Microorganisms 2023; 11:microorganisms11020329. [PMID: 36838294 PMCID: PMC9967617 DOI: 10.3390/microorganisms11020329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 01/21/2023] [Accepted: 01/23/2023] [Indexed: 01/31/2023] Open
Abstract
Traditional probiotics comprise mainly lactic acid bacteria that are safe for human use, tolerate acid and bile, and adhere to the epithelial lining and mucosal surfaces. In this study, one hundred commercial and non-commercial strains that were isolated from human feces or vaginal samples were tested with regards to overall growth in culture media, tolerance to acid and bile, hydrogen peroxide (H2O2) production, and adhesion to vaginal epithelial cells (VECs) and to blood group antigens. As a result, various of the tested lactobacilli strains were determined to be suitable for gastrointestinal or vaginal applications. Commercial strains grew better than the newly isolated strains, but tolerance to acid was a common property among all tested strains. Tolerance to bile varied considerably between the strains. Resistance to bile and acid correlated well, as did VEC adhesion and H2O2 production, but H2O2 production was not associated with resistance to bile or acid. Except for L. iners strains, vaginal isolates had better overall VEC adhesion and higher H2O2 production. Species- and strain-specific differences were evident for all parameters. Rank-ordered clustering with nine clusters was used to identify strains that were suitable for gastrointestinal or vaginal health, demonstrating that the categorization of strains for targeted health indications is possible based on the parameters that were measured in this study.

Abstract
There are numerous bacteria reside within the mammalian gastrointestinal tract. Among the intestinal bacteria, Akkermansia, Bacteroides, Bifidobacterium, and Ruminococcus closely interact with the intestinal mucus layer and are, therefore, known as mucosal bacteria. Mucosal bacteria use host or dietary glycans for colonization via adhesion, allowing access to the carbon source that the host’s nutrients provide. Cell wall or membrane proteins, polysaccharides, and extracellular vesicles facilitate these mucosal bacteria-host interactions. Recent studies revealed that the physiological properties of Bacteroides and Bifidobacterium significantly change in the presence of co-existing symbiotic bacteria or markedly differ with the spatial distribution in the mucosal niche. These recently discovered strategic colonization processes are important for understanding the survival of bacteria in the gut. In this review, first, we introduce the experimental models used to study host-bacteria interactions, and then, we highlight the latest discoveries on the colonization properties of mucosal bacteria, focusing on the roles of the cell surface architecture regarding Bacteroides and Bifidobacterium.

Abstract
One of the main challenges in the field of drug delivery remains the development of strategies to efficiently transport pharmaceuticals across mucus barriers, which regulate the passage and retention of molecules and particles in all luminal spaces of the body. A thorough understanding of the molecular mechanisms, which govern such selective permeability, is key for achieving efficient translocation of drugs and drug carriers. For this purpose, model systems based on purified mucins can contribute valuable information. In this review, we summarize advances that were made in the field of drug delivery research with such mucin-based model systems: First, we give an overview of mucin purification procedures and discuss the suitability of model systems reconstituted from purified mucins to mimic native mucus. Then, we summarize techniques to study mucin binding. Finally, we highlight approaches that made use of mucins as building blocks for drug delivery platforms or employ mucins as active compounds.

Abstract
This study aimed to evaluate the ratio of adherence of lactic acid bacteria (LAB) to porous fine ceramics in order to develop a novel LAB-rich pickle container for the production of functional fermented vegetables. Some LAB were isolated from the salted rice bran used for pickling (Nukadoko in Japanese). These isolates were classified in Lactobacillus namurensis by phylogenetic analysis. Some pottery-shard (PS) samples were prepared by varying the mixing rate of polyacetal (POM) resin to clay (0–30% (v/v)) and the burning temperature (1000 °C or 1100 °C). A test of the adherence of strain GYP-74 to the PSs was performed. The results showed that the adherence rate was significantly higher in the PSs burned at 1100 °C as compared with those burned at 1000 °C. A pore distribution analysis showed that pore sizes of less than a few µm and pore sizes in the range of a few µm to a few hundred µm were mainly distributed in the PSs without and with POM, respectively. X-ray diffraction analysis showed that both PSs with and without POM contained quartz and hematite. The PSs burned at 1000 °C and 1100 °C specifically contained microcline and mullite, respectively. This study revealed the basal information regarding what makes PSs adequate for LAB adhesion.

