Abstract
Escherichia coli (E. coli) is a prevalent enteric bacterium and a necessary organism to monitor for food safety and environmental purposes. Developing efficient and specific methods is critical for detecting and monitoring viable E. coli due to its high prevalence. Conventional culture methods are often laborious and time-consuming, and they offer limited capability in detecting potentially harmful viable but non-culturable E. coli in the tested sample, which highlights the need for improved approaches. Hence, there is a growing demand for accurate and sensitive methods to determine the presence of viable E. coli. This paper scrutinizes various methods for detecting viable E. coli, including culture-based methods, molecular methods that target DNAs and RNAs, bacteriophage-based methods, biosensors, and other emerging technologies. The review serves as a guide for researchers seeking additional methodological options and aiding in the development of rapid and precise assays. Moving forward, it is anticipated that methods for detecting E. coli will become more stable and robust, ultimately contributing significantly to the improvement of food safety and public health.

Abstract
Salmonella is a common intestinal pathogen that can cause food poisoning and intestinal disease. The high prevalence of Salmonella necessitates efficient and sensitive methods for its identification, detection, and monitoring, especially of viable Salmonella. Conventional culture methods need to be more laborious and time-consuming. And they are relatively limited in their ability to detect Salmonella in the viable but non-culturable status if present in the sample to be tested. As a result, there is an increasing need for rapid and accurate techniques to detect viable Salmonella spp. This paper reviewed the status and progress of various methods reported in recent years that can be used to detect viable Salmonella, such as culture-based methods, molecular methods targeting RNAs and DNAs, phage-based methods, biosensors, and some techniques that have the potential for future application. This review can provide researchers with a reference for additional method options and help facilitate the development of rapid and accurate assays. In the future, viable Salmonella detection approaches will become more stable, sensitive, and fast and are expected to play a more significant role in food safety and public health.

Abstract
AbstractAnalytical techniques to measure organic matter in water, such as Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD5), and Total Organic Carbon (TOC) are widely used. Modifications have been proposed to make them faster, more sensitive, and more environmentally friendly. The purpose of producing a review over some time is to show the changes made on the standardized methods of each of these techniques, and to highlight the relationship between them in the process of ascertaining organic matter in water. Modifications to techniques COD and BOD entail several factors that need to be considered, namely: time, miniaturization, sensitivity, use of environmentally friendly reagents. Changes to TOC are focused on detection systems. Despite the advantages obtained by the modified techniques, traditional methods continue to be widely used, in most cases due to the lack of standardization of the new methods.

Abstract
Due to the serious threat of invasive fungal infections, there is an emergent need for improved a sensitive and more accurate diagnostic tests for detection of systemic pathogenic fungi and plant health. Traditional fungal diagnosis can only be achieved at later growing phases. The complex and difficult immunodiagnostic is also widely employed. Enzyme-based immunoassays which lead to cross-interaction with different fungi still also obeyed. A polymerase chain reactions (PCRs)- based molecular diagnosis are does not enable precise identification of fungal pathogens, or the ability to test isolates for drug sensitivity. In the future, biosensing technologies and nanotechnological tools, will improve diagnosis of pathogenic fungi through a specific and sensitive pathogen detection. This report systematically reviews the most prominent biosensor trends for fungi detection.

Abstract
Cytotoxic effects of menadione on normal and cytochrome c-deficient yeast cells were examined on the basis of the cell growth rate, NAD(P)H concentration, reactive oxygen production, plasma membrane H+-ATPase activity, and ethanol production. In aerobically or anaerobically cultured yeast cells, NAD(P)H concentration decreased with increasing concentration of menadione, and the recovery of NAD(P)H concentration was proportional to the cell growth rate. However, there was no relationship among the inhibition of the cell growth and reactive oxygen production, plasma membrane H+-ATPase activity, and ethanol production. Among them, ethanol production showed resistance to the cytotoxicity of menadione, suggesting the resistance of glycolysis to menadione. The growth inhibitory effect of menadione depended on the rapid decrease and the recovery of NAD(P)H rather than production of reactive oxygen species regardless of aerobic culture or anaerobic culture and presence or absence of mitochondrial function. The recovery of NAD(P)H concentration after the addition of menadione might depend on menadione-resistant glycolytic enzymes. The rapid decrease in NAD(P)H concentration in yeast cells was observed after the addition of menadione. The recovery of NAD(P)H concentration after addition of menadione was proportional to the cell growth rate. The above phenomena were observed in suspension of aerobically or anaerobically cultured yeast cells. The above phenomena were observed in suspension of normal or cytochrome c-deficient yeast cells.

