Structure of deposits formed by drying of droplets contaminated with Bacillus spores determines their resistance to rinsing and cleaning

The formation of deposits by evaporation droplets contaminated Bacillus spores was investigated, focusing on the role spore and material properties. Droplets containing hydrophilic to hydrophobic were deposited materials (stainless steels, polypropylene, glass). presence within droplets, as well hydrophobicity plays a major in kinetics droplet shape during drying while pattern dried deposit affected both resistance detachment different then investigated. After single rinsing procedure, very high adherent observed (up 90% residual spores). Bs PY79 least resistant removal, differences between not pronounced. ease cleaning much greater. still ones, 3–100 times more effective glass than other materials. These results highlight predominant hydrophilic/hydrophobic properties particles structure their further procedures.