Selection of Immunobiotic Ligilactobacillus salivarius Strains from the Intestinal Tract of Wakame-Fed Pigs: Functional and Genomic Studies. Microorganisms 2020; 8:microorganisms8111659. [PMID: 33114778 PMCID: PMC7716343 DOI: 10.3390/microorganisms8111659] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Revised: 10/23/2020] [Accepted: 10/25/2020] [Indexed: 12/11/2022] Open
Abstract
In this article, Ligilactobacillus salivarius FFIG strains, isolated from the intestinal tract of wakame-fed pigs, are characterized according to their potential probiotic properties. Strains were evaluated by studying their interaction with porcine intestinal epithelial (PIE) cells in terms of their ability to regulate toll-like receptor (TLR)-3- or TLR4-mediated innate immune responses, as well as by assessing their adhesion capabilities to porcine epithelial cells and mucins. These functional studies were complemented with comparative genomic evaluations using the complete genome sequences of porcine L. salivarius strains selected from subgroups that demonstrated different “immune” and “adhesion” phenotypes. We found that their immunomodulatory and adhesion capabilities are a strain-dependent characteristic. Our analysis indicated that the differential immunomodulatory and adhesive activities of FFIG strains would be dependent on the combination of several surface structures acting simultaneously, which include peptidoglycan, exopolysaccharides, lipoteichoic acid, and adhesins. Of note, our results indicate that there is no correlation between the immunomodulatory capacity of the strains with their adhesion ability to mucins and epithelial cells. Therefore, in the selection of strains destined to colonize the intestinal mucosa and modulate the immunity of the host, both properties must be adequately evaluated. Interestingly, we showed that L. salivarius FFIG58 functionally modulated the innate immune responses triggered by TLR3 and TLR4 activation in PIE cells and efficiently adhered to these cells. Moreover, the FFIG58 strain was capable of reducing rotavirus replication in PIE cells. Therefore, L. salivarius FFIG58 is a good candidate for further in vivo studying the protective effect of lactobacilli against intestinal infections in the porcine host. We also reported and analyzed, for the first time, the complete genome of several L. salivarius strains that were isolated from the intestine of pigs after the selective pressure of feeding the animals with wakame. Further genomic analysis could be of value to reveal the metabolic characteristics and potential of the FFIG strains in general and of the FFIG58 strain, in particular, relating to wakame by-products assimilation.

Ribosome-Engineered Lacticaseibacillus rhamnosus Strain GG Exhibits Cell Surface Glyceraldehyde-3-Phosphate Dehydrogenase Accumulation and Enhanced Adhesion to Human Colonic Mucin. Appl Environ Microbiol 2020; 86:AEM.01448-20.

Abstract
We sought to apply ribosome engineering (RE) to probiotic lactic acid bacteria and to verify RE’s impact. Here, we showed that one mutant of RE Lacticaseibacillus rhamnosus GG (LGG-MTK56N) bore a GAPDH on the cell surface; the GAPDH was exported via an ABC transporter. Compared to the wild-type parent, LGG-MTK56N adhered more strongly to human colonic mucin and exhibited a distinct cell size and shape. These findings demonstrate that RE in LGG-MTK56N yielded dramatic changes in protein synthesis, protein transport, and cell morphology and affected adherence to human colonic mucin. Differences in individual host responses have emerged as an issue regarding the health benefits of probiotics. Here, we applied ribosome engineering (RE) technology, developed in an actinomycete study, to Lacticaseibacillus rhamnosus GG (LGG). RE can effectively enhance microbial potential by using antibiotics to induce spontaneous mutations in the ribosome and/or RNA polymerase. In this study, we identified eight types of streptomycin resistance mutations in the LGG rpsL gene, which encodes ribosomal protein S12. Notably, LGG harboring the K56N mutant (LGG-MTK56N) expressed high levels of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) on the cell surface compared with the LGG wild type (LGG-WT). GAPDH plays a key role in colonic mucin adhesion. Indeed, LGG-MTK56N significantly increased type A human colonic mucin adhesion compared to LGG-WT in experiments using the Biacore system. The ability to adhere to the colon is an important property of probiotics; thus, these results suggest that RE is an effective breeding strategy for probiotic lactic acid bacteria.

Abstract
Cell biology is driven by complex networks of biomolecular interactions. Characterizing the kinetic and thermodynamic properties of these interactions is crucial to understanding their role in different physiological processes. Surface plasmon resonance (SPR)-based approaches have become a key tool in quantifying biomolecular interactions, however conventional approaches require isolating the interacting components from the cellular system. Cell-based SPR approaches have recently emerged, promising to enable precise measurements of biomolecular interactions within their normal biological context. Two major approaches have been developed, offering their own advantages and limitations. These approaches currently lack a systematic exploration of 'best practices' like those existing for traditional SPR experiments. Toward this end, we describe the two major approaches, and identify the experimental parameters that require exploration, and discuss the experimental considerations constraining the optimization of each. In particular, we discuss the requirements of future biomaterial development needed to advance the cell-based SPR technique.

