the viability of native S. marcescens strains as biosorbents for Ni(II) and Co(II) removal. This study also contributes to our understanding of the potential uses of serpentine microbial populations for the design of environmental cleanup technologies.
