  • However, it is very important to point out that biofilms are an integral part of the natural environment and can also serve very beneficial purposes, such as in the treatment of drinking water, wastewater and detoxification of hazardous waste. (montana.edu)
  • Biofilms have been used successfully in water and wastewater treatment for over a century. (montana.edu)
  • Bioremediation hazardous pollutant treatment wastewater treatment and biofuel production are just a few biotechnological uses for biofilms [ 2 ]. (ijbpr.net)
Abiotic1
  • In numerous biotic and abiotic situations, pathogenic and saprophytic Leptospira have been observed to produce biofilms. (ijbpr.net)
Amoebae2
  • Extremely effective against biofilms and amoebae which are major risk factors in outbreaks of Legionnaires' disease. (accepta.com)
  • Single-celled organisms such as amoebae and ciliates move across the surface of biofilms 'grazing' on the bacteria nearest the surface. (waterhygienecentre.com)
Disperse1
  • The biofilm can then disperse, leading to a burst of infectivity. (kenyon.edu)
Disinfection1
  • Frequent cleanings can help keep biofilm at bay but without routine disinfection, it can still build up on the surface of your kitchen sink-which is why Tetro stresses the importance of doing both. (wellandgood.com)
Resistance3
  • S. aureus produces large biofilm formations that support its pathogenicity and confer protection and subsequently drug resistance ( 5 ). (frontiersin.org)
  • Antifungal resistance of biofilms results most probably from the conjunction of several mechanisms that act in a time-dependent manner. (pasteur.fr)
  • By far the most commonly known advantage for bacteria living in biofilm is the resistance to adverse conditions (e.g. temperature, pH and desiccation) and antimicrobial agents, such as water treatment chemicals and antibiotics. (waterhygienecentre.com)
Microbiologic2
  • Much of the work in the last 2 decades has relied on tools such as scanning electron microscopy (SEM) or standard microbiologic culture techniques for biofilm characterization. (cdc.gov)
  • The different structures and anatomy within the mouth afford various microenvironments that support different types of microbiologic organisms. (medscape.com)
Biocide1
  • MIOX electrochemical generators create your cooling tower water treatment biocide each day to keep your tower free of bacteria and biofilm. (miox.com)