Abstract
Mucus in the gastrointestinal (GI) tract is the primary point-of-interaction between humans and their gut microbiota. This intimates that mucus not only ensures protection against endogenous and exogenous opportunists but also provisions for the human microbiota to reside and flourish. With the emergence of living therapeutics, engineered microbes can deliver and produce increasingly complex medicine, and controlling the mucoadhesive properties of different microbial chassis can dictate dose-response in a patient. Here we present a redesigned, in vitro, plate-based assay to measure the mucus adhesion of various probiotics. Cell-mucus interactions were isolated by immobilizing mucus to the plate surface. Binding parameters were derived for each probiotic strain by measuring cell adhesion over a wide range of cell concentrations, providing dose-dependent adhesion metrics. Surface proteins and cell components known to influence mucoadhesion were then heterologously expressed or altered in Lactococcus lactis MG1363 and Escherichia coli Nissle 1917 to control mucus-binding capacity, avidity, and cooperativity.

Abstract
ABSTRACT
A close symbiotic relationship exists between the intestinal microbiota and its host. A critical component of gut homeostasis is the presence of a mucus layer covering the gastrointestinal tract. Mucus is a viscoelastic gel at the interface between the luminal content and the host tissue that provides a habitat to the gut microbiota and protects the intestinal epithelium. The review starts by setting up the biological context underpinning the need for experimental models to study gut bacteria-mucus interactions in the digestive environment. We provide an overview of the structure and function of intestinal mucus and mucins, their interactions with intestinal bacteria (including commensal, probiotics and pathogenic microorganisms) and their role in modulating health and disease states. We then describe the characteristics and potentials of experimental models currently available to study the mechanisms underpinning the interaction of mucus with gut microbes, including in vitro, ex vivo and in vivo models. We then discuss the limitations and challenges facing this field of research.

Specific expression pattern of tissue cytokines analyzed through the Surface Acoustic Wave technique is associated with age-related spontaneous benign prostatic hyperplasia in rats. Biochem Biophys Rep 2018; 14:26-34. [PMID: 29872731 PMCID: PMC5986627 DOI: 10.1016/j.bbrep.2018.03.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2017] [Revised: 02/06/2018] [Accepted: 03/22/2018] [Indexed: 12/27/2022] Open
Abstract
The aim of the study reported herein was to evaluate the suitability of the Surface Acoustic Wave (SAW) technique as a possible diagnostic tool in benign prostatic hyperplasia (BPH). Moreover, for the first time, the BPH model was a totally physiological using naturally aged rats with spontaneous, age-related BPH instead of the pharmacologically induced models usually used. Eighteen male Wistar rats were distributed according to their age: 6 weeks (young), 12 weeks (adult) and 12 months (old) old. Prostate gland was removed and analyzed by mini-arrays, Western blotting (WB) and SAW techniques. Mini-arrays indicated that there were significant differences in the expression of 29/34 inflammation-related cytokines. WB was carried out to confirm the results after selection of 4 cytokines from which one showed no changes, namely PDGF-AA, and the other three, which significantly increase in older animals, were CD86, β-NGF and VEGF. Notwithstanding, WB of old rats yielded confusing results due to an anomalous migration of proteins, dismissing this technique as an useful tool in these animals. Accurate results in old rats were uniquely obtained by using the SAW technique. Thus, SAW analysis showed that there were not differences among groups in the amount of PDGF-AA. On the contrary, SAW analysis showed that amounts of CD86, β-NGF and VEGF in old rats were 2.0, 1.9 and 5.7-fold higher than that from young ones, respectively. These results indicate that SAW is a highly accurate technique for determining changes in the cytokines expression in BPH. Diagnosis of prostate alterations can be improved by using the SAW technique. Study of prostate alterations can be optimized by using an age-related animal model. VEGF is a sensitive marker of bening prostatic hyperplasia.

Ogura T, Tanaka Y, Toyoda H. Whole cell-based surface plasmon resonance measurement to assess binding of anti-TNF agents to transmembrane target. Anal Biochem 2016; 508:73-7.

Abstract
We developed a technique for the measurement of surface plasmon resonance (SPR) to detect interactions of anti-tumor necrosis factor (TNF) agents with transmembrane TNF-α (mTNF-α) on living whole cells. The injection of a suspension of mTNF-α expressing Jurkat cells, used as an analyte, gave a clear binding response to anti-TNF agents, such as etanercept, infliximab and adalimumab, immobilized on sensorchip. The binding response of the analyte cells increased in a concentration-dependent manner and was competitively reduced by adding soluble TNF receptors to the analyte cell suspension. Treatment of analyte cells with free anti-TNF agent before injection reduced the binding response between the analyte cells and immobilized-etanercept on sensorchip, and the inhibitory effect of free anti-TNF agent was concordant with the affinity of anti-TNF agent for soluble TNF-α. These findings indicate that the SPR response arises from specific binding between anti-TNF agent and its target on cell membrane.

