“…Co-inoculation of B. velezensis and some PGPMs (such as Pseudomonas putida , Bradyrhizobium japonicum , Bacillus pumilus , Bacillus licheniformis , Trichoderma harzianum ) showed greater promoting effects on crops (tomato, soybean, wheat) than monocultures ( He et al, 2019 ; Oliveira et al, 2019 ; Sheteiwy et al, 2021 ). B. diminuta is commonly used for heavy metal remediation, antibiotic degradation and oil degradation ( Wang et al, 2016 ; Liu et al, 2017 ; Rathi and Yogalakshmi, 2021 ; Ali et al, 2022 ). Some works also showed that it could promote the growth of tobacco ( Shao et al, 2015 ).…”

Microbial inoculation with plant growth-promoting microorganisms (PGPMs) is one of the most promising technologies to solve the current global challenges. Co-inoculants is more efficient and stable than mono-inoculants. However, the growth promoting mechanism of co-inoculants in complex soil system is still poorly understood. In this study, the effects on rice, soil and the microbiome of the mono-inoculant Bacillus velezensis FH-1 (F) and Brevundimonas diminuta NYM3 (N) and the co-inoculant FN obtained in previous works were compared. Correlation analysis and PLS-PM were used to explore the primary mechanism of different inoculants promoting rice growth. We hypothesized that inoculants promoted plant growth (i) by themselves, (ii) by improving soil nutrient availability or (iii) by regulating the rhizosphere microbiome in complex soil system. We also assumed that different inoculants had different ways of promoting plant growth. The results showed that FN significantly promoted rice growth and nitrogen absorption and slightly increased soil total nitrogen and microbial network complexity compared with F, N and the control (CK). B. velezensis FH-1 and B. diminuta NYM3 interfered with each other’s colonization in FN. FN increased the complexity of the microbial network compared to F and N. The bacterial community of FN was quite different from CK and N, while the fungal community was not significantly different from other treatments. The species and functions enriched or inhibited by FN are part of F. The correlation analysis and PLS-PM results showed that inoculants (F/N/FN) promoted the growth of rice mainly by regulating the rhizosphere microbiome rather than by themselves or by improving soil nutrient availability. Co-inoculant FN promotes rice growth specifically by enhancing microbial nitrification function through enriching related species compared with F or N. This may provide theoretical guidance for the construction and application of co-inoculants in the future.

The adhesion of bacteria on clay surfaces strongly affected their migration and distribution in soil and water. Bacterial adhesion experiments on the Na-montmorillonite (Na-MMT) surface were conducted to determine the role of Na-MMT in the bacterial adhesion process and to prove the validity of the isotherm and kinetic theory for the bacterial surface adhesion in the presence of Ca2+ ions. Batch adhesion experiments with bacteria on the Na-MMT surface were carried out with varying time frames, temperatures, bacterial concentrations, and Ca2+ ion concentrations. The adhesion capacity of Na-MMT significantly correlated with the Ca2+ ion concentration, temperature, time frame, and bacterial concentration when Ca2+ ions were present. The adhesion morphology of the bacteria onto the Na-MMT surface, observed through the zeta-potential and atomic force microscopy (AFM), additionally demonstrated that the bacterial adhesion onto the Na-MMT surface was dominated by the nonelectrostatic force.

“…Nowadays there are various physical and chemical measures available for remedying copper-rich water bodies. However, these methods are time-consuming, costly, and not environmental-friendly (Qdais and Moussa, 2004;Wei et al, 2005;Fu and Wang, 2011;You et al, 2018;Chen et al, 2022a,b;Li et al, 2022;Wang et al, 2022a). In recent years, the microbial-induced carbonate precipitation (MICP) technology has attracted extensive attention as an alternative to traditional measures (Achal et al, 2012a;Chen and Achal, 2019;Ye et al, 2021;Xue et al, 2022a,b).…”

“…The use of carbonates aims to capsulize heavy metal ions by forming carbonate precipitation (termed immobilization of heavy metals hereafter), preventing their migration and diffusion (Achal et al, 2011;Achal et al, 2012b;Jiang and Soga, 2019;Chen and Achal, 2019;Schwantes-Cezario et al, 2020;Liu et al, 2021;Mujah et al, 2021;Zeng et al, 2021). Ali et al (2022) reported that strain B. diminuta isolated from soil could immobilize Cd 2+ and Zn 2+ in solution by coprecipitation. In addition, extracellular polymers (EPS) secreted by bacteria can provide nucleation sites and promote bacteria to immobilize heavy metal ions in solution (Chen et al, 2016;Casas et al, 2020;Qiao et al, 2021;Kim et al, 2021).…”

Catalyzing urea hydrolysis using two-step microbial-induced carbonate precipitation for copper immobilization: Perspective of pH regulation

et al. 2022

Microbial induced carbonate precipitation (MICP) has recently applied to immobilize heavy metals toward preventing their threats to public health and sustainable development of surrounding environments. However, for copper metallurgy activities higher copper ion concentrations cause the ureolytic bacteria to lose their activity, leading to some difficulty in forming carbonate precipitation for copper immobilization (referred to also as “biomineralization”). A series test tube experiments were conducted in the present work to investigate the effects of bacterial inoculation and pH conditions on the copper immobilization efficiency. The numerical simulations mainly aimed to compare with the experimental results to verify its applicability. The copper immobilization efficiency was attained through azurite precipitation under pH in a 4–6 range, while due to Cu2+ migration and diffusion, it reduced to zero under pH below 4. In case pH fell within a 7–9 range, the immobilization efficiency was attained via malachite precipitation. The copper-ammonia complexes formation reduced the immobilization efficiency to zero. The reductions were attributed either to the low degree of urea hydrolysis or to inappropriate pH conditions. The findings shed light on the necessity of securing the urease activity and modifying pH conditions using the two-step biomineralization approach while applying the MICP technology to remedy copper-rich water bodies.
