Special Issue Information

Dear Colleagues,

The microbial biosensor makes it possible to measure the analyte as a quick, simple, and convenient method. Since Dr. Isao Karube (1942–2020) succeeded in the practical use of the first microbial biosensor for biochemical oxygen demand monitoring in 1983, many kinds of microbial biosensors for environmental monitoring have been studied and developed. To date, various improvements have been made to microbial biosensors in terms of, e.g., sensitivity, reproducibility, stability, specificity, and portability. Especially in the last decade, new and improved techniques have successfully been applied to microbial biosensor developments such as 3D printing for chip/cell/array or device fabrication, genetic engineering for microbial modification, materials science for microbial immobilization or signal detection, new techniques for transducer development, etc.

On the other hand, the global environment is becoming worse year by year, including climate change due to global warming. If we want humanity to survive, we have an obligation to transform our world—which is why in 2015, the United Nations Sustainable Development Summit adopted “The 2030 Agenda” and “The Sustainable Development Goals (SDGs)”. In this agenda, there are several goals that microbial biosensors are able to contribute to achieving, such as “conservation of water and soil resources”, “preservation of food safety”, etc. Thus, the scope of this Special Issue includes the topics listed below:

  • Application to environmental water or wastewater monitoring;
  • Application to estimate soil environment or bioremediation;
  • Application to agriculture, aquafarming, or aquaponics;
  • Micro/nanotechnology and novel materials applied to microbial biosensors;
  • Novel designs of chip/cell/array for microbial biosensors;
  • Novel instrumentation systems for microbial biosensors;
  • New solutions applied in microbial biosensors;
  • Interdisciplinary study leading to microbial biosensor development.

This Special Issue aims to highlight the most recent advances of microbial biosensors and participate in the development of microbial biosensors for SDGs efforts toward 2030. Research papers, short communications, and critical reviews are all welcome. If the author is interested in submitting a critical review, it would be helpful to discuss this with the Guest Editor before your submission.

The time-dependent response of metal-detecting whole-cell luminescent bacterial sensors is impacted by metal speciation/bioavailability in solution. The comprehensive understanding of such connections requires the consideration of the bacterial energy metabolism at stake and the effects of supplied food on cells’ capability to convert bioaccumulated metals into light. Accordingly, we investigated the time response (48 h assay) of PzntA-luxCDABE Escherichia coli Cd biosensors in media differing with respect to sources of amino acids (tryptone or Lysogeny Broth) and carbon (glucose, xylose and mixtures thereof). We show that the resulting coupling between the stringent cell response and glucose/xylose-mediated catabolite repressions lead to well-defined multimodalities and shapes of the bioluminescence signal over time. Based on a recent theory for the time–response of metal-sensing luminescent bacteria, successful theoretical reconstructions of the bioluminescence signals are reported under all Cd concentrations (0–20 nM) and nutritive conditions examined. This analysis leads to the evaluation of time-dependent cell photoactivity and qualitative information on metal speciation/bioavailability in solution. Biosensor performance and the position, shape, number, and magnitude of detected peaks are discussed in relation to the metabolic pathways operative during the successive light emission modes identified here over time. Altogether, the results clarify the contributions of metal/nutrient bio-availabilities and food quality to cell response typology. Full article

Foodborne microorganisms are an important cause of human illness worldwide. Two-thirds of human foodborne diseases are caused by bacterial pathogens throughout the globe, especially in developing nations. Despite enormous developments in conventional foodborne pathogen detection methods, progress is limited by the assay complexity and a prolonged time-to-result. The specificity and sensitivity of assays for live pathogen detection may also depend on the nature of the samples being analyzed and the immunological or molecular reagents used. Bacteriophage-based biosensors offer several benefits, including specificity to their host organism, the detection of only live pathogens, and resistance to extreme environmental factors such as organic solvents, high temperatures, and a wide pH range. Phage-based biosensors are receiving increasing attention owing to their high degree of accuracy, specificity, and reduced assay times. These characteristics, coupled with their abundant supply, make phages a novel bio-recognition molecule in assay development, including biosensors for the detection of foodborne bacterial pathogens to ensure food safety. This review provides comprehensive information about the different types of phage-based biosensor platforms, such as magnetoelastic sensors, quartz crystal microbalance, and electrochemical and surface plasmon resonance for the detection of several foodborne bacterial pathogens from various representative food matrices and environmental samples.

One of the main indices of the quality of water is the biochemical oxygen demand (BOD). A little over 40 years have passed since the practical application of the first microbial sensor for the determination of BOD, presented by the Japanese professor Isao Karube. This time span has brought new knowledge to and practical developments in the use of a wide range of microbial cells based on BOD biosensors. At present, this field of biotechnology is becoming an independent discipline. The traditional BOD analysis (BOD5) has not changed over many years; it takes no less than 5 days to carry out. Microbial biosensors can be used as an alternative technique for assessing the BOD attract attention because they can reduce hundredfold the time required to measure it. The review examines the experience of the creation and practical application of BOD biosensors accumulated by the international community. Special attention is paid to the use of multiple cell immobilization methods, signal registration techniques, mediators and cell consortia contained in the bioreceptor. We consider the use of nanomaterials in the modification of analytical devices developed for BOD evaluation and discuss the prospects of developing new practically important biosensor models.