Abstract
Surface plasmon resonance (SPR) is a popular technique that allows for sensitive, specific, label-free and real-time assessment of biomolecular interactions. SPR is a nondestructive, modular and flexible tool for various applications in biomedical sciences ranging from cell sorting, cell surface characterization and drug discovery. In this review, we will discuss more specifically how SPR is used to monitor the dynamics of various types of cellular binding events and morphological adherence changes in response to external stimuli.

Abstract
The aim of this study was to assess the adhesion of Bifidobacterium strains to acidic carbohydrate moieties of porcine colonic mucin. Mucins were extracted and purified via gel filtration chromatography followed by density-gradient ultracentrifugation. The presence of sulfated and sialylated carbohydrates in mucins was shown by enzyme-linked immunosorbent assays using PGM34 and HMC31 monoclonal antibodies (mAbs), respectively. Adhesion of Bifidobacterium strains to mucin preparations was markedly affected by the degree of purification. In eight of 22 strains, we observed increased adhesion to mucin preparations purified by ultracentrifugation. Moreover, in some of these eight strains, adhesion to mucin was reduced by pretreatment with sulfatase and/or sialidase, and competitively inhibited by pretreatment with PGM34 and/or HCM31 mAbs. Our results showed that some Bifidobacterium strains adhered to sulfo- and/or sialomucin and were able to recognize carbohydrate structures of the mAbs epitopes.

Abstract
The presence of Escherichia coli (E. coli) in food and drinking water is a chronic problem worldwide. Protecting food against bacterial contamination and rapid diagnosis of infection require simple and rapid assays for detection of bacterial pathogens, including E. coli O157:H7. Here we report a rapid and novel colorimetric method for detecting E. coli O157:H7. This colorimetric method is based on the catalytic oxidation of the peroxidase substrate 3,3,5,5-tetramethylbenzidine by hydrogen peroxide using 4-mercaptophenylboronic acid-functioned Au@Pt nanoparticles adsorbed on the surface of E. coli O157:H7. The assay showed excellent sensitivity both with the naked eye and based on absorbance measurements. The absorbance at 652 nm was proportional to the concentration of E. coli O157:H7 ranging from 7 to 6 × 10(6) cfu mL(-1) with a limit of detection of 7 cfu mL(-1). The total detection time was less than 40 min.

Abstract
Adhesion of bacteria to mucus may favor their persistence within the gut and their beneficial effects to the host. Interactions between pig gastric mucin (PGM) and a natural isolate of Lactococcus lactis (TIL448) were measured at the single-cell scale and under static conditions, using atomic force microscopy (AFM). In parallel, these interactions were monitored at the bacterial population level and under shear flow. AFM experiments with a L. lactis cell-probe and a PGM-coated surface revealed a high proportion of specific adhesive events (60%) and a low level of non-adhesive ones (2%). The strain muco-adhesive properties were confirmed by the weak detachment of bacteria from the PGM-coated surface under shear flow. In AFM, rupture events were detected at short (100−200 nm) and long distances (up to 600−800 nm). AFM measurements on pili and mucus-binding protein defective mutants demonstrated the comparable role played by these two surface proteinaceous components in adhesion to PGM under static conditions. Under shear flow, a more important contribution of the mucus-binding protein than the pili one was observed. Both methods differ by the way of probing the adhesion force, i.e. negative force contact vs. sedimentation and normal-to-substratum retraction vs. tangential detachment conditions, using AFM and flow chamber, respectively. AFM blocking assays with free PGM or O-glycan fractions purified from PGM demonstrated that neutral oligosaccharides played a major role in adhesion of L. lactis TIL448 to PGM. This study dissects L. lactis muco-adhesive phenotype, in relation with the nature of the bacterial surface determinants.

Abstract
Dynamic fluoroimmunoassay with a flow-through system using optical fiber probes consisting of polystyrene was developed and applied to a quantitative detection of E. coli O157:H7. The system measures E. coli as fluorescence of sandwich-type immune complexes formed by capture antibodies immobilized on the surface of the probe, E. coli cells, and fluorescently labeled detection antibodies. Excitation was carried out using an evanescent wave from the probe. Resulting fluorescence recoupled into the probe was detected by a photodiode. The assay system was constructed with a flow cell which was available for sequential injection of experimental reagents. In vitro characterization was performed using the flow cell, and the calibration range of E. coli O157:H7 was from 10(3) to 10(7) cells/mL. The measurement for each sample was completed within 12 min. Furthermore, it was also possible to estimate the concentrations of E. coli O157:H7 by the increasing rate of fluorescence during binding reaction of detection antibodies to antigens. This minimized the time for measurement down to 6 min. The system is suitable for rapid and direct determination for microorganisms or bacteria in food, clinical, and environmental sources.

