Abstract

This paper introduces a novel prototype for removal of Pseudomonas from water samples. Bacterial cells have the tendency to get attracted towards species specific chemicals justifying a phenomenon known as chemotaxis. We designed a strip integrating a combination of serine, a pseudomonas specific chemo-attractant and honey to attract and inhibit the bacteria in situ. Upon dipping the serine side of the strip, pseudomonal cells were attracted towards it. The porous property of the strip facilitates the ‘trapping’ and subsequent diffusion of the bacterial cells towards honey-adsorbed end of the strip. Honey, a natural antimicrobial agent, has garnered attention in its effective inhibitory role in Pseudomonal biofilms and wound infections. This ‘honeytrap’ reportedly leads to targeted elimination of Pseudomonas, hence facilitating its removal from water. The percentage removal 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 the potable water, enters circulation due to improperly maintained plumbing fixtures and storage facilities. P. aeruginosa has been implicated as a causative agent in gastroenteritis, keratitis, endocarditis, urinary tract infections and septicemia amongst many, thus, making it a potent health risk. Honeytrap strip is an easy to use, biodegradable and cost-effective sustainable solution, which can passively neutralize pseudomonas from water. The scaled-up version of honeytrap device may help us in achieving better outcomes in terms of potable water with substantial improvement in quality of life.
