“…Moreover, monitoring the diversity and populations of these protective bacterial communities may serve as a prognostic tool to assess disease progression or response to treatment. Lastly, understanding the mechanisms by which microbial communities influence CRC can help in developing novel therapeutics that target the microbiota to prevent or treat the disease [8].…”

Our investigation provides a critical examination of the gut microbiota's role in colorectal cancer (CRC), employing state-of-the-art high-throughput 16S rRNA gene sequencing to uncover the distinct microbial communities associated with CRC. The study reveals significant dysbiosis in CRC patients, characterized by a decrease in microbial diversity and an enrichment of pathogenic bacteria. These microbiological alterations present as unique signatures, distinguishing CRC patients from healthy individuals with notable clarity. Highlighting their potential as non-invasive biomarkers, these microbial signatures offer a new avenue for early CRC detection, which is pivotal for improving patient outcomes. Additionally, the study's findings point toward the therapeutic potential of microbiota modulation, suggesting that targeting these microbial discrepancies could become a novel strategy in CRC management. The implications of this research are far-reaching, setting a foundation for future explorations into the microbiota's diagnostic and therapeutic applications in CRC.

“…MND1 and Nitrospira in the NRI treatment and Sphingomonas in the RI treatment most effectively explained the variations between bamboo in rhizosphere and non-rhizosphere soils with intercropping and monocropping. These bacteria may play a role in the N cycle [53]: MND1 and Nitrospira function as nitrifiers, while the N-fixing bacteria Sphingomonas can enhance the production of NO 3− -N. In addition, they have also been proven to have strong tolerance to heavy metals [54][55][56]: Nitrospira exhibits Cd tolerance through the overproduction of electron-transporting cytochrome c-like proteins, while Sphingomonas, a plant growth-promoting rhizobacterium, enhances plant productivity by hormone production. This suggests that after S. plumbizincicola was planted, bacteria involved in heavy metal remediation and nutrient cycling were enriched in the bamboo forest.…”

Heavy metal pollution in soil is a major global issue, and one effective method for addressing it is phytoremediation through bamboo planting. Nevertheless, there is a notable gap in our knowledge as no studies have explored the characteristics of soil organic matter (SOM) and the bacterial communities in bamboo forests during the remediation process. To bridge this knowledge gap, we conducted research to investigate the impact of different bamboo planting patterns on the SOM characteristics and microbial communities in soils contaminated with heavy metals. The contents of SOM and dissolved organic matter (DOM) in rhizosphere and non-rhizosphere soils differed significantly between monocropping and intercropping systems, with DOM accounting for only 1.7%–2.5% of SOM. Fourier transform infrared spectra showed that the contents of SOM polysaccharides C-O, carbonate C-O, aliphatic methyl, and methylene increased, while the aromatic C=C abundance decreased in the intercropping rhizosphere soil. The differences between bamboo cultivation patterns in the rhizosphere and non-rhizosphere soils were elucidated using the biomarkers, including MND1 and Nitrospira (non-rhizosphere), and Sphingomonas (rhizosphere). Heavy metals, DOM, SOM, and refined organic functional groups, especially C-O in polysaccharides and symmetric carboxylate, were the determining factors of soil bacterial communities. Compared to monocropping, intercropping increased the accumulation of Zn and Cd in bamboo shoots by 35% and 40%, respectively, and hence, intercropping soil, with a low toxicity, was suitable for bamboo shoot sprouting. Intercropping can alter the characteristics of SOM and bacterial communities and plays a vital role in phytoremediation and shoot growth in bamboo forests. Future studies on soil carbon dynamics and nutrient status during heavy metal remediation will improve our knowledge of soil transformation and its impact on soil ecosystem health and productivity.