An adhesin-like protein, Lam29, from Lactobacillus mucosae ME-340 binds to histone H3 and blood group antigens in human colonic mucus. Biosci Biotechnol Biochem 2012; 76:1655-60.

Abstract
A cell-surface 29-kDa protein (Lam29, cysteine-binding protein of the ABC transporter) from Lactobacillus mucosae ME-340 showed an adhesin-like property for human ABO blood group antigens expressed on the gastrointestinal mucosa. In addition, here we report that Lam29 also bound to an 18-kDa protein on human colonic mucus. By ligand blot assay and N-terminal amino acid sequence of the protein, it was identified as human histone H3. By ligand blot and microplate binding assays with recombinant histone H3, binding between Lam29 and histone H3 was confirmed. The adhesion of ME-340 cells to histone H3 was significantly inhibited by 26% after the addition of 2.5 mg/mL Lam29 as compared to the absence of Lam29 (p<0.01). By GHCl extraction and transcription attenuation of ME-340 cells, binding reduction of ME340 cells against histone H3 was detected at 12% and 13% respectively, as compared to control cells by the BIACORE assay (p<0.01). These data indicate that Lam29 shows multiple binding activities to blood group antigens and histone H3 in human colonic mucus. This is the first report to indicate that lactobacilli expressing Lam29 adhere to histone H3 on gastrointestinal mucosa.

Abstract
PURPOSE Development of the first in vitro method based on biosensor chip technology designed for probing the interfacial interaction phenomena between transmembrane ocular mucins and adhesive polymers and dendrimers intended for ophthalmic administration. METHODS The surface plasmon resonance (SPR) technique was used. A transmembrane ocular mucin surface was prepared on the chip surface and characterized by QCM-D (Quartz Crystal Microbalance with Dissipation) and XPS (X-ray photoelectron spectroscopy). The mucoadhesive molecules tested were: hyaluronic acid (HA), carboxymethyl cellulose (CMC), hydroxypropylmethyl cellulose (HPMC), chitosan (Ch) and polyamidoamine dendrimers (PAMAM). RESULTS While Ch originated interfacial interaction with ocular transmembrane mucins, for HA, CMC and HPMC, chain interdiffusion seemed to be mandatory for bioadherence at the concentrations used in ophthalmic clinical practise. Interestingly, PAMAM dendrimers developed permanent interfacial interactions with transmembrane ocular mucins whatever their surface chemical groups, showing a relevant importance of co-operative effect of these multivalent systems. Polymers developed interfacial interactions with ocular membrane-associated mucins in the following order: Ch(1 %) > G4PAMAM-NH(2)(2 %) = G4PAMAM-OH(2 %) > G3.5PAMAM-COOH(2 %)>> CMC(0.5 %) = HA(0.2 %) = HPMC(0.3 %). CONCLUSIONS The method proposed is useful to discern between the mucin-polymer chemical interactions at molecular scale. Results reinforce the usefulness of chitosan and dendrimers as polymers able to increase the retention time of drugs on the ocular surface and hence their bioavailability.

Abstract
Toward future applications to the discovery of drugs against membrane receptors on pathological cells, an intact-cell-based surface plasmon resonance (SPR) methodology has been developed. The injection of a suspension of epidermal carcinoma A431 cells (5×10(7)cells/ml), as an analyte, generated clear SPR responses to epidermal growth factor (EGF) immobilized on the sensor chip. Because the responses were competitively reduced by the free ligand EGF, added to the analyte cell suspension, they certainly reflect the specific interaction of the immobilized EGF with the extracellular region of its receptor, which is highly expressed on the surface of the A431 cells.

