“…2). It has been earlier observed that an increase in conductivity is proportional to the corresponding decrease in cells in a suspension thus con rming the decrease in suspended bacterial cells (Harris and Patty, 1949).Furthermore, honeytrap indicated that the strip has a percent reduction value of 96% and a log reduction equivalent to 1.6.…”

This paper introduces a novel prototype for the removal of Pseudomonas from water samples. Bacterial cells have the tendency to get attracted towards specific chemicals (chemotaxis); a ‘honeytrap’ strip was conceptualized by integrating a combination of serine, pseudomonas specific chemo-attractant and honey to attract and inhibit the bacteria in situ. Honey, a natural antimicrobial agent, has garnered attention in its effective inhibitory role in Pseudomonal biofilms and wound infections. Dipping serine side of the strip attracted bacteria towards honeytrap, wherebythe porous nature of the strip facilitated the ‘trapping’ and subsequent diffusion of the bacterial cells towards honey-adsorbed end of the strip. This ‘honeytrap’ reportedly leads to the targeted elimination of Pseudomonas, hence facilitating its removal. The percentage efficacy of this ‘honeytrap’ device is 96% with a log reduction equivalent to 1.6 within a time frame of 2 hours. Pseudomonas aeruginosa, although, not a natural contaminant of potable water, enters circulation due to improperly maintained plumbing fixtures and storage facilities. Honeytrap strip is an easy to use, biodegradable and cost effective sustainable solution, and thus a scaled up version ofthis device may enablesubstantial improvement in quality of potable water.
