By detailing factors such as temperature, pH, and water activity, it examines how these elements influence transitions between vegetative growth, sporulation, and germination, as well as the quality of the spores produced, particularly their resistance and germination ability. The review also addresses the heterogeneity observed in the spore-forming bacteria life cycle, particularly variation in germination and outgrowth responses, as well as phenomena such as cannibalism, competence, and biofilm formation. It highlights the significance of these factors for understanding the persistence and dispersal of spores across different environments. The implications of these mechanisms are particularly relevant for the food industry, where effective management of contamination by spores is critical for controlling food spoilage and safety. It also has important implications for biotechnology. A better understanding of how environmental conditions influence spore properties can help optimize the production of spores with specific resistance or germination traits suited to their intended applications.","PeriodicalId":73831,"journal":{"name":"Journal of microorganism control","volume":"31 1","pages":"1-24"},"PeriodicalIF":1.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147464314","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}

With the global incidence of Acanthamoeba infections increasing and no specific treatment currently available, research into novel anti-Acanthamoeba agents remains essential. Similarly, cancer cases are also rising worldwide, and effective treatments continue to be a major challenge. In this context, the present study aimed to investigate the anti-Acanthamoeba and anticancer activities of marine Actinomycetes isolated from Türkiye. Fifteen Actinomycetes cell-free supernatants were prepared and used in this study. To evaluate anti-Acanthamoeba effects, Acanthamoeba strains isolated from swimming pools in our previous research as well as standard Acanthamoeba castellanii (A. castellanii ) strains, were employed. The MCF-7 breast cancer cell line and the HaCaT human keratinocyte cell line served as models for assessing cytotoxic activity. Three Actinomycetes supernatants (20%) demonstrated strong inhibitory activity against all tested Acanthamoeba strains. MCF-7 cells were found to be more sensitive to one supernatant across all tested dilutions. These findings suggest that marine-derived Actinomycetes, are promising candidates for Acanthamoeba trophozoites. Moreover, the results may guide future research on cytotoxic bacterial metabolites produced by marine Actinomycetes.","PeriodicalId":73831,"journal":{"name":"Journal of microorganism control","volume":"31 2","pages":"55-61"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148221224","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, we investigated the combined effect of hydrostatic pressure processing (HPP) and the addition of a food emulsifier (sucrose fatty acid ester; SE) on two bacterial spores (Bacillus spizizeni and Alicyclobacillus acidoterrestris）. The results demonstrated that supplementing HPP at 50 MPa with SE significantly reduced the heat resistance of both spores. In particular, A. acidoterrestris spores were more sensitive to treatment than the B. spizizenii spores. HPP combined with SE resulted in a 4 log reduction in A. acidoterrestris spores, whereas a 2 log reduction was observed for B. spizizenii spores. Additionally, heat treatment following HPP combined with SE further inactivated B. spizizenii spores by 0.5 log. To evaluate practical applications in the food industry, the effect of the SE-HPP combination in the presence of glucose, a representative nutrient component, was also assessed. The findings indicated that the heat resistance of A. acidoterrestris spores was reduced, with viable spore counts falling below the detection limit (less than 10 CFU/mL）. These results suggest that this approach may enhance the efficiency of HPP in bacterial spore control for food processing applications.","PeriodicalId":73831,"journal":{"name":"Journal of microorganism control","volume":"31 1","pages":"39-43"},"PeriodicalIF":1.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147464351","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, live and dead fungi present on 12 windows were examined during different seasons. Cladosporium halotolerans was predominantly detected, followed by Aureobasidium pullulans, both of which are common dark fungi. The total fungal including both live and dead fungi was quantified by real-time PCR. A significant correlation was noted between the counts of live and total fungi on different beads. The average live fungal count on beads sharply decreased under severe conditions, such as exposure to drought and heat, from February-October. Comparatively, the number of dead fungi gradually decreased as fragments remained attached to beads. Notably, dead cell counts were higher than those of live cells, with dead fungi contributing to dirt more than live fungi did. Therefore, common fungicidal treatment is ineffective for cleaning beads. The degree of dirt on beads likely depends on the melanin levels in dead fungal cells (predominantly C. halotolerans). Despite the dead cell counts of C. halotolerans decreasing to one-quarter of the initial values from winter to autumn, dirt levels on beads remained unchanged.","PeriodicalId":73831,"journal":{"name":"Journal of microorganism control","volume":"31 3","pages":"115-122"},"PeriodicalIF":1.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148922083","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}

One of the strategies is by utilizing bioactive compound from natural product. However, the current method of extraction requires a huge amount of solvent and cause detrimental to the end product. Thus, this lead to extraction strategy using supercritical carbon dioxide (SC-CO2). This minireview explores the application of SC-CO2 extraction as a green technology for disease management in aquaculture. SC-CO2 operates as a clean, selective solvent, efficiently isolating high-purity bioactive compounds from plant, algal, and fishery by-products without toxic solvent residues. Unlike conventional extraction methods, SC-CO2 preserves thermolabile antimicrobial compounds, yielding extracts with enhanced bioactivity against aquatic pathogens. By providing effective, natural alternatives to antibiotics, SC-CO2 technology directly contributes to disease control in aquaculture. The integration of SC-CO2-derived natural products represents a transformative strategy for sustainable microbial control while aligning with the principles of environmental safety and food security.","PeriodicalId":73831,"journal":{"name":"Journal of microorganism control","volume":"31 1","pages":"25-33"},"PeriodicalIF":1.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147464383","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}

A rapid and standardized quantification method for evaluating initial contamination levels of LM in food remains to be established. This study aimed to develop a rapid quantification method to monitor LM contamination in food handling facilities. A regression equation was developed to determine the concentrations of LM cells before and after enrichment. Regression equations developed to estimate LM cell concentrations in food samples (ground poultry and green salad) were evaluated. The concentrations of LM cells in ground poultry and green salad before enrichment were 2.44 and 2.92 log10 CFU/g, respectively, and the concentrations obtained using a rapid qPCR-based detection and quantification method were 2.05 and 3.27 log10 CFU/g, respectively. The proposed method can semi-quantitatively estimate LM contamination at approximately 102 CFU/g of food, which is the maximum allowable level of LM contamination in foods.

Zeta potential analysis and spore quantification were performed to explore the mechanism of action of LAS. LAS displayed pronounced sporicidal activity only under both acidic conditions (pH ≤5) and elevated temperature (≥50°C). In the presence of 1 mM LAS in 10 mM citric acid (pH 2.7) at 70°C, B. subtilis spore counts were reduced by >5.7 log10 colony forming units/mL within 5 min.