Abstract
A novel, fast and sensitive determination strategy for E. coli O157:H7 has been developed by combination of ligandmagnetic nanoparticles (LMNPs) enrichment with a fluorescent silica nanoparticles (FSiNPs) based two-color flow cytometry assay (LMNPs@FSiNPs-FCM). E. coli O157:H7 was first captured and enriched through the lectin concanavalin A (Con A) favored strong adhesion of E. coli O157:H7 to the mannose-conjugated magnetic nanoparticles. The enriched E. coli O157:H7 was further specially labeled with goat anti-E. coli O157:H7 antibody modified RuBpy-doped FSiNPs, and then stained with a nucleic acid dye SYBR Green I (SYBR-I). After dual-labeling with FSiNPs and SYBR-I, the enriched E. coli O157:H7 was determined using multiparameter FCM analysis. With this method, the detection sensitivity was greatly improved due to the LMNPs enrichment and the signal amplification of the FSiNPs labelling method. Furthermore, the false positives caused by aggregates of FSiNPs conjugates and nonspecific binding of FSiNPs to background debris could be significantly decreased. This assay allowed the detection of E. coli O157:H7 in PB buffer at levels as low as 7 cells mL(-1). The total assay time including E. coli O157:H7 sample enrichment and detection was less than 4 h. An artificially contaminated bottled mineral water sample with a concentration of 6 cells mL(-1) can be detected by this method. It is believed that the proposed method will find wide applications in biomedical fields demanding higher sensitive bacterial identification.

Abstract
AIMS To identify and characterize a new adhesin-like protein of probiotics that show specific adhesion to human blood group A and B antigens. METHODS AND RESULTS Using the BIACORE assay, the adhesion of cell surface components obtained from four lactobacilli strains that adhered to blood group A and B antigens was tested. Their components showed a significant adhesion to A and B antigens when compared to the bovine serum albumin (BSA) control. The 1 mol l(-1) GHCl fraction extracted from Lactobacillus mucosae ME-340 contained a 29-kDa band (Lam29) using SDS-PAGE. The N-terminal amino acid sequence and homology analysis showed that Lam29 was 90% similar to the substrate-binding protein of the ATP-binding cassette (ABC) transporter from Lactobacillus fermentum IFO 3956. The complete nucleotide sequence (858 bp) of Lam29 was determined and encoded a protein of 285 amino acid residues. Phylogenetic analysis and multiple sequence alignments indicated this protein may be related to the cysteine-binding transporter. CONCLUSIONS The adhesion of ME-340 strain to blood group A and B antigens was mediated by Lam29 that is a putative component of ABC transporter as an adhesin-like protein. SIGNIFICANCE AND IMPACT OF THE STUDY Lactobacillus mucosae ME-340 expressing Lam29 may be useful for competitive exclusion of pathogens via blood group antigen receptors in the human gastrointestinal mucosa and in the development of new probiotic foods.

Abstract
The colonic mucus barrier is the first line of defence that the underlying mucosa has against the wide range of potentially damaging agents of microbial, endogenous, and dietary origin that occur within the colonic lumen. The functional component of mucus is the secreted, polymeric glycoprotein mucin. The mucus barrier can either act as an energy source or a support medium for growth to the intestinal microflora. The mucus barrier appears to effectively partition the vast number of microbial cells from the underlying epithelium. The normal functionality and biochemistry of this mucus barrier appears to be lost in diseases of the colorectal mucosa. Germ-free animal studies have highlighted the necessity of the presence of the colonic microflora to drive the maturation of the colonic mucosa and normal mucus production. A number of by-products of the microflora have been suggested to be key luminal drivers of colonic mucus secretion.

Abstract
Mucus-binding proteins (MUBs) have been revealed as one of the effector molecules involved in mechanisms of the adherence of lactobacilli to the host; mub, or mub-like, genes are found in all of the six genomes of Lactobacillus reuteri that are available. We recently reported the crystal structure of a Mub repeat from L. reuteri ATCC 53608 (also designated strain 1063), revealing an unexpected recognition of immunoglobulins. In the current study, we explored the diversity of the ATCC 53608 mub gene, and MUB expression levels in a large collection of L. reuteri strains isolated from a range of vertebrate hosts. This analysis revealed that the MUB was only detectable on the cell surface of two highly related isolates when using antibodies that were raised against the protein. There was considerable variation in quantitative mucus adhesion in vitro among L. reuteri strains, and mucus binding showed excellent correlation with the presence of cell-surface ATCC 53608 MUB. ATCC 53608 MUB presence was further highly associated with the autoaggregation of L. reuteri strains in washed cell suspensions, suggesting a novel role of this surface protein in cell aggregation. We also characterized MUB expression in representative L. reuteri strains. This analysis revealed that one derivative of strain 1063 was a spontaneous mutant that expressed a C-terminally truncated version of MUB. This frameshift mutation was caused by the insertion of a duplicated 13 nt sequence at position 4867 nt in the mub gene, producing a truncated MUB also lacking the C-terminal LPxTG region, and thus unable to anchor to the cell wall. This mutant, designated 1063N (mub-4867(i)), displayed low mucus-binding and aggregation capacities, further providing evidence for the contribution of cell-wall-anchored MUB to such phenotypes. In conclusion, this study provided novel information on the functional attributes of MUB in L. reuteri, and further demonstrated that MUB and MUB-like proteins, although present in many L. reuteri isolates, show a high genetic heterogeneity among strains.

