“…Many microbial species can play a role in DDT degradation ( Table 1 ). White rot fungi species were able to degrade seventy (70) and thirty (30) percent of DDT, respectively, within twenty-one (21) days of incubation in a low-nitrogen medium [ 57 , 58 ]. Microbial DDT degradation" primarily refers to three processes: In the first, the original parent pesticide chemical is converted into soluble and non-toxic metabolites through reduction, hydrolysis, or oxidation [ 59 , 60 ].…”

“…Few studies have been conducted on the microbial mineralization of organic pollutants, but the minerals produced by microorganisms can effectively plug pores and reduce permeability [132], and the diffusion of organic pollutants can be effectively controlled through microbial mineralization [133]. It also provides sufficient time and safety for other methods (such as biodegradation [134][135][136]) to be used to remove organic pollutants [137]. To date, there has been little research on this, but many scholars' research results for reducing permeability show that it has good application prospects.…”

Microbial-induced mineralization is a process in which metal ions in the environment are processed by microorganisms, forming deposits of crystals with cementing and void-filling functions. Cementing crystals can fix metal ions, reduce permeability, improve soil strength, and play a positive role in soil remediation and pollution control. This paper first introduces the principle of microbial-induced mineralization and analyzes its mechanism of action in the treatment of soil organic and inorganic pollutants. Then, the mineralization principle of different types of mineralized bacteria in soil (fungal metabolism involving organic acid complexation and metabolic urease catalysis, sulfur oxidation by sulfur-oxidizing bacteria, dissimilatory sulfate reduction by sulfate-reducing bacteria, ammonification by ammoniating bacteria, reverse digestion by denitrifying bacteria, urease catalysis by urease-producing bacteria, acetic acid fermentation by methanogenic bacteria, and H2/CO2 reduction) is elaborated, the influencing factors in the treatment of soil pollutants by mineralization technology in practical application are analyzed, and the current status of mineralization treatment for different types of pollutants is summarized. Finally, the future prospects of soil pollutant treatment are outlined to promote research into microbial-induced mineralization technology for the treatment of soil pollutants.

In dry deciduous tropical forests, both seasons (winter and summer) offer habitats that are essential ecologically. How these seasonal changes affect soil properties and microbial communities is not yet fully understood. This study aimed to investigate the influence of seasonal fluctuations on soil characteristics and microbial populations. The soil moisture content dramatically increases in the summer. However, the soil pH only gradually shifts from acidic to slightly neutral. During the summer, electrical conductivity (EC) values range from 0.62 to 1.03 ds m-1, in contrast to their decline in the winter. The levels of soil macronutrients and micronutrients increase during the summer, as does the quantity of soil organic carbon (SOC). A two-way ANOVA analysis reveals limited impacts of seasonal fluctuations and specific geographic locations on the amounts of accessible nitrogen (N) and phosphorus (P). Moreover, dehydrogenase, nitrate reductase, and urease activities rise in the summer, while chitinase, protease, and acid phosphatase activities are more pronounced in the winter. The soil microbes were identified in both seasons through 16S rRNA and ITS (Internal Transcribed Spacer) gene sequencing. Results revealed Proteobacteria and Ascomycota as predominant bacterial and fungal phyla. However, Bacillus, Pseudomonas, and Burkholderia are dominant bacterial genera, and Aspergillus, Alternaria, and Trichoderma are dominant fungal genera in the forest soil samples. Dominant bacterial and fungal genera may play a role in essential ecosystem services such as soil health management and nutrient cycling. In both seasons, clear relationships exist between soil properties, including pH, moisture, iron (Fe), zinc (Zn), and microbial diversity. Enzymatic activities and microbial shift relate positively with soil parameters. This study highlights robust soil-microbial interactions that persist mainly in the top layers of tropical dry deciduous forests in the summer and winter seasons. It provides insights into the responses of soil-microbial communities to seasonal changes, advancing our understanding of ecosystem dynamics and biodiversity preservation.
