Enzymatic removal and disinfection of bacterial biofilms.
Model biofilms of Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas fluorescens, and Pseudomonas aeruginosa were made on steel and polypropylene substrata. Plaque-resembling biofilms of Streptococcus mutans, Actinomyces viscosus, and Fusobacterium nucleatum were made on saliva-coated hydroxyapatite. The activity of enzymes against bacterial cells in biofilm was measured by fluoresc...
متن کاملCleaning and disinfection practice in the meat industries of Europe.
The application and efficacy of cleaning and disinfection methods are reviewed, together with the relevant European and French legislation.

It is necessary to organise a team for washing, ...
متن کاملDirect measurement of chlorine penetration into biofilms during disinfection.
Transient chlorine concentration profiles were measured in biofilms during disinfection by use of a microelectrode developed for this investigation. The electrode had a tip diameter of ca. 10 microm and was sensitive to chlorine in the micromolar range. The biofilms contained Pseudomonas aeruginosa and Klebsiella pneumoniae. Chlorine concentrations measured in biofilms were typically only 20% o...

متن کاملOptimization of nitrogen and phosphorus removal from meat processing wastewaters using microalgal biofilms
Background: The conventional activated sludge processes are not able to completely treat the nitrogen and phosphorus compounds of meat processing wastewaters. Microalgal biofilm, which has the advantages of easiness and inexpensiveness, can be applied as a post-treatment method. Methods: The optimal levels of micronutrients and N/P ratio were aimed in the cultivation of Scenedesmus quadricauda...