Abstract
Escherichia coli O157:H7 is detected using a remote-query (wireless, passive) magnetoelastic sensor platform to which a 1 microm thick layer of Bayhydrol 110 and then a layer of functionalized mannose is applied. The multivalent binding of lectin concanavalin A (Con A) to the E. coli surface O-antigen and mannose favors the strong adhesion of E. coli to the mannose-modified magnetoelastic sensor; E. coli is rigidly and strongly attached on the mannose-modified sensor through Con A, which works as a bridge to bind E. coli to the mannose-modified sensor surface. As E. coli is bound to the sensor, its resonance frequency shifts, enabling quantification of E. coli concentration with a limit of detection of 60 cells/mL and a linear logarithmic response range of 6.0 x 10(1) to 6.1 x 10(9) cells/mL. The analysis can be directly conducted without incubation and completed in 3 h or less.

Abstract
Lactobacillus plantarum LA 318 is a potential probiotic strain isolated from normal human intestinal tissue that shows high adhesion to human colonic mucin mediated by the bacterial cell surface glyceraldehyde-3-phosphate dehydrogenase (GAPDH). We report the adhesion mechanism of the lactobacilli is in part due to GAPDH binding to human ABO-type blood group antigens expressed on human colonic mucin (HCM). After periodate oxidation of HCM, adhesion of L. plantarum LA 318 bacterial cells significantly decreased compared to normal HCM. A BIACORE binding assay of GAPDH to blood group antigens was then performed. High binding was observed to A and B group antigens, while binding to H group antigen was lower (P<0.01). No interaction was observed between GAPDH and various monosaccharides. Furthermore, GAPDH binding to the B-trisaccharide biotinyl polymer (BP)-probe [Galalpha1-3 (Fucalpha1-2) Gal-] was significantly higher as compared to B-disaccharide, Lewis D-trisaccharide, 3-fucosyl-N-acetylglucosamine and alpha-N-acetylneuraminic acid BP-probes. The data suggests the trisaccharide structure is important in binding to the blood group antigens. The binding of GAPDH to HCM significantly decreased after incubation with NAD+. This suggests that the NAD binding domain on GAPDH may be related to binding to HCM.

Abstract
AIMS To characterize the adhesion molecule of Lactobacillus plantarum LA 318 that shows high adhesion to human colonic mucin (HCM). METHODS AND RESULTS The adhesion test used the BIACORE assay where PBS-washed bacterial cells showed a significant decrease in adherence to HCM than distilled water-washed cells. A component in the PBS wash fraction adhered to the HCM and a main protein was detected as a c. 40-kDa band using SDS-PAGE. Using homology comparisons of the N-terminal amino acid sequences compared with sequence databases, this protein was identified as glyceraldehyde-3-phosphate dehydrogenase (GAPDH). The DNA sequence of LA 318 GAPDH was 100% identical to the GAPDH (gapB) of L. plantarum WCFS1. The purified GAPDH adhered to HCM. CONCLUSIONS We found the adhesin of L. plantarum LA 318 to HCM in its culture PBS wash fraction. The molecule was identified as GAPDH. Because LA 318 possesses the same adhesin as many pathogens, the lactobacilli GAPDH may compete with pathogens infecting the intestine. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first report showing GAPDH expressed on the cell surface of lactobacilli adheres to mucin suggesting L. plantarum LA 318 adheres to HCM using GAPDH binding activity to colonize the human intestinal mucosa.

Abstract
The safety of our food supply is always a major concern to consumers, food producers, and regulatory agencies. A safer food supply improves consumer confidence and brings economic stability. The safety of foods from farm-to-fork through the supply chain continuum must be established to protect consumers from debilitating, sometimes fatal episodes of pathogen outbreaks. The implementation of preventive strategies like hazard analysis critical control points (HACCP) assures safety but its full utility will not be realized unless supportive tools are fully developed. Rapid, sensitive, and accurate detection methods are such essential tools that, when integrated with HACCP, will improve safety of products. Traditional microbiological methods are powerful, error-proof, and dependable but these lengthy, cumbersome methods are often ineffective because they are not compatible with the speed at which the products are manufactured and the short shelf life of products. Automation in detection methods is highly desirable, but is not achievable with traditional methods. Therefore, biosensor-based tools offer the most promising solutions and address some of the modern-day needs for fast and sensitive detection of pathogens in real time or near real time. The application of several biosensor tools belonging to the categories of optical, electrochemical, and mass-based tools for detection of foodborne pathogens is reviewed in this chapter. Ironically, geometric growth in biosensor technology is fueled by the imminent threat of bioterrorism through food, water, and air and by the funding through various governmental agencies.

