6) In a report to the New York Ophthalmological Society in 1912, Knapp noted that some patients who underwent cataract surgery later manifested clinical signs of dystrophia epithelialis with stromal and epithelial oedema, as described by Fuchs; (7) this is now known as pseudophakic bullous keratopathy (PBK), which is a complication of cataract ...
A biofilm is any group of microorganisms in which cells stick to each other and often also to a surface. These adherent cells become embedded within a slimy extracellular matrix that is composed of extracellular polymeric substances (EPS).
Problems caused by biofilms. BÃ¸rge K. Mortensen. Bactoforce International A/S. Biofilms will form on critical locations in processing plants in the food and beverage. industries, where nutrients are available and where cleaning and disinfection are. inadequate. Formation of biofilms can lead to a number of problems such as product. spoilage, food safety problems, and loss of production efficiency. Countermeasures against biofilms are therefore in focus in good manufacturing practice. A general problem caused by biofilms is that some cellular by-products accelerate corrosion of stainless steel. Other problems are that biofilm formation in heat exchangers reduces the fluid flow and the heat transfer; and in membrane filtration units, biofilm will block membrane pores, which decreases the flux of permeate,
