However, our understanding of BNP-producing microbes is limited, because many microbial populations remain uncultivated. Various approaches have been employed to explore the potential of these hidden microbes for new bioactive therapeutic compounds. Nevertheless, the possibility of discovering BNPs from microbial communities is largely cryptic due to their unculturable nature and the absence of triggers to activate the dormant Biosynthetic Gene Clusters (BGCs). Metagenome sequencing, followed by mining and characterization, is an effective approach for discovering new therapeutic BNPs. The inactive state of BGCs can be activated through the combinatorial interaction of different microbial communities within a common niche, overcoming programmable co-evolutionary stress and producing new BNPs.

The significant interactions and their importance form a dynamic interface between the roots of plants and the soil. Beneficial ones, especially plant growth-promoting bacteria (PGPB) and arbuscular mycorrhizal fungi (AMF), improve plant development and enhance stress resistance due to microbial secretions, exudates from roots, and edaphic factors. All these are very important in cultivating tea (Camellia sinensis (L.) O Kuntze) plants, boosting growth, yield, and leaf content of amino acids, proteins, caffeine, and polyphenols. Yet, the molecular mechanisms of such interactions necessitate high-end technologies like genome editing and proteomics to fine-tune rhizosphere dynamics for greater plant health and productivity. The root exudates, rich in nutrients, serve as a source of food for the soil microbes while facilitating communication and colonisation by beneficial organisms, such as AMF and bacteria, thus significantly impacting the performance of a tea plant. High nitrogen fertilisers are readily applied in tea farming, although environmental risks include soil acidification and increased emissions of nitrous oxide (N<sub>2</sub>O), a potent greenhouse gas. Understanding and manipulating plant root-soil microbe interactions are critical for developing sustainable farming systems that enhance productivity without causing environmental damage. This review describes the mechanisms by which beneficial microbes function in the rhizosphere, strategies for modifying root exudates to improve tea production, and the tea microbiome's underexplored potential in contributing towards sustainability. This review thus emerges as one that presents knowledge gaps and possible future directions in tea microbiome science predicated on the amelioration of tea farming by enhancing productivity and ensuring environmental sustainability.</p>","PeriodicalId":11360,"journal":{"name":"Current Microbiology","volume":"82 6","pages":"257"},"PeriodicalIF":2.3,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143958914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the critical consequences of CMV infection in the brain, little is known about the mechanisms of neuropathogenesis responsible for malformations and dysfunction in the central nervous system. Some reports point out the infection of neural precursor cells (NPCs) as a key element in this process; these cells show the greatest susceptibility to CMV in the developing brain. In order to further characterize how CMV perturbs NPCs properties, we investigated the effect of human CMV strain AD169 in the neural stem cell cycle, viability, phenotype, and function of hNS-1 cells (immortalized cell line of human fetal brain). Notably, both infected and non-infected cells undergo apoptosis, with CMV infection not inducing a higher rate of apoptosis compared to non-infected cells. Upon infection and induction of differentiation in hNS-1 cells, the transcriptional expression of the NMDA receptor and the astrocyte marker GFAP is significantly reduced. Immunofluorescence assays corroborate the inhibition of astrocyte differentiation by CMV infection, while differentiation to neurons remains unaffected. Furthermore, our study demonstrates that CMV-infected hNS-1 cells exhibit impaired responses to multiple agonists after differentiation, including purinergic and GABAergic neurotransmission. These observations shed light on the previously understudied aspect of human CMV's influence on NPCs' function, providing valuable insights into the intricate interplay between CMV and neural development.</p>","PeriodicalId":11360,"journal":{"name":"Current Microbiology","volume":"82 6","pages":"256"},"PeriodicalIF":2.3,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143971872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, irradiated P. aeruginosa demonstrated a modest increase in the production of both biofilms and biosurfactants.

The incorporation of Nanomagnet-Porphyrin Hybrid (NMPH) based aPDI illustrates notable microbial inactivation and innovatively introduces prospects of achieving affordable and ecologically beneficial disinfection within wastewaters since they can be recycled and reused. Furthermore the added advantage of NMPHs based aPDI lies in the generation of a high quantum yield of cytotoxic <sup>1</sup>O<sub>2</sub> due to a strong visible absorption ascribed to π-π* electronic transitions within the porphyrins. These properties are largely ascribed to the high coefficient of light absorption in a broad wavelength range allowing them to generate reactive oxygen species through a spin-forbidden intersystem crossing mechanism allowing them to demonstrate express disinfection of harmful pathogens. This review addresses the high inactivation profiles of NMPH based aPDI, its low operating costs and reusability as the potential of establishing NMPH based aPDI in nanotechnology wastewater remediation and microbial disinfection applications. The authors believe that this systematic review can stimulate new researchers and assist in the future development of this important field of research, especially when it comes to the aquatic environment and natural water resources and given the adequate attention this method can aid globally but more so within emerging economies to ensure potable water is delivered to all people.</p>","PeriodicalId":11360,"journal":{"name":"Current Microbiology","volume":"82 6","pages":"249"},"PeriodicalIF":2.3,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12008068/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143969685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
