Abstract
China faces a persistent deficiency in feed protein resources. Enhancing the utilization efficiency of indigenous feed protein resources emerges as a viable strategy to alleviate the current deficit in protein feed supply. Corn gluten meal (CGM), characterized by a high proportion of crude protein and glutamine, is predominantly employed in animal feed. Nonetheless, the water-insolubility of CGM protein hampers its protein bioavailability when utilized as feed material. The aim of this study was to augment protein bioavailability, liberate glutamine peptides from CGM, and produce glutamine-enriched CGM fermented feed. We executed a co-fermentation protocol using Bacillus subtilis A5, Lactobacillus 02002, and acid protease to generate the CGM fermented feed. Subsequent in vivo experiments with broilers were conducted to assess the efficacy of the fermented product. The findings revealed that the soluble protein, glutamine, small peptides, and lactic acid contents in the fermented feed increased by 69.1%, 700%, 47.6%, and 125.9%, respectively. Incorporating 15% and 30% CGM fermented feed into the diet markedly enhanced the growth performance and intestinal health of broilers, positively modulated the cecal microbiota structure, and augmented the population of beneficial bacteria, specifically Lactobacillus. These results furnish both experimental and theoretical foundations for deploying CGM fermented feed as an alternative protein feed resource.

Int J Biol Macromol 2022; 216:871-881.

Abstract
The effects of high exopolysaccharides (EPS) - producing Lactobacillus helveticus MB2-1 on the structure and storage stability of set yoghurts, and the interactions between its EPS (molecular weight 9.34 × 104 Da) from Sayram ketteki yoghurt (SKY) and sodium caseinate (CAS) were studied. The rheology, microstructure, texture and storage stability of the three set yoghurts including control yoghurt (Control), adding-probiotic yoghurt (APY) and SKY were investigated, which showed that the SKY exhibited less shear thinning than the Control and APY, and the textural indexes and storage stability of the SKY were significantly better than that of other two yoghurts (p < 0.05). Moreover, the increased turbidity, decreased ζ potential and surface hydrophobicity of EPS/CAS complex coacervation were determined at EPS/CAS mass ratio of 3 (corresponding to 0.33 g/L of CAS and 1 g/L of EPS), mainly owing to the electrostatic attraction of the two biopolymers to form aggregates. Besides, the higher sizes and more aggregation of EPS/CAS complexes were formed at pH 3.5. Taken together, the results indicated that the high EPS-producing characteristic of L. helveticus MB2-1 could positively influence the qualities of set yoghurts, and the EPS/CAS complex coacervation in dairy products was closely related to the EPS/CAS mass ratio and pH condition.

Abstract
The present study investigated the impact of probiotic Lactobacillus reuteri LR6 on the gut and systemic immunity using protein energy malnourished (PEM) murine model. Thirty male Swiss albino mice were divided into five groups: control (C), malnourished (M), probiotic fermented milk (PFM), skim milk (SM), and bacterial suspension (BS) with six mice per group. Group C was fed with conventional diet throughout the study while the other groups were fed with protein calorie restricted diet until the development of malnutrition. After development of malnutrition, group M was continued with the restricted diet while other groups were fed with re-nourished diet supplemented with PFM, SM, and BS for 1 week, respectively. Thereafter, mice were sacrificed and different histological, microbiological, and immunological parameters were studied. Probiotics feeding in PEM model as fermented product or bacterial suspension improved the intestinal health in terms of intact morphology of colonic crypts, normal goblet cells, and intact lamina propria with no inflammation in large intestine, absence of fibrosis, and no inflammation in spleen. The number of secretory IgA+ cells was significantly higher in group PFM and BS. Also, increase in the phagocytic percentage of the macrophages and bone marrow derived dendritic cells (DCs) were observed in the PFM and BS group in comparison to the group M. In comparison to the group M and SM, lactobacilli, bifidobacteria, and Firmicutes counts were significantly higher in the group PFM and BS. This study concludes that probiotic supplementation to re-nutrition diet could emerge as wonder therapeutics against PEM.