Abstract
Chemiluminescent (CL) reactions are powerful analytical tools and are present in commercially available everyday objects such as glow sticks. Herein, the photons generated by chemiluminescence are exploited to induce covalent bond breakage and formation, using a chemically generated photonic field at ambient temperature through space as energy transducer. Remarkably, the generated photons enable both the cleavage of species generating radicals as well as the execution of [2 + 2] cycloadditions, demonstrating that disparate types of reactions can be triggered. The herein-presented photochemical concept establishes the field of CL-induced photochemistry, which is poised to enable photochemical transformations in situations where physical light sources, such as lamps, LEDs, and lasers cannot be employed, including in biological environments.

Abstract
Membrane permeant acetaldehyde and menadione induced the synergistic reduction of toluylene blue (TB) acting as non-membrane permeant redox indicator in yeast cell suspension. NADH and acetaldehyde also induced the synergistic TB reduction in permeabilized yeast cells and phosphate buffer, but menadione had no ability to promote TB reduction. The pre-incubation of acetaldehyde inhibited the above synergistic reduction of TB in intact and permeabilized yeast cell suspension. The pre-incubation of acetaldehyde might promote NADH oxidation by alcohol dehydrogenase, because acetaldehyde decreased the intracellular NAD(P)H concentration. The above facts indicate that the synergistic reduction of TB is controlled by the order of addition of menadione and acetaldehyde. The synergistic reduction of TB by menadione and acetaldehyde was proportional to viable yeast cell number from 104 to 2×106 cells/ml, and this assay was applicable to cytotoxicity test. The time required for the above assay was only 2 min.

Abstract
Fungal diseases in commercially important plants results in a significant reduction in both quality and yield, often leading to the loss of an entire plant. In order to minimize the losses, it is essential to detect and identify the pathogens at an early stage. Early detection and accurate identification of pathogens can control the spread of infection. The present article provides a comprehensive overview of conventional methods, current trends and advances in fungal pathogen detection with an emphasis on biosensors. Traditional techniques are the "gold standard" in fungal detection which relies on symptoms, culture-based, morphological observation and biochemical identifications. In recent times, with the advancement of biotechnology, molecular and immunological approaches have revolutionized fungal disease detection. But the drawback lies in the fact that these methods require specific and expensive equipments. Thus, there is an urgent need for rapid, reliable, sensitive, cost effective and easy to use diagnostic methods for fungal pathogen detection. Biosensors would become a promising and attractive alternative, but they still have to be subjected to some modifications, improvements and proper validation for on-field use.

Abstract
Menadione promoted the production of active oxygen species (AOS) in both yeast cell suspension and the crude enzymes from the cells, but menadione sodium bisulfite (MSB) had little effect on the production of AOS in the cell suspension. MSB kept the stable increase in the electron transfer from intact yeast cells to anode compared to menadione, but the electron transfer promoted by MSB was inhibited in permeabilized yeast cell suspension. Menadione promoted oxidation of NAD(P)H much faster than MSB in permeabilized yeast cell suspension, suggesting the oxidative stress due to consumption of NAD(P)H. The proliferation of yeast cells was inhibited by menadione under aerobic conditions rather than anaerobic conditions, and the inhibitory effect was reduced by superoxide dismutase and catalase. The effect of MSB on the proliferation was much smaller than that of menadione. The above facts suggest that harmless MSB promotes the electron transfer from plasma membrane of yeast cells to anode. On the other hand, harmful menadione might promote the electron transfer from cytosol and plasma membrane to anode and dissolved oxygen.

Abstract
UNLABELLED Previous studies revealed a close connection between heat shock and manganese-dependent superoxide dismutase (SOD2) in eukaryotes. This paper shows that SOD mimics based on manganese complexes caused an increase in thermotolerance for a mutant fission yeast deficient in mitochondrial superoxide dismutase. Manganese compounds used for tests are SOD mimics, from two different classes: salen manganese (EUK-8) and Mn porphyrin (Mn(III)TE-2-PyP(5+)). The tests were conducted using a Schizosaccharomyces pombe model, comparing the viability of two strains at chronic heat stress (37°C)--a wild type versus a strain with the mitochondrial superoxide dismutase gene deleted [SOD2(-)]. The presence of massive free radical species in S. pombe SOD2(-) was demonstrated using a luminol-enhanced chemiluminescence test derived from a menadione-mediated survival protocol. CONCLUSIONS Survival tests revealed that the SOD2-deleted S. pombe is about 100 times more sensitive to heat stress than the wild-type strain. This survival deficit can be corrected by EUK-8 and Mn(III)TE-2-PyP(5+) to almost the same degree but not by manganese chloride II (MnCl(2)). Using a simple spot assay for viability testing, this new model proved to be an easy alternative for the initial estimation of manganese SOD mimics efficiency.

