Special Issue Information

Dear Colleagues,

Microbial communities are responsible for energy and nutrient cycling, being vital for our planet’s sustainability. Microbes are directly involved in the dynamics of climate change through their impact on the destabilization, mineralization, and sequestration of organic matter. The facets of microbial diversity consist of morphological, structural, metabolic, ecological, or evolutionary diversity; however, the central question in microbial ecology—“Who eats what, where, and when?”—queries how the key player in the community is supposed to perform the most meaningful activity. To answer this, one major task is to identify the relationships between the composition of the microbial community and functional processes.

Here, we introduce this Special Issue, titled “State-of-the-Art Environmental Microbiology in China 2026”,which is the continuation of “State-of-the-Art Environmental Microbiology in China (2023–2024)”, https://www.mdpi.com/journal/microorganisms/special_issues/75S4KF6K98, and the Special Issue “State-of-the-Art Environmental Microbiology in China 2025”, https://www.mdpi.com/journal/microorganisms/special_issues/BW9CTAS1UJ. It will be devoted to topics focused on the study of microbial processes in the environment, microbial communities, and microbial interactions, including omics technologies and cross-disciplinary studies dedicated to basic and/or applied research in China.

Coral mucus serves as a crucial defensive barrier for corals, where the mucus microbes play a vital role in the coral’s resistance to external stresses. However, detailed knowledge of the effect of UV radiation on coral mucus microbiome is limited, particularly regarding the UV resistance mechanisms of coral mucus microbes. This study investigates changes in the mucus microbial community and possible UV-resistant mechanisms of the mucus microbiota of Porites sp. and Favites sp. under UV stress using high-throughput sequencing, UV-resistant microbial isolation, and RT-qPCR analysis. Compared to the control, UV stress alters microbial community structure by reducing microbial diversity, e.g., the relative abundance of Aquibacter, Agaribacter, and Oleibacter in coral Porites sp., and the Roseobacter clade CHAB_I_5 lineage, Roseivirga, and Nautella in coral Favites sp. increase under UV stress. Meanwhile, it is indicated that the Favites sp. mucus microbiome is much more sensitive than the Porites sp. mucus microbiome. A total of 428 microbial strains belonging to 5 phyla, 7 classes, 15 orders, 23 families, and 47 genera were isolated from these two coral mucus species, with Ruegeria and Rossellomorea as the most abundant cultured taxa. Pseudoalteromonas galatheae strain P12 and Limimaricola pyoseonensis strains P2 and P9 have been proven to exhibit higher UV resistance by enhanced expression of tyr, sod, gogat, and uvrC genes, indicating that the UV resistance of coral mucus bacteria involves complex molecular processes, including upregulation of antioxidant enzyme expression and enhancement of melanin and glutamic acid biosynthesis. These findings enhance our understanding of coral mucus microbial ecological functions, particularly highlighting the coral mucus microbial UV resistance strategy. Full article

Herbicides considered selective to rice are generally evaluated based on their direct crop safety and weed suppression effects, yet it remains unclear whether they may also trigger indirect or context-dependent effects on rice under rice–barnyardgrass co-cultivation. To address this question, we compared rice performance and associated microbial dynamics under six conditions: rice–barnyardgrass co-cultivation and rice monoculture, each treated with a water spray control or sublethal doses of propanil (Pro, 66.7 mg a.i. L−1) or cyhalofop-butyl (Cyh, 5.86 mg a.i. L−1). Barnyardgrass exhibited visible injury and stronger leaf-level oxidative stress responses, whereas rice displayed no discernible phytotoxic symptoms. Nevertheless, under co-cultivation, herbicide treatment significantly suppressed rice growth, with up to 17.8% lower root lengths and 24.8% lower shoot fresh weights, with reductions varying by herbicide and trait. By contrast, comparable suppression was not observed under herbicide exposure or co-cultivation alone, identifying this response as an emergent, context-dependent negative effect. Microbiota reassembly emerged as an early and stage-specific component of the herbicide-associated response under co-cultivation, with the most pronounced changes detected on day 5 and occurring primarily in bacterial communities. Moreover, bacterial community variation was negatively correlated with root length (ρ = −0.664), and urease activity declined under herbicide treatment. Together, these findings indicate that in paddy fields, herbicides act not only on individual plants but also as an external disturbance to the coupled rice–barnyardgrass system, for which microbiota reorganization represents a key component of the ecological response. Our results suggest that herbicide selectivity should be interpreted within a crop–weed–microbiome context, rather than being inferred solely from their direct crop safety and weed suppression effects.

Rapid industrialization, urbanization, resource exploitation, and energy use have caused global pollution and ecological degradation, hindering sustainable development. Functionally versatile microbes are eco-friendly resources for addressing environmental problems. Geobacter, a vital genus featuring outstanding extracellular electron transfer (EET), has drawn widespread research interest, with studies centered on EET mechanisms, microbial fuel cells, biogeochemical cycling and environmental bioremediation. Though valuable across energy, environmental and geoscience disciplines, a systematic bibliometric review of Geobacter research evolution is absent. This paper fills the gap via comprehensive bibliometric analysis of 2000–2026 Web of Science Core Collection papers covering Geobacter and the closely related genus Trichlorobacter, recently re-established as a standalone genus, focusing on bioremediation, dissimilatory Fe(III) reduction, microbial electrochemistry and biogeochemical cycles. This bibliometric profiling clarifies the evolving research frontiers in electroactive microbe-mediated environmental remediation and geochemical cycling, delivering refined scientific implications and actionable theoretical guidance for future ecological restoration and pollution remediation practices.
