DESIGNING OF CURRENT INDUCED BIOFILM INHIBITORY DEVICE FOR CHECKING THE GROWTH OF PSEUDOMONAS AERUGINOSA BIOFILM

D. JANSI RANI AND V. KARTHIK

Abstract

Biofilms are the assemblage of microbial cells that are irreversibly associated with a surface which is not removed by gentle rinsing. The present study was undertaken to disturb the complex association of Pseudomonas aeruginosa biofilm in materials like PVC, iron and stainless steel by inducing current through a device. The disintegration of Pseudomonas aeruginosa was done by applying the low intensity current at constant time intervals. The current induced produces pores on the EPS layer. The treatment of these materials involves the application of current along with antibiotics. The antibiotics enter through the pores formed in the EPS layer of microorganism. The reduction in the level of microbial colony due to the action of different antibiotics was determined by the spread plate technique.
