Biofilm in industries

What is Biofilm? choose the best option

• Extracellular Polymeric Matrix

• Exopolysaccharide

• Microbial consortium attached to living or inert surface

• Biologically active matrix of microbial consortium and extracellular substances with solid surface

Biofilm formation starts with ...

• formation of huge amount of EPS / EPM that holds directly first

• attachment of planktonic / free-living microorganisms, that can produce EPS/EPM

• attachment of microorganisms without the presence of water

• intracellular enzymic hydrolysis of EPS produced by microorganisms

Biofilm formation progresses in the following pattern;

• Growth ---> Attachment ---> Colonization

• Attachment ---> colonization ---> growth

• Colonization ---> growth ---> attachment

• Growth ---> colonization ---> attachment

Biofilm formation are often reported in

• Dairy industries

• Flour mills

• Meat industries

• All of the above

Which of the following is not a problem, faced due to biofilm formation?

• Product loss

• increase in corrosion rate

• increase the fluid frictional rate

• increase in product formation
