This urgency highlights the need for sustainable alternatives to conventional control methods. Lactic acid bacteria (LAB), particularly Lactobacillus strains, have emerged as promising biocontrol agents due to their generally recognized as safe (GRAS) status and multifaceted antimicrobial properties. This review synthesizes current knowledge on the mechanisms of antiviral properties of Lactobacillus in aquaculture. The first line of defense involves direct virion inactivation through physicochemical interactions that sequester viral particles, combined with capsid destabilization by Lactobacillus metabolites. Subsequently, probiotics modulate host cell receptors to reduce viral attachment and entry. Finally, Lactobacillus strains stimulate systemic and mucosal antiviral immunity in aquatic hosts. By integrating these mechanisms, Lactobacillus establishes a multi-layered defense against viral intrusion. These mechanistic insights can guide the strategic application of Lactobacillus to enhance biosecurity and support the sustainable growth of the aquaculture industry.","PeriodicalId":73831,"journal":{"name":"Journal of microorganism control","volume":"31 3","pages":"73-79"},"PeriodicalIF":1.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148922080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Probiotics offers the advantages for disease control compared to other strategies and for some extremophiles, particularly halophilic bacteria, are gaining attention. This minireview examines the probiotic potential of halophilic bacteria as eco-friendly alternatives for disease control in marine fish farming. Halophilic bacteria, naturally adapted to high-salinity environments through specialized physiological mechanisms, offer distinct advantages over conventional probiotics that often fail to survive in marine conditions. Various studies have demonstrated that halophilic bacteria exhibit broad-spectrum antibacterial, antiviral, and antifungal activities while enhancing growth performance, digestive enzyme activity, and immune parameters in aquaculture species. Given the substantial contribution of marine fish to global food security and the specific challenges faced in their farming, halophilic bacteria particularly halophilic lactic acid bacteria with Generally Recognized as Safe (GRAS) status represent promising and sustainable alternatives for health management in aquaculture.","PeriodicalId":73831,"journal":{"name":"Journal of microorganism control","volume":"31 3","pages":"81-88"},"PeriodicalIF":1.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148922096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HP-HAW also showed moderate efficacy against Mycobacterium abscessus but limited activity against M. avium, M. kansasii, and spore-forming bacteria. Filamentous fungi such as Aspergillus niger were more resistant than the other fungal species tested, requiring longer exposure. Strong antiviral activity was observed against adenoviruses, influenza virus, norovirus, and others, although some enteroviruses (e.g., coxsackievirus A6 and B5) were resistant.

This study aimed to characterize endophytic fungi isolated from the roots of coffee plants cultivated in organic agroforestry systems and evaluate their potential as biocontrol agents against fungal pathogens, as well as their ability to promote plant growth. Biocontrol activity was assessed using in vitro dual-culture assays on potato dextrose agar, measuring the inhibition of pathogen growth. Plant growth promotion was evaluated by co-cultivating Arabidopsis thaliana seedlings with fungal isolates on Murashige and Skoog medium. Isolates were further subjected to both qualitative and quantitative biochemical characterization. A total of 18 endophytic fungal strains were identified and classified in five genera: Colletotrichum, Fusarium, Simplicillium, Lasiodiplodia and Trichoderma. Among these, ten Trichoderma isolates demonstrated strong antagonistic activity against selected fungal pathogens and significantly enhanced the growth of Arabidopsis seedlings in vitro. These beneficial effects were associated with the production of siderophores and indole-3-acetic acid, as well as the apparent nitrogen availability -- likely mediated through interactions with nitrogen-fixing bacteria.","PeriodicalId":73831,"journal":{"name":"Journal of microorganism control","volume":"31 3","pages":"105-113"},"PeriodicalIF":1.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148922104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following steam explosion pretreatment of rice straw, ethanol extraction was used to separate the lignin. The total phenolic content (TPC) in the ESL was 258 mg/g (gallic acid equivalent). Under UV-A irradiation, ESL exhibited bactericidal activity against Gram-positive and -negative bacteria at ≤10 mg TPC/L. Fluorescence experiments demonstrated significant adsorption of ESL to the cell surface of Staphylococcus aureus. Scanning electron microscopy revealed membrane deformation, producing many vesicles on the cell surface, when the ESL was activated by UV-A irradiation. These morphological changes were associated with an increase in membrane permeability, which elevated cell counts stained with propidium iodide to 51% and resulted in a 57% decrease in the intracellular ATP level. ESL exposed to UV-A light generated hydrogen peroxide. Addition of a scavenger of reactive oxygen species (ROS) or replacement of dissolved oxygen with argon gas in a bacterial suspension significantly suppressed the synergistic bactericidal activity of ESL and UV-A radiation, indicating that ROS are involved in the bactericidal mechanism. Organosolv lignin pretreated using steam explosion can be developed for antimicrobial application in combination with UV-A irradiation.","PeriodicalId":73831,"journal":{"name":"Journal of microorganism control","volume":"30 3","pages":"81-88"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detergents with or without antimicrobial agents partially removed the microorganism cells and more than 20% of cells survived even after washing and drying in almost all households. Bacterial flora analyses of washed fabrics revealed the presence of several typical genera: Enhydrobacter sp., Paracoccus sp., Sphingomonas sp., Roseomonas sp. and Kocuria sp. These results indicated that it is difficult to remove or eliminate microbial cells adhering to clothes and fabrics in home laundry. This report also indicated certain typical bacteria (adhesive type) seem to adhere or attach to fabrics, while bacteria (transient type) found in washing water have low adhesivity to fabrics. Therefore, understanding the adhesive properties of bacteria on fabrics may permit more efficient removal of microorganisms and reduction of malodors in home laundry.","PeriodicalId":73831,"journal":{"name":"Journal of microorganism control","volume":"30 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143733513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, 31 such samples were analyzed to identify microorganisms using MALDI-TOF MS with pretreatment using a membrane filtration protocol and a rapid BACpro II kit, compared to pretreatment with a rapid BACpro II kit alone. Reliable scores for E. coli and E. faecalis were obtained after inoculation of samples with 1.0×104 CFU/ml using the membrane filter with the rapid BACpro II kit, with approximately 10-fold higher sensitivity compared to rapid BACpro pretreatment alone. Among 31 bacteria-positive colonies in the samples, MALDI-TOF MS and membrane filtration (0.80 µm) with a rapid BACpro II kit was significantly more accurate compared to use of the kit alone (29 (82.9%) vs. 17 (48.6%) isolates identified, p<0.001).
