| emergence of leuconostoc mesenteroides as a causative agent of oozing in carrots stored under non-ventilated conditions. | long-term storage and transport of post-harvest carrots (daucus carota l.) require a low-temperature, high-relative-humidity environment, usually with low ventilation. following long-term storage, a slimy exudate (oozing) often appears on the carrots, leading to severe spoilage. we characterized the environmental conditions leading to these symptoms and identified the causative agent. simulation of non-ventilated storage conditions revealed accumulation of co2 (to 80%) and ethanol (to 1000 ppm); ... | 2017 | 28834204 |
| clinical and microbiological characteristics of pantoea agglomerans infection in children. | pantoea agglomerans is an environmental gram-negative bacterium that rarely is responsible for the infections in humans but it is often a causative factor of a number of occupational diseases. this study evaluated the clinical and microbiological characteristics and pathogenicity of p. agglomerans in children. we retrospectively reviewed microbiological test results for all children (1 month old to 18 years old) who were admitted to our pediatric hospital between january 2000 to june 2015 and ha ... | 2017 | 28780309 |
| aerobiological stability of different species of gram-negative bacteria, including well-known biothreat simulants, in single-cell particles and cell clusters of different composition. | the ability to perform controlled experiments with bioaerosols is a fundamental enabler of many bioaerosol research disciplines. a practical alternative to using hazardous biothreat agents, e.g. for detection equipment development and testing, involves using appropriate model organisms (simulants). several species of gram-negative bacteria have been used or proposed as biothreat simulants. the appropriateness of different bacterial genera, species, and strains as simulants is however still debat ... | 2017 | 28687646 |

| in vitro investigation of crosstalk between fatty acid and polyketide synthases in the andrimid biosynthetic assembly line. | andrimid (adm) synthase, which belongs to the type ii system of enzymes, produces adm in pantoea agglomerans. the adm biosynthetic gene cluster lacks canonical acyltransferases (ats) to load the malonyl group to acyl carrier proteins (acps), thus suggesting that a malonyl-coa acp transacylase (mcat) from the fatty acid synthase (fas) complex provides the essential at activity in adm biosynthesis. here we report that an mcat is essential for catalysis of the transacylation of malonate from malony ... | 2016 | 27598417 |
