Bacillus species present a major concern in the dairy industry as they can form biofilms pipelines and on surfaces of equipment machinery used entire line production. These represent continuous hygienic problem lead to serious economic losses due food spoilage impairment. Biofilm formation by subtilis is apparently dependent LuxS quorum sensing (QS) Autoinducer-2 (AI-2). However, link between environmental cues AI-2 induced biofilm remains largely unknown. The aim this study investigate role...
Pathogenic fungi cause major postharvest losses. During storage and ripening, fruit becomes highly susceptible to that disease. Fungicides are effective treatments limit However, due increased public concern for their possible side effects, there is a need develop new strategies control fungal pathogens. Botrytis cinerea, common pathogen, was shown uptake small double-stranded RNA (dsRNA) molecules from the host plant. Such dsRNA can regulate gene expression through interference system. This...
Stem-end rot (SER) is a serious postharvest disease of mango fruit grown in semi-dry area. Pathogenic and non-pathogenic microorganisms endophytically colonize stem-end. As ripens, some pathogenic fungi switch from endophytic colonization to necrotrophic stage cause SER. Various pre/post-treatments may alter the stem-end community modify SER incidence. This study investigates effects harvesting with or without short on antifungal antioxidant activities, microbiome, during storage. Our...
Biofilm is commonly defined as accumulation of microbes, embedded in a self-secreted extra-cellular matrix, on solid surfaces or liquid interfaces. In this study, we analyze several aspects Bacillus subtilis biofilm formation using tools from the field image processing. Specifically, characterize growth kinetics and morphological features B. colony type compare these colonies grown two different types media. Additionally, propose model for assessing complexity across conditions. GFP-labeled...
A limited number of studies have examined how drying conditions affect the cannabinoid and terpene content in cannabis inflorescences. In present study, we evaluated potential controlled atmosphere chambers for medicinal inflorescence. Controlled were found to reduce curing time by at least 60% compared traditional methods, while preserving volatile content. On other hand, inflorescences subjected highly infested Alternaria alternata also revealed low infestation Botrytis cinerea. high-THC...
Biofilms are commonly defined as accumulations of microbes, embedded in a self-secreted, polysaccharide-rich extra-cellular matrix. This study aimed to characterize specific morphological changes that occur Bacillus subtilis biofilms under nutrient-limiting growth conditions. Under varying levels nutrient depletion, colony-type were found exhibit different rates spatial expansion and green fluorescent protein production. Specifically, grown on media with decreased lysogeny broth content...
Many bacteria in biofilm surround themselves by an extracellular matrix composed mainly of polysaccharide (EP), proteins such as amyloid-like fibers (ALF) and nucleic acids. While the importance EP attachment acceleration a number different bacterial species is well established, contribution ALF to multispecies remains unknown. The study presented here aimed investigate role TasA, precursor for ALF, cell-cell interactions dual-species biofilms Bacillus subtilis Streptococcus mutans....
Lasiodiplodia theobromae attacks over 500 plant species and is an important pathogen of tropical subtropical fruit. Due to global warming climate change, the incidence disease associated with L. rising. Virulence tests performed on avocado mango branches fruit showed a large diversity virulence different isolates. Genome sequencing was for two isolates, representing more virulent (Avo62) less-virulent (Man7) strains, determine cause their variation. Comparative genomics, including...
Bacillus subtilis is a Gram-positive probiotic bacterium that successfully colonises plant roots due to its ability utilise various sugars. The vast potential of B. has been recently demonstrated in numerous host organisms under different environmental conditions. We examined the against pathogenic Streptococcus mutans, which involved oral disorders robust biofilm-forming capability. cells attenuated biofilm formation by S. mutans during their dual growth presence sugar alcohols....
Milk is believed to be a relatively "caries-safe" food. This belief relies on the fact that caseins, which constitute around 80% of milk's protein content, were found inhibit adhesion Streptococcusmutans enamel and, therefore, decrease biofilm formation. While S.mutans considered leading cause dental disorders, Bacillus subtilis non-pathogenic foodborne bacterium, frequently contaminating milk and its products. study aimed investigate effects dairy-associated bacteria such as B. formation by...
Fungal pathogens are a central cause of the high wastage rates harvested fruit and vegetables. Seaweeds from genus Ulva fast-growing edible green macroalgae whose species can be found on shore every continent, therefore present resource that utilized global scale. In this study, we application ulvan extract, sulfated polysaccharide extracted rigida (1000 mg/L), elicited table grapes defense reduced incidence decay area Botrytis cinerea by 43% 41%, respectively. addition, compared to control...
The human skin is a lush microbial habitat which occupied by wide array of microorganisms. Among the most common inhabitants are Staphylococcus spp., namely epidermidis and, in ≈20% healthy individuals, aureus. Both bacteria have been associated with cutaneous maladies, where they mostly arrange biofilm, thus achieving improved surface adhesion and stability. Moreover, our constantly exposed to numerous oxidative environmental stressors, such as UV-irradiation. Thus, cells equipped an...
The global food security crisis is emphasized by the alarming amount of waste, where about one-third world’s production, roughly 1.3 billion metric tons, lost annually. Pathogens, such as Botrytis cinerea, contribute significantly to this loss attacking stored agricultural produce. These attacks typically start when pathogens infiltrate small fruit wounds, remain dormant, and then switch an aggressive necrotrophic stage upon ripening, causing significant postharvest losses. In response...
