Culture of Microalgae using Anti-biofouling Photobioreator

Using nanovibrations to monitor biofouling.

The article proposes the use of the mechatronic surface sensor (MSS) to detect surface contamination. This methodology is based on the analysis of the vibration response of the monitored surface. In the present work a comparison between the responses of the MSS to different structural deposits build-up (Pseudomonas fluorescens biofilm--formed under turbulent and laminar flow and a silica deposi...

Environmentally Responsive Block Copolymers as Anti-biofouling Surfaces

Biofouling of ship-hulls is a problem of significant economic and environmental consequences. The accumulation of ‘slimes’ of microorganisms such as bacteria, green algae and diatoms, followed by the attachment of macroorganisms such as hydroids, sponges and barnacles, causes increased frictional drag on ships, higher consumption of fuel, and greater emission of greenhouse gases [1]. That marin...

Liquid-infused structured surfaces with exceptional anti-biofouling performance.

Bacteria primarily exist in robust, surface-associated communities known as biofilms, ubiquitous in both natural and anthropogenic environments. Mature biofilms resist a wide range of antimicrobial treatments and pose persistent pathogenic threats. Treatment of adherent biofilm is difficult, costly, and, in medical systems such as catheters or implants, frequently impossible. At the same time, ...

Biofouling Control Using Ultrasonic and Ultraviolet Treatments

ABSTRACT: Experiments were conducted at the Natural Energy Laboratory of Hawaii to determine the effectiveness of non-chemical techniques to control biofouling. The two techniques investigated were ultrasonic and ultraviolet. The colonization of microorganisms attracts higher order organisms; therefore, deactivation of microorganisms to prevent colony should reduce the fouling propensity. The m...