Abstract
Regulation on gut microbiota and short-chain fatty acids (SCFAs) are believed to be a pathway to suppress the development of metabolic syndrome. In this study, three Lactobacillus strains derived from the human gut were investigated for their effects on alleviation of metabolic disorders. These strains were individually administered to metabolic disorder rats induced by high-fat-high-sucrose (HFHS) diet. Each strain exhibited its own characteristics in attenuating the impaired glucose-insulin homeostasis, hepatic oxidative damage and steatosis. Correlation analysis between SCFAs and host metabolic parameters suggested that Lactobacillus protective effects on metabolic disorders are partly mediated by recovery of SCFAs production, especially the faecal acetic acid. Correspondingly, it indicated that probiotics restore the gut microbiota dysbiosis in different extent, thereby protect against metabolic disorders in a manner that is associated with microbiota, but not totally reverse the changed composition of microbiota to the normal state. Thus, Lactobacillus strains partly protect against diet-induced metabolic syndrome by microbiota modulation and acetate elevation.

Abstract
In order to inhibit pathogenic complications and to enhance animal and poultry growth, antibiotics have been extensively used for many years. Antibiotics applications not only affect target pathogens but also intestinal beneficially microbes, inducing long-lasting changes in intestinal microbiota associated with diseases. The application of antibiotics also has many other side effects like, intestinal barrier dysfunction, antibiotics residues in foodstuffs, nephropathy, allergy, bone marrow toxicity, mutagenicity, reproductive disorders, hepatotoxicity carcinogenicity, and antibiotic-resistant bacteria, which greatly compromise the efficacy of antibiotics. Thus, the development of new antibiotics is necessary, while the search for antibiotic alternatives continues. Probiotics are considered the ideal antibiotic substitute; in recent years, probiotic research concerning their application during pathogenic infections in humans, aquaculture, poultry, and livestock industry, with emphasis on modulating the immune system of the host, has been attracting considerable interest. Hence, the adverse effects of antibiotics and remedial effects of probiotics during infectious diseases have become central points of focus among researchers. Probiotics are live microorganisms, and when given in adequate quantities, confer good health effects to the host through different mechanisms. Among them, the regulation of host immune response during pathogenic infections is one of the most important mechanisms. A number of studies have investigated different aspects of probiotics. In this review, we mainly summarize recent discoveries and discuss two important aspects: (1) the application of probiotics during pathogenic infections; and (2) their modulatory effects on the immune response of the host during infectious and non-infectious diseases.

Cell surface and extracellular proteins of potentially probiotic Lactobacillus reuteri as an effective mediator to regulate intestinal epithelial barrier function. Arch Microbiol 2021; 203:3219-3228.

Abstract
The present study aimed to evaluate the potential of cell surface and extracellular proteins in regulation of intestinal epithelial barrier (IEB) function. Eight potentially probiotic L. reuteri strains were evaluated for presence of mapA gene and its expression on co-culturing with the Caco-2 cells. The ability of untreated (Viable), heat-inactivated, 5 M LiCL treated L. reuteri strains as well as their cell-free supernatant (CFS) to modulate expression of IEB function genes (hBD-2, hBD-3, claudin-1 and occludin) was also evaluated. Caco-2 cells were treated with cell surface and extracellular protein extracts and investigated for change in expression of targeted IEB function genes. The results showed that mapA gene is present in all the tested L. reuteri strains and expression of mapA and its receptors (anxA13 and palm) increase significantly on co-culturing of L. reuteri and Caco-2 cells. Also, up-regulated expression of IEB function genes was observed on co-culturing of L. reuteri (viable, heat-inactivated and CFS) and their protein extracts with Caco-2 cells in contrast to down-regulation observed with the pathogenic strain of Salmonella typhi. Therefore, this study concludes that the cell surface and extracellular protein from L. reuteri act as an effective mediator molecules to regulate IEB function.
