Invited review: Role of Bacillus licheniformis in the dairy industry—Friends or foes?

Journal of Dairy Science, Journal Year: 2024, Volume and Issue: 107(10), P. 7520 - 7532

Published: June 7, 2024

Bacillus licheniformis is one of the major spore-forming bacteria with great genotypic diversity in raw milk, dairy ingredients, final products, and found throughout processing continuum. Though being widely used as a probiotic strain, this species also serves potential risk industry based on its roles foodborne illness spoilage. Biofilm formation B. combined heat resistance spores, make it impossible to prevent presence products by traditional cleaning disinfection procedures. Despite extensive efforts identification from various samples, no reviews have been reported both hazard benefits spore-former. This review discusses prevalence milk commercial biofilm spoilage licheniformis, prevention methods. In addition, were summarized.

Olive Tree Twigs as an Attractive Green Source of Antioxidant and Antibiofilm Biomolecules

Processes, Journal Year: 2025, Volume and Issue: 13(2), P. 559 - 559

Biofilms represent complex three-dimensional microbial communities that can harbor strains highly resistant to antimicrobial agents. These structures, which form on both biotic and abiotic surfaces, are associated with food spoilage increased complications in hospitalized patients. Consequently, there is significant interest developing novel biofilm infection control strategies, particularly those focusing natural molecules dual antibiofilm properties. In this study, olive tree twigs from three varieties of Olea europea chemlal (CH), Azeradj (AZ), wild-type europaea sylvestris (W) were collected the Kabylia region Algeria. The samples underwent systematic extraction evaluated for their antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, properties via disk diffusion minimum inhibitory concentration (MIC), capabilities. Results demonstrated twig extracts exhibited substantial antibacterial potential. activity, measured through DPPH scavenging, showed IC50 values ranging 38.12 ± 1.52 µg/mL 148.7 1.23 µg/mL. When tested against six pathogenic bacterial strains, including ATCC reference milk isolates, MIC ranged 1.18 mg/mL 4.71 mg/mL. Notably, sub-inhibitory concentrations significantly reduced formation across most inhibition rates varying 21% 90.43%. effectiveness was dependent strain, variety, extract used. Statistical analysis confirmed significance these results (p < 0.05). Given antioxidant, antibacterial, extracts, they show promise further development as surface disinfectants potential applications safety control. Additional research warranted fully characterize mechanisms action optimize practical applications.

Supernatant of plant-associated bacteria potency against biofilms formed by foodborne pathogen and food spoilage bacteria

BMC Research Notes, Journal Year: 2024, Volume and Issue: 17(1)

Published: Nov. 14, 2024

Food products are often contaminated by pathogens and spoilage bacteria. Most of them can form biofilms, a community cells embedded in protective extracellular matrix layers resistant to harsh conditions, including antibiotics. Therefore, alternative antibiofilm agents required overcome biofilm formation. This study aims determine quantify the activity supernatants from plant-associated bacteria against biofilms foodborne pathogen food bacterium, namely Bacillus cereus subtilis. Plant-associated (PAB) have shown promising activities biofilm-forming previous studies. Thirteen PAB isolated Ternate, Indonesia were used this study. Supernatants subjected antimicrobial quorum quenching detection, both using well diffusion method. Four inhibited growth B. subtilis, but none affected cereus. Eight able disrupt sensing system an indicator wild-type Chromobacterium violaceum. Biofilm inhibition destruction quantified 96-well microplates.
