Adhesion of a Pseudomonas putida strain isolated from a paper machine to cellulose fibres

摘要: The adhesion to cellulose fibres of a strain Pseudomonas putida isolated from paper machine was studied under different environmental conditions. physicochemical properties both P. cells and were also determined better understand the phenomenon. Adhesion rapid (1 min) increased with time, cell concentration temperature (from 25 40 degrees C), indicating that bacterial is essentially governed by process. surface negatively charged, as shown electrophoretic mobility measurements, hydrophilic due strong electron-donor character, microbial solvents method. Cellulose be contact angle measurements using capillary rise These results suggest importance Lewis acid-base interactions in In various ionic solutions (NaCl, KCl, CaCl(2) MgCl(2)), increasing strength up 10-100 mM, that, at low strength, electrostatic involved An increase C/N ratio growth medium 5 90) decreased but this could not related changes properties, suggesting other factors may involved. practice, temperature, nitrogen must taken into consideration reduce contamination industry.
