“…There are also biosensors based on artificially formed biofilms. In [ 107 ], bacteria S. oneidensis were mixed with magnetic Fe 3 O 4 nanoparticles to create a magnetically constructed EAB biofilm. The developed biosensor proved to be effective both for the detection of phenol and for the determination of heavy metal ions in wastewater samples with a detection limit of 0.07 mg/L.…”

Microbial biofilms present one of the most widespread forms of life on Earth. The formation of microbial communities on various surfaces presents a major challenge in a variety of fields, including medicine, the food industry, shipping, etc. At the same time, this process can also be used for the benefit of humans—in bioremediation, wastewater treatment, and various biotechnological processes. The main direction of using electroactive microbial biofilms is their incorporation into the composition of biosensor and biofuel cells This review examines the fundamental knowledge acquired about the structure and formation of biofilms, the properties they have when used in bioelectrochemical devices, and the characteristics of the formation of these structures on different surfaces. Special attention is given to the potential of applying the latest advances in genetic engineering in order to improve the performance of microbial biofilm-based devices and to regulate the processes that take place within them. Finally, we highlight possible ways of dealing with the drawbacks of using biofilms in the creation of highly efficient biosensors and biofuel cells.

“…The results reveal low TCEP toxicity, influencing environmental restrictions [28].This paper describes how magnetically generated electrochemically active biofilms can be used to detect water toxicity instantly. Utilizing bacterial metabolic activity enables quick contaminant detection, providing realtime water quality monitoring and pollution control [29].This paper examines biosensors for wastewater monitoring, highlighting enzymatic, microbiological, and immunological kinds. The incorporation of nanotechnology improves sensitivity, enabling real-time, on-site monitoring for ecofriendly wastewater treatment solutions [30].This paper describes a biomonitoring tool that use recombinant bioluminescent bacteria to determine toxicity in contaminated areas.…”

Crown-of-thorns starfish (COTS), which eats coral is becoming increasingly common. Coral reefs, which are highly valued for their aesthetic appeal and ecological importance, are seriously threatened. This collection of carefully shot underwater photo sequences covering the whole Great Barrier Reef at different times and places is an invaluable resource for understanding and mitigating the negative effects of commercial overfishing (COTS) on these fragile ecosystems. Due to the predatory nature of the crown-of-thorns starfish coral reefs face significant threats necessitating urgent innovation in methods to control their population.