Abstract
AIMS To isolate lactobacilli from the mucus layer of the human intestine and evaluate their adhesion abilities using a BIACORE assay. METHODS AND RESULTS Thirty strains of lactobacilli were isolated from the mucus layer of normal human intestinal tissues using conventional plate culture. The strains were identified using homology comparisons of the 16S rDNA sequence to databases as Lactobacillus salivarius (26%), Lactobacillus fermentum (13%), Lactobacillus gasseri (10%), Lactobacillus paracasei (7%), Lactobacillus casei (3%), Lactobacillus mucosae (3%) and Lactobacillus plantarum (3%). Lactobacillus plantarum LA 318 shows the highest adhesion to human colonic mucin (HCM) using the BIACORE assay at 115.30 +/- 12.37 resonance unit (RU). The adhesion of cell wall surface proteins from strain LA 318 was significantly higher to HCM than to bovine serum albumin (BSA; P < 0.05). CONCLUSIONS We isolated 30 strains of lactobacilli. Lactobacillus salivarius was the predominant species of lactobacilli isolated in this study. The adhesion of strain LA 318 isolated from human transverse colon to its mucin was shown. The adhesion could be mediated by lectin-like components on the bacterial cell surface. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first study where lactobacilli were isolated from human intestinal tissues and shown to adhere to HCM.

Abstract
AIMS The objective of the present study was to explore the role of immobilized fructosyltransferase (FTF) in adhesion process. METHODS AND RESULTS We investigated real-time biospecific interactions between several types of oral bacteria and recombinant FTF immobilized on a biosensor chip, using surface plasmon resonance technology. Streptococcus mutans, Streptococcus sobrinus and Actinomyces viscosus demonstrated significant binding to FTF. Actinomyces viscosus had a greater binding to FTF, with 373 Resonance Units (RU), than the other tested bacteria. The binding level to FTF of Strep. sobrinus was 320 RU, whereas Strep. mutans and Streptococcus salivarious show binding of 296 and 245 RU, respectively. The binding sensograms displayed different profiles for the tested bacteria at various cell density, suggesting a different affinity to immobilized FTF. CONCLUSIONS The results from this study suggest that FTF may influence bacterial adherence and colonization of the dental biofilm. SIGNIFICANCE AND IMPACT OF THE STUDY The biomolecular interaction analysis enables real-time monitoring of the interaction between adhesions of intact bacteria and their ligands, which might be crucial in the initial phase of biofilm development in vivo.

Abstract
Adherent lactic acid bacteria (LAB) in the human intestine were investigated using the surface plasmon resonance technique with the biosensor BIACORE-1000. Ninety-three LAB strains were isolated from human feces and evaluated for binding to human blood type-A antigen [GalNAcalpha1-3 (Fucalpha1-2) Gal-: A-trisaccharide] expressed in the intestinal mucosa. Eleven strains showed strong adherence to an A-trisaccharide biotinyl polymer (BP) probe, and slightly or no adherence to a B-trisaccharide BP probe. Four strains with high adherence (high A/B ratio) were selected and their surface layer proteins (SLPs) were evaluated for A-antigen ligand binding using BIACORE. The SLP from L. brevis strain OLL2772 showed a single band at ca. 48 kDa by SDS-PAGE analysis and it had a very strong adherence to the human A-antigen, as shown using an anti-A lectin blocking technique. A partial N-terminal sequence of the band showed strong homology to an S-layer protein of L. brevis ATCC8287T. The probiotic LAB binds to human blood type-A antigen expressed in the intestinal mucosa which may aid in colonization of the gut.

Abstract
The year 2004 represents a milestone for the biosensor research community: in this year, over 1000 articles were published describing experiments performed using commercially available systems. The 1038 papers we found represent an approximately 10% increase over the past year and demonstrate that the implementation of biosensors continues to expand at a healthy pace. We evaluated the data presented in each paper and compiled a 'top 10' list. These 10 articles, which we recommend every biosensor user reads, describe well-performed kinetic, equilibrium and qualitative/screening studies, provide comparisons between binding parameters obtained from different biosensor users, as well as from biosensor- and solution-based interaction analyses, and summarize the cutting-edge applications of the technology. We also re-iterate some of the experimental pitfalls that lead to sub-optimal data and over-interpreted results. We are hopeful that the biosensor community, by applying the hints we outline, will obtain data on a par with that presented in the 10 spotlighted articles. This will ensure that the scientific community at large can be confident in the data we report from optical biosensors.