Abstract
Incidental contamination of foods by pathogenic bacteria and/or their toxins is a serious threat to public health and the global economy. The presence of food-borne pathogens and toxins must be rapidly determined at various stages of food production, processing, and distribution. Producers, processors, regulators, retailers, and public health professionals need simple and cost-effective methods to detect different species or serotypes of bacteria and associated toxins in large numbers of food samples. This review addresses the desire to replace traditional microbiological plate culture with more timely and less cumbersome rapid, biosensor-based methods. Emphasis focuses on high-throughput, multiplexed techniques that allow for simultaneous testing of numerous samples, in rapid succession, for multiple food-borne analytes (primarily pathogenic bacteria and/or toxins).

Abstract
This study was designed to compare the effectiveness of acidified sodium chlorite (ASC) and sodium hypochlorite (NaClO) in reducing several Escherichia coli strains isolated from different retail meat and fresh produce. Forty nonpathogenic E. coli strains were isolated and used in this study. A type strain of E. coli (JCM 1649) and four O157:H7 serotypes of E. coli (CR-3, MN-28, MY-29, and DT-66) were used as reference. In vitro assay results revealed that the viable cell counts of each isolated E. coli strain and control strains exhibited a reduction of ∼ 4.3 ± 0.9 log and 7.8 ± 1.7 log CFU/mL after a 3-minute exposure to 100 mg/L NaClO and 20 mg/L ASC (pH 4.6), respectively, at 25°C, when compared with the viable bacterial counts obtained from phosphate-buffered saline. The one exception was the flocs-forming strain, which showed a reduction of only 1.0 log CFU/mL with both disinfectants. However, reductions of only 1.7 ± 0.3 log and 1.9 ± 0.4 log CFU/g were observed in lettuce after 5 minutes of washing with NaClO and ASC, respectively. On the other hand, reductions of 1.6 ± 0.2 log and 1.6 ± 0.4 log CFU/g were observed in spinach after 5 minutes of washing with NaClO and ASC, respectively. No reduction in the population was observed after washing the inoculated, fresh-cut vegetables with distilled water only. No significant difference in the reduction of E. coli was observed among all the tested strains with both sanitizers in the in vivo assay. These data suggest that the tested sanitizers exhibit a similar reduction of the surface-attached E. coli on leafy vegetables irrespective of the strain source.

Abstract
INTRODUCTION Rapid determination of microorganisms' antibiotic susceptibility remains a great challenge for the clinical diagnosis of infectious diseases. In this study, we compare three rapid bioluminescent antibiotic susceptibility tests with the conventional normalised microdilution method. METHODS The susceptibility of two bacterial and two fungal strains to a 6h incubation with one of eight standard antibiotics was investigated by the ATP, AK and QNO bioluminescent methods. RESULTS Three rapid and accurate antibiotic susceptibility testing were investigated performing ATP, AK and QNO bioluminescent assays. All the results were in accordance with those obtained using a standard microdilution assay. All these methods were sensitive and faster than the previously well-known ones. DISCUSSION The development of bioluminescent determination methods could lead to accurate and useful antibiotic susceptibility testing.

Abstract
Chemiluminescent assay for menadione-catalyzed H(2)O(2) production by mammalian cells was modified by luminol chemiluminescence with microperoxidase instead of peroxyoxalate chemiluminescence with carcinogenic fluorescent materials. Luminol can be used as a common chemiluminescent reagent for the determination of viable mammalian cells and bacteria.

Menadione-catalyzed luminol luminescent assay as a novel evaluation method of ethanol tolerance in yeast cells. Anal Biochem 2008; 385:115-9. [PMID: 19028448 DOI: 10.1016/j.ab.2008.10.038] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2008] [Revised: 10/07/2008] [Accepted: 10/29/2008] [Indexed: 11/20/2022]
Abstract
In this study, ethanol inhibited the growth and glucose-induced proton release of yeast cells in a dose-dependent manner. On the other hand, ethanol tolerance of menadione-catalyzed luminol luminescence by yeast cells increased with increasing ethanol concentrations in the growth medium. The intracellular reduced-form nicotinamide adenine dinucleotide (NADH) concentration also increased with increasing ethanol concentrations in the medium and was enough to maintain constant menadione-catalyzed luminol luminescence. These facts suggest that the menadione-catalyzed luminol luminescent assay depending on a NADH:quinone reductase and NADH generation system is useful as a new evaluation assay for assessing the vitality of ethanol-stressed yeast cells, whereas the glucose-induced proton release assay is expected to be useful for the evaluation of cell growth under ethanol stress.

Abstract
All Enterococcus spp., isolated from environmental water samples (n=81), emitted a high chemiluminescence signal in the presence of luminol (10(-2) M). Kinetic studies of chemiluminescence show a close correlation between chemiluminescence and growth curves during the exponential phase, with a maximum chemiluminescence reached just before bacterial growth entered in the stationary phase. On the other hand, genera closely related to Enterococcus such as Streptococcus or Lactococcus produced a very weak chemiluminescent signal. Chemiluminescence of enterococci could therefore offer a rapid test, in aiding the identification of the genus Enterococcus and in the survey of the microbiological quality of water supplies.
