Silver ions, released by oxidation of silver nano-particles, strongly inhibit the growth of bacteria and other microorganisms. Mechanistically silver ions inhibit important cell structures and lead to cell death.<\/p>\n<p style=\"text-align: justify\">We study the formation of biofilm of Pseudomonas putida KT 2440 grown on the silver coating in a CDC Biofilm reactor.<\/p>\n<p style=\"text-align: justify\"><a href=\"https:\/\/pages.constructor.university\/ullrichmatthiasmicrobiology\/wp-content\/uploads\/sites\/39\/2015\/06\/image003_2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-147\" src=\"https:\/\/pages.constructor.university\/ullrichmatthiasmicrobiology\/wp-content\/uploads\/sites\/39\/2015\/06\/image003_2.jpg\" alt=\"image003_2\" width=\"114\" height=\"147\" \/><\/a><\/p>\n<p>Formation and structure of biofilm is studied by confocal laser scanning microscopy and scanning electron microscopy (SEM).<\/p>\n<p><a href=\"https:\/\/pages.constructor.university\/ullrichmatthiasmicrobiology\/wp-content\/uploads\/sites\/39\/2015\/06\/image002_1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-148\" src=\"https:\/\/pages.constructor.university\/ullrichmatthiasmicrobiology\/wp-content\/uploads\/sites\/39\/2015\/06\/image002_1-300x199.jpg\" alt=\"image002_1\" width=\"300\" height=\"199\" srcset=\"https:\/\/pages.constructor.university\/ullrichmatthiasmicrobiology\/wp-content\/uploads\/sites\/39\/2015\/06\/image002_1-300x199.jpg 300w, https:\/\/pages.constructor.university\/ullrichmatthiasmicrobiology\/wp-content\/uploads\/sites\/39\/2015\/06\/image002_1.jpg 303w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>3D reconstruction biofilm\t\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; Antimicrobial equipment of medicinal implants to prevent bacterial biofilm formation &nbsp; This project funded by BIG Bremen (Bremer Investitions-Gesellschaft mbH) in collaboration between Jacobs University Bremen and Bio-Gate AG.
