Toxins, Journal Year: 2024, Volume and Issue: 16(11), P. 478 - 478

Published: Nov. 4, 2024

Mycotoxins are toxic secondary metabolites produced by various types of fungi that known to contaminate food products; their presence in the chain poses significant risks human and animal health leads enormous economic losses feed industry worldwide. Ensuring safety quality detoxifying mycotoxin is therefore paramount importance. Several procedures control fungal toxins have been extensively investigated, such as preventive measures, physical chemical methods, biological strategies. In recent years, microbial degradation mycotoxins has attracted much attention due its reliability, efficiency, cost-effectiveness. Notably, bacterial species from Bacillus genus emerged promising candidates for decontamination owing diverse metabolic capabilities resilience harsh environmental conditions. This review manuscript aims provide a summary studies on biodegradation bacteria, thereby illustrating potential applications development mycotoxin-degrading products.

Genome and Transcriptome Analysis to Elucidate the Biocontrol Mechanism of Bacillus amyloliquefaciens XJ5 against Alternaria solani

Microorganisms, Journal Year: 2023, Volume and Issue: 11(8), P. 2055 - 2055

Published: Aug. 10, 2023

Early blight, caused by Alternaria solani, is an important disease affecting tomatoes. Biological control offers environmentally friendly approach to controlling pathogens. Herein, we identified a B. amyloliquefaciens strain XJ5 and investigated its biocontrol mechanism against A. solani. solani growth was significantly inhibited XJ5, with the inhibition rate of cell-free culture supernatants reaching 82.3%. Furthermore, crude protein extracts conidia germination altered mycelial morphology To uncover potential analyzed genome sequence transcriptome. The comprised 4.16 Mb circular chromosome two plasmids. A total 13 biosynthetic gene clusters 127 genes encoding hydrolases were identified, suggestive ability secrete antagonistic secondary metabolites hydrolases. Transcript analysis revealed 174 differentially expressed on exposing extracts. expression related chitin mannose synthesis downregulated, indicating that may impact in Overall, these findings enhance our understanding interactions between phytopathogens pave way for agricultural application this promising agent.

Decoding gene expression dynamics in planktonic and biofilm cells of Streptococcus mutans: regulation and role of mutanofactin genes in biofilm formation

Frontiers in Oral Health, Journal Year: 2025, Volume and Issue: 6

Published: Jan. 17, 2025

Dental caries is the most prevalent chronic infectious disease globally, with Streptococcus mutans recognized as a primary causative agent due to its acidogenicity and robust biofilm-forming ability. In S. biofilm formation, role of autoinducers has been extensively studied, while influence other small molecules remains largely unexplored. Mutanofactins, class polyketide/non-ribosomal lipopeptide secondary metabolites, are emerging potential modulators development. Transcriptomic analysis was conducted examine gene expression patterns in NMT4863 across distinct growth phases lifestyles, aiming identify metabolic factors influencing formation. profiles were compared between cells early-, mid-, late-exponential-, stationary phase, well planktonic cells. Differentially expressed genes identified, pathway analyses revealed significant alterations key regulatory pathways. Specifically, biosynthetic mutanofactin cluster analyzed via quantitative real-time polymerase chain reaction. Several operons differentially tested phases, 1,095 showing differential stationary-phase, Pathway changes ascorbate metabolism, carbohydrate utilization transport systems, lipoic acid bacterial toxin pathways, two-component metabolite biosynthesis.
